A Study of Executive Functioning in Type 2 Diabetes Mellitus Patients in Relation with the Duration of Diabetes
Abstract
Background: Type 2 diabetes mellitus increases the incidence of cognitive impairment by two to three fold when compared to non-diabetics. This causes impairment in the Activities of Daily Living (ADL) in the patients which in turn leads to immeasureable caregiver burden and increase in healthcare expenditure. Effective functioning in ADL depends upon the intact executive functions controlled by the Frontal lobe. Objective: To measure the executive functioning in type 2 diabetes patients using Frontal Assessment Battery (FAB). Materials and Methods: Fifty six Type 2 diabetes mellitus patients in the age group of 30-50 yrs in both genders were screened for dementia using Mini Mental Scale Examination (MMSE). Then their executive functions were assessed using FAB under six domains- conceptualization, mental flexibility, programming, sensitivity to interference, inhibitory control and environmental autonomy. Results: The total scores of MMSE, FAB and the individual scores of six domains of
FAB were correlated with duration of diabetes using Pearson rank correlation and a statistically significant linear correlation was obtained in the negative direction for all the variables. Conclusion: Type 2 diabetes is associated with poor executive functioning and the same deteriorates as the duration of disease increases.
