NCT06275633

Brief Summary

In this project, patients with Parkinson's Disease (PD) will be characterized by measuring cognitive and motor function and relation to effect of Levodopa. Participants will be patients with Parkinson's Disease and healthy controls. It will be investigated if there is a difference between patients with a good measured Levodopa response and with a poor measured response.
