Stroke Symptoms With Absence of Recognized Stroke Are Associated With Cognitive Impairment and Depressive Symptoms in Older Adults With Diabetes.

Abstract

Self-reported stroke symptoms may represent unrecognized cerebrovascular events leading to poorer cognitive and mental health. We examined relationships between stroke symptoms, cognitive impairment, and depressive symptoms in a high-risk sample: 247 adults aged ≥65 with diabetes. Stroke symptoms were assessed using the Questionnaire for Verifying Stroke-free Status, cognitive impairment was measured with the modified Telephone Interview for Cognitive Status, and depressive symptoms were measured using the 15-item Geriatric Depression Scale. In 206 participants without history of stroke/transient ischemic attack, 27.7% reported stroke symptoms, with sudden loss of comprehension most frequently reported (11.7%). Having >1 versus 0 stroke symptoms was associated with greater odds of cognitive impairment (odds ratio = 3.04, 95% confidence interval 1.15-8.05) and more depressive symptoms (b= 2.60,P< .001) while controlling for age, race, gender, education, diabetes duration, diabetes severity, and cardiovascular comorbidities. Better recognition and treatment of cerebrovascular problems in older adults with diabetes may lead to improved cognition and mental health.
