Patient's question:
While standing, one foot is on the ground while the other foot is on its toes. After the doctor's advice, I received treatment at a cerebral palsy rehabilitation center for three months. Now, I can sit for a short while, my feet can stand but not for long, and they are slightly pigeon-toed. In terms of intelligence, I am fine and can express what I want. Should I still continue treatment?Doctor's answer:
Extracranial hydrocephalus refers to an increase in cerebrospinal fluid in the subarachnoid space of the brain, meaning excessive accumulation of fluid in the space between the skull and brain tissue. Typically, the subarachnoid space contains a small amount of fluid, which is kept constant through a dynamic balance of secretion and excretion. However, if pathological conditions such as meningitis, inflammation, and bleeding exist in the subarachnoid space, an increase in cerebrospinal fluid secretion and impaired excretion can lead to fluid retention in the subarachnoid space. Additionally, when there is frontal lobe atrophy or dysfunction, secondary cerebrospinal fluid increases as the gap between the brain and skull expands. Extracranial hydrocephalus differs from congenital or inflammatory hydrocephalus, which refers to an increase in ventricular hydrocephalus.
