The underlying etiology of primary NPH has not yet been identified. Primary NPH affects adults age 40 years or older, most commonly in adults over 60. [15] Secondary NPH can affect persons of any age and occurs due to conditions such as subarachnoid hemorrhage, meningitis, brain surgery, brain radiation, or traumatic brain injury. [16]
Rates in the developing world may be higher. [5] Normal pressure hydrocephalus affects about 6% of patients over 80. [4] Description of hydrocephalus by Hippocrates dates back more than 2,000 years. [5] The word hydrocephalus is from the Greek ὕδωρ, hydōr, meaning 'water' and κεφαλή, kephalē, meaning 'head'. [6]
[6] [18] Untreated hydrocephalus can lead to increased intracranial pressure and brain damage. Shunts used to treat DWM have a moderate-to-good success rate, but they have a higher-than-average failure rate, which can result in failure to reduce the intracranial pressure or infection, such as meningitis .
Blockage of the aqueduct can lead to hydrocephalus, specifically as a common cause of congenital and/or obstructive hydrocephalus. [ 1 ] [ 2 ] The aqueduct of Sylvius is the channel which connects the third ventricle to the fourth ventricle and is the narrowest part of the CSF pathway with a mean cross-sectional area of 0.5 mm 2 in children and ...
Low-pressure hydrocephalus (LPH) is a condition whereby ventricles are enlarged and the individual experiences severe dementia, inability to walk, and incontinence – despite very low intracranial pressure (ICP). [1] Low pressure hydrocephalus appears to be a more acute form of normal pressure hydrocephalus. If not diagnosed in a timely ...
Survival rate is a part of survival analysis.It is the proportion of people in a study or treatment group still alive at a given period of time after diagnosis. It is a method of describing prognosis in certain disease conditions, and can be used for the assessment of standards of therapy.
L1 syndrome is a group of mild to severe X-linked recessive disorders that share a common genetic basis. The spectrum of L1 syndrome disorders includes X-linked complicated corpus callosum dysgenesis, spastic paraplegia 1, MASA syndrome, and X-linked hydrocephalus with stenosis of the aqueduct of Sylvius (HSAS).
The common symptoms often resemble a new onset of hydrocephalus, such as headaches, nausea, vomiting, double vision, and an alteration of consciousness. This can result in damage to an individual's short-term memory. [10] In the pediatric population, the shunt failure rate two years after implantation has been estimated to be as high as 50%. [23]
