BackgroundParkinson's disease is a growing concern as the longevity of the world's population steadily increases. Both ageing and Parkinson's disease have an impact on dopamine neurotransmission. It is therefore important to investigate their relative impact on the fronto-striatal reward system. There has been little investigation of reward processing in terms of anticipation and reward outcome in Parkinson's disease. Abnormal responses during reward processing have previously been demonstrated in whole-brain analysis of Parkinson's patients with mild lateralized disease, but the exact impact in regions specific to reward processing is still unknown.
