title: The implications of memory profiles in schizophrenia on vocational and neuropsychological functioning.
abstract: Studies in schizophrenia suggest that verbal learning and memory may distinguish three subgroups of patients: an unimpaired memory profile group and two groups that have memory profiles similar to those seen in cortical and subcortical dementias. Using the Hopkins Verbal Learning Test, Revised edition (HVLT-R), this study attempted to differentiate patients into three memory profile groups and to examine the validity of these groups with respect to vocational outcomes and neuropsychological functioning. Results from this study replicated previous findings and extended them by demonstrating a link to vocational outcome. In addition, the proportion of patients in each group closely resembled that obtained in previous studies. Specifically, the relatively unimpaired memory group (42%) showed overall better memory and neuropsychological performance than the two impaired groups, the subcortical group (38%) showed impaired recall but intact recognition and deficits in visuospatial functioning, and the cortical group (20%) showed deficits in recall, recognition, and sustained attention/executive functioning. There were no clinical differences between the three groups, but both the unimpaired and subcortical groups increased the number of hours worked following a vocational rehabilitation program. Given these differences, more research is warranted to explore the effect of memory impairment subtypes on vocational outcome measures.
