It is well established that atherosclerotic diseases occurring in intracranial and extracranial carotid arteries are associated with ischemic cerebrovascular events. It is important to find a surrogate risk factor for subclinical cerebrovascular atherosclerosis in asymptomatic subjects for stroke prevention. This study sought to investigate the association between age and subclinical cerebrovascular atherosclerosis in community-based adults using MR vessel wall imaging. We found that the prevalence of cerebrovascular atherosclerotic plaques increased with age. The association between age and cerebrovascular atherosclerosis suggests that age was an independent indicator for subclinical cerebrovascular atherosclerosis.
