Hydrocephalus is a medical condition characterized by an accumulation of cerebrospinal fluid (CSF) in the brain's ventricles. This buildup can increase pressure inside the skull, potentially leading to brain damage and other serious complications. It can occur at any age but is most commonly seen in infants and older adults. Symptoms may include headaches, nausea, balance issues, and cognitive difficulties. Treatment for hydrocephalus often involves the placement of a shunt, a flexible tube that helps drain excess fluid from the brain to another part of the body, where it can be absorbed. Early diagnosis and intervention are crucial for managing the condition and improving quality of life.
