✓ In the past two to three decades, clinicians and neuroscientists have been studying the functions of the right hemisphere. Neither hemisphere seems to be dominant in the absolute sense. Each appears to be specialized and is dominant for different functions. However, most functions require the cooperation of both hemispheres. When one is damaged, the other can often compensate for the damaged one. Lesions of the left hemisphere are associated with language (speech, reading, and writing) and praxic disorders, and lesions of the right hemisphere can result in visuospatial, attentional, and emotional disorders. The authors review some of the major behavioral disorders associated with right hemisphere dysfunction and concentrate on three major types of disorders — visuospatial, attentional, and emotional. Although not all the behavioral defects associated with right hemisphere damage can be subgrouped under these three types, they are the ones most often associated with right hemisphere lesions.

Processing Deficits

Emotion processing deficits may have an important effect on the quality of life of Alzheimer's disease (AD) patients and their families, yet there are few studies in this area and little is known about the cause of such deficits in AD. This study sought to determine if some AD patients have a disruption in a specific right hemisphere emotion processing system, and to determine if the processing of emotional facial expression is more vulnerable to the pathology of AD than is the perception of emotional prosody. It was specifically hypothesized that patients with greater right hemisphere dysfunction (low spatial AD patients) would be impaired on emotion processing tasks relative to those with predominantly left hemisphere dysfunction (low verbal AD patients). Both groups showed impairment on emotion processing tasks but for different reasons. The low verbal patients performed poorly on the affect processing measures because they had difficulty comprehending and/or remembering the task instructions. In contrast, low spatial AD patients have emotion processing deficits that are independent of language and/or memory and may be due to a more general visuoperceptual deficit that affects the perception of static but not dynamic affective stimuli.

Brain Structure And Function

ObjectiveAsymmetry in brain structure and function is implicated in the pathogenesis of psychiatric disorders. Although right hemisphere abnormality has been documented in obsessive–compulsive disorder (OCD), cerebral asymmetry is rarely examined. Therefore, in this study, we examined anomalous cerebral asymmetry in OCD patients using the line bisection task.MethodsA total of 30 patients with OCD and 30 matched healthy controls were examined using a reliable and valid two-hand line bisection (LBS) task. The comparative profiles of LBS scores were analysed using analysis of covariance.ResultsPatients with OCD bisected significantly less number of lines to the left and had significant rightward deviation than controls, indicating right hemisphere dysfunction. The correlations observed in this study suggest that those with impaired laterality had more severe illness at baseline.ConclusionsThe findings of this study indicate abnormal cerebral lateralisation and right hemisphere dysfunction in OCD patients.

Cognitive impairment has been repeatedly shown to be a delirium risk factor. Much indirect evidence suggests that right-hemisphere dysfunction plays a particularly important role. This retrospective, case-controlled study, from a 148-patient memory loss clinic database, compared neuropsychological measures of hemispheric function in cognitively impaired elderly veterans with and without a history of delirium. Eleven study subjects had a history compatible with DSM-III-R criteria for delirium. Controls selected from the same database had no known history of delirium and were matched for Mini-Mental State Examination scores and Geriatric Depression Scale scores. Compared to the controls, subjects with a history of delirium had significantly lower scores on Object Assembly and Visual Reproduction (p < .05), tests that are predominantly right-hemisphere dependent. There were no significant differences in left-hemisphere measures. It is concluded that right-hemisphere dysfunction may prove to be an important risk factor for delirium.

Poor performances of patients with Tourette's syndrome (TS) on tests requiring visual-perceptual abilities had led previous authors to the suggestion of right hemisphere involvement. We have compared the results of neuropsychological examination of 16 children with TS, with those of 16 children with a lesion of the right hemisphere. No evidence was found of a dysfunction of the right hemisphere in TS.British Journal of Psychiatry (1993), 163, 116–118
