Visual Hallucinations in Lewy Body Diseases
This study uses behavioral tasks and brain scans (MRI and MEG) to learn what happens in the brain when people with Lewy body diseases see things that aren't there. It tests no drug or therapy. The goal is basic understanding that could guide future treatments. No phase is listed because this is basic research.
