Screening for cognitive deficits in Parkinson's disease with the Parkinson neuropsychometric dementia assessment (PANDA) instrument.Parkinsonism Relat Disord. 2008; 14(2):93-101.PR
Cognitive and affective dysfunctions are frequent but often neglected symptoms in Parkinson's disease (PD). We developed the screening tool Parkinson neuropsychometric dementia assessment (PANDA) with five cognitive tasks and a short depression questionnaire. Healthy subjects and patients without cognitive impairment (PD), mild cognitive disorder (PD-MCD), or dementia (PDD) were examined. The cognition part had a specificity of 91% and a sensitivity of 90% for PDD and 77% for PDD plus PD-MCD patients. The mood questionnaire also had high sensitivity and specificity. We conclude that the PANDA is an economical, easy-to-use and sensitive tool to detect neuropsychological dysfunctions in PD patients in clinical practice.
