Abstract
Cognitive changes are an integral part of Parkinson’s disease (PD). Dementia, defined as a global impairment in cognition, occurs in 27% of PD patients, range 14–32% (Lieberman et al., 1979; Lieberman, 1997, in press). A selective impairment in cognition called cognitive impairment without dementia, frontal lobe dysfunction, fronto-striatal dysfunction, or bradyphrenia also occurs (Cooper et al., 1991; Rogers., 1986). Although cognitive impairment without dementia has been extensively studied, it’s prevalence is unknown, and it’s relationship to dementia unclear. Is cognitive impairment without dementia an independent entity, or is it a fore-runner of dementia?
