Abstract
Visual recognition memory was assessed in terms of delay duration, memory load and amount of interference(s) in non-demented patients with Parkinson's disease (PD) using an automated delayed non-matching-to-sample (DNMS) task with trial-unique stimuli. Special attention was focused on the different cognitive functions engaged by these patients in solving this recognition memory task. Thirteen patients with PD, carefully selected according to their stable regimen and anticholinergic medication, were compared to 12 controls matched by age and educational level. Besides the DNMS task, a neuropsychological battery that included tasks carefully selected according to processes potentially required to perform the DNMS task (e.g. attention, executive functions, visual discrimination and motor speed) was administered to the subjects. As compared with controls, patients with PD showed a deficit on most DNMS subscores, except those requiring the least cognitive load. The correlative analysis between the DNMS and other neuropsychological tasks suggests involvement of long-term memory mainly in the DNMS performance for the control group, contrasting with a major involvement of executive functions for the patients with PD. These data indicate that visual recognition memory impairment in non-demented patients with PD is largely due to an executive dysfunction, notably in working memory. Several hypotheses are proposed concerning the neuronal substrates underlying the impairment on the visual DNMS task in PD.
