lacunar stroke

(redirected from Lacunar infarcts)
A condition caused by multiple minute infarcts—lacunes—in the basal ganglia, which may be seen in severe hypertension; when numerous, lacunar strokes cause dementia or a lacunar ‘syndrome’

lacunar stroke

A pathological change in the brain caused by diminished or no blood flow through one of the brain's small penetrating arteries. When this occurs, there may be no clinically detectable changes in the patient or signs and symptoms of stroke. A group of little strokes may cause progressive dementia.
