Hatha Yoga effects on Alzheimer patients (AP)

Abstract This study assessed the effect of a Hatha yoga program in 20 men and 41 women diagnosed with Alzheimer's Disease (AD), who showed mild (36%) and moderate (64 %) global cognitive decline and whose average age was 76,9 years old (SD=11,7). The design was quasi-experimental of repeated measures (pre, post and follow-up). The instruments applied were: Alzheimer's Disease Related Quality of Life Scale (ADRQL); Questionnaire of Quality of Life (QQL), Geriatric Depression Scale (YESAVAGE); Mini Mental State Examination (MMSE); memory and processing speed sub-scales of WAIS III test, Trail Making Test (TMT-A); Lawton and Brody Test; and Barthel Test. The yoga program consisted of 32 one hour sessions twice a week Data analysis was conducted using 35 patients who participated throughout the whole study. The post-treatment mean showed a positive improvement tendency in quality of life and attention. However, during the follow-up, these variables mean value was equal to, or even lower, than the one established in the pre-treatment. The repeated measures ANOVA results showed that no significant change occurred between measurements. The content analysis of eight focus groups suggests that, from the perspective of patients and caregivers, positive changes were observed in patients' mood, attention, episodic and procedural memory, and functionality. More studies are necessary with a higher number of patients and sessions per week, as well as a control group, whose function would be to increase validity of the results obtained.
