Diabetes type 2, hypertension and cognitive dysfunction in middle age women

Type 2 diabetes mellitus and hypertension are two widely spread diseases among the adults that are known to be risk factors for vascular disease. They are highly related such that comorbidity is common. The purpose of the present study was to investigate the comorbid effects of type 2 diabetes and hypertension on cognitive decline. One hundred and thirteen patients with type 2 diabetes (women, age 56 +/- 7.4 years, diabetes duration 8 +/- 6.7 years, hypertension duration 13.4 +/- 7.7 years) were assessed for cognitive impairment (CI) in comparison with 27 diabetes patients without hypertension (women, age 53 +/- 7.45 years, diabetes duration 4.4 +/- 5.6 years), all non-demented at baseline. Patients were screened for cognitive dysfunction with the Mini Mental State Examination (MMSE), a clock-drawing test (CDT) and Frontal Assessment Battery (FAB). We assessed history of DM and hypertension by interview. 87% of women with diabetes and hypertension and 70% of normotensive diabetic patients had cognitive impairment (p = 0.0282), of mild and subtle degree. The frequency of alterations in the FAB was higher in subjects with diabetes and hypertension (48%) compared to normotensive diabetic patients (26%) p=0.0402. Our results show that people with diabetes type 2 and hypertension demonstrate greater cognitive changes as compared to normotensive diabetic patients. (C) 2010 Elsevier B.V. All rights reserved.
