AbstractAim: The aim of the present study was to correlate duration of disease with attention, executive function andvisual reaction time in type 2 diabetes patients and to correlate HbA1c with attention, executive function andvisual reaction time in type 2 diabetes patients.Methods: This was a retrospective study done on 100 type 2 diabetes mellitus subjects of either sex under the agegroup of 40-60 years in the Department of Physiology, Jawaharlal Nehru Medical College, Bhagalpur, Bihar,India . The subjects who are able to understand English were enrolled for the study. Written informed consentwas taken and each subject was explained about the whole procedure and objective of the study.Results: The mean age and BMI of the patients were 58.06±4.48 and 24.56+1.94 respectively. There were 55male and 45 females in the present study. Duration of disease was positively correlated (r=0.34) with score ofDigit Vigilance Test and p value statistically significant (0.016). A positive correlation (r=0.24) was also seenwith Visual Reaction time and p value statistically significant (0.046). Stroop test score also shows a positivecorrelation (r=0.16) but without any statistical significance. HbA1c was positively correlated(r=0.56) with thescore of Digit Vigilance Test and p value statistically significant (0.01). A positive correlation (r=0.36) was alsoseen with Visual Reaction time and p value statistically significant (0.01). Stroop test score also shows a positivecorrelation (r=0.16) but without any statistical significance.Conclusion: With increase in duration of the disease and poor glycemic control, sustained attention and executivefunctions are declining. Also there is an increase in visual reaction time. Diabetes is a disease which requiresproper self-care and monitoring. The decline in cognitive functions can affect their activities like glucosemonitoring, medications or insulin injection patterns, diet and exercise timing.
