Social and clinical determinants of quality of life in Parkinson’s disease in Austria: a cohort study

Parkinson’s disease (PD) is associated with a reduction of health-related quality of life (HrQoL). Demographic and clinical determinants of HrQoL in PD have been previously investigated, but less is known about its social determinants. Data on HrQoL in Austrian patients with PD are not available. The objective of this cross-sectional survey was to evaluate HrQoL of Austrian patients with PD and to provide a comprehensive analysis of its social and clinical determinants. Outpatients (n = 100) with idiopathic PD were recruited in the Department of Neurology of the University Innsbruck. Clinical status was estimated using the Unified Parkison’s Disease Rating Scale (UPDRS). HrQoL was evaluated using a generic instrument, the EuroQol (EQ5D and EQ-VAS). Independent determinants of HrQoL were assessed in multivariate regression analysis. The proportion of PD patients with moderate or severe problems in at least one dimension of the EQ5D was significantly higher than in the general population (90.1 vs. 35.1%, P < 0.001). The mean EQ-VAS score in PD was lower than in the general population (48.9 ± 19.6 vs. 77.0 ± 20.8, P < 0.001). Social support (number of household members) was identified as an independent social determinant of HrQoL. Demographic and clinical determinants were age, depression, UPDRS and motor fluctuations. The analysis of determinants of HrQoL showed that a greater attention should be paid to social support and home care. Our data on HrQoL in PD should be considered in the development of new health care programs.     

Progressive multifocal leukoencephalopathy presenting with an isolated focal movement disorder.

Progressive multifocal leukoencephalopathy (PML) is a rare but fatal papovavirus infection of the central nervous system predominantly affecting immunocompromised patients. Although the basal ganglia circuitry may be involved in the pathology of PML, movement disorders are exceedingly rare as presenting symptoms and have not been described as isolated features in such patients. We report a previously healthy, immunocompetent 24-year-old woman with histologically proven PML who presented with a focal movement disorder of the left arm as an isolated symptom for many months before diagnosis.     

Time course of symptomatic orthostatic hypotension and urinary incontinence in patients with postmortem confirmed parkinsonian syndromes: a clinicopathological study

OBJECTIVE: Although both orthostatic hypotension and urinary incontinence have been reported in a number of parkinsonian syndromes, such as Parkinson's disease (PD), multiple system atrophy (MSA), dementia with Lewy bodies (DLB), corticobasal degeneration (CBD), and progressive supranuclear palsy (PSP), differences in the evolution of these features have not been studied systematically in pathologically confirmed cases. METHODS: 77 cases with pathologically confirmed parkinsonian syndromes (PD, n=11; MSA, n=15; DLB, n=14; CBD, n=13; PSP, n=24), collected up to 1994, formed the basis for a multicentre clinicopathological study organised by the NINDS to improve the differential diagnosis of parkinsonian disorders. The present study determined the time course-that is, latency to onset and duration from onset to death, of symptomatic orthostatic hypotension, and urinary incontinence in the NINDS series. Furthermore, the diagnostic validity of a predefined latency to onset within 1 year of disease onset of symptomatic orthostatic hypotension or urinary incontinence was analysed. RESULTS: Significant group differences for latency, but not duration, of symptomatic orthostatic hypotension and urinary incontinence were found. Latencies to onset of either feature were short in patients with MSA, intermediate in patients with DLB, CBD, and PSP, and long in those with PD. Symptomatic orthostatic hypotension occurring within the first year after disease onset predicted MSA in 75% of cases; early urinary incontinence was less predictive for MSA (56%). CONCLUSION: Latency to onset, but not duration, of symptomatic orthostatic hypotension or urinary incontinence differentiates PD from other parkinsonian syndromes, particularly MSA.
