Abstract

The prevalence and pattern of cognitive impairment in systemic lupus erythematosus (SLE) patients with (NPSLE) and without (nSLE) overt neuropsychiatric manifestations were investigated. Fifty-two nSLE patients, 23 NPSLE patients and 27 healthy controls were evaluated with a battery of standardized neuropsychological and psychological tests. Disease duration, disease activity index, and current corticosteroid therapy were collected. Cognitive impairment was identified in 14 (26.9%) and in 12 (52.2%) of subjects with nSLE and NPSLE, respectively. Both SLE groups showed a significant impairment compared with controls on tasks assessing verbal and non-verbal long-term memory, and visuoconstructional abilities. In addition, NPSLE patients reported worse performances than both nSLE patients and controls on task evaluating short-term visuospatial memory. NPSLE subjects were significantly more anxious and depressed compared to both nSLE subjects and controls. By multivariate analysis, only depression levels, among clinical variables, significantly predicted cognitive performance. This study shows that cognitive impairment occurs frequently in both nSLE and NPSLE subjects. The higher frequency in NPSLE may be related to coexisting depressive disturbances.
