Dementia in Parkinson disease
Parkinson disease (PD) dementia is clinically distinct from other forms of dementia. Core features include a diagnosis of PD and a dementia syndrome leading to impairment in more than one cognitive domain, deficits impairing daily life, and a decline from premorbid functioning. Attention (particularly fluctuations), visuospatial construction, and executive function are more impaired in PD dementia compared with Alzheimer disease. In general, short-term memory and language are less impaired compared to Alzheimer disease.
