Relationship among CT scans, neurological exam, and neuropsychological test performance in right-brain-damaged stroke patients.

Right-hemisphere stroke rehabilitation inpatients were assessed by: (1) CT scans; (2) neurological exam; and (3) cognitive and affective psychometric measures. Damage to temporal, parietal, and occipital regions was associated with visual-spatial impairments. Surprisingly, parietal damage was no more related than temporal and occipital damage to severity of visual inattention. While the neurologist's ratings of lability and depression were related to CT-scan measures, patients' self-report of depression was not so related. These findings support a less specific and probably greater interlobule organization of the right, as compared with left, hemisphere, and highlight the need for multifaceted affective assessment in such a brain-damaged group.

Perceptual remediation in patients with right brain damage: a comprehensive program.

This study provided a comprehensive program to treat visual perceptual disturbances associated with right brain damage (RBD). Three types of previously evaluated perceptual remediation were integrated into a sequentially administered remediation program: basic visual scanning, somatosensory awareness and size estimation training, and complex visual perceptual organization. The purpose of the study was to evaluate the immediate (at rehabilitation discharge) and long-term (four months after discharge) effects of this treatment program on patients with RBD. The effects of treatment on ADL and mood state were also examined. Seventy-seven RBD stroke rehabilitation inpatients were studied--including 48 Experimental (E) and 29 Control (C). At rehabilitation discharge, the E group relative to the C group showed greater gains in all three types of perceptual functioning. Four months after discharge from rehabilitation, the C group continued to show gains in perceptual functioning while the E group had reached a plateau. Longitudinal decreases in levels of self-reported anxiety and hostility, but not depression, were noted only for the E group.
