## In brief

- A study reports that identifiable hallucinatory presences in Parkinson's disease may indicate more advanced disease.
- Hallucinations in Parkinson's typically start as visual illusions and sensations of someone nearby, then can progress to complex visual hallucinations as the disease moves toward dementia.

## Why it matters

The findings suggest that the specific character of hallucinations could serve as a marker of disease progression, which may help clinicians and researchers gauge how advanced Parkinson's is.
