 The WTOP Charity of the Month is the Hydrocephalus Association. Over 1 million Americans are living with an incurable condition that can only be treated with brain surgery. Hydrocephalus is caused by a buildup of fluid that puts pressure on the brain and can be developed by anyone, from infants to seniors, at any point in their lives. The Hydrocephalus Association provides resources and support to people, as well as funding for critical research to find better treatment options and a cure.
