Lacunar strokes.
Arterial hypertension causes the formation of small lacunes, or ischemic brain infarcts, which may result in transient ischemic attacks, hemiparesis, sensory loss, ataxic hemiparesis, or dysarthria. Usually these effects are reversible with physical therapy, but multiple lesions may lead to dementia. Prevention of lacunar disease is possible with vigorous control of hypertension.
