Stroke Risk and Vascular Dementia in South Asians

Abstract

Purpose of review: South Asians (SA) are at a higher risk for stroke and vascular dementia due to the disproportionate burden of diabetes, hypertension, and dyslipidemia. This review summarizes the rationale for screening, early detection, and aggressive control of metabolic factors, and critically examines the published literature on primary and secondary stroke prevention.

Recent findings: South Asians have a higher prevalence of diabetes than non-SA. SA with diabetes are at a higher risk of recurrent ischemic stroke and have a higher incidence of stroke-related dementia compared to non-South Asians. South Asians are one of the fastest-growing ethnic groups worldwide with an unusually increased risk of heart disease and stroke. An accurate assessment of those at risk of stroke and cognitive impairment is urgently needed to plan preventive strategies.
