Abstract

The objective of this article is to study the impact of Hindustani ragas on the cognitive functions of the right and left cerebral hemispheres, especially of the parieto-occipital lobe, in patients with cerebrovascular accident and diffuse head injury. A randomized control trial was conducted. The case group consisted of 30 patients who received both medicine and ragas, while the control group of 30 patients received only medicine. A total of 10 Hindustani ragas were taken up, and 4 follow-ups with baseline were conducted. Nahor-Benson test, a subtest of the Post Graduate Institute–Battery for Brain Dysfunction, was used at different time intervals. Univariate repeated measures analysis revealed significant differences between the 2 groups at different time intervals, confirming that listening to ragas improved visual perceptual acuity, spatial orientation, and the cognitive functions involving both right and left hemispheres of the case group patients.
