Are bigger heads smarter? If you have a \”big-headed baby\”, you should be wary of these 4 diseases…

People say that \”the bigger the head, the smarter the baby is.\” My baby\’s head feels smaller than other children of the same age. Will it affect his intellectual development? For a long time, some parents have firmly believed that \”babies with big brains will be smarter\” and use this as a basis for judging IQ. It is true that a bigger brain will have more brain cells, but it does not mean that you can predict your baby\’s future IQ. Also, parents, don’t secretly rejoice when your baby has a big head, because abnormal head circumference growth may indicate a certain disease. Are babies with bigger brains smarter? Not really! Although a large brain can perform more operations and integrate information, it is not the decisive factor in IQ. In short, head size is not directly related to IQ, but is related to genetics. Therefore, a baby with a big brain may not necessarily be smart, and a baby with a small brain may not necessarily lag behind in development. As for IQ, 40% is inherited from parents, and 60% needs to be developed and improved from aspects such as diet and nutrition, continuous learning, educational environment, positive thinking, knowledge accumulation, etc. It is not determined based on the size of the head, so parents should stop using it. The size of your head determines your intelligence. Abnormal head circumference reflects disease. Bigger is not always better! Head circumference that is too large or small, and growth that is too fast or too slow require parents to be highly vigilant, because such abnormalities may indicate that the baby is suffering from certain diseases… 1. There is indeed \”water\” in the head of a person with hydrocephalus, but it is just that This water is not that water. The water in the brain is called cerebrospinal fluid. Normally, cerebrospinal fluid will be continuously produced and absorbed to maintain the balance of intracranial cerebrospinal fluid. Once this balance is disrupted by certain factors, it can easily lead to increased fluid accumulation or failure to absorb it, leading to hydrocephalus. The biggest characteristic of babies with hydrocephalus is that their head circumference grows too fast, and their heads are larger than those of children of the same age. (The monthly head circumference growth is 2 to 3 times that of normal babies). In addition, there are other symptoms such as growth retardation, vomiting, bulging anterior fontanel, convulsions, obvious blood vessels in the scalp, and eyes looking downward instead of upward. 2. Megalencephaly Megalencephaly is a hereditary disease. Babies suffering from the disease not only have an enlarged head circumference, but also have larger weight, height, and limbs than normal babies. At the same time, there are also features such as protruding forehead, widened eye sockets, and mental retardation. 3. Intracranial lesions, including intracranial hematoma, brain tumors, brain abscesses, arachnoid cysts, etc., will hinder the absorption of cerebrospinal fluid and cause the head circumference to increase in children. Of course, in addition to the rapid growth of head circumference, there are also symptoms such as unexplained crying, nausea, vomiting, vision loss, convulsions, and dizziness. 4. Infants and young children suffering from simple macrocephaly often have abnormal facial features such as large heads, wide faces, short limbs, and protruding foreheads. Fortunately, there are generally no problems with intelligence. In addition to being wary of \”big-headed babies\”, you should also pay attention to babies with too small a head circumference, because a small head circumference may be the cause of underdevelopment of the brain or microcephaly, and intelligence may also be affected. Therefore, it is recommended that parents seek medical diagnosis promptly when they discover abnormal symptoms in their baby, and also pay attention to the development of their baby\’s head circumference at all times. What is the normal size of a baby\’s head? The head circumference development of infants and young children has certain rules and reference ranges. For example: newborns: head circumference is about 32 cm~34cm; 3 months: head circumference is about 40cm; 1 year old: head circumference is about 46cm; 2 years old: head circumference is about 48cm; 5 years old: head circumference is about 50cm; 15 years old: head circumference is about 53~54cm; parents can refer to the above data As a reference range, once it is found that it is extremely substandard or exceeds the range by a large amount, you must take your baby to the hospital for further examination in time. How to measure baby\’s head circumference? Tool: Soft ruler Position: Let the baby sit up or lie on his back Position range: One week of the maximum circumference of the head Specific method: Fix the 0 point of the soft ruler on the upper edge of the eyebrow arch on one side of the head, and the soft ruler should be close to the scalp (too much hair will The length of the head circumference is the length of the head circumference around the highest point of the occipital tubercle and the upper edge of the eyebrow arch on the other side back to 0. Will having a flat head affect intellectual development? The most common abnormal head shape is that the baby\’s head is flat or tilted when sleeping. This deformation is mainly due to the fact that the baby\’s skull has not yet completely ossified, and there are still growth gaps between the individual bone fragments, making it highly malleable. Therefore, when a part of the baby\’s skull bears the weight of the entire head for a long time, the baby\’s neck muscles will be unable to turn the heavy head, which will cause skull deformation. This will not affect the baby\’s intelligence, so parents do not need to panic. It should be noted that you cannot judge your baby\’s development based on head circumference alone. You must consider head circumference, height, weight and other indicators comprehensively to determine whether your baby is developing normally.
