Final answer:
Hydrocephalus is the accumulation of cerebrospinal fluid in the brain. It can cause swelling and puts pressure on the brain. Treatment usually involves inserting a shunt to remove the excess fluid and relieve the pressure.
Step-by-step explanation:
Hydrocephalus is the accumulation of cerebrospinal fluid (CSF) in the brain, which can cause swelling and put pressure on the brain. CSF is constantly produced in the brain's ventricles and circulates throughout the central nervous system, providing cushioning and removing waste products.
If a ventricle is blocked, CSF builds up and can lead to hydrocephalus. This condition can cause seizures, cognitive problems, and even death if not treated with a shunt to remove the fluid and pressure.
