Do smarter babies have bigger heads?

Preliminary studies have shown that 1-year-old babies with bigger heads score higher on IQ tests later in life. Doctors know all this — not the Anatole France stuff, the brain weight stuff — so it’s not intelligence they’re after when they measure your newborn’s head circumference.

Do bigger heads mean smarter?

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.

Why does my 2 year old have a big head?

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.

Is head circumference linked to intelligence?

At 8 years, head circumference at birth was no longer associated with IQ, but head growth during infancy remained a significant predictor, with full-scale IQ increasing an average of 1.56 points for each 1-SD increase in growth.

Why do some babies have huge heads?

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 are the benefits of having a big head?

The researchers say that larger head circumference reduced the association between brain cell loss and cognitive impairment. They also say that, as human brains reach 93% of their full size by the age of six, “optimal neural development” in these early years may provide a buffer for later in life.

Does macrocephaly go away?

Macrocephaly Due to Hydrocephalus Doctors call it “benign extra-axial collections of infancy” or “benign external hydrocephalus.” Children typically outgrow the condition by early childhood.

Is it normal for a toddler to have big 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.
