Category specific naming impairment was described mainly after cortical lesions. It is thought to result from a lesion in a specific network, reflecting the organization of our semantic knowledge. The deficit usually involves multiple semantic categories whose profile of naming deficit generally
Observation of a patient suffering from a double softening of the brain (inner side of right temporal lobe, left occipital lobe). Clinically, Korsakoff's syndrome, right quadranopsia, pure alexia, tactile and visual agnosia concerning objects, colors and faces. Relative integrity of elementary
This study describes the case of CH, a 68-year-old left-handed woman who suffered a right temporo-parieto-occipital infarct in the territory of the middle cerebral artery and who exhibits severe proper name anomia. During the acute stage, CH was diagnosed with severe amnestic aphasia (Aachen Aphasia
We report a patient who had a callosal infarct, showed by Computer Tomography and Magnetic Resonance Imaging, without injury to the adjacent hemispheres. Angiography revealed an occlusion of both internal carotid arteries. Besides interhemispheric disconnection with unilateral left agraphia, left
A 70 year old retired van driver, with a diagnosis of multi-infarct dementia, showed features associated with transcortical sensory aphasia, with excellent repetition, a severe anomia, poor semantic comprehension and fluent speech. He was able to spell orally words which he did not understand, as
We report a right-handed 67-year-old woman with an infarction in the left posterior cerebral artery territory presenting amnesic syndrome, right homonymous hemianopsia, pure alexia, color anomia, and defective route finding. The patient often walked in wrong directions out of her hospital room as
We examined a 70-year-old woman who became aphasic after a left thalamic infarction. Computed tomographic scan showed injury that was largely limited to the ventral anterior and rostral ventral lateral thalamic nuclei. Speech was characterized by reduced voice volume, impaired auditory and reading
The authors present three cases of hospitalized patients on a geriatric psychiatry floor who were found to have previously undiagnosed occipital lobe infarctions associated with visual manifestations. The manifestations discussed are visual field defects, visual hallucinations, and color anomia. The
Behavioral disorders were a prominent clinical feature after the surgical treatment of an anterior communicating artery aneurysm rupture in a 44-year-old man. Callosal apraxia was associated with an alien hand. The latter remained 1 year after surgery while diagonistic apraxia disappeared after 3
A left-handed Japanese man is reported who presented right-hand agraphia and tactile anomia following callosal infarction. Magnetic resonance imaging revealed an ischemic lesion extending from the posterior half of the trunk to the splenium of the corpus callosum. In his right handwriting, the
A partial syndrome of hemisphere disconnection was observed in a 63 year-old woman, following an anterior and middle corpus callosum infarct on MRI. Notably, we found left ideomotor apraxia, diagonistic apraxia, left-year extinction on dichotic listening, but no left-hand anomia nor left visual
A 49-year old right-handed taxi-driver experienced right upper limb weakness and global aphasia following internal carotid artery occlusion. Five months later, aphasia and hemiparesis had resolved but he complained of difficulties in his daily activities, termed "inner conflict". Specific testings
Speech and language functions were assessed in 18 patients with multi-infarct dementia (MID) and 14 with dementia of the Alzheimer type (DAT). The age range and dementia severity of the two groups were comparable. We used a speech and language battery assessing 37 elements of verbal output to
Following a cerebral vascular accident, a patient showed a classical disconnection syndrome: left-hand tactile anomia, apraxia and dysgraphia and right-hand constructional apraxia. What made the case unusual was the presence of hand asymmetry in the performance of some matching-to-sample tasks
