BACKGROUND AND PURPOSE Most improvement from poststroke aphasia occurs within the first 3 months, but there remains unexplained variability in recovery. Recently, we reported a strong correlation between initial impairment and change scores in motor recovery at 90 days. We wanted to determine whether aphasia recovery (defined as a change from baseline to 90(More)
The presence of a phantom limb (PL) resulting from a cerebral lesion has been reported to be a rare event. No prior study, however, has systematically investigated the prevalence of this syndrome in a group of post-stroke individuals. Fifty post-stroke individuals were examined with structured interview/questionnaire to establish the presence and perceptual(More)
Clinicians have long recognized the enormous variability of recovery among patients with aphasia. Accordingly, the identification of specific factors most important in determining the extent of recovery has been the subject of many investigations. Yet, the reasons for two patients of the same age, nearly identical clinical presentations, and similar MRI(More)
BACKGROUND Patients with Parkinson disease (PD) have deficits in the neurotransmitter systems important for the normal allocation of attention. We sought to examine how the presence of PD influences the spatial allocation of reactive (bottom-up) and volitional (top-down) attention. METHODS To assess the spatial allocation of attention, we used the line(More)
The misidentification of one's own limb (LM) after right hemisphere stroke is a striking phenomenon that is incompletely understood. The authors prospectively studied the natural history and anatomy of LM in 36 patients with hyperacute right middle cerebral artery infarct. Unlike in previous studies, rapid clinical assessment was prioritized. The authors(More)
A 57-year-old right-handed man complained of difficulty using his hands post-coronary artery bypass graft (figure). Neurologic examination revealed signs of callosal disconnection without hemiparesis. When asked to perform limb gestures like "brush your teeth" or "wave goodbye," the right hand performed flawlessly whereas the left hand was severely apraxic(More)
