September is National Hydrocephalus Awareness Month. Hydrocephalus is the most common congenital defect of the brain and spine, with 1 in 500 infants born with this condition. Hydrocephalus is a buildup of cerebrospinal fluid (CSF) within the brain’s cavities called ventricles, causing the brain to swell. This fluid can lead to a variety of neurological problems. Although commonly associated with the pediatric population (it is the most common reason for pediatric brain surgery), hydrocephalus affects those of all ages. Its causes include brain injury, infection, tumor, as well as unknown reasons or as part of the aging process. The only treatment for hydrocephalus is surgery, either for the implantation of a shunt or a process called endoscopic third ventriculostomy (ETV). Hydrocephalus is an automatic qualifier for early intervention (children under three years old). For more information or to make a referral in Missouri, call 1-866-583-2392.
