Hydrocephalus: An Overview
نویسندگان
چکیده
Hydrocephalus is a condition where an abnormal build-up of cerebrospinal fluid (CSF) fluid causes an increase in pressure in the ventricles or subarachnoid space of the brain. It can be caused by either the blockage of CSF flow (i.e. obstructive/non-communicating hydrocephalus) in the ventricular system or by inadequate re-absorption of CSF fluid (i.e. non-obstructive/communicating hydrocephalus). These features result in enlargement of the ventricles (i.e. ventriculomegaly) or subarachnoid space and increase intracranial pressure (ICP). The severity of ICP can compress surrounding brain parenchyma, manifesting into identifiable acute or chronic symptoms depending on the age of onset.

Hydrocephalus is an abnormal increase in the volume of cerebrospinal fluid (CSF), and sometimes increased intracerebral pressure also leads to hydrocephalus. Endoscopic Third Ventriculostomy (ETV) treatment is a new method for hydrocephaly treatment. In this method, in addition to the fact that the patient does not need an implant, the risk of infection is low and in the long term the result is...

متن کاملA Case and Literature Review of Normal Pressure Hydrocephalus in Mixed Connective Tissue Disease
Normal Pressure hydrocephalus (NPH) is characterized by gait apraxia, urinary incontinence, and dementia. Mixed connective tissue disease (MCTD) is an autoimmune connective tissue disease that has never been reported to cause NPH. Our patient was a 67-year man with a one-year history of gradual worsening gait and balance, urinary urgency with urge incontinence and decreased short-term memory. P...
