Summary

This study is creating a large database of information about children with hydrocephalus (a condition where fluid builds up in the brain). Researchers will collect details on diagnosis, treatments, and outcomes from multiple hospitals. The goal is to better understand the disease and help design future studies. No new treatments are being tested; this is purely an information-gathering project.
