agnosia/infarction

A 68-year-old man was admitted to our hospital for rehabilitation of topographical disorientation. Brain magnetic resonance imaging revealed infarction in the right medial side of the occipital lobe. On neuropsychological testing, he scored low for the visual information-processing task; however,

BACKGROUND Anosognosia for hemiplegia (AHP) is unawareness of unilateral motor deficit. This syndrome usually is reported in association with large lesions of the nondominant frontal and parietal lobes, the perithalamic lesions or their connexions with cortical or subcortical structures. Little is

We report a 74-year-old right-handed man with visual agnosia for picture due to right occipital lobe infarction. The patient had a remarkable impairment in visual recognition for standardized pictures made by Snodgrass and Vanderwart, in addition to left hemianopsia, left visuospatial neglect, and

We reported a patient who showed agnosia for streets and homes unaccompanied by prosopagnosia of familiar faces following infarction in the right occipital lobe. A 70-years-old right-handed man admitted to our department because of sudden development of visual impairment. He had left hemianopsia,

After a cerebral infarction, some patients acutely demonstrate contralateral hemiplegia, or aphasia. Those are the obvious symptoms of a cerebral infarction. However, less visible but burdensome consequences may go unnoticed without closer investigation. The importance of a thorough clinical

The authors report a 63-year-old man with a history of brief isolated manic episodes who became persistently hypomanic after a small right thalamic infarct. Detailed behavioral and neuropsychologic assessment were performed 18 months after the stroke and revealed a prosopoaffective agnosia as the

We report a patient with anosognosia for hemiplegia associated with a right pontine infarction. A 51-year-old woman with histories of hypertension and diabetes mellitus was admitted because of weakness of her left upper and lower extremities. On neurologic examination, she was alert and oriented

The objective of the study is to evaluate if the rupture of an aneurysm located on the middle cerebral artery (MCA) results in disorders of music recognition. To this aim, 20 patients having undergone brain surgery for the clipping of a unilateral left (LBS), right (RBS) or bilateral (BBS)

The authors describe a patient who experienced the sudden occurrence of hemicorea-hemiballism on the left side of the body and the contemporary agnosia of it. An unenhanced CT-scan disclosed an ischemic lesion involving the head of the caudate nucleus and of the anterior limb of the internal capsule

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

BACKGROUND To evaluate systematically the cognitive deficits following posterior cerebral artery (PCA) strokes, especially agnosic visual disorders, and to study anatomical-clinical correlations. RESULTS We investigated 31 patients at the chronic stage (mean duration of 29.1 months post infarct)

The dextrocerebral stroke is often underestimated as a result of its deficits--in contrary to the left cerebral stroke with the aphasia--because the patient's neglect of the plegic side is transferred to the therapist. A key to understanding this is the hypothesis that the anosognosia results in a

Anosognosia for hemiplegia (AHP) is known to be associated with lesions to the motor system combined with varying lesions to the right insula, premotor cortex, parietal lobe or hippocampus. Due to this widespread cortical lesion distribution, AHP can be understood best as a network disorder. We used

Verbal auditory agnosia are rare in clinical practice. Clinically, it characterized by impairment of comprehension and repetition of speech but reading, writing, and spontaneous speech are preserved. So it is distinguished from generalized auditory agnosia by the preserved ability to recognize non

A number of higher visual deficits accompanied by severe retrograde autobiographical memory loss following bilateral medial occipital infarctions are described in case M.H. Assessment of M.H.'s visual object agnosia and prospagnosia suggested that he was unable to integrate the elements of a percept
