”You’ve got water in your brain”, in life, but we often say such things when we describe someone as stupid or dumb. So does water in the brain really have an effect on our intelligence? The medical name for “water in the brain” can be called hydrocephalus or hydrocephalus, and the next name for “water in the brain” is hydrocephalus. Hydrocephalus is not a disease, it is a pathological result caused by a variety of causes. Hydrocephalus is a condition in which the cerebrospinal fluid is increased due to craniosynostosis, which causes the ventricular system to expand or the subarachnoid space to enlarge. Does hydrocephalus really affect intelligence? Hydrocephalus is divided into hydrocephalus in infants, older children and adults. For infants, older children and adults, when hydrocephalus is severe and causes brain atrophy, intellectual development will be impaired, which is commonly known as “stupid”, “dumb”, etc. What are the other manifestations of hydrocephalus? Typical manifestations of hydrocephalus in infants and young children 1. Enlarged head circumference: the infant’s head increases progressively within a few weeks or months after birth, and the growth ratio of the head to the trunk is disproportionate, such as the head is too large and heavy and drops in front of the chest. 2.Enlarged fontanelle and increased tension: When the child is held vertically and quietly, the fontanelle is still inflated and not depressed, and sometimes normal pulsations are not visible. 3.Breaking jar sound: When percussing the head of children with hydrocephalus (frontal-temporal-parietal junction), the sound is like percussing a broken jar or a ripe watermelon. 4, “sunset eyes” phenomenon: the further development of hydrocephalus produces similar to Parinaud’s oculomotor paralysis syndrome, that is, upper gaze paralysis, so that the infant’s eyes can not look up, the so-called “sunset eyes” sign. 5, optic nerve papillary atrophy: primary optic nerve atrophy is more common in infants and children with hydrocephalus, with decreased visual acuity, reduced visual field, defects, and partial blindness. Typical manifestations of hydrocephalus in older children and adults 1.General manifestations: headache, nausea, vomiting, visual impairment, etc. 2.Chronic intracranial pressure hydrocephalus manifestations: bilateral temporal or whole cranial pain, nausea, vomiting, optic nerve papillary edema or optic nerve atrophy, intellectual development disorder, motor dysfunction, etc. 3, normal pressure hydrocephalus manifestation: gait instability, movement disorders of varying degrees, from walking slowly, unstable, balance disorders to can not walk, and finally bedridden; mental disorders as one of the early symptoms, the initial memory loss, the heavy appear dementia, etc., individuals can have the performance of incontinence. Warm tips When our body appears nausea, vomiting, headache, visual impairment or movement disorder without obvious causes, it may be hydrocephalus, and we need to go to the hospital in time to avoid aggravation of the condition.
