Delayed Hemichorea Following Temporal–Occipital Lobe Infarction
The presence of hemichorea associated with a lesion in the cortex is exceedingly rare. We report a case of a 62-year-old female who developed delayed left hemichorea after an ischemic infarct in the right temporal–occipital lobe. This case is unique because of the location of infarct and expands our knowledge of hemichorea arising after an ischemic stroke. A 62-year-old female patient was initi...
متن کاملVisual recovery demonstrated by functional MRI and diffusion tensor tractography in bilateral occipital lobe infarction
We report on a patient who showed visual recovery following bilateral occipital lobe infarct, as evaluated by follow up functional magnetic resonance imaging (fMRI) and diffusion tensor tractography (DTT). A 56-year-old female patient exhibited severe visual impairment since onset of the cerebral infarct in the bilateral occipital lobes. The patient complained that she could not see anything, a...
متن کاملRecovery of visual-field defects after occipital lobe infarction: a perimetric study.
OBJECTIVE To assess the temporal course of homonymous visual-field defects due to occipital lobe infarction, by using automated perimetry. METHODS 32 patients with ischaemic infarction of the occipital lobe were studied prospectively, using a Humphrey Visual Field Analyser II. The visual field of each eye was divided into central, paracentral and peripheral zones. The mean visual sensitivity ...
متن کاملVisual localisation in patients with occipital infarction.
Visually directed pointing has been examined in a group of patients with occipital lobe infarction and in an age-matched control group. The visual field ipsilateral to the infarct showed normal localisation; there was no evidence that right sided infarction produced a bilateral disturbance. In quadrantanopia the spared quadrant on the affected side showed abnormal localisation in a few patients...
متن کاملReorganization of Retinotopic Maps after Occipital Lobe Infarction
We studied patient JS, who had a right occipital infarct that encroached on visual areas V1, V2v, and VP. When tested psychophysically, he was very impaired at detecting the direction of motion in random dot displays where a variable proportion of dots moving in one direction (signal) were embedded in masking motion noise (noise dots). The impairment on this motion coherence task was especially...
