St Louis, MissouriAges 18 years+ - NCT04588285RecruitingPhase 2
Ambroxol for new and early dementia with Lewy bodies
This trial tests whether ambroxol (a mouth medicine) can help people with new or early dementia with Lewy bodies (DLB) or mild cognitive impairment linked to DLB. Participants take the medicine for about 18 months while the study tracks safety and changes over time.
Haugesund, HaugesundAges 50–85 - NCT04643327RecruitingPhase 2
Levetiracetam study to lower dementia risk in Parkinson’s
This Phase 2 study tests whether an added medication strategy can change brain targets linked to memory decline in people with Parkinson’s disease, including those with no memory problems or mild memory changes. It may help lower risk of developing dementia, but you must be able to safely do MRI scans and meet other health and medication rules.
Brisbane, QueenslandAges Any age - NCT04855630Recruiting
Sleep and mild exercise program for thinking and memory support
This study tests whether combining better sleep routines with mild exercise can help with memory, concentration, and thinking speed. To do that, you would wear special devices and complete quick at-home and in-person assessments and a small finger-prick blood test.
Miami, FloridaAges 45–80 - NCT04868994Recruiting
MRI study to help diagnose amyotrophic lateral sclerosis (ALS)
This trial uses a special MRI scan to help diagnose ALS by looking at signs in both nerve pathways. If you’re being evaluated for ALS, it may help doctors confirm the diagnosis sooner and more accurately.
ToulouseAges 18–99 - NCT04916210Recruiting
Study how stroke type affects thinking and recovery
This study looks at what predicts memory and thinking problems after different types of stroke or brain bleeding, and how blood-vessel changes relate to recovery. You may be invited if you recently had a stroke/bleed and can complete a baseline check within 6 weeks.
Phoenix, ArizonaAges 18 years+ - NCT05079464Recruiting
Exercise plus brain stimulation to improve memory in early impairment
This trial tests whether a supervised exercise program, paired with brain stimulation, can improve thinking and memory in people with early “vascular” cognitive problems (not dementia). It may help your brain function before memory loss becomes more severe.
Toronto, OntarioAges 50 years+ - NCT05187819Recruiting
Blood test to help diagnose possible Alzheimer’s
This trial checks whether a simple blood test can help doctors diagnose Alzheimer’s in people who seem to have memory problems. If you’re being evaluated for possible dementia, your doctor may refer you to a memory clinic for testing and follow-up.
StavangerAges 40–100 - NCT05194787Recruiting
Online tests to spot early Alzheimer’s changes
This study looks at whether online motor (movement) and thinking tasks can detect early changes related to Alzheimer’s disease. You may be able to take part if you’re over 50 and do not already have a diagnosis of dementia.
Hobart, TasmaniaAges 50 years+ - NCT05277129Recruiting
Study of the immune response soon after stroke
This study looks at how your body’s immune system reacts in the first hours after a stroke. It may help researchers understand stroke-related immune changes and improve future treatments.
