Effectiveness of Music Therapy on Focused Attention, Working Memory and Stress in Type 2 Diabetes: An Exploratory Study.

Cognitive deficits are reported in diabetes mellitus type 2 (DM2). Previous research has shown that music-based intervention can not only reduce hyperglycemia but also target cognitive functions as well as stress. The aim of this exploratory study was to understand the effect of active participation in music therapy (MT) on the cognitive deficits of DM2 patients. MT of twenty sessions was carried out with three participants with DM2. Serum cortisol, perceived stress, Color Trail Test (1 and 2), and verbal n-back (1 and 2) tests were used to measure the outcomes. Feedback was taken for the subjective ratings and satisfaction of the participants. Stress and cortisol reduced and focused attention and working memory improved in varying degrees. Subjectively, participants reported having benefitted from the intervention. This is the first attempt to investigate the effect of music-based intervention on cognitive function in DM2 patients using case study approach.
