Could a dementia drug shield kids' brains from radiation damage?

NCT ID NCT03194906

First seen Jun 27, 2026 ยท Last updated Jun 27, 2026

Summary

This pilot study tested whether memantine, a drug used for dementia in adults, could help prevent memory and thinking problems in children receiving brain radiation for tumors like glioma or craniopharyngioma. 41 children aged 6-21 took either memantine or a placebo during radiation. The goal was to see if the study was feasible and if memantine could protect cognitive function. Results are still being analyzed.

What this could mean

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

Active substance
Memantine (a drug used for dementia in adults)
What this could lead to
If it works, this could point toward a way to reduce thinking and memory problems in children after brain radiation.
What could go wrong
This is a very early pilot study with only 41 children, so results may not be conclusive. Memantine is not yet approved for children, and side effects are possible.
