“Background & objectives: Electrophysiological evidence of delayed cognition as measured by P300, an evoked potential is observed in Diabetes 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 diabetic patients.”
“Results: Statistically significant improvement in the latency and the amplitude of N200, P300 was observed in the yoga group as compared to the control group.”
“Interpretation & conclusions: Our data suggest that yoga has a beneficial effect on P300 and thus can be incorporated along with the conventional medical therapy for improving cognitive brain functions in diabetes.”
The study also found a significant reduction in hyperglycemia and a decrease in the drugs usage when yoga therapy was incorporated. The study lists the simple asanas and pranayamas that were used in the study.
We suggest reading the whole study.
