ABSTRACT
Parkinson's disease (PD) is a neurodegenerative disorder affecting 1% of people older than 60 years. One of the abilities that seems vulnerable to the cognitive impairments associated with PD is financial capability. This explorative study aimed to evaluate the extent and type of problems in financial capability of people with PD without a diagnosis of dementia. Participants were 31 people with PD and 62 matched controls. Participants completed an extensive test-battery, including measures for financial capability and cognitive functioning. Compared to controls, the PD-group performed significantly poorer on two financial competence tasks and showed a comparable performance on the other financial capability measures. For 45% of the PD-group, cognitive test performance was indicative of mild cognitive impairment, yet no significant difference was observed in overall cognitive functioning between the PD and control group. In the total sample, only small or medium correlations were found between financial competence and cognition, and between financial capability and the contextual factors of income and financial experience. The findings suggest that in the earlier stages of PD, when cognitive impairments are relatively mild, some problems may be observed in financial competence, yet other domains of financial capability appear less affected. The absence of strong correlations between financial competence and overall cognitive functioning indicates that standard neuropsychological assessments seem inadequate to make financial capability determinations. By offering insight into the financial capability of people in the milder stages of PD, the findings of the present study may aid in the development and provision of tailored support.
ABSTRACT
PURPOSE: People with homonymous hemianopia (HH) benefit from applying compensatory scanning behaviour that limits the consequences of HH in a specific task. The aim of the study is to (i) review the current literature on task-specific scanning behaviour that improves performance and (ii) identify differences between this performance-enhancing scanning behaviour and scanning behaviour that is spontaneously adopted or acquired through training. MATERIALS AND METHODS: The databases PsycInfo, Medline, and Web of Science were searched for articles on scanning behaviour in people with HH. RESULTS: The final sample contained 60 articles, reporting on three main tasks, i.e., search (N = 17), reading (N = 16) and mobility (N = 14), and other tasks (N = 18). Five articles reported on two different tasks. Specific scanning behaviour related to task performance in search, reading, and mobility tasks. In search and reading tasks, spontaneous adaptations differed from this performance-enhancing scanning behaviour. Training could induce adaptations in scanning behaviour, enhancing performance in these two tasks. For mobility tasks, limited to no information was found on spontaneous and training-induced adaptations to scanning behaviour. CONCLUSIONS: Performance-enhancing scanning behaviour is mainly task-specific. Spontaneous development of such scanning behaviour is rare. Luckily, current compensatory scanning training programs can induce such scanning behaviour, which confirms that providing scanning training is important.IMPLICATIONS FOR REHABILITATIONScanning behaviour that improves performance in people with homonymous hemianopia (HH) is task-specific.Most people with HH do not spontaneously adopt scanning behaviour that improves performance.Compensatory scanning training can induce performance-enhancing scanning behaviour.
