Kingston, OntarioAges 18 years+ - NCT04771806Recruiting
MRI-guided adaptive radiation for high-grade brain tumors
This study uses repeated MRI scans with a contrast dye to help doctors tailor (adapt) your radiation treatment over time for a high-grade glioma. It may help improve how accurately radiation targets the tumor as it changes.
Houston, TexasAges 18 years+ - NCT04792554Recruiting
Study of aging around major non-heart surgery
This study looks at changes in health and function in older adults before and after major surgery. It may help doctors understand how “aging” affects recovery and what could improve outcomes.
SingaporeAges 65–100 - NCT04805255Recruiting
Study brain-targeted radiation for limited brain metastases
This study looks at people with a small number of brain metastases who are treated with a focused, staged form of radiation after surgery or to treat the cancer. It may help doctors better understand how well this approach works and who benefits most.
TaoyuanAges 18–84 - NCT04897334Recruiting
Brain stimulation plus rehab to improve thinking after stroke
This study tests whether a noninvasive brain stimulation treatment, combined with rehabilitation, can improve thinking and other “neurocognition” problems after a recent stroke. It may help people whose thinking has been affected by stroke within the past month.
Philadelphia, PennsylvaniaAges 18–90 - NCT04906863Recruiting
Genetic study for early dementia in adults and families
This trial studies genes to better understand why some people develop dementia and memory problems earlier in life. It may help researchers find clearer causes and improve future testing and treatments for families affected by dementia.
New York, New YorkAges 35 years+ - NCT04971850Recruiting
Sleep study for children with possible breathing sleep problems
This trial looks at sleep-related breathing problems (“sleep-disordered breathing”) in children and young adults and how they may affect thinking and memory using sleep study testing plus neurocognitive (thinking) assessments. It may help doctors better understand symptoms and identify who could benefit from treatment.
ParisAges 1–20 - 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 - NCT05045950RecruitingPhase 2
Whole brain radiation that aims to protect thinking skills
This Phase 2 trial tests a modified form of whole brain radiation to see if it can better protect thinking and memory in adults with brain metastases. You may join even if you’ve had other cancer treatments before, as long as your situation fits the study rules.
Milwaukee, WisconsinAges 18 years+ - NCT05129150Recruiting
Assessing brain function with an ultrasound in a day hospital
This trial studies brain function in people who are already going to a day hospital for memory and thinking assessments. It may help researchers better understand cognitive problems and improve how they are evaluated. You would likely be asked to complete an ultrasound exam of the brain and allow your information to be used for the study.
