—Patients with extensive ischemic cortical strokes in the middle cerebral artery territory usually experience aphasia when the dominant cerebral hemisphere is lesioned, and dysarthria when the nondominant hemisphere is involved.¹ Lacunar infarctions are small, deep ischemic strokes (with an average lesional diameter of less than 20 mm).^2,3 In such cases, aphasia is unusual. Some patients with either right or left hemispheric lacunar infarctions present with dysarthria, but little is known about that symptom.⁴

To study the location of the lesions responsible for dysarthria in lacunar infarctions and the associated neurologic symptomatology, we performed a clinical examination and computed tomography of the head in 227 consecutive patients with lacunar infarctions (125 pure motor hemiparesis; 42 pure sensory stroke; 34 sensorimotor stroke; 7 ataxic hemiparesis, 4 dysarthria-clumsy hand; and 15 atypical lacunar syndromes).
