1 2436 100 YOGA AND PSYCHIATRIC DISORDERS: A REVIEW OF BIOMARKER EVIDENCE. TRADITIONALLY, YOGA HAS BEEN USED AS A MEANS FOR SPIRITUAL GROWTH BUT OVER THE PAST TWO DECADES OR SO ITS THERAPEUTIC BENEFITS IN PSYCHIATRIC DISORDERS HAVE BEEN SCIENTIFICALLY EXPLORED. YOGA HAS BEEN SHOWN TO BE USEFUL AS A MONO-THERAPY IN MILD TO MODERATE DEPRESSION AND AS AN ADJUVANT IN SEVERAL PSYCHIATRIC DISORDERS INCLUDING SCHIZOPHRENIA, ANXIETY DISORDERS, SUBSTANCE USE DISORDERS AND MILD COGNITIVE IMPAIRMENT. FURTHERMORE, SYSTEMATIC ATTEMPTS HAVE BEEN MADE TO UNDERSTAND THE BIOLOGICAL CORRELATES OF YOGA IN THESE PSYCHIATRIC DISORDERS. GIVEN THAT NO PSYCHIATRIC DISORDER HAS STRONG AND ESTABLISHED BIOMARKERS, IT IS INTERESTING THAT PRELIMINARY RESEARCH HAS DEMONSTRATED SIGNIFICANT CHANGES IN CERTAIN IMPORTANT BIOMARKERS FOLLOWING REGULAR YOGA PRACTICE. IN THIS BRIEF REVIEW, WE PROVIDE AN UPDATE ON THE EFFECTS OF YOGA ON BIOCHEMICAL, NEURO-PHYSIOLOGICAL AND NEURO-IMAGING RELATED BIO-MARKERS IN PSYCHIATRIC DISORDERS. ALTHOUGH FINDINGS AND TRENDS ARE PROMISING, MUCH MORE RESEARCH IS WARRANTED TO ESTABLISH A DEFINITE BIOLOGICAL BASIS FOR YOGA IN PSYCHIATRY.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
2 2369  32 WHAT ARE THE KNOWN EFFECTS OF YOGA ON THE BRAIN IN RELATION TO MOTOR PERFORMANCES, BODY AWARENESS AND PAIN? A NARRATIVE REVIEW. OBJECTIVE: THE CURRENT BODY OF LITERATURE WAS REVIEWED TO EVALUATE THE EFFECTS OF YOGA ON THE BRAIN IN RELATION TO MOTOR PERFORMANCE, BODY AWARENESS AND PAIN. BACKGROUND: YOGA HAS BEEN INCREASINGLY POPULAR IN THE WESTERN COUNTRIES ESPECIALLY FOR ITS UNIQUE INTEGRATION OF THE MIND AND BODY. YOGA HAS BEEN STUDIED MORE INTENSELY IN THE LAST DECADE. ALTHOUGH IT HAS BEEN SHOWN TO IMPROVE COGNITIVE FUNCTIONS, FEW STUDIES HAVE LOOKED INTO THE EFFECTS OF YOGA ON IMPROVING MOTOR PERFORMANCE, BODY AWARENESS OR PAIN AND THE POSSIBLE UNDERLYING BRAIN MECHANISMS ASSOCIATED WITH THEM. METHODS: A SEARCH OF THE CURRENT LITERATURE WAS MADE USING KEYWORDS SUCH AS: "YOGA BRAIN MOTOR", "YOGA BRAIN PAIN", "EFFECTS YOGA BRAIN" AND "EFFECTS YOGA BRAIN MOTOR PERFORMANCE". THE FINDINGS WERE THEN DISCUSSED IN RELATION TO MOTOR PERFORMANCE, BODY AWARENESS AND PAIN AND THEIR REPORTED MECHANISMS OF ACTION ON THE BRAIN. RESULTS: A TOTAL OF 61 ARTICLES WERE SELECTED, OUT OF WHICH 29 WERE EXCLUDED BECAUSE THEY DID NOT MEET OUR CRITERIA. A TOTAL OF THIRTY-TWO ARTICLES WERE INCLUDED IN THIS REVIEW, WHICH WE FURTHER SUBDIVIDED BY FOCUS: MOTOR PERFORMANCE (N=10), BODY AWARENESS (N=14) AND PAIN (N=8). DISCUSSION: OUR REVIEW SHOWS THAT YOGA HAS A POSITIVE EFFECT ON LEARNING RATE, SPEED AND ACCURACY OF A MOTOR TASK BY INCREASING ATTENTION AND DECREASING STRESS THROUGH A BETTER CONTROL OF SENSORIMOTOR RHYTHMS. YOGA ALSO SEEMS TO IMPROVE SENSORY AWARENESS AND INTEROCEPTION, REGULATE AUTONOMIC INPUT, INCREASE PARASYMPATHETIC ACTIVITY AND PROMOTE SELF-REGULATION. YOGA WAS ALSO SHOWN TO REDUCE THE THREAT SIGNAL, INCREASE PAIN TOLERANCE, DECREASE PAIN UNPLEASANTNESS AND DECREASE THE ANXIETY AND DISTRESS ASSOCIATED WITH PAIN. THOSE CHANGES ARE ASSOCIATED WITH THE RECRUITMENT OF SPECIFIC BRAIN AREAS SUCH AS THE INSULA, THE AMYGDALA AND THE HIPPOCAMPUS. CONCLUSION: BASED ON THE STUDIES REVIEWED IN THIS REPORT, WE FOUND THAT THE PRACTICE OF YOGA SEEMS TO FACILITATE MOTOR LEARNING, TO INCREASE BODY AWARENESS AND TO DECREASE PAIN. THESE ARE ASSOCIATED WITH A WIDE VARIETY OF CHANGES IN TERMS OF BRAIN ACTIVITY AND STRUCTURE. FURTHER STUDIES ARE NECESSARY TO REVEAL ITS PRECISE MECHANISM OF ACTION ON THE BRAIN AND TO VALIDATE ITS WIDER APPLICATION IN CLINICAL SETTINGS.	2019	

3  272  22 ADD-ON YOGA THERAPY FOR SOCIAL COGNITION IN SCHIZOPHRENIA: A PILOT STUDY. BACKGROUND: YOGA AS A MIND-BODY THERAPY IS USEFUL IN LIFESTYLE-RELATED DISORDERS INCLUDING NEUROPSYCHIATRIC DISORDERS. IN SCHIZOPHRENIA PATIENTS, YOGA HAS BEEN SHOWN TO SIGNIFICANTLY IMPROVE NEGATIVE SYMPTOMS, FUNCTIONING, AND PLASMA OXYTOCIN LEVEL. AIM: THE AIM OF THE STUDY WAS TO STUDY THE EFFECT OF ADD-ON YOGA THERAPY ON SOCIAL COGNITION IN SCHIZOPHRENIA PATIENTS. MATERIALS AND METHODS: IN A SINGLE PRE-POST, STUDY DESIGN, 15 SCHIZOPHRENIA PATIENTS STABILIZED ON ANTIPSYCHOTIC MEDICATION FOR 6 WEEKS WERE ASSESSED FOR SOCIAL COGNITION (THEORY OF MIND, FACIAL EMOTION RECOGNITION, AND SOCIAL PERCEPTION [SP]) AND CLINICAL SYMPTOMS (NEGATIVE AND POSITIVE SYMPTOMS AND SOCIAL DISABILITY) BEFORE AND AFTER TWENTY SESSIONS OF ADD-ON YOGA THERAPY. RESULTS: THERE WAS A SIGNIFICANT IMPROVEMENT IN THE SOCIAL COGNITION COMPOSITE SCORE AFTER 20 SESSIONS OF YOGA (T[13] = -5.37, P </= 0.001). CLINICAL SYMPTOMS ALSO REDUCED SIGNIFICANTLY AFTER TWENTY SESSIONS OF YOGA. CONCLUSION: RESULTS ARE PROMISING TO INTEGRATE YOGA IN CLINICAL PRACTICE, IF PROVEN IN WELL-CONTROLLED CLINICAL TRIALS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
4 2798  34 YOGA THERAPY FOR SCHIZOPHRENIA. SCHIZOPHRENIA IS ONE OF THE MOST SEVERE MENTAL DISORDERS. DESPITE SIGNIFICANT ADVANCES IN PHARMACOTHERAPY, TREATMENT REMAINS SUB-OPTIMAL, WITH MANY PATIENTS HAVING PERSISTING DEFICITS, ESPECIALLY IN COGNITIVE AND SOCIAL FUNCTIONING. YOGA AS A THERAPY HAS PROVEN TO BE EFFECTIVE AS A SOLE OR ADDITIONAL INTERVENTION IN PSYCHIATRIC DISORDERS SUCH AS DEPRESSION AND ANXIETY. RECENTLY, THERE HAS BEEN SIGNIFICANT INTEREST IN THE APPLICATION OF YOGA THERAPY IN PSYCHOSIS AND SCHIZOPHRENIA. TO REVIEW A) THE EVIDENCE FOR THE USE OF YOGA THERAPY IN PATIENTS WITH SCHIZOPHRENIA B) STUDIES WHICH HAVE BEEN DONE IN THIS AREA, C) THE BARRIERS FOR REACHING YOGA TO PATIENTS, AND D) FUTURE DIRECTIONS, AN ENGLISH LANGUAGE LITERATURE SEARCH OF PUBMED/MEDLINE, GOOGLE SCHOLAR, AND EBSCO AS WELL AS GREY LITERATURE WAS DONE. RESEARCH REPORTS HAVE DEMONSTRATED THE FEASIBILITY AND EFFICACY OF YOGA AS AN ADD-ON THERAPY IN SCHIZOPHRENIA, PARTICULARLY IN IMPROVING NEGATIVE SYMPTOMATOLOGY AND SOCIAL COGNITION. HOWEVER, THE BIOLOGICAL UNDERPINNINGS OF THIS EFFECT REMAIN UNCLEAR, ALTHOUGH THERE ARE SOME INDICATIONS THAT HORMONES LIKE OXYTOCIN MAY CONTRIBUTE TO THE CHANGES IN SOCIAL COGNITION.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
5 2277  21 THE ROLES OF EXERCISE AND YOGA IN AMELIORATING DEPRESSION AS A RISK FACTOR FOR COGNITIVE DECLINE. CURRENTLY, THERE ARE NO EFFECTIVE PHARMACEUTICAL TREATMENTS TO REDUCE COGNITIVE DECLINE OR PREVENT DEMENTIA. AT THE SAME TIME, THE GLOBAL POPULATION IS AGING, AND RATES OF DEMENTIA AND MILD COGNITIVE IMPAIRMENT (MCI) ARE ON THE RISE. AS SUCH, THERE IS AN INCREASING INTEREST IN COMPLEMENTARY AND ALTERNATIVE INTERVENTIONS TO TREAT OR REDUCE THE RISK OF COGNITIVE DECLINE. DEPRESSION IS ONE POTENTIALLY MODIFIABLE RISK FACTOR FOR COGNITIVE DECLINE AND DEMENTIA. NOTABLY, EXERCISE AND YOGA ARE TWO INTERVENTIONS KNOWN TO BOTH REDUCE SYMPTOMS OF DEPRESSION AND IMPROVE COGNITIVE FUNCTION. THE CURRENT REVIEW DISCUSSES THE EFFICACY OF EXERCISE AND YOGA TO AMELIORATE DEPRESSION AND THEREBY REDUCE THE RISK OF COGNITIVE DECLINE AND POTENTIALLY PREVENT DEMENTIA. POTENTIAL MECHANISMS OF CHANGE, TREATMENT IMPLICATIONS, AND FUTURE DIRECTIONS ARE DISCUSSED.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
6 1920  39 ROLE OF YOGA AND MINDFULNESS IN SEVERE MENTAL ILLNESSES: A NARRATIVE REVIEW. BACKGROUND: YOGA HAS ITS ORIGIN FROM THE ANCIENT TIMES. IT IS AN INTEGRATION OF MIND, BODY, AND SOUL. BESIDES, MINDFULNESS EMPHASIZES FOCUSED AWARENESS AND ACCEPTING THE INTERNAL EXPERIENCES WITHOUT BEING JUDGEMENTAL. THESE TECHNIQUES OFFER A TRENDING NEW DIMENSION OF TREATMENT IN VARIOUS PSYCHIATRIC DISORDERS. AIMS: WE AIMED TO REVIEW THE STUDIES ON THE EFFICACY OF YOGA AND MINDFULNESS AS A TREATMENT MODALITY IN SEVERE MENTAL ILLNESSES (SMIS). SMI INCLUDES SCHIZOPHRENIA, MAJOR DEPRESSIVE DISORDER (MDD), AND BIPOLAR DISORDER (BD). METHODS: WE CONDUCTED A LITERATURE SEARCH USING PUBMED, GOOGLE SCHOLAR, AND COCHRANE LIBRARY WITH THE SEARCH TERMS "YOGA," "MEDITATION," "BREATHING EXERCISES," "MINDFULNESS," "SCHIZOPHRENIA SPECTRUM AND OTHER PSYCHOTIC DISORDERS," "DEPRESSIVE DISORDER," AND "BIPOLAR DISORDER" FOR THE LAST 10-YEAR PERIOD. WE ALSO INCLUDED RELEVANT ARTICLES FROM THE CROSS-REFERENCES. RESULTS: WE FOUND THAT ASANAS AND PRANAYAMA ARE THE MOST COMMONLY STUDIED FORMS OF YOGA FOR SCHIZOPHRENIA. THESE STUDIES FOUND A REDUCTION IN GENERAL PSYCHOPATHOLOGY RATINGS AND AN IMPROVEMENT IN COGNITION AND FUNCTIONING. SOME STUDIES ALSO FOUND MODEST BENEFITS IN NEGATIVE AND POSITIVE SYMPTOMS. MINDFULNESS HAS NOT BEEN EXTENSIVELY TRIED, BUT THE AVAILABLE EVIDENCE HAS SHOWN BENEFITS IN IMPROVING PSYCHOTIC SYMPTOMS, IMPROVING LEVEL OF FUNCTIONING, AND AFFECT REGULATION. IN MDD, BOTH YOGA AND MINDFULNESS HAVE DEMONSTRATED SIGNIFICANT BENEFIT IN REDUCING THE SEVERITY OF DEPRESSIVE SYMPTOMS. THERE IS VERY SPARSE DATA WITH RESPECT TO BD. CONCLUSION: BOTH YOGA AND MINDFULNESS INTERVENTIONS APPEAR TO BE USEFUL AS AN ADJUNCT IN THE TREATMENT OF SMI. STUDIES HAVE SHOWN IMPROVEMENT IN THE PSYCHOPATHOLOGY, ANXIETY, COGNITION, AND FUNCTIONING OF PATIENTS WITH SCHIZOPHRENIA. SIMILARLY, BOTH THE TECHNIQUES HAVE BEEN ESTABLISHED AS AN EFFECTIVE ADJUVANT IN MDD. HOWEVER, MORE RIGOROUSLY DESIGNED AND LARGER TRIALS MAY BE NECESSARY, SPECIFICALLY FOR BD.	2019	
                                                                                                                                                                                                                                                                                                                                                           
7 2670  23 YOGA IN PREGNANCY. YOGA IS A MIND-BODY PRACTICE THAT ENCOMPASSES A SYSTEM OF POSTURES (ASANA), DEEP BREATHING (PRANAYAMA), AND MEDITATION. OVER 36 MILLION AMERICANS PRACTICE YOGA OF WHICH THE MAJORITY ARE REPRODUCTIVE-AGED WOMEN. LITERATURE TO SUPPORT THIS PRACTICE IS LIMITED, ALBEIT ON THE RISE. A PRENATAL YOGA PRACTICE HAS BEEN SHOWN TO BENEFIT WOMEN WHO SUFFER FROM ANXIETY, DEPRESSION, STRESS, LOW BACK PAIN, AND SLEEP DISTURBANCES. A SMALL NUMBER OF STUDIES HAVE BEEN PERFORMED IN HIGH-RISK PREGNANCIES THAT ALSO DEMONSTRATE AN IMPROVEMENT IN OUTCOMES. THE SAFETY OF PERFORMING YOGA FOR THE FIRST TIME IN PREGNANCY AND FETAL TOLERANCE HAS BEEN DEMONSTRATED.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
8  644  25 DOES YOGA HAVE A ROLE IN SCHIZOPHRENIA MANAGEMENT? PURPOSE OF REVIEW: TO REVIEW THE EFFICACY OF ADD-ON YOGA THERAPY IN IMPROVING SYMPTOMS OF SCHIZOPHRENIA AND QUALITY OF LIFE AND EXAMINE THE POSSIBLE UNDERLYING BIOLOGICAL MECHANISMS OF YOGA IN SCHIZOPHRENIA. RECENT FINDINGS: QUALITY OF LIFE, COGNITIVE SYMPTOMS, AND NEGATIVE SYMPTOMS HAVE BEEN FOUND TO IMPROVE WITH ADD-ON YOGA THERAPY IN SCHIZOPHRENIA (POOLED MEAN EFFECT SIZE 0.8, 0.6, AND 0.4, RESPECTIVELY). YOGA ALSO SEEMS TO HAVE A SMALL EFFECT ON IMPROVING POSITIVE SYMPTOMS. LESS EXPLORED AREAS INCLUDE ADVERSE EFFECTS OF YOGA ITSELF AS WELL AS ITS EFFECTS ON ANTIPSYCHOTIC-INDUCED COMPLICATIONS. PRELIMINARY FINDINGS SUGGEST THAT THE EFFECTS OF YOGA MAY BE MEDIATED BY NEUROHORMONAL MECHANISMS AND FUNCTIONAL CHANGES IN BRAIN ACTIVITY. ADD-ON YOGA THERAPY IS A POTENTIAL TREATMENT OPTION FOR IMPROVING QUALITY OF LIFE, COGNITIVE SYMPTOMS, AND NEGATIVE SYMPTOMS IN SCHIZOPHRENIA. FUTURE STUDIES SHOULD EXPLORE EFFICACY IN MULTICENTRIC TRIALS AS WELL AS POSSIBLE NEUROBIOLOGICAL CHANGES UNDERLYING THE EFFECTS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
9  406  39 BIOLOGICAL MARKERS FOR THE EFFECTS OF YOGA AS A COMPLEMENTARY AND ALTERNATIVE MEDICINE. FROM THE LAST FEW DECADES, THERE ARE INCREASING INCIDENCES OF DISORDERS LIKE PREMATURE AGING, CARDIOVASCULAR DISEASE, MULTIPLE SCLEROSIS, FIBROMYALGIA, AND ALZHEIMER'S DISEASE IN ADDITION TO MEDICATION, RESEARCHERS HAVE FOUND THAT YOGA, A MIND-BODY THERAPY, CAN BE USED AS AN ALTERNATIVE MEDICINE. YOGA COMBINES SPECIFIC PHYSICAL POSTURES, BREATHING TECHNIQUES, RELAXATION AND MEDITATION THAT IMPROVE MENTAL AND PHYSICAL HEALTH OF THE BODY. THE PURPOSE OF THIS REVIEW IS TO COLLATE THE RESEARCH EVIDENCES CLAIMING HEALTH BENEFITS OF PERFORMING TRADITIONAL YOGIC PRACTICES. WHAT ARE THE BIOLOGICAL AND OTHER RELIABLE INDICATORS TO SUGGEST THAT DOING ASANAS, PRANAYAMA, AND MEDITATION COULD REDUCE OR TREAT WIDE RANGE OF LIFE STYLE DISORDERS ARE DISCUSSED. IMPORTANTLY, THESE INDICATORS ARE OTHERWISE USED TO ASSESS THE SEVERITY OF DISORDERS. IN MANY OF THE STUDY IT HAS BEEN SHOWN THAT YOGA IMPROVES THE REDOX HEALTH OF BODY WHOSE IMBALANCE HAS BEEN WELL PROVEN TO CAUSE MANY HEALTH COMPLICATIONS. THE IMPACT OF YOGA ON NEURODEGENERATIVE DISEASES HAVE REVEALED THAT IT REVERSES MEMORY LOSS, REDUCE ANXIETY, DEPRESSION AND STRESS, THE BIOLOGICAL INDICATORS OF DISEASE. HOWEVER, MOST STUDIES HAVE SEVERAL LIMITATIONS AND THEREFORE FURTHER RESEARCH INTO YOGA IS NEEDED TO VALIDATE THESE FINDINGS.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
10 2014  31 SUDARSHAN KRIYA YOGA: BREATHING FOR HEALTH. BREATHING TECHNIQUES ARE REGULARLY RECOMMENDED FOR RELAXATION, STRESS MANAGEMENT, CONTROL OF PSYCHOPHYSIOLOGICAL STATES, AND TO IMPROVE ORGAN FUNCTION. YOGIC BREATHING, DEFINED AS A MANIPULATION OF BREATH MOVEMENT, HAS BEEN SHOWN TO POSITIVELY AFFECT IMMUNE FUNCTION, AUTONOMIC NERVOUS SYSTEM IMBALANCES, AND PSYCHOLOGICAL OR STRESS-RELATED DISORDERS. THE AIM OF THIS STUDY WAS TO ASSESS AND PROVIDE A COMPREHENSIVE REVIEW OF THE PHYSIOLOGICAL MECHANISMS, THE MIND-BODY CONNECTION, AND THE BENEFITS OF SUDARSHAN KRIYA YOGA (SKY) IN A WIDE RANGE OF CLINICAL CONDITIONS. VARIOUS ONLINE DATABASES SEARCHED WERE MEDLINE, PSYCHINFO, EMBASE, AND GOOGLE SCHOLAR. ALL THE RESULTS WERE CAREFULLY SCREENED AND ARTICLES ON SKY WERE SELECTED. THE REFERENCES FROM THESE ARTICLES WERE CHECKED TO FIND ANY OTHER POTENTIALLY RELEVANT ARTICLES. SKY, A UNIQUE YOGIC BREATHING PRACTICE, INVOLVES SEVERAL TYPES OF CYCLICAL BREATHING PATTERNS, RANGING FROM SLOW AND CALMING TO RAPID AND STIMULATING. THERE IS MOUNTING EVIDENCE TO SUGGEST THAT SKY CAN BE A BENEFICIAL, LOW-RISK, LOW-COST ADJUNCT TO THE TREATMENT OF STRESS, ANXIETY, POST-TRAUMATIC STRESS DISORDER, DEPRESSION, STRESS-RELATED MEDICAL ILLNESSES, SUBSTANCE ABUSE, AND REHABILITATION OF CRIMINAL OFFENDERS.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
11  831  25 EFFECT OF YOGA ON MIGRAINE: A COMPREHENSIVE STUDY USING CLINICAL PROFILE AND CARDIAC AUTONOMIC FUNCTIONS. CONTEXT AND AIMS: MIGRAINE IS AN EPISODIC DISABLING HEADACHE REQUIRING LONG-TERM MANAGEMENT. MIGRAINE MANAGEMENT THROUGH YOGA THERAPY WOULD REDUCE THE MEDICATION COST WITH POSITIVE HEALTH BENEFITS. YOGA HAS SHOWN TO IMPROVE THE QUALITY OF LIFE, REDUCE THE EPISODE OF HEADACHE AND MEDICATION. THE AIM OF THE PRESENT STUDY WAS TO EVALUATE THE EFFICACY OF YOGA AS AN ADJUVANT THERAPY IN MIGRAINE PATIENTS BY ASSESSING CLINICAL OUTCOME AND AUTONOMIC FUNCTIONS TESTS. SUBJECTS AND METHODS: MIGRAINE PATIENTS WERE RANDOMLY GIVEN EITHER CONVENTIONAL CARE (N = 30) OR YOGA WITH CONVENTIONAL CARE (N = 30). YOGA GROUP RECEIVED YOGA PRACTICE SESSION FOR 5 DAYS A WEEK FOR 6 WEEKS ALONG WITH CONVENTIONAL CARE. CLINICAL ASSESSMENT (FREQUENCY, INTENSITY OF HEADACHE AND HEADACHE IMPACT) AND AUTONOMIC FUNCTION TEST WERE DONE AT BASELINE AND AT THE END OF THE INTERVENTION. RESULTS: YOGA WITH CONVENTIONAL CARE AND CONVENTION CARE GROUPS SHOWED SIGNIFICANT IMPROVEMENT IN CLINICAL VARIABLES, BUT IT WAS BETTER WITH YOGA THERAPY. IMPROVEMENT IN THE VAGAL TONE ALONG WITH REDUCED SYMPATHETIC ACTIVITY WAS OBSERVED IN PATIENTS WITH MIGRAINE RECEIVING YOGA AS ADJUVANT THERAPY. CONCLUSIONS: INTERVENTION SHOWED SIGNIFICANT CLINICAL IMPROVEMENT IN BOTH GROUPS. HEADACHE FREQUENCY AND INTENSITY WERE REDUCED MORE IN YOGA WITH CONVENTIONAL CARE THAN THE CONVENTIONAL CARE GROUP ALONE. FURTHERMORE, YOGA THERAPY ENHANCED THE VAGAL TONE AND DECREASED THE SYMPATHETIC DRIVE, HENCE IMPROVING THE CARDIAC AUTONOMIC BALANCE. THUS, YOGA THERAPY CAN BE EFFECTIVELY INCORPORATED AS AN ADJUVANT THERAPY IN MIGRAINE PATIENTS.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
12 1927  28 ROLE OF YOGA IN CARDIAC DISEASE AND REHABILITATION. PURPOSE: CARDIOVASCULAR DISEASE CONTINUES TO BE THE LEADING CAUSE OF MORBIDITY AND MORTALITY AROUND THE WORLD. YOGA, A COMBINATION OF PHYSICAL POSTURES (ASANA), BREATHING EXERCISES (PRANAYAMA), AND MEDITATION (DHYANA), HAS GAINED INCREASING RECOGNITION AS A FORM OF MIND-BODY EXERCISE. IN THIS NARRATIVE REVIEW, WE INTENDED TO REVIEW THE EMERGING EVIDENCE ASSESSING THE PHYSIOLOGIC AND CLINICAL EFFECTS OF YOGA ON THE CARDIOVASCULAR SYSTEM AND THE POTENTIAL ROLE OF YOGA AS A COMPONENT OF COMPREHENSIVE CARDIAC REHABILITATION. METHODS: WE SEARCHED PUBMED, GOOGLE SCHOLAR, EMBASE, AND COCHRANE DATABASES FOR LITERATURE RELATED TO CARDIOVASCULAR EFFECTS OF YOGA FROM INCEPTION UP UNTIL 2017. RESULTS: YOGA HAS BEEN SHOWN TO HAVE FAVORABLE EFFECTS ON SYSTEMIC INFLAMMATION, STRESS, THE CARDIAC AUTONOMIC NERVOUS SYSTEM, AND TRADITIONAL AND EMERGING CARDIOVASCULAR RISK FACTORS. CONCLUSIONS: YOGA HAS SHOWN PROMISE AS A USEFUL LIFESTYLE INTERVENTION THAT CAN BE INCORPORATED INTO CARDIOVASCULAR DISEASE MANAGEMENT ALGORITHMS. ALTHOUGH MANY INVESTIGATORS HAVE REPORTED THE CLINICAL BENEFITS OF YOGA IN REDUCING CARDIOVASCULAR EVENTS, MORBIDITY, AND MORTALITY, EVIDENCE SUPPORTING THESE CONCLUSIONS IS SOMEWHAT LIMITED, THEREBY EMPHASIZING THE NEED FOR LARGE, WELL-DESIGNED RANDOMIZED TRIALS THAT MINIMIZE BIAS AND METHODOLOGICAL DRAWBACKS.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
13 2416  23 YOGA AND MEDITATION IN CARDIOVASCULAR DISEASE. YOGA IS A HOLISTIC MIND-BODY INTERVENTION AIMED AT PHYSICAL, MENTAL, EMOTIONAL AND SPIRITUAL WELL BEING. SEVERAL STUDIES HAVE SHOWN THAT YOGA AND/OR MEDITATION CAN CONTROL RISK FACTORS FOR CARDIOVASCULAR DISEASE LIKE HYPERTENSION, TYPE II DIABETES AND INSULIN RESISTANCE, OBESITY, LIPID PROFILE, PSYCHOSOCIAL STRESS AND SMOKING. SOME RANDOMIZED STUDIES SUGGEST THAT YOGA/MEDITATION COULD RETARD OR EVEN REGRESS EARLY AND ADVANCED CORONARY ATHEROSCLEROSIS. A RECENT STUDY SUGGESTS THAT TRANSCENDENTAL MEDITATION MAY BE EXTREMELY USEFUL IN SECONDARY PREVENTION OF CORONARY HEART DISEASE AND MAY REDUCE CARDIOVASCULAR EVENTS BY 48% OVER A 5-YEAR PERIOD. ANOTHER SMALL STUDY SUGGESTS THAT YOGA MAY BE HELPFUL IN PREVENTION OF ATRIAL FIBRILLATION. HOWEVER, MOST STUDIES HAVE SEVERAL LIMITATIONS LIKE LACK OF ADEQUATE CONTROLS, SMALL SAMPLE SIZE, INCONSISTENCIES IN BASELINE AND DIFFERENT METHODOLOGIES, ETC. AND THEREFORE LARGE TRIALS WITH IMPROVED METHODOLOGIES ARE REQUIRED TO CONFIRM THESE FINDINGS. HOWEVER, IN VIEW OF THE EXISTING KNOWLEDGE AND YOGA BEING A COST-EFFECTIVE TECHNIQUE WITHOUT SIDE EFFECTS, IT APPEARS APPROPRIATE TO INCORPORATE YOGA/MEDITATION FOR PRIMARY AND SECONDARY PREVENTION OF CARDIOVASCULAR DISEASE.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
14 2196  26 THE EFFICACY AND SAFETY OF YOGA IN MANAGING HYPERTENSION. HYPERTENSION IS A MAJOR PUBLIC HEALTH PROBLEM AND ONE OF THE MOST IMPORTANT CAUSES OF PREMATURE MORBIDITY AND MORTALITY. YOGA IS A TRADITIONAL INDIAN PRACTICE THAT HAS BEEN ADAPTED FOR USE IN COMPLEMENTARY AND ALTERNATIVE MEDICINE AND MAINLY INCLUDES PHYSICAL POSTURES, BREATHING TECHNIQUES, AND MEDITATION. THE IMPACT OF YOGA AS A COMPLEMENTARY INTERVENTION FOR HYPERTENSION HAS BEEN INVESTIGATED IN A NUMBER OF RANDOMIZED CONTROLLED TRIALS; WITH AN OVERALL EFFECT OF ABOUT 10 MMHG REDUCTION IN SYSTOLIC AND ABOUT 8 MMHG REDUCTION IN DIASTOLIC BLOOD PRESSURE. YOGA SEEMS TO BE EFFECTIVE ONLY FOR HYPERTENSION BUT NOT FOR PREHYPERTENSION; AND ONLY AS AN ADJUNCT TO ANTIHYPERTENSIVE PHARMACOLOGICAL TREATMENT BUT NOT AS AN ALTERNATIVE THERAPY. BREATHING AND MEDITATION RATHER THAN PHYSICAL ACTIVITY SEEM TO BE THE ACTIVE PART OF YOGA INTERVENTIONS FOR HYPERTENSIVE PATIENTS. THESE PRACTICES CAN INCREASE PARASYMPATHIC ACTIVITY AND DECREASE SYMPATHETIC ACTIVITY, ARGUABLY MAINLY BY INCREASING GABA ACTIVITY; THUS COUNTERACTING EXCESS ACTIVITY OF THE SYMPATHETIC NERVOUS SYSTEM WHICH HAS BEEN ASSOCIATED WITH HYPERTENSION. ALTHOUGH YOGA HAS BEEN ASSOCIATED WITH SERIOUS ADVERSE EVENTS IN SINGLE CASE REPORTS, POPULATION-BASED SURVEYS AS WELL AS CLINICAL TRIALS INDICATE THAT YOGA IS A RELATIVELY SAFE INTERVENTION THAT IS NOT ASSOCIATED WITH MORE ADVERSE EVENTS THAN OTHER FORMS OF PHYSICAL ACTIVITY. YOGA CAN THUS BE CONSIDERED A SAFE AND EFFECTIVE INTERVENTION FOR MANAGING HYPERTENSION. GIVEN THE POSSIBLY BETTER RISK/BENEFIT RATIO, IT MAY BE ADVISABLE TO FOCUS ON YOGIC MEDITATION AND/OR BREATHING TECHNIQUES.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
15 1051  28 EFFECTS OF YOGA ON BRAIN WAVES AND STRUCTURAL ACTIVATION: A REVIEW. PREVIOUS RESEARCH HAS SHOWN THE VAST MENTAL AND PHYSICAL HEALTH BENEFITS ASSOCIATED WITH YOGA. YOGA PRACTICE CAN BE DIVIDED INTO SUBCATEGORIES THAT INCLUDE POSTURE-HOLDING EXERCISE (ASANA), BREATHING (PRANAYAMA, KRIYA), AND MEDITATION (SAHAJ) PRACTICE. STUDIES MEASURING MENTAL HEALTH OUTCOMES HAVE SHOWN DECREASES IN ANXIETY, AND INCREASES IN COGNITIVE PERFORMANCE AFTER YOGA INTERVENTIONS. SIMILAR STUDIES HAVE ALSO SHOWN COGNITIVE ADVANTAGES AMONGST YOGA PRACTITIONERS VERSUS NON-PRACTITIONERS. THE MENTAL HEALTH AND COGNITIVE BENEFITS OF YOGA ARE EVIDENT, BUT THE PHYSIOLOGICAL AND STRUCTURAL CHANGES IN THE BRAIN THAT LEAD TO THIS REMAIN A TOPIC THAT LACKS CONSENSUS. THEREFORE, THE PURPOSE OF THIS STUDY WAS TO EXAMINE AND REVIEW EXISTING LITERATURE ON THE EFFECTS OF YOGA ON BRAIN WAVES AND STRUCTURAL CHANGES AND ACTIVATION. AFTER A NARROWED SEARCH THROUGH A SET OF SPECIFIC INCLUSION AND EXCLUSION CRITERIA, 15 ARTICLES WERE USED IN THIS REVIEW. IT WAS CONCLUDED THAT BREATHING, MEDITATION, AND POSTURE-BASED YOGA INCREASED OVERALL BRAIN WAVE ACTIVITY. INCREASES IN GRAYGRAY MATTER ALONG WITH INCREASES IN AMYGDALA AND FRONTAL CORTEX ACTIVATION WERE EVIDENT AFTER A YOGA INTERVENTION. YOGA PRACTICE MAY BE AN EFFECTIVE ADJUNCTIVE TREATMENT FOR A CLINICAL AND HEALTHY AGING POPULATION. FURTHER RESEARCH CAN EXAMINE THE EFFECTS OF SPECIFIC BRANCHES OF YOGA ON A DESIGNATED CLINICAL POPULATION.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
16 1424  26 IMPROVEMENT IN PHYSIOLOGICAL AND PSYCHOLOGICAL PARAMETERS AFTER 6 MONTHS OF YOGA PRACTICE. YOGA IS BELIEVED TO HAVE BENEFICIAL EFFECTS ON COGNITION, ATTENUATION OF EMOTIONAL INTENSITY AND STRESS REDUCTION. PREVIOUS STUDIES WERE MAINLY PERFORMED ON EASTERN EXPERIENCED PRACTITIONERS OR UNHEALTHY SUBJECTS UNDERGOING CONCOMITANT CONVENTIONAL THERAPIES. FURTHER INVESTIGATION IS NEEDED ON THE EFFECTS OF YOGA PER SE, AS WELL AS ITS POSSIBLE PREVENTIVE BENEFITS ON HEALTHY SUBJECTS. WE INVESTIGATED THE EFFECTS OF YOGA ON MEMORY AND PSYCHOPHYSIOLOGICAL PARAMETERS RELATED TO STRESS, COMPARING YOGA PRACTICE AND CONVENTIONAL PHYSICAL EXERCISES IN HEALTHY MEN (PREVIOUSLY YOGA-NAIVE). MEMORY TESTS, SALIVARY CORTISOL LEVELS AND STRESS, ANXIETY, AND DEPRESSION INVENTORIES WERE ASSESSED BEFORE AND AFTER 6 MONTHS OF PRACTICE. YOGA PRACTITIONERS SHOWED IMPROVEMENT OF THE MEMORY PERFORMANCE, AS WELL AS IMPROVEMENTS IN PSYCHOPHYSIOLOGICAL PARAMETERS. THE PRESENT RESULTS SUGGEST THAT REGULAR YOGA PRACTICE CAN IMPROVE ASPECTS OF COGNITION AND QUALITY OF LIFE FOR HEALTHY INDIVIDUALS. AN INDIRECT INFLUENCE OF EMOTIONAL STATE ON COGNITIVE IMPROVEMENT PROMOTED BY YOGA PRACTICE CAN BE PROPOSED.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
17 2668  25 YOGA IN MAJOR DEPRESSIVE DISORDER: MOLECULAR MECHANISMS AND CLINICAL UTILITY. MAJOR DEPRESSIVE DISORDER (MDD) IS A MIND-BODY DISORDER. CELLULAR AGING HAS BEEN IMPLICATED IN THE PATHOGENESIS OF MDD WITH THE ALTERED MIND-BODY COMMUNICATION MARKERS LIKE STRESS RESPONSE, IMMUNE RESPONSE, NUTRITION SENSING, AND A RANGE OF OTHER REGULATORY FEEDBACK SYSTEMS. IN THIS AGE OF SUPER SPECIALIZATIONS, ONE SPECIFIC TARGET AND INTERVENTIONS (PREFERABLY A DRUG) ON IT ARE BEING RIGOROUSLY SOUGHT BY THE HEALTH CARE COMMUNITY AND INDUSTRY, BUT HAVE FAILED IN IT IN THE LAST FIFTY YEARS IN SPITE OF ADVANCES IN TECHNOLOGY. SINCE, DEPRESSION IS A COMPLEX DISORDER ASSOCIATED WITH INCREASED INCIDENCE OF OTHER COMPLEX DISORDERS, IT MUST BE TREATED BY AN INTEGRATED HOLISTIC APPROACH THAT CAN ADDRESS THE COMPLEXITY OF MDD. INTERVENTIONS TARGETING ACCELERATED BIOLOGICAL AGING TO INCREASE CELLULAR HEALTH IN WHOLE BODY HAVE POTENTIAL TO MANAGE COMPLEX CONDITIONS LIKE MDD AND ITS OVERLAPPING SYMPTOMS AND COMORBIDITIES. YOGA HAS THE POTENTIAL TO BE THE NEXUS BETWEEN, CLINICAL MANAGEMENT OF MDD AND OTHER LIFESTYLE DISEASES.	2021

THE FOCUS OF THIS REVIEW IS ON THE RESULTS OF HUMAN TRIALS ASSESSING THE ROLE OF YOGA IN IMPROVING THE SIGNS AND SYMPTOMS OF STRESS AND ANXIETY. OF 35 TRIALS ADDRESSING THE EFFECTS OF YOGA ON ANXIETY AND STRESS, 25 NOTED A SIGNIFICANT DECREASE IN STRESS AND/OR ANXIETY SYMPTOMS WHEN A YOGA REGIMEN WAS IMPLEMENTED; HOWEVER, MANY OF THE STUDIES WERE ALSO HINDERED BY LIMITATIONS, SUCH AS SMALL STUDY POPULATIONS, LACK OF RANDOMIZATION, AND LACK OF A CONTROL GROUP. FOURTEEN OF THE 35 STUDIES REPORTED BIOCHEMICAL AND PHYSIOLOGICAL MARKERS OF STRESS AND ANXIETY, BUT YIELDED INCONSISTENT SUPPORT OF YOGA FOR RELIEF OF STRESS AND ANXIETY. EVALUATION OF THE CURRENT PRIMARY LITERATURE IS SUGGESTIVE OF BENEFITS OF YOGA IN RELIEVING STRESS AND ANXIETY, BUT FURTHER INVESTIGATION INTO THIS RELATIONSHIP USING LARGE, WELL-DEFINED POPULATIONS, ADEQUATE CONTROLS, RANDOMIZATION AND LONG DURATION SHOULD BE EXPLORED BEFORE RECOMMENDING YOGA AS A TREATMENT OPTION.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
19  576  36 DEPRESSION AND ANXIETY DISORDERS: BENEFITS OF EXERCISE, YOGA, AND MEDITATION. MANY PEOPLE WITH DEPRESSION OR ANXIETY TURN TO NONPHARMACOLOGIC AND NONCONVENTIONAL INTERVENTIONS, INCLUDING EXERCISE, YOGA, MEDITATION, TAI CHI, OR QI GONG. META-ANALYSES AND SYSTEMATIC REVIEWS HAVE SHOWN THAT THESE INTERVENTIONS CAN IMPROVE SYMPTOMS OF DEPRESSION AND ANXIETY DISORDERS. AS AN ADJUNCTIVE TREATMENT, EXERCISE SEEMS MOST HELPFUL FOR TREATMENT-RESISTANT DEPRESSION, UNIPOLAR DEPRESSION, AND POSTTRAUMATIC STRESS DISORDER. YOGA AS MONOTHERAPY OR ADJUNCTIVE THERAPY SHOWS POSITIVE EFFECTS, PARTICULARLY FOR DEPRESSION. AS AN ADJUNCTIVE THERAPY, IT FACILITATES TREATMENT OF ANXIETY DISORDERS, PARTICULARLY PANIC DISORDER. TAI CHI AND QI GONG MAY BE HELPFUL AS ADJUNCTIVE THERAPIES FOR DEPRESSION, BUT EFFECTS ARE INCONSISTENT. AS MONOTHERAPY OR AN ADJUNCTIVE THERAPY, MINDFULNESS-BASED MEDITATION HAS POSITIVE EFFECTS ON DEPRESSION, AND ITS EFFECTS CAN LAST FOR SIX MONTHS OR MORE. ALTHOUGH POSITIVE FINDINGS ARE LESS COMMON IN PEOPLE WITH ANXIETY DISORDERS, THE EVIDENCE SUPPORTS ADJUNCTIVE USE. THERE ARE NO APPARENT NEGATIVE EFFECTS OF MINDFULNESS-BASED INTERVENTIONS, AND THEIR GENERAL HEALTH BENEFITS JUSTIFY THEIR USE AS ADJUNCTIVE THERAPY FOR PATIENTS WITH DEPRESSION AND ANXIETY DISORDERS.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
20 1811  33 PROFILE OF MOOD STATES AND STRESS-RELATED BIOCHEMICAL INDICES IN LONG-TERM YOGA PRACTITIONERS. BACKGROUND: PREVIOUS STUDIES HAVE SHOWN THE SHORT-TERM OR INTERMEDIATE-TERM PRACTICE OF YOGA TO BE USEFUL FOR AMELIORATING SEVERAL MENTAL DISORDERS AND PSYCHOSOMATIC DISORDERS. HOWEVER, LITTLE IS KNOWN ABOUT THE LONG-TERM INFLUENCES OF YOGA ON THE MENTAL STATE OR STRESS-RELATED BIOCHEMICAL INDICES. IF YOGA TRAINING HAS A STRESS-REDUCTION EFFECT AND ALSO IMPROVES AN INDIVIDUAL'S MENTAL STATES FOR A LONG TIME, LONG-TERM YOGA PRACTITIONERS MAY HAVE A BETTER MENTAL STATE AND LOWER STRESS-RELATED BIOCHEMICAL INDICES IN COMPARISON TO NON-EXPERIENCED PARTICIPANTS. THIS STUDY SIMULTANEOUSLY EXAMINED THE DIFFERENCES IN MENTAL STATES AND URINARY STRESS-RELATED BIOCHEMICAL INDICES BETWEEN LONG-TERM YOGA PRACTITIONERS AND NON-EXPERIENCED PARTICIPANTS. METHODS: THE PARTICIPANTS WERE 38 HEALTHY FEMALES WITH MORE THAN 2 YEARS OF EXPERIENCE WITH YOGA (LONG-TERM YOGA GROUP) AND 37 AGE-MATCHED HEALTHY FEMALES WHO HAD NOT PARTICIPATED IN YOGA (CONTROL GROUP). THEIR MENTAL STATES WERE ASSESSED USING THE PROFILE OF MOOD STATES (POMS) QUESTIONNAIRE. THE LEVEL OF CORTISOL, 8-HYDROXYDEOXYGUANOSINE (8-OHDG) AND BIOPYRRIN IN URINE WERE USED AS STRESS-RELATED BIOCHEMICAL INDICES. RESULTS: THE AVERAGE SELF-RATED MENTAL DISTURBANCE, TENSION-ANXIETY, ANGER-HOSTILITY, AND FATIGUE SCORES OF THE LONG-TERM YOGA GROUP WERE LOWER THAN THOSE OF THE CONTROL GROUP. THERE WAS A TREND TOWARD A HIGHER VIGOR SCORE IN THE LONG-TERM YOGA GROUP THAN THAT IN THE CONTROL GROUP. THERE WERE NO SIGNIFICANT DIFFERENCES IN THE SCORES FOR DEPRESSION AND CONFUSION IN THE POMS BETWEEN THE TWO GROUPS. THE URINE 8-OHDG CONCENTRATION SHOWED A TREND TOWARD TO BEING LOWER IN THE LONG-TERM YOGA GROUP IN COMPARISON TO THE CONTROL GROUP. THERE WERE NO SIGNIFICANT DIFFERENCES IN THE LEVELS OF URINE BIOPYRRIN OR CORTISOL. CONCLUSIONS: THE PRESENT FINDINGS SUGGEST THAT LONG-TERM YOGA TRAINING CAN REDUCE THE SCORES RELATED TO MENTAL HEALTH INDICATORS SUCH AS SELF-RATED ANXIETY, ANGER, AND FATIGUE.	2011
