Cognitive determinants of visual search in patients with Parkinson's disease

Résumé

Introduction/Background Visual search impairments may negatively affect activities of daily living. Few studies explored the cognitive deficits that contribute to impaired visual search in Parkinson's disease (PD). The aim was to investigate the associations between visual search performance and cognitive functions in PD. Material and method Twenty patients with PD [age: 69±8 yo; sex (Men/Women): 16/4] and 15 controls (age: 61±11 yo; sex: 8/7) performed a visual search task where they were instructed to search for a target stimulus (road sign) among distractor stimuli (other road signs). Neuropsychological tests were also administered. Partial correlations (r or r) were analyzed to investigate associations between correct detection times (cDT) of the visual search task with cognitive variables whilst controlling for age. Results In patients, significant partial correlations were found between cDT and Montreal Cognitive Assessment scores (?=?0.65, P=0.002), divided attention of the Useful Field Of View test (?=0.60, P=0.007), interference condition of the Stroop test (r=?0.58, P=0.023), Figure of Rey (?=?0.74, P
