Background and Purpose—The aim of this study was to determine if side of cerebral hemisphere lesion affects the prevalence and time course of pushing behavior (PB) after stroke. Methods—A total of 1660 patients with acute stroke were investigated. PB was assessed using the standardized Scale for Contraversive Pushing. Risk ratios were used to evaluate the differences in the prevalence of PB bet...

PURPOSE To describe the current treatment research for communication (prosodic, discourse, and pragmatic) deficits associated with right hemisphere brain damage and to provide suggestions for treatment selection given the paucity of evidence specifically for this population. METHOD The discussion covers (a) clinical decision processes and evidence-based practice; (b) a review of right hemisph...

we report an unusual case of hemimegalencephaly (hmg) associated with ipsilateral congenital-infiltrating lipomatosis of the face in a five-month-old boy. hemimegalencephaly is a rare but unique malformation characterized by enlargement of all or parts of a cerebral hemisphere. the affected hemisphere may have focal or diffuse neuronal migration defects, with areas of polymicrogyria, pachygyria...

During the last four years hundreds of Latin American physicians and sanitary engineers have visited the Training Division of The Institute of Inter-American Affairs in Washington, where they have discussed their countries' problems with staff members. Some of them were distinguished professional men who had studied on three continents; others were recent medical school graduates. Regardless of...

The Ruff-Light Trail Learning Test (RULIT) was developed as a neuropsychological measure of visuospatial learning and memory. RULIT scores of patients with right hemisphere and left hemisphere damage, as well as matched controls were compared. Right hemisphere lesion patients scored significantly lower on RULIT measures than did left hemisphere lesion patients and controls. The performance of l...

Although early research suggested that the right hemisphere was dominant for processing faces, more recent studies have provided evidence for both hemispheres being involved, at least to some extent. In this experiment we examined hemispheric specialisations by using a lateralised repetition-priming paradigm with selectively degraded faces. Configurally degraded prime faces produced negative pr...

Kosslyn (1987) proposed that the left hemisphere is better than the right hemisphere at categorical visuospatial processing while the right hemisphere is better than the left hemisphere at coordinate visuospatial processing. In 134 patients, one hemisphere (and then usually the other) was temporarily deactivated by intracarotid injection of sodium amobarbital. After a hemisphere was deactivated...

In the human brain, the dominant hemisphere is more complex than the non-dominant hemisphere. Hence, cerebral ischemia of the dominant hemisphere often leads to serious consequences. This study aims to establish a rodent model of focal cerebral ischemia in the dominant hemisphere. The quadruped feeding test was used to screen 70 male Sprague Dawley rats. From this test, 48 rats with right paw p...
