Abstract：
BACKGROUND:Visual hallucinations (VH) in Parkinson's disease (PD) are associated with PD dementia and have been related to cognitive impairments in non-demented PD patients. Reports on the specific cognitive domains affected are conflicting. The aim of the present study was to investigate the presence of specific cognitive impairments in non-demented PD patients with VH, compared to those without VH. METHODS:We compared the clinical characteristics and neuropsychological test scores of 31 non-demented PD patients with VH with those of 31 PD patients without VH that were carefully matched for sex, age, disease duration and educational level. Several non-motor symptoms, including depression, anxiety and sleep disturbances, were also taken into account, as these may influence cognitive performance. RESULTS:The PD with VH group performed significantly worse on the Trail Making Test part A (p = 0.01) and the Rey Auditory Verbal Learning Test, immediate recall (p = 0.01). In addition, PD patients with VH were more anxious, more depressed and reported more sleep disturbances. Verbal learning scores were not associated with levels of anxiety, depression or sleep disruption, whereas worse Trail Making Test A performance was associated with concomitant sleep disturbances. CONCLUSIONS:In non-demented PD patients, the presence of VH is associated with a cognitive profile characterized by impairments in verbal learning and probably attention. Since these cognitive functions are believed to be non-dopaminergic mediated functions, the present results support the hypothesis that multiple neurotransmitter systems, other than dopamine, contribute to the pathophysiology of VH in PD.
