Executive dysfunction in non-demented Parkinson's disease patients with hallucinations.
We investigated executive function in Parkinson's disease (PD) patients, and focused on executive dysfunction in PD with hallucinations, but without dementia. ⋯ The study suggests that PD patients with hallucinations, not extensive enough to qualify as dementia, already have executive dysfunction similar to that seen in PDD patients. Executive dysfunction may be an important substrate for hallucinations even when dementia is not yet apparent.
