Parkinson’s disease is a fairly common neurological disorder in older adults, estimated to affect nearly 2% of those over age 65. The Parkinson’s Foundation estimates that one million Americans have Parkinson’s disease. Recent studies following people with Parkinson’s over the entire course of their illness estimate that 50% to 80% of those with the disease may experience dementia.
Commonly reported symptoms of Parkinson’s disease dementia include:
- Changes in memory, concentration and judgment.
- Trouble interpreting visual information.
- Muffled speech.
- Visual hallucinations.
- Delusions, especially paranoid ideas.
- Irritability and anxiety.
- Sleep disturbances, including excessive daytime drowsiness and rapid eye movement (REM) sleep disorder.
