New study tracks brain health in kids after stem cell transplants
NCT ID NCT07408713
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This observational study will follow 100 children in Denmark who receive a stem cell transplant for blood cancer or other serious blood disorders. Researchers will test their thinking skills, physical abilities, and daily activity before the transplant and for one year after. The goal is to understand how the transplant affects brain function and which factors—like physical fitness or environment—might help recovery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could identify factors that help protect or improve brain function in children after stem cell transplant.
- What could go wrong
- This is an observational study, not a treatment trial. It will not test any new therapy, so it cannot directly improve outcomes.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Patients: In Denmark 20-25 children below the age of 18 years undergo HSCT every year, which means that 100-125 patients will be eligible for inclusion in the study period. To increase the total number of participants available only for 1-year outcome analyses, we will additionally include \~25 patients, in a "catch-up cohort". These participants will undergo the same 1 year follow-up assessments, Parents At least one parent per included patient will be included as a study participant. Inclusion criteria for parents 1. Parent or legal guardian of an included patient 2. Present during the child's hospitalization (the parent most often staying with the child) 3. Able to speak and understand Danish 4. Signed informed consent Exclusion criteria for parents 1\) Inability to understand or complete the questionnaire in Danish
