Developing a suicide prevention tool for active duty members
This study is for active duty service members who are getting mental health care and have had recent suicidal thoughts. The goal is to develop a tool that helps predict how well treatments may work for preventing suicide, so you and your provider can make better decisions.
Columbus, OhioAges 18 years+ - NCT05615610Recruiting
Electrical stimulation therapy for brain and arm recovery after stroke
This trial tests whether painless electrical nerve stimulation placed on the skin can improve thinking (cognitive function) and arm movement in people living with long-term stroke. If you qualify, you may receive this non-drug therapy and be assessed for changes in memory/thinking and upper-limb movement.
Hong KongAges 50–80 - NCT06832761Recruiting
Lifestyle help for people with early memory concerns
This trial tests whether a lifestyle program can help people with mild memory problems (subjective cognitive decline or mild cognitive impairment) who also have at least two things that increase their risk for dementia, like high blood pressure or lack of exercise. If you're 50 or older and have these memory issues and risk factors, you may be able to join.
AmsterdamAges 50 years+ - NCT03702907Recruiting
Study of aging and a brain sample bank
This study follows adults as they age and may collect biological samples for future research. It could help researchers understand early and late changes related to aging and brain health.
Washington D.C., District of ColumbiaAges 45 years+ - NCT04027244Recruiting
Studying care plans for severe leg blood flow problems
This study looks at how best to manage severe leg ischaemia, a condition where blood flow to the leg is dangerously reduced. It mainly involves patients who are planning an intervention, and some participants may also do special heart imaging tests.
Leicester, LeicestershireAges 18–110 - NCT02800395Recruiting
Study links brain changes to diet and blood markers in Alzheimer’s
This study looks at how diet-related and blood “stress” markers relate to how thinking and memory decline over time in people with Alzheimer’s. It may help researchers find useful biomarkers to better track progression and guide future care.
Pierre-BéniteAges 55 years+ - NCT05025254Recruiting
Online thinking tests for people with Parkinson’s disease
This study tests online “thinking” (cognitive) abilities in people with Parkinson’s disease. It may help researchers better understand how thinking changes over time and how tests can be done from home.
Montreal, QuebecAges 45–90 - NCT04480203Recruiting
Digital coping tools after new breast cancer diagnosis
This trial tests two online programs designed to help people cope after being diagnosed with breast cancer. It may help you manage stress and emotions during treatment or recovery.
OsloAges 20–69 - NCT05353504Recruiting
Testing how gut changes affect food choices
This study looks at whether interventions that change your gut bacteria can change how you decide what to eat. It may help researchers understand the gut–brain link behind eating behavior.
LeipzigAges 18–60 - NCT05399745Recruiting
Study of biliary atresia in children with heart disease
This trial is studying children who have biliary atresia, a serious liver problem, including some who also have tetralogy of Fallot (a congenital heart condition). It also includes healthy children for comparison, and may help researchers understand the illness and treatments better.
CopenhagenAges birth–18 years - NCT02420470Recruiting
An early warning system for diabetic brain changes
This study tests whether an “early warning” approach can detect early changes in the brain related to diabetes before serious problems happen. If you qualify, you may be asked to take part in brain and health assessments to see how well the system works.
Xi'an, ShaanxiAges 40–65 - NCT05305092Recruiting
Study of memory and thinking in early breast cancer
This study checks how breast cancer affects memory and thinking before other treatments start. It may help doctors better understand cognitive changes and who is most at risk.
