Abstract Language disturbances were studied in 40 patients with well-demarcated vascular
lesions of the speech-dominant hemisphere. Computerized cranial tomography was used …

Forty-five patients with unilateral demarcated vascular lesions in the basal ganglia, the
thalamus and the deep white matter were investigated with an “aphasia battery.” Patients …

Seven aphasic patients with circumscribed left basal ganglia infarctions were investigated
within the first 15 days after their strokes. Five showed transcortical motor aphasia initially …

Describes the case of a 25-yr-old female patient in whom intervention in the left thalamus,
aimed at removing an aneurysm, resulted in a clear derangement of speech. Through a …

• Two cases with expressive speech disorders were studied neuropsychologically and
neurologically; anatomical and histopathological examinations were performed in both …

Language was studied in four patients with bilateral cerebral infarctions. Bilateral destruction
of the third frontal gyri did not necessarily produce the severely limited language output …

Recent evidence suggests that subcortical lesions can give rise to aphasic symptoms. Two
subcortical structures thought to participate in the pathogenesis of aphasia are the basal …

Until modern times the study of the cerebral organization of language coincided largely with
the study of aphasia. Adults with focal cerebral lesions, usually strokes (secondary to …

The language abilities of 14 Ss (aged 40–91 yrs) with chronic nonthalamic subcortical (NS)
lesions following stroke were assessed using a test battery probing a broad range of …

• Atypical aphasia syndromes were associated with circumscribed nonhemorrhagic
infarctions of the anterior limb of the internal capsule and of the striatum, in the dominant …
