REM SLEEP BEHAVIOR DISORDER

This study tests whether an oral drug called PXS-4728A can reduce brain inflammation in 40 adults aged 50-80 with isolated REM sleep behavior disorder (iRBD), a condition often leading to Parkinson's disease. Participants receive either the drug or a placebo for 12 weeks, and bra…

This study looks at whether terazosin, a drug usually used for high blood pressure, can slow the progression of Parkinson's disease. Researchers are tracking changes in heart and brain scans of 15 people who are either in early stages or at high risk for Parkinson's. The goal is …

This phase 2 trial tests whether carvedilol, a drug usually used for heart conditions, can slow the loss of dopamine transporters in the brain and delay Parkinson's symptoms. It follows 15 people with REM sleep behavior disorder and other early Parkinson's risk factors over three…

This study investigates whether a combination of skin biopsies, speech analysis, and ultra-high field 7T MRI can detect early signs of Parkinson's disease and dementia with Lewy bodies. It focuses on people with a specific type of REM sleep behavior disorder triggered by serotone…

This study tests whether a special heart scan using a radioactive drug called 123I-MIBG can help identify Lewy body disease, a type of dementia that also affects movement and sleep. Researchers will compare scan results with clinical diagnoses in 50 people who have conditions lik…

This study uses a special brain scan called DaTscan to look at how certain brain diseases affect the brain. Researchers will scan 500 adults with conditions like Parkinson's disease, dementia, mild cognitive impairment, or REM sleep behavior disorder. The goal is to see if DaTsca…

This study is testing whether a 6-month program of online exercise classes, guided meditation, and nutrition advice can improve thinking, sleep, and overall health in people with Parkinson's disease. 60 participants aged 40 to 85 will take part, with some starting the program rig…

This study enrolls 500 adults with a sleep condition called REM sleep behavior disorder (RBD), which often leads to Parkinson's disease or related brain disorders. Researchers will track symptoms like thinking, movement, and smell to develop a rating scale. The goal is to prepare…

This study looks at whether carvedilol, a drug used for heart failure, can reverse early heart changes seen in people with a sleep disorder that puts them at high risk for Parkinson's disease. Fifteen participants with REM sleep behavior disorder or reduced sense of smell will ta…

This study looks at whether terazosin, a drug used for high blood pressure, can change heart nerve activity in people at high risk for Parkinson's disease. Researchers are studying 15 adults with REM sleep behavior disorder (a strong early sign of Parkinson's) to see if the drug …
