We developed a questionnaire to assess autonomic symptoms in patients with Parkinson's disease (PD) and evaluated its reliability and validity. Based on the results of a postal survey in 46 PD patients, 21 multiple system atrophy patients, and 8 movement disorders specialists, items were included according to their frequency, burden, and clinical relevance.(More)
We assessed the clinometric characteristics of rating scales used for the evaluation of motor impairment and disability of patients with Parkinson's disease (PD), conducting a systematic review of PD rating scales published from 1960 to the present. Thirty studies describing clinometrics of 11 rating scales used for PD were identified. Outcome measures(More)
Current IASP diagnostic criteria for CRPS have low specificity, potentially leading to overdiagnosis. This validation study compared current IASP diagnostic criteria for CRPS to proposed new diagnostic criteria (the "Budapest Criteria") regarding diagnostic accuracy. Structured evaluations of CRPS-related signs and symptoms were conducted in 113 CRPS-I and(More)
Experiments were carried out in glasshouses to induce second-growth in potato tubers under controlled conditions. High temperature, irrespective of the water supply, induced second-growth in the tubers; drought did not induce or promote second-growth in these experiments. High temperature promoted the formation of new tubers of the first generation, and(More)
STUDY OBJECTIVES To develop a short and practical scale (SCOPA-SLEEP) that evaluates nighttime sleep and daytime sleepiness. The scale is developed for research in Parkinson disease but may be of value for other somatic diseases. DESIGN Postal survey including 4 instruments, the SCOPA-SLEEP nighttime sleep (5 items) and daytime sleepiness (6 items), the(More)
OBJECTIVE To develop a short, practical instrument that is sensitive to the specific cognitive deficits in Parkinson's disease (PD) for comparing groups in research situations and for assessing change in cognitive functioning over time. METHODS A literature search was conducted to identify the most frequently affected cognitive domains in PD and to select(More)
OBJECTIVE To establish the diagnostic accuracy of the Montreal Cognitive Assessment (MoCA) when screening externally validated cognition in Parkinson disease (PD), by comparison with a PD-focused test (Scales for Outcomes in Parkinson disease-Cognition [SCOPA-COG]) and the standardized Mini-Mental State Examination (S-MMSE) as benchmarks. METHODS A(More)
OBJECTIVE There is a wide range of autonomic symptoms (AS) in Parkinson disease (PD), but the full spectrum has never been evaluated with a validated instrument and in comparison with control subjects. In this study a reliable and valid instrument, the SCOPA-AUT, was used to evaluate the occurrence of AS in a large cohort of patients with PD and control(More)
We evaluated the validity, reliability, and potential responsiveness of the Beck Depression Inventory (BDI) in patients with Parkinson's disease (PD). In part 1 of the study, 92 patients with PD underwent a structured clinical interview for DSM major depression and based on this patients were considered depressed (PD-D) or nondepressed (PD-ND).(More)
Complex Regional Pain Syndrome Type 1 (CRPS-1) responds poorly to standard pain treatment. We evaluated if the N-methyl-D-aspartate receptor antagonist S(+)-ketamine improves pain in CRPS-1 patients. Sixty CRPS-1 patients (48 females) with severe pain participated in a double-blind randomized placebo-controlled parallel-group trial. Patients were given a(More)
