Fatigue and Sleep Issues
Parkinson’s disease causes changes to the brain chemistry that can affect a person’s ability to sleep properly. Some people experience issues sleeping long before any physical symptoms start to arise. These issues include restless leg syndrome, REM sleep behaviour disorder, and insomnia. Up to half of all Parkinson’s patients also state that fatigue is a common symptom. Regardless of how much rest they manage to get, these patients feel full of energy one day and then completely drained the next.
