Specific situations such as sick leave from work, such as neuropsychiatric disorders, have increasingly required the participation of the psychologist in clarifying the facts. And among these neuropsychiatric conditions we emphasize Parkinson's disease (PD). PD is the second most common neurodegenerative disease in the elderly, affecting about 1% of the world's population. Although there is a prevalence of its occurrence in the elderly, it can also appear in younger patients. Mainly characterized by classic motor symptoms (tremor, stiffness, bradykinesia and postural instability), it has also been associated with cognitive and psychiatric changes in recent decades. The most common impairments in PD are attention, executive function, and visuospatial processing, while the most common psychiatric symptoms are depression, apathy, anxiety, and impulsivity. The main objective of this study was to correlate cognitive functioning, psychiatric symptoms and personality traits with the self-perception of the working capacity of patients with PD in relation to their cognitive demands. The sample was for convenience, participating in this study 42 adult patients with PD, between 30 and 65 years of age, of both sexes, in follow-up at the University of São Paulo School of Medicine. The results indicated that depressive symptoms and executive functioning skills, such as fluid reasoning and inhibitory control, were predictors for selfperception of work capacity in relation to cognitive demands. The data found are useful for thinking about programs of attention to this population, either in relation to rehabilitation programs or labor market relocation programs.
