Summary

This observational study is following 32 boys aged 6 months to 17 years with Pelizaeus-Merzbacher disease (PMD), a rare genetic disorder affecting the brain's white matter. Researchers are measuring biomarkers in spinal fluid and blood, brain scans, and motor and cognitive skills over time. The goal is to better understand how PMD progresses, which could help develop future treatments.
