AIM 1 will seek to detect abnormally phosphorylated alpha- synuclein aggregates on targeted skin biopsy in a cohort of people with 5-HT RBD and matched controls (taking SSRIs but without RBD). Aim 2 will use ultra-high field MRI at 7T to examine the pontine region of the coeruleus\u002Fsubcoeruleus complex for evidence of neurodegeneration as well as segment and parcellate REM sleep related neuronal structures. Aim 3 will test for speech deficits. While these aims are independent we suspect that the severity of autonomic, speech and cognitive deficits will correlate with loss of neuromelanin signal on MRI and pathology on skin biopsy.\n\nThe investigation is a longitudinal designed study to examine histopathology, neuroimaging changes and speech function from baseline (Time 1) to a follow-up after 30 months (Time 2). A total of 60 individuals, 30 with 5-HT RBD and 30 controls, will be recruited at Time 1, brought back at Time 2, and tested across all Aims at both study visits.",[76,77,78],"Dementia With Lewy Bodies","Parkinson Disease","REM Sleep Behavior Disorder","2025-07-06",{"date":81,"type":82},"2025-07-08","ACTUAL",{"date":84,"type":82},"2024-02-08",{"date":86,"type":70},"2028-09-01",{"name":5,"class":6},1]
