There is a folk saying that children with big heads are smart. In fact, a child’s intelligence is not proportional to the size of his or her head, but is related to intelligence, life experience, opportunity, effort and many other factors. 6 months old baby boy Jie was born soon after, his head appeared to be much larger than children of the same age, who saw all praise “this child’s head is big, smart”, the family could not mention how happy to hear it. However, Xiaojie’s head is growing bigger and bigger, but the intelligence is not long, eyes always look down, look a little dull. Normal children will raise their heads at 3 months, and roll over at 4 months, but he will only do so a month or two later. The family took Jie to the hospital for a checkup, and it turned out to be hydrocephalus. Although there are some differences in the shape and size of the head of children of the same age and gender, these differences are within a certain range. If the head circumference is more or less than 2 standard deviations from the average of the same age and gender, the head circumference is abnormal. As you can see, a large head circumference is not only unintelligent, but may also have certain abnormalities that affect the development of intelligence. Is hydrocephalus water in the brain? Hydrocephalus can occur at any age, but most occur within the first 6 months of life. It is a pathological condition in which the secretion, circulation or absorption of cerebrospinal fluid is impaired, resulting in an increase in intracranial cerebrospinal fluid and causing abnormal enlargement of the ventricles and/or subarachnoid space. The basic feature is that the excess cerebrospinal fluid produces an increase in intracranial pressure, thus enlarging the space occupied by normal cerebrospinal fluid. If hydrocephalus occurs before the closure of the cranial sutures, the enlargement of the skull is abnormal and significant. What are the risks of hydrocephalus? I: Mental retardation. In mild cases, there is only mild memory and calculation loss, often accompanied by slowness, indifference, and reticence. Severe patients may show dementia, and a few patients may have agitation, irritability, crying and laughing, hallucinations, delirium, etc. Second: Mobility disorders. Mobility disorders often begin gradually after the appearance of psychiatric symptoms. Patients mainly show difficulty in starting, slow and unstable walking, often increased muscle tone and tendon reflexes, positive reflexes, sometimes presenting light hemiparesis. Third: urinary and bowel disorders. Patients mainly show frequent urination and defecation, urinary incontinence or difficulty in urination, and sometimes these symptoms only appear in patients in advanced stages. Failure to treat hydrocephalus in a timely and standardized manner can easily cause disabilities such as visual, intellectual, hearing, speech and physical disabilities in children. Many parents of children with hydrocephalus do not know enough about hydrocephalus and take many detours in the process of seeking medical treatment, resulting in some children coming to the hospital with advanced hydrocephalus and serious damage to brain function and even symptoms of cerebral palsy, which is often irreversible. What are the manifestations of pediatric hydrocephalus? The most typical manifestation of children with hydrocephalus is a large head with a thin and bright scalp, and sometimes the veins of the scalp can be seen to be filled and distended. Although the child’s head is large, the face is relatively small. There are also often manifestations such as downward displacement of the eyeballs, sclera exposure, feeding difficulties, difficulty in lifting the head or even convulsions, and there may also be mental inactivity, drowsiness or irritability, easy vomiting, paralysis and difficulty in walking. Some hydrocephalus clinical manifestations are not obvious, the child’s head is large, poor intelligence, walking badly, language is not fluent, urine control is not good, all should go to the hospital for examination, if early detection, timely treatment, intelligence can still be restored to normal. Therefore, as parents of infants, we should observe carefully, and if we find that our children have the above symptoms, we should see a doctor in time.
