We studied recovery of function in 41 patients with right hemisphere stroke. Recovery was rapid for left neglect, prosopagnosia, anosognosia, and unilateral spatial neglect on drawing (USN). Recovery was slower for h mianopia, hemiparesis, motor impersistence, and extinction. Rates of recovery were
Purpose. To study and follow-up achromatopsia, prosopagnosia, and topographagnosia in a patient who suffered a bilateral stroke of the posterior cerebral arteries. Methods. Ophthalmological, neuropsychological and neuroradiological examinations were conducted over a span of 3 years to assess the

A 68-year-old woman with schizophrenia after a cerebrovascular accident resulting in right medial temporal and occipital damage developed Frégoli syndrome. Neuropsychological testing revealed that she had impairment in facial recognition compatible with prosopagnosia. The Frégoli syndrome

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,
A 66-year-old, right-handed male, was admitted to our hospital with difficulty in recognizing faces and colors. He had suffered a stroke in the right occipital region three years earlier that had induced left homonymous hemianopsia, but not prosopagnosia. A neurological examination revealed

Neurologic disorders can produce "secondary" mania, and clinicians must distinguish secondary mania from bipolar disorders (BD). Patients with new and late onset mania require an evaluation that includes a thorough history, a neurologic examination, neuroimaging, and other selected tests. Neurologic
OBJECTIVE
To determine the patterns of clinical presentation, lesion topography, and etiology in patients with ischemic stroke limited to the superficial territory of the posterior cerebral artery (s-PCA).
METHODS
In the Lausanne Stroke Registry (LSR, 1983-1998), we determined the patterns of
Two patients developed a severe and long-lasting inability to recognize familiar faces (prosopagnosia) after a stroke, which was shown by CT scan to be confined to the right hemisphere. The area of softening involved the entire cortico-subcortical territory of distribution of the right posterior
