Clinical studies have found that many epilepsy patients develop epilepsy as a result of brain disorders, the most common of which is hydrocephalus. Of course, not all hydrocephalus will lead to epilepsy, but only those with more severe hydrocephalus will develop epilepsy. The first thing to remember is that hydrocephalus does not always develop into epilepsy, just that the patient has a better chance of doing so. The first thing you need to do is to take a look at the following information. In children, we see enlarged skull, enlarged fontanelle, fullness of tension, cranial suture dehiscence, incompatibility, sunset eyes, vomiting, convulsions, language and motor disorders, mental retardation, and in adults, we see intermittent headache, head swelling, head sinking, dizziness, tinnitus and ear blockage, vision loss, limb weakness, etc. The majority of patients with hydrocephalus are infants, especially those born weeks or months later, who are prone to hydrocephalus and epilepsy. The main manifestation of hydrocephalus is the rapid and progressive enlargement of the infant’s skull a few weeks or months after birth. “(Maceen) sign on percussion. The temporal frontal area shows angry veins, the eye is downwardly rotated, and the upper sclera is often exposed (sunset sign). The sick infant is depressed, unable to lift the head, and in severe cases may be accompanied by brain dysfunction, manifested as epilepsy, visual and olfactory impairment, nystagmus, strabismus, limb paralysis and intellectual impairment. Headache, vomiting and optic nerve papilledema are not obvious because of compensatory enlargement of the infant’s skull. Hydrocephalus is a persistent condition caused by intracranial diseases that increase the amount of cerebrospinal fluid in the skull and enlarge the ventricles due to excessive secretion or (and) impaired circulation and absorption of cerebrospinal fluid. As the amount of hydrocephalus increases and the pressure on the pediatric brain tissue becomes severe, it can cause damage to the brain tissue, abnormal discharge lesions, and consequently epilepsy. The above is an introduction to the connection between hydrocephalus and epilepsy. It can be seen that hydrocephalus can affect the development and normal function of the patient’s brain, leading to brain tissue damage is a common phenomenon, which naturally increases the chance of seizures, so patients with hydrocephalus should pay more attention to it.
