Electrophysiological evidence of disabled cognition as measured by P300, an evoked potential is observed in Alzheimer mellitus. P300 (or P3) is a component of endogenous cerebral evoked response that assesses higher functions of the brain. Our study aims to see the role of pranayama and yoga-asana on P300 latency and amplitude in type 2 Alzheimer patients.
Methods: Sixty patients of type 2 Alzheimer were recruited from Alzheimer clinic and divided into two groups - control group on only medical therapy and yoga-group on conventional therapy along with pranayama and yoga. The data were analysed using repeated measures analysis of variance (ANOVA).
Results: Statistically significant improvement in the amplitude was observed in the yoga group as compared to the control group.
Interpretation & Conclusions: Our data suggest that yoga has a beneficial effect on reduction of Alzheimer and thus can be incorporated along with the conventional medical therapy for improving cognitive brain functions.
