Intracranial arterial stenosis in Caucasians versus Asians

Intracranial arterial stenosis (ICAS) is the leading cause of stroke worldwide. Separate studies have investigated the prevalence of ICAS in Caucasians and Asians, but none of them directly compared these two ethnic groups. This current study was the first to compare the prevalence and risk factors of patients with transient ischaemic attack (TIA) and minor stroke in Caucasian and Asian populations.  Result showed that Chinese patients were more susceptible to ICAS than Caucasians, with an earlier onset age (possibly 20 years earlier) and a higher prevalence (almost doubled).
