The purpose of the present study was to establish how Parkinson's disease (PD) affects working capacity. Altogether, 937 (70%) of 1,343 working-aged members of the Finnish Parkinson Association participated in a questionnaire study. The ages of the subjects were between 29 and 65 years, median 59.0 years; 508 (54%) were men. The median (quartile range) duration of PD symptoms was 7.3 (4.3-11.3) years, and the median self-estimated severity of the disease on the Hoehn & Yahr scale was 2. Only 150 of 937 subjects (16%) were still working: 112 (12%) full-time and 38 (4%) part-time. Among those 343 (37%) who had retired purely because of PD at a median age of 53.4 years, the median working time was 1.7 years after established diagnosis. In part-time work, PD patients had been able to continue for a median of 4.3 years. PD often leads to early retirement; compared with the general Finnish population of similar age, PD patients had retired on the average 6 years earlier. Young age, mild symptoms, and short duration of the disease as well as adjustments enabling easier employment were associated with the possibility to continue longer in the work force.

The prevalence of daytime sleepiness and background factors associated with it were investigated in a study carried out at the UKK Institute. The inquiry took the form of a questionnaire mailed to 1600 people of middle age. Daytime sleepiness was found to be associated with disturbed night sleep. Women were more tired than men, but men slept more frequently during the day. Those suffering from tiredness complained of poor health more than other respondents. Traffic accidents and other mishaps attributable to tiredness had occurred in 1.3% of cases, and almost 5% of male respondents had dozed off while driving at least five times in their lives. The findings indicate a need for increased attention to disturbance of sleep and daytime sleepiness in routine health screening.

Background: Neuropsychiatric symptoms and impairment in performing activities of daily living (ADL) in patients with Parkinson's disease (PD) are strong predictors of the overall caregiver burden and they increase the risk for nursing home admission of the patients. The purpose of the present study was to assess the association of neuropsychiatric symptoms and ADL functions in PD. Methods: A total of 73 community-dwelling PD patients were studied. The mean age of the patient group was 65 years and the mean disease duration was 9 years. The Neuropsychiatric Inventory was used to measure neuropsychiatric symptoms, and ADL abilities were measured by the Alzheimer's Disease Cooperative Study-Activities of Daily Living Inventory. Results: The prevalence of neuropsychiatric symptoms in patients with PD was 73%. The most common symptoms were depression, anxiety, irritability, apathy and agitation. ADL ability correlated significantly with apathy (p < 0.002) even when adjusted for motor symptoms. Conclusion: Apathy was significantly associated with ADL in PD. The result indicates that more attention should be paid to identifying apathy and targeting therapeutic interventions.
