Researchers report that they have found a possible explanation why people with Parkinson’s disease experience visual hallucinations. The study was carried out by performing brain scans on the study subjects.
- Patients with Parkinson’s disease have areas of their brains that communicate less with other areas of the brain.
- Parkinson’s patients with visual hallucinations have several other areas of the brain with minimal connectivity to the rest of the brain.
- Areas of the brain that process visual information and maintain attention are usually worst hit.
Future research could explore whether stimulating the brain areas with decreased connectivity could help treat visual hallucinations in people with Parkinson’s disease, the study authors suggested.
