It may be pathological or harmless, and can be a familial genetic characteristic.
People diagnosed with macrocephaly will receive further medical tests to determine whether the syndrome is accompanied by particular disorders..
Does head size increase with age?
At birth the circumference of the head is about 13–14 inches. It increases by 17% during the first 3 months of life, and by 25% at 6 months of age. It increases by about 1 inch during the 2nd year, and during the 3rd through the 5th year head circumference increases by about one-half inch per year.
Why is baby’s head growing faster than body?
Your pediatrician will pay particular attention to your child’s head growth, because it reflects the growth of her brain. The bones in your baby’s skull are still growing together, and the skull is growing faster during the first four months than at any other time in her life.
What does a large head circumference mean?
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.
When should I be concerned about a small head circumference?

Does head shape affect brain?
During this time some babies develop positional plagiocephaly. This means that there is a flat area on the back or side of the head. Positional plagiocephaly does not affect brain growth or development; it is purely a shape issue.
Why is my head small?
Microcephaly most often occurs because the brain does not grow at a normal rate. The growth of the skull is determined by brain growth. … Conditions that affect brain growth can cause smaller than normal head size. These include infections, genetic disorders, and severe malnutrition.
What is a normal baby head shape?
What is Normal? Parents spend so much time with their baby, recognizing an abnormal head shape can sometimes be difficult. We’ve found it can be helpful to see examples of a normal head shape before looking at abnormal ones. Normally, the head is about 1/3 longer than it is wide and rounded at the back.
Why do I have a big head and small body?
Macrocephaly is usually a symptom of other conditions. Benign familial macrocephaly is an inherited condition. It happens in families predisposed to having larger heads. Sometimes there is a problem with the brain, such as hydrocephalus or excess fluid.
How do you tell if you have a high IQ?
The number actually represents how your results compare to those of other people your age. A score of 116 or more is considered above average. A score of 130 or higher signals a high IQ. Membership in Mensa, the High IQ society, includes people who score in the top 2 percent, which is usually 132 or higher.
Is Macrocephaly a disability?
A rare, genetic, neurological disease characterized by association of macrocephaly, dysmorphic facial features and psychomotor delay leading to intellectual disability and autism spectrum disorder.
Is it normal to have a lumpy head?
Finding a bump on the head is very common. Some lumps or bumps occur on the skin, under the skin, or on the bone. There are a wide variety of causes of these bumps. In addition, each human skull has a natural bump on the back of the head.
Is head size related to intelligence?
Science says larger brains are correlated with higher intelligence, but size alone isn’t the cause. It’s common to hear people say that the size of your brain has nothing to do with your level of intelligence. … So yes: On average, people with bigger heads tend to be more intelligent.
What is a big head a sign of?
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.
Is having a high forehead a sign of 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.
Why is my head changing shape?
The takeaway. While it’s common for the shape of people’s skulls to vary, a new dent or irregularity in your skull can occasionally indicate a serious health condition. Dents in your skull can be caused by trauma, cancer, bone diseases, and other conditions.
How common is Macrocephaly?
Benign familial macrocephaly (external hydrocephalus) accounts for about 50% of cases. It is an autosomal dominant condition that is four times more common in boys. Most affected individuals are developmentally normal. Other family members also have large heads.
What does small head size indicate?
Microcephaly is a condition where a baby’s head is much smaller than expected. During pregnancy, a baby’s head grows because the baby’s brain grows. Microcephaly can occur because a baby’s brain has not developed properly during pregnancy or has stopped growing after birth, which results in a smaller head size.
Does the size of your brain matter?
In healthy volunteers, total brain volume weakly correlates with intelligence, with a correlation value between 0.3 and 0.4 out of a possible 1.0. … Thus, on average, a bigger brain is associated with somewhat higher intelligence.
Does a big head always mean hydrocephalus?
Abnormal head size, sometimes too subtle to perceive with the unaided eye, is the most frequent way hydrocephalus is discovered. However, a large head, also known as macrocephaly, does not necessarily mean a patient has hydrocephalus.
