This information is provided directly by researchers and we recognise that it isn't always easy to understand. We are working with researchers to improve the accessibility of this information.


Aside from typical movement symptoms, individuals with Parkinson’s disease also have an increased risk of developing impulse control disorders, such as pathological gambling, hyper-aggression and binge eating.

Dopamine medications remain the best method to treat motor symptoms, such as tremor, but are the greatest risk factor for impulse control disorders in Parkinson’s. These behaviours can present severe negative implications for people affected by Parkinson’s and their families, yet there is currently no reliable way to identify individuals who are at risk of developing an impulse control disorder.

The purpose of this study is to examine new measures at the level of the muscle and brain to reveal sensitive markers of impaired inhibitory control that might indicate a higher risk of developing impulse control disorders. Participants’ performance on a cognitive-motor task will be investigated. During this task, several measures of muscle and brain activity will be taken, involving non-invasive recording of brain electrical activity, muscle recording, and non-invasive brain stimulation techniques.

To isolate the effects of the disease pathology from the effects of dopamine medication on impulse control, we will recruit 3 study groups:

- Healthy older adults (control group)
- Individuals with PD who are not yet taking medication
- Individuals with PD who are taking ropinirole as a part of their medications

Start dates may differ between countries and research sites. The research team are responsible for keeping the information up-to-date.
