Non-motor fluctuation
Brief summary
Investigators have developed a comprehensive questionnaire that assesses the presence of non-motor fluctuations (NMFs) in individuals with Parkinson's disease (PD). To date, 189 participants with PD have been assessed for preliminary data analysis prior to developing the penultimate version. At this time the objectives are to: (i) assess the scale's internal consistency and item-to-total correlations; (ii) assess test-retest reliability; (iii) use factor analysis and reliability measures to guide item reduction; (iv) assess construct validity; and (v) assess the scales ability to discriminate between static non-motor symptoms and non-motor symptoms which fluctuate (vi) estimate the relative distribution of cognitive, psychiatric, autonomic, sleep and sensory NMFs in PD patients with motor fluctuations and their impact on quality of life in Parkinson's disease.
