The lasting effects of ministrokes may contribute to dementia

Investigators report preclinical research showing that microinfarcts induce prolonged dysfunction in brain areas estimated to be 12-times larger than the visible injury site. Data from c-Fos assays and in vivo hemodynamic imaging reveal how individually miniscule microinfarcts might collectively contribute to broader brain dysfunction in patients with vascular cognitive impairment and dementia….
