Parkinson's disease is not just a disorder of movement. People with the condition also may have difficulties with remembering, planning, making decisions and being motivated to act.
Many patients lack 'get up and go' and become apathetic, unable to generate drive to do things. Some may develop impulsive decision-making and make uncharacteristically poor choices in everyday life.
We are performing research on:
We're interested in understanding the brain mechanisms underlying these problems and developing treatments for them. We're also testing people at risk of developing Parkinson's disease, e.g. because they suffer from REM sleep behaviour disorder (RBD) or have a genetic risk factor.
