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 lef
t 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 pati
ent developed severe dysarthria and after the second stroke remained anarth
ric. The pathophysiology of the disorder is discussed, and the role of the
left and right thalamus as far as speech is concerned is reviewed. (C) 2001
