A review article in Cognitive deficits in Parkinson’s Disease
Parkinson’s disease (PD) is a common, progressive, disabling, neurodegenerative disorder, that apart from well known motor symptoms, reveals a wide spectrum of non-motor features, that are now widely accepted as part of the clinical aspect, and cognitive decline is a very important part of these non motor presentations. The diagnosis of cognitive decline in PD can be extremely challenging, remaining largely based on clinical and cognitive assessments. Expert work groups have issued diagnostic criteria and methods for PD dementia and cognitive impairement. This manuscript has gathered relevant data in order to obtain an updated review regarding cognitive deficit in PD, from mild stages to dementia. This article has summarized clinical features, diagnostic methods, and therapeutic issues of cognitive decline in PD.
