While Parkinson's is widely known for motor symptoms such as tremor or poor balance, what happens beneath the surface can be just as significant.
Parkinson’s disease occurs when the brain stops producing enough dopamine - the chemical responsible for controlling movement, balance, automatic functions of the body and mood.
Many of its lesser-known symptoms are ones you simply can't see, including sleep disturbances like acting out dreams and sleep talking, persistent fatigue and a slowing of thoughts.
Around half of all people with Parkinson's also experience anxiety and depression. This can often include apathy, a loss of interest in people and activities caused by low dopamine.
Letting family and friends know these are recognised symptoms can make a real difference.
If you or someone you love needs support, call the Hospital Research Foundation - Parkinson’s info line on 1800 644 189 for counselling, information, and guidance.
A free 1:1 nursing service is also available to provide information of how to manage symptoms and connect with community supports.
