Abstract

Summary of Review—

A high frequency of lacunar strokes is a familiar pattern among South Asians, which suggests a greater prevalence of small-vessel disease in South Asians. This may be a consequence of abnormal metabolic and glycemic processes. In addition, stroke mortality among South Asians appears to be explained by glycemic status, which is an independent predictor of long-term stroke mortality. Within India, there is a perceptible rural–urban gradient in stroke prevalence, underlying the dangers of the rapid transition in socioeconomic circumstances seen across the Indian subcontinent.

Conclusions—

This review emphasizes the importance of further research into ischemic stroke for South Asians given their higher cardiovascular disease burden and necessity for targeted healthcare approaches.
