Apathy and Impulsivity

We study how people make decisions and how motivation affects decision-making. We also investigate how motivation and decision-making are disrupted in brain disorders such as Alzheimer's disease, Parkinson's disease, stroke and vascular dementia. 

Our research focuses on:

  • Apathy or lack of motivation
  • Impulsivity and risky decision-making

We're trying to understand the mechanisms underlying motivation and decision-making in healthy people and in patient groups. We're also performing research into treatments for disorders of motivation and decision-making.
