Hydrocephalus

Hydrocephalus defines a condition related to excessive moisture in the brain. Causes, incidence, and risk factors Body fluids in the brain (cerebrospinal fluid or cerebrospinal fluid) are formed in the brain. Cerebrospinal fluid is usually absorbed by the circulatory system through a part of the brain, its cover, and the spinal canal. When circulation and absorption of body fluid are hindered or excess body fluid is generated, the amount of body fluid in the brain becomes larger than usual. Pressure builds up on the brain as fluid accumulates, resisting the skull and damaging or destroying the tissue.

Normal pressure hydrocephalus (NPH) is a type of hydrocephalus that usually occurs in elderly people. The average age of NPH patients is over 60 years old, and NPH differs from other types of hydrocephalus as it progresses slowly over time. The drainage of CSF is gradually blocked, and excess liquid slowly accumulates. A slow increase in the ventricle means that the hydraulic pressure in the brain may not be as high as other types of hydrocephalus. However, the enlarged ventricle still squeezes the brain and causes symptoms (the term "normal stress" is somewhat misleading).

Normal pressure hydrocephalus (NPH) is a special form of chronic traffic hydrocephalus characterized by expanded ventricle and intermittently elevated cerebrospinal fluid pressure only. Features of triple symptoms are Alzheimer's disease, detox walking and urinary incontinence. Since normal blood pressure values ​​can not be obtained with normal measurement, diagnosis of NPH can be determined only by consecutive intraventricular pressure recording (24 hours or more). A dynamic compliance survey may also be useful. Changing the compliance (elasticity) of the ventricular wall and increasing the viscosity of cerebrospinal fluid may play a role in the etiology

Loss of adjustment or balance, changes in gait, memory loss, headaches, or bladder control problems. Hydrocephalus is usually classified as age range, congenital or normal stress hydrocephalus. Congenital hydrocephalus means a disease caused by the condition existing at birth. The main symptoms are headaches, nausea, vomiting, lethargy and so on. Normal pressure hydrocephalus (NPH) is the accumulation of cerebrospinal fluid, which increases the ventricle in the brain with little or no pressure increase. The incidence of NPH in adults occurs mainly in adults over 60 years of age. Patients with NPH are often misdiagnosed as Alzheimer's disease or dementia. There are symptoms that mimic these two conditions.
