Question

The patient with transient cerebral ischemia: a golden opportunity for stroke prevention

Answer 1

TRANSIENT ISCHEMIC ATTACK (TIA) provides a golden opportunity for stroke prevention. TIA should be treated as a medical emergency with prompt investigations to determine the mechanism of ischemia and subsequent preventivetherapy. The risk of stroke after TIA is estimated to be 10%–20% in the first 90 days.

Lacunar Infarcts. Lacunar strokes are small infarcts in deep non-cortical white matter or the brainstem that result from the occlusion of penetrating branches of cerebral arteries. The term “lacune” refers to the crescent- or moon-shaped tiny stroke that results from occlusion of these vessels.
