In clinical, hydrocephalus in infants and young children, especially within 6 months of infants and young children. Hydrocephalus is caused by intracranial diseases caused by excessive secretion of cerebrospinal fluid or cerebrospinal fluid circulation disorders. In clinical common causes of hydrocephalus have inflammation, cerebrovascular disease, brain trauma can cause fluid to form poly hydrocephalus in the brain tissue of inner product.
First, why hydrocephalus in infants and young children
In 1, congenital malformations: aqueduct stenosis, diaphragm formation or atresia, imperforate interventricular foramen (median aperture of the fourth ventricle or lateral cerebral vascular malformations, empty atresia), spina bifida, tonsillar hernia.
2, infection: intrauterine infection such as virus, parasite and syphilis infection meningitis early failure to control, and the fibrous tissue blocking the circulation channel of cerebrospinal fluid, or inflammation may also cause fetal intracranial subarachnoid cistern, and arachnoid adhesion particle occlusion.
3, hemorrhage: intracranial hemorrhage caused by fibrosis, such as intracranial hemorrhage injury producing malabsorption.
4, tumor: any part of the cerebrospinal fluid can be blocked, more commonly seen in the vicinity of the fourth ventricle, or choroid plexus papilloma.
5, other: some hereditary metabolic disease, perinatal and neonatal asphyxia, severe vitamin A deficiency, etc..
Two, the harm of hydrocephalus
1, will lead to mental retardation
Patients with mental retardation can only mild memory and computational power decline, often accompanied by dull, indifferent, silence, etc.. In patients with severe dementia, a few patients can have irritability, agitation, hallucinations, delirium, and impermanence.
2, will lead to action obstacles
The action obstacle often starts after the mental symptom appears, the patient mainly displays for starts the difficulty, walks slowly is unstable. Muscle tension and tendon reflex Chang Zenggao, positive reflex. Sometimes light hemiparesis.
3, can cause urinary obstruction
The patients were characterized by frequent urination, urinary incontinence, or dysuria, sometimes only in the later stage.
