Summary

This study uses brain scans to understand how early language intervention changes the brains of toddlers (18-30 months) who are late talkers. Researchers will scan 45 children before and after a parent-led speech therapy program to see if brain connections linked to learning and memory improve. The goal is to better understand the brain basis of late talking and help design more personalized treatments.

What this could mean

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

Active substance: behavioural intervention (parent-led speech and language therapy)
What this could lead to: If successful, this could help design more personalized early interventions for late-talking toddlers by revealing how their brains respond to therapy.
What could go wrong: This is a small, early-stage study (45 children) focused on brain imaging, not on proving the therapy works. Results may not apply to all late talkers.
