The direct costs of care were evaluated prospectively in a sample of people with Parkinson's disease (PD) in the United Kingdom in 1998. The subjects were drawn from a random sample of general practitioner practices within a representative sample of 36 Regional Health Authorities and the equivalent. A total of 444 resource use questionnaires with usable(More)
BACKGROUND Depression and anxiety are common in Parkinson's disease (PD) and although clinically important remain poorly understood and managed. To date, research has tended to treat depression and anxiety as distinct phenomena. There is growing evidence for heterogeneity in PD in the motor and cognitive domains, with implications for pathophysiology and(More)
This study investigated face processing abilities in patients with late-onset Parkinson's disease. In the first experiment, the Parkinson's disease patients were impaired on a recognition memory test for unfamiliar faces but showed no deficit relative to controls in recognition memory for words. The Parkinson's disease patients were also impaired at(More)
The potential of computer games peripherals to measure the motor dysfunction in Parkinson's diseases is assessed. Of particular interest is the quantification of bradykinesia. Previous studies used modified or custom haptic interfaces, here an unmodified force feedback joystick and steering wheel are used with a laptop. During testing an on screen cursor(More)
It has previously been reported that unfamiliar face recognition memory is impaired in Parkinson's disease (PD) [(Dewick, H. C., Hanley, J. R., Davies, A. D. M., Playfer, J. R. & Turnbull, C. J., Perception and memory for faces in Parkinson's disease. Neuropsychologia, 1991, 29, 785-802), (Haeske-Dewick, H. C., Are perception and memory for faces influenced(More)
The sleep-wake cycle in Parkinson's Disease (PD) is profoundly disrupted, but less is known about circadian rhythm in PD and its relationship to other important clinical features. This study compared rest-activity rhythms in healthy older adults and PD patients with and without hallucinations. Twenty-nine older adults and 50 PD patients (27 with(More)
Gait disturbance is common in patients with Alzheimer's disease (AD). The aim of this study was to analyse the clinical gait syndromes of patients with AD using Nutt's classification. Fifty-five patients who satisfied the NINCDS-ADRDA criteria for probable AD and 55 controls were recruited from a geriatric and a psychogeriatric unit. Patients with classical(More)
OBJECTIVES Although it is well known that informal caregiving can have negative outcomes, and is an important factor in institutionalization, there is currently no common model to assess psychological distress in caregivers. In this study, we considered the conceptualization of caregiving distress, and present a five-dimension, 17-item Caregiving Distress(More)
