Objectives: To investigate the impact of dystonia symptoms upon cognitive functioning, by comparing cognitive performance in focal and generalised dystonia subtypes, and examining the differential contribution of severity of symptoms and mood disorder.Background: Studies investigating the non-motor syndrome in isolated dystonia have

MMPI-2 maintains an extensive empirical base with psychiatric populations, although more recently, neurologically compromised patients have documented unique elevation patterns. This study examined mild-moderate TBI patients, Alzheimer's Dementia patients, and Psychiatric controls on MMPI-2 scales. Participants included 160 outpatients (TBI n = 26, AD n = 74, Psychiatric n = 60). Controlling for family-wise-error, five ANCOVAs were conducted on five MMPI-2 scales, correcting for age and education. TBI and Psychiatric group means were significantly higher than AD group means for scales Hypochondriasis, Depression, and Hysteria at an alpha of .01. Results support previous research with mild TBI patients, and further document a unique pattern of elevations in this population.

RESULTS failed to show distinctions between groups on pattern of memory impairment when using discrepancy comparisons. However, an analysis examining percentage retention scores revealed better maintenance of non-contextual visual information over time in SSD. Findings may suggest deficits in immediate encoding rather than memory decay for some types of memory ability among geriatric SSD. Our failure to document group differences when using discrepancy comparisons may be attributable to relative similarity in pattern between groups or the limited sensitivity of this technique.
