What pathological condition may be caused by excessive production of cerebrospinal fluid in the brain?

Hydrocephalus is a pathological condition characterized by an excessive accumulation of cerebrospinal fluid (CSF) within the ventricles of the brain. This condition can lead to increased intracranial pressure, which may result in a range of neurological symptoms and developmental issues. The excess fluid can occur due to overproduction, impaired absorption, or obstruction of the CSF pathways.

In contrast, other conditions listed do not directly involve the excessive production of CSF. Encephalocele refers to a developmental defect where brain tissue protrudes through an opening in the skull; cranial bifida is a type of neural tube defect affecting the formation of the brain and skull; craniosynostosis involves the premature fusion of skull sutures, which may affect the shape of the head but doesn’t directly correlate with CSF production. Thus, hydrocephalus specifically pertains to issues related to cerebrospinal fluid dynamics within the central nervous system.
