Doctor's answer:
Hydrocephalus refers to an increase in the volume of cerebrospinal fluid within the cranial cavity. In addition to neurological signs, it often presents with mental decline or dementia. The most effective treatment methods include lumbar puncture to drain fluid or surgical intervention. After treatment, it is necessary to further investigate the cause of hydrocephalus and then treat the primary disease accordingly.
