Dandy-Walker in isolation often brings very few complications. However, individuals with Dandy-Walker often have other conditions as well, and treatment varies depending on the severity of co-occurring conditions.
The most common associated condition is hydrocephalus, which is caused by an accumulation of fluid within cavities of the brain called ventricles, resulting in pressure on the brain. Roughly 70 to 80 percent of people with Dandy-Walker also have hydrocephalus, but with early detection and intervention it is treatable with surgery.
We recommend talking to a pediatrician, physician, or neurologist to best understand your or your loved one’s co-occurring conditions and how to best treat them. For questions about hydrocephalus, we suggest seeking the guidance of a neurosurgeon and contacting the Hydrocephalus Association at info@hydroassoc.org.
