title: Beneficial Effects of Yogasanas and Pranayama in limiting the Cognitive decline in Type 2 Diabetes.
abstract: BACKGROUND
  Out of many complications that were observed in type 2 diabetes, cognitive impairment is the most neglected.
  
  
  OBJECTIVE
  The aim of the present study is to assess the cognitive decline in type 2 diabetes and to observe the role of yogasanas and pranayama in ameliorating the cognitive decline.
  
  
  METHODS
  Sixty eight type 2 diabetic subjects were recruited in the study, 34 of them did specific yogasanas and pranayama (test group) for six months and the remaining age and sex matched 34 subjects were recruited as (control group) who were not on any specific exercise regimen. Glycaemic index was estimated by measuring the glycosylated haemoglobin (HbA1c) concentration with Bio-Rad apparatus and cognition was assessed by using Addenbrook's Cognitive Examination-Revised (ACE-R), which is a neuropsychological battery.
  
  
  METHODS
  Data was analysed with unpaired student t test. P value<0.05 is considered as statistically significant. Validity was assessed by receiver operating characteristics.
  
  
  RESULTS
  Analysis of data indicated more cognitive scores in the test group when compared with the control group. In test group six months practice of yogasanas and pranayama has also significantly brought down the high glycaemic values which were observed in the control group.
  
  
  CONCLUSIONS
  These findings allow the study to conclude that regular practice of yogasanas and pranayama has a beneficial effect on cognitive performance in type 2 diabetic subjects by stabilizing blood glucose.
