Sleep and fatigue are two distinct symptoms. General tiredness as a result from lack of sleep can sometimes be mistaken as fatigue but fatigue is lack of energy, exhaustion or weariness despite sleeping well.

There are a range of other sleep issues that can also arise with Parkinson’s, these include:

• Excessive daytime sleepiness
• Insomnia
• Lack of sleep
• Rapid eye movement (REM) sleep behavioural disorder
• Sleeping too much

Lack of sleep or inability to get a full night’s sleep (insomnia) is common for many people with Parkinson’s and can often result from other Parkinson’s symptoms, for example:

• Acting out dreams/thrashing in sleep
• Cramp or dystonia at night
• Difficulty getting to sleep
• Difficulty turning in bed
• Need to go to the toilet at night
• Restless leg at night
• Shouting in sleep
• Sudden jerking in sleep
• Temperature changes at night
• Vivid dreams/nightmares
