Macrocephaly is the term for an unusually large head. An infant with macrocephaly will have a larger head than most other infants of the same age and sex. In many cases, this condition is benign or harmless. In other cases, it may indicate an underlying medical condition, such as a genetic syndrome or a brain tumor.
Why does my baby have a big head?
One of the most common reasons for macrocephaly is something that doctors call “benign familial macrocephaly.” In other words, big heads run in your family. A doctor might determine that a baby’s big head is inherited by measuring the heads of the parents.
What does a large head circumference indicate?
Children with macrocephaly have a head circumference (the measurement around the widest part of the head) that is greater than the 98th percentile. Sometimes a large head means that there is a problem in the brain which might require surgery.
Does a big head mean intelligence?
New scientific research proves that people with big heads have higher than average intelligence. Edinburgh University researchers, using MRI scans and IQ tests on 48 volunteers, discovered that the larger the head, and therefore the brain, the greater the IQ. A person with a brain of 1,600cc has an IQ of around 125.
What does baby head size indicate?
Another measure of infant growth is head circumference, or the size of your baby’s head. It’s important because it can indicate how well their brain is growing. If your baby’s brain isn’t growing properly, they may have a condition known as microcephaly.
When should I be concerned about my baby’s head shape?

Pediatricians usually measure head circumference only in children under the age of 2, since the head doesn’t grow much after the fontanelles (soft spots) close at around 18 months. Again, head size is mostly genetic — so if you or your partner has a small head, your child may have a petite one too, and vice versa.
What is abnormal head circumference?
Macrocephaly refers to an overly large head. It’s often a symptom of complications or conditions in the brain. There’s a standard used to define macrocephaly: The circumference of a person’s head is more than two standard deviations above average for their age. Or, their head is larger than the 98th percentile.
Do autistic babies have big heads?
The brains of autistic children undergo an abnormal and dramatic growth spurt in the first year of their lives, according to a new study. The growth makes their heads markedly larger than those of normal infants.
Does Big Head mean smart baby?
(FOX CAROLINA) — Researcher from the UK Biobank — a large, long-term biobank study that began in 2007 — found that babies born with big heads are actually likely to be smarter. The study, which was published in the journal Molecular Psychiatry, looked at the link between genes, IQ and overall health.
Are there physical signs of intelligence?
According to researchers, psychologists and scientists, personal beliefs and physical appearance can also indicate intelligence.
Is it bad to have a big head?
It’s not all bad for us meatheads, though. Research has shown that on average, people with larger brains tend to be more intelligent. That said, having a larger head is no guarantee of having a larger brain.
What causes a person to have a big head?
Causes of macrocephaly include: Benign familial macrocephaly – other family members with big heads (inherited) Excess fluid in the brain – benign extra-axial fluid of infancy or hydrocephalus.
What is a normal size baby head?
The average newborn’s head circumference measures about 13 3⁄4 inches (35 cm), growing to about 15 inches (38 cm) by one month. Because boys tend to be slightly larger than girls, their heads are larger, though the average difference is less than 1⁄2 inch (1 cm).
Should I be concerned if my baby’s head is small?

Does head shape affect intelligence?
It was a powerfully influential finding, because at the time, skull size and shape were thought to be connected to intelligence. Now, though, a new analysis suggests the distinguished anthropologist got it wrong: Race or, more properly, ethnicity is a bigger determinant than environment.
