[Advances in research on the pathogenesis of hydrocephalus].

Hydrocephalus is a common neurological disease with complex etiology. It is characterized by the accumulation and continuous growth of cerebrospinal fluid in the ventricular system and subarachnoid space. Hydrocephalus can be caused by congenital genetic factors, brain trauma and cerebral hemorrhage. Through the efforts of many researchers, the pathogenesis of hydrocephalus is being completed, but it has not been fully explained. The imbalance of cerebrospinal fluid production and absorption into the sinus, and disorder of the cerebrospinal fluid circulation pathway or the osmotic pressure maintenance in the ventricle can lead to increased cerebrospinal fluid and ventricular dilatation.
