Effects of dopamine on decision-making in depression

We are recruiting people with no history of mental health, and people with current depression.

The study involves three sessions. The first session takes 1-2 hours, we will do some interviews and questionnaires asking you about your mood, past experience of mental health and family history. The second and third sessions have the same structure: you will drink a drink containing either placebo/LDOPA, then you will wait one hour, we will take a blood sample and you will complete some computer games.

Please email if you have any questions, we will be happy to answer them.

  • No history of mental health disorders

All partcipants cannot currently be taking antidepressants or have used cannabis in past month.
