In this pooled patient data analysis of >20k patients with strokes, women had lower prevalence of cerebral microbleeds and lacunes, but more severe white matter hyperintensities, suggesting sex-related differences in cerebral small vessel disease. ja.ma/3BUqTkp

For years, many of us used traumatic microbleeds on MRI to prognosticate in the ICU for pts w/ severe TBI. We assumed microbleed = axonal injury. This assumption was incorrect: medrxiv.org/content/10.110…
