The link between brain injuries and Parkinson’s disease

Researchers at the University of Adelaide are running an important study to explore how our brains respond to head injuries and Parkinson's disease.

The team is looking for volunteers who have experienced a concussion or traumatic brain injury after the age of 10, or who are living with Parkinson's disease.

By comparing healthy brains with those affected by head injuries and Parkinson's disease, researchers want to understand what makes some people more vulnerable to long-term health challenges and what helps others stay resilient.

Why this research matters

Many people don't realise how brain injuries can impact long-term brain health. Even mild concussions can increase the risk of developing Parkinson's disease by 56%, while more severe injuries can raise this risk to over 80%.

These injuries are connected to 5 to 15% of all dementia cases. This means that even if someone seems to recover quickly, there could be long-term effects that need monitoring.

Parkinson's disease affects people in different ways. Some experience more tremors, while others struggle with muscle stiffness. Understanding these differences can help doctors provide better, more personalised support to patients and their families.

This research aims to transform how we understand and care for people with brain injuries and Parkinson's disease, offering hope for more targeted management and treatments in the future.
