Lacunar Infarct
Signs and Symptoms
The deep brain structures that can be injured by a lacunar infarct help to coordinate complicated movements or help to relay information from brainstem to the cerebral cortex. In the case of a lacunar infarct, brain cells that constitute a relatively small area are injured or destroyed from a lack of oxygen. Lacunae are small cavities that remain after the necrotic tissue is cleared away. Though this type of infarct involves only a small area of the brain, it still may cause significant disability.
Symptoms can include (Agranoff, 2011):
