Classic lacunar stroke syndromes

Lacunar syndrome	Location	Clinical findings	Positive predictive value
Pure motor hemiparesis	Internal capsule, corona radiata, basal pons, medial medulla	Unilateral paralysis of face, arm and leg, no sensory signs, dysarthria and dysphagia may be present	52-85 percent
Pure sensory syndrome	Thalamus, pontine tegmentum, corona radiata	Unilateral numbness of face, arm and leg without motor deficit	95-100 percent
Ataxic hemiparesis	Internal capsule-corona radiata, basal pons, thalamus	Unilateral weakness and limb ataxia	59-95 percent
Sensorimotor syndrome	Thalamocapsular, maybe basal pons or lateral medulla	Hemiparesis or hemiplegia of face, arm and leg with ipsilateral sensory impairment	51-87 percent
Dysarthria-clumsy hand syndrome	Basal pons, internal capsule, corona radiata	Unilateral facial weakness, dysarthria and dysphagia, with mild hand weakness and clumsiness	About 96 percent
