Final answer:
Hydrocephalus is a condition caused by an abnormal amount of cerebrospinal fluid (CSF) in the ventricles. It leads to swelling and puts pressure on the brain, causing neurological problems. Treatment may involve the insertion of a shunt to remove the excess fluid.
Step-by-step explanation:
The condition caused by an abnormal amount of cerebrospinal fluid (CSF) in the ventricles is termed hydrocephalus. The ventricles in the brain produce CSF, which normally circulates and is reabsorbed by the bloodstream.
However, when the flow of CSF is blocked or there's an imbalance between production and reabsorption, it can lead to the accumulation of CSF in the ventricles, causing swelling and putting pressure on the brain.
This can lead to neurological problems like seizures, cognitive issues, and in severe cases, it may require the insertion of a shunt to remove the excess fluid and alleviate the pressure.
