Positron Emission Tomography (PET) with [18F]-FDOPA clinical trials

In Vivo Involvement of the Cholinergic and Dopaminergic Systems in the Pathophysiology of Apathy.

This study looks at how brain chemicals like dopamine and acetylcholine affect 'apathy' after a stroke. Researchers use special brain scans (PET and MRI) to understand why some people feel a lack of motivation, hoping to find better ways to help them.
