NCT05701852 | Not yet recruiting | Chronic Pain

Motivational Behavioral and Functional MRI Impairment in Patients With Chronic Neuropathic Pain
Sponsor:

Adolphe de Rothschild Ophthalmological Foundation

Brief Summary:

The main hypothesis of this study is that the alteration of the reward circuitry underlying the motivational deficit in chronic pain patients compared to healthy subjects results in a decrease in the capacity for reward learning. The fMRI studies have shown that this type of learning depends on the dopaminergic system innervating key regions of the reward system.
