title: Predictors of survival in dementia with lewy bodies and Parkinson dementia.
abstract: Retrospective analysis of 243 autopsy-confirmed cases of dementia with Lewy bodies (DLB) and Parkinson disease with dementia (PDD) showed an average age at symptom onset of 67 years and a median survival of 5 years from symptom onset. Older age at onset, fluctuating cognition, and hallucinations at onset predicted shorter survival; initial parkinsonism with delayed dementia significantly improved survival. Associated Alzheimer pathology also shortened survival. When adjusted for age, gender, and Alzheimer pathology, fluctuating dementia at symptom onset was identified as best predictor of poor outcome.
