Signs, symptoms and: Effects all depend on where in the brain the infarction occurs. Lacunar infarctions can be seen on mri, often a very small area of atrophy.

Lacunar Stroke: Lacunar stroke is a type of stroke that results from occlusion of one of the penetrating arteries that provides blood to the brain's deep structures. It is estimated that lacunar infarcts account for 25% of all ischemic strokes, with an annual incidence of approximately 15 per 100, 000 people. They may be more frequent in men and in people of african, mexican, and hong kong chinese descent.
