DEMENTIA WITH LEWY BODIES

This Phase 2 trial tests whether ambroxol, a common cough medicine ingredient, can slow cognitive decline and improve symptoms in people with early dementia with Lewy bodies. 180 participants will receive either ambroxol or a placebo for 18 months. The study measures changes in t…

This study is testing a new blood test to help doctors diagnose Parkinson's disease and similar brain disorders more accurately and earlier. Researchers will use a technique called RT-QuIC to detect misfolded proteins in blood samples from 458 participants, including healthy peop…

This study aims to find the best cutoff values for key Alzheimer's-related proteins in spinal fluid and blood to improve diagnostic accuracy. Researchers will compare results from Alzheimer's patients, those with mild memory problems, people with other dementias, and healthy olde…

This study is testing a new blood test called the AD-seeds-detector that looks for specific protein clumps linked to Alzheimer's disease. Researchers will compare the test results from 1,500 people aged 55-75, including those with Alzheimer's, other dementias, and healthy individ…

This study tests whether adding electroconvulsive therapy (ECT) to usual care can safely reduce severe agitation in people with moderate to severe dementia, including Alzheimer's and other types. Fifty participants will receive ECT sessions with anesthesia, and researchers will m…

This pilot study tests a personalized music therapy program to prevent delirium (sudden confusion) in hospitalized people with neurodegenerative diseases like Alzheimer's or Parkinson's. Thirty participants will receive up to five live music sessions tailored to their preferences…

This small pilot study tests whether a non-invasive brain stimulation technique called tDCS can reduce psychotic symptoms like hallucinations and agitation in people with Lewy body dementia. Thirty participants will receive either real or sham stimulation over two weeks, and rese…

This study compares two antipsychotic drugs, pimavanserin and quetiapine, to see which one better reduces hallucinations and delusions in people with Parkinson's disease or dementia with Lewy bodies. About 94 participants will be randomly assigned to one of the two medications, a…

This study tests whether a gentle, non-invasive brain stimulation technique called tACS can improve memory and thinking in people with Alzheimer's disease, frontotemporal dementia, Lewy body dementia, and related conditions. Two hundred participants will receive either real or sh…

This study follows 800 adults with synucleinopathies—diseases like Parkinson's, Lewy body dementia, and multiple system atrophy—to learn how they develop and change over time. Researchers will track symptoms, biological markers, and early signs like dizziness on standing or dream…

This observational study is recruiting 600 participants to improve detection and understanding of dementia with Lewy bodies (DLB). Researchers will collect clinical data, brain scans, and spinal fluid samples from people with early symptoms like hallucinations or movement problem…

This study uses a special PET scan with a radioactive tracer called [18F]F-DOPA to measure dopamine production in the brains of people with autonomic failure (problems with automatic body functions like blood pressure). The goal is to see if changes in dopamine levels can predict…

This study is gathering information from 700 people with Parkinson's disease or similar conditions who experience freezing of gait—a sudden inability to move their feet while walking. Researchers will track symptoms, walking patterns, and falls over three years using questionnair…

This study looks at why people with Lewy body dementia have sudden changes in attention and thinking, called cognitive fluctuations. Researchers will use skin biopsies, brain scans, and EEG monitoring in 120 participants to link these symptoms to damage in a key brain chemical sy…

This study is following 1,200 people from two memory clinics in Paris to see how sleep patterns, daily routines, and other personal factors relate to different types and stages of dementia. Participants will wear an activity tracker, answer questionnaires, and have cognitive test…

This early-phase study tests a new radioactive tracer called [11C]SY08 to see if it can detect clumps of alpha-synuclein protein in the brain using PET scans. Researchers will scan 40 volunteers, including healthy people and those with Parkinson's disease, multiple system atrophy…

This study is collecting nerve samples and biofluids from 400 people with ALS or peripheral neuropathies to find biological markers for early diagnosis and disease tracking. By analyzing individual cells, researchers hope to identify molecular changes that happen before symptoms …

This study is looking for 500 people with early dementia or mild cognitive impairment to help develop a way to predict how their disease will progress. Researchers will use blood tests and other models to better understand each person's outlook. The goal is to give patients and d…
