Dallas, TexasAges 55 years+ - NCT05540613Recruiting
Tai Chi versus exercise to help thinking in mild memory loss
This study compares Tai Chi with conventional exercise to improve thinking and memory in older adults who have mild cognitive impairment. If you qualify, you may be asked to do a supervised exercise program and be tested on thinking abilities over time.
Hong KongAges 50 years+ - NCT05661448Recruiting
Online cognitive health program for people with psychosis
This study tests an online, group-based program aimed at supporting thinking and memory (“cognitive health”) for people living with psychosis. It may help by teaching strategies and monitoring progress, while keeping participation safe through clinician judgment and emergency planning.
Vancouver, British ColumbiaAges 18 years+ - NCT05667857Recruiting
Tracking brain, mood, and quality of life after immunotherapy
This study follows people who have had advanced cancer and are now stable after immunotherapy, to see how thinking, mood, and daily life change over time. Some participants may also do an integrative brain-training program if they have memory or thinking problems.
Brussels, Brussels CapitalAges 18 years+ - NCT05708001Recruiting
Testing brain stimulation to improve memory in mild impairment
This study tests whether a noninvasive brain stimulation method (tACS) can improve memory in people with mild cognitive impairment (MCI). A caregiver also helps with the stimulation during the study, and success is measured through study visits and memory-related evaluations.
GenevaAges 55–85 - NCT05708716Recruiting
Diet and brain training for people after blood cancer
This study tests whether a combined diet plan and structured brain (cognitive) training can improve thinking and memory in people who have had blood cancer. It may help survivors who already have mild-to-moderate thinking problems.
Birmingham, AlabamaAges 21 years+ - NCT05731414Recruiting
Testing behavior programs to improve outcomes in schizophrenia
This study looks at how a behavioral program (including remediation and behavior-based techniques) may improve outcomes for adults with schizophrenia-spectrum conditions. You may be eligible if you meet basic age/language needs and haven’t done certain therapies recently.
Scarborough Village, OntarioAges 18–65 - NCT05790707Recruiting
Ablation for persistent atrial fibrillation to help memory
This study checks whether a procedure called atrial fibrillation ablation can slow memory problems in people who already have mild cognitive impairment. Participants will be tested on thinking and memory before and after treatment to see if the procedure helps.
AngersAges 60–80 - NCT05815329Recruiting
Study of changes in people who feel their thinking is getting worse
This study looks at how people’s thoughts and memory feel to them when they report subjective cognitive decline, using questionnaires and assessments. It may help researchers understand this early “thinking feels worse” stage and what it looks like in real life.
Montescano, PaviaAges 55 years+ - NCT05877196Recruiting
Adaptive walking and fitness program for mild memory decline
This study tests an “adaptive” exercise plan that adjusts over time to help improve aerobic fitness and your body’s fitness response in people with mild memory problems or early Alzheimer’s. It may help you safely build the kind of fitness that supports brain health, while researchers monitor changes with fitness testing and blood work.
Phoenix, ArizonaAges 65 years+ - NCT05885295Recruiting
Testing thinking and memory after stroke using cognitive exams
This study looks at how thinking and memory change after a stroke using short cognitive tests. It may help researchers better understand which brain changes affect thinking, and how to measure them accurately.
LondonAges 18 years+ - NCT05886114Recruiting
Lifestyle program to help older adults at risk of memory decline
This trial tests a multi-part lifestyle program to help older adults who may be starting to decline in thinking and memory. It may help slow cognitive decline by combining lifestyle changes over 24 months.
