Can a Life-Saving transplant leave hidden scars on a Child's mind?

NCT ID NCT07766304

First seen Aug 14, 2026 · Last updated Aug 14, 2026

Summary

This study looks at children aged 6 to 8 who had a stem cell transplant at least two years ago to treat a primary immunodeficiency—a genetic condition that weakens the immune system. Researchers will use standardized tests and interviews to measure the children's thinking skills, attention, memory, and emotional well-being, as well as how they function socially. The goal is to understand the long-term psychological and cognitive effects of this demanding treatment, which are not well known in this specific group of children.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Allogeneic hematopoietic stem cell transplantation (a procedure where a child receives healthy stem cells from a donor to rebuild their immune system)
What this could lead to
If successful, this could reveal how stem cell transplants affect children's thinking, emotions, and social life years later, guiding better support and follow-up care.
What could go wrong
This is a small pilot study with only 30 children, so findings may not apply to all. It observes outcomes but does not test a new treatment, so it cannot change how transplants are done directly.
