Subcortical anarthria: a case report.

A 56-year-old right-handed male with a history of hypertension and diabetes presented two episodes of stroke: The first affected territory was the left anterior coroidal artery (capsular and paracapsular infarcts at the level of the genu and posterior arm of the internal capsule) and the second was the right thalamus, due to a hematoma. Following the first stroke, the patient developed severe dysarthria and after the second stroke remained anarthric. The pathophysiology of the disorder is discussed, and the role of the left and right thalamus as far as speech is concerned is reviewed.

Akinetic mutism: a report of three cases.

OBJECTIVES: To report 3 new cases of akinetic mutism, a clinical syndrome defined by silent immobility with preserved visual alertness not accountable by lesion of the areas and/or effector pathways of speech and voluntary movements. MATERIAL AND METHODS: Anatomopathological studies were performed in Cases 1 and 2; clinical follow-up, EEG, angiography and CT scans in Case 3. RESULTS: Case 1: Bipallidal necrosis; Case 2: Left pallidal necrosis with right frontoparietal cortico-subcortical infarction; Case 3: Striato-capsular infarction on the left side, involving the caudate nucleus and the anterior arm of the internal capsule, together with obstructive hydrocephalus. CONCLUSION: The roles of both globus pallidus and prefrontostriatal circuits in the onset of voluntary movements are discussed.
