Microbleed After Ischemic Attack Predicts Recurrent Stroke Risk

White matter hypertensities were also a major predictor of recurrent stroke risk.

The presence of cerebral microbleeds on brain imaging was found to be an independent predictor of early recurrent stroke following transient ischemic attack (TIA) in a prospective study of outcomes among patients treated at comprehensive stroke centers in South Korea.

Cerebral microbleeds conveyed a more than threefold increased risk for having a stroke within 90 days of the transient ischemic event, according to a Korean registry analysis.

The 5% overall rate of stroke recurrence during this 90-day window was lower than that seen in many previous studies, suggesting that optimal, immediate treatment lowers the risk of early stroke recurrence in this group.
