What does a small head mean?

Microcephaly is a medical condition in which the circumference of the head is smaller than normal because the brain has not developed properly or has stopped growing. Microcephaly can be present at birth or it may develop in the first few years of life.

When should I worry about my head circumference?

For a doctor to diagnose macrocephaly, the measurement of the head around its widest part needs to be larger than the 98th percentile. Macrocephaly may sometimes be a sign of an underlying condition that requires treatment. In other cases, it may occur due to genetics, including a family history of macrocephaly.

What head size is normal?

AdultWomanManCircumference (in.)21–2322–24(cm.)53–58.556–61

At what age is microcephaly diagnosed?

Diagnosis. Early diagnosis of microcephaly can sometimes be made by fetal ultrasound. Ultrasounds have the best diagnosis possibility if they are made at the end of the second trimester, around 28 weeks, or in the third trimester of pregnancy. Often diagnosis is made at birth or at a later stage.

Can someone with microcephaly have normal intelligence?

Most children with microcephaly also have a small brain and intellectual disability. Some children with small heads have normal intelligence. Microcephaly may be caused by problems during a woman’s pregnancy. In some cases, it may be caused by inheriting an abnormal gene.

What size head is microcephaly?

Microcephaly is defined as a head circumference 2 standard deviations (SDs) below the mean for age and sex or roughly less than the 2nd percentile. Conversely, macrocephaly is defined as a head circumference greater than 2 SDs above the mean or greater than the 98th percentile.

Is it bad if my baby has a small head?

If your baby’s head is measuring small or is not growing: Your baby’s doctor may be concerned about failure to thrive (when a child doesn’t take in enough calories or is unable to utilize them and doesn’t grow properly as a result).

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.

What does head circumference 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.

Should I worry about my baby’s head circumference?

From 4 to 6 months of age, the head circumference or head growth slows to about 1 cm per month. Now, these are just guidelines and every baby is different so do not become concerned if your baby’s head is growing a little faster than normal.

Are babies with small heads less intelligent?

Head circumference has essentially nothing to do with intelligence and, as long as your child’s head is average-size and regularly growing, there’s no cause for alarm when they come in a bit behind the curve. Still, a handful of preliminary studies have suggested links between brain size, head size, and intelligence.

Why is my head smaller than normal?

The growth of the skull is determined by brain growth. Brain growth takes place while a baby is in the womb and during infancy. Conditions that affect brain growth can cause smaller than normal head size. These include infections, genetic disorders, and severe malnutrition.

What does it mean if baby’s head is measuring small?

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.

What is the life expectancy of someone with microcephaly?

There is no standard life expectancy for microcephalic babies because outcomes depend on so many factors, and the severity of the condition can range from mild to severe. Babies with mild microcephaly may still meet the same milestones like speaking, sitting and walking as a child without the disorder.

What is considered a big head?

The average size male head is 22″ 1/2 and the average size woman head is 21″ 3/4. The one size fits all (OSFA) hats stop at about 23″, so a person would find it difficult finding a hat that fits around a size 7 1/2 and above. In the hat world, head sizes over 23″ 3/8 would be considered a big head.

Does a small head always mean microcephaly?

Microcephaly is a birth defect in which a baby’s head is smaller than expected, compared to babies of the same sex and age. Babies with mild microcephaly often don’t have problems other than small head size.

What is a big head a sign of?

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.

When can microcephaly be detected?

Although microcephaly and intracranial calcifications are typically detected during ultrasounds in the late second and early third trimester of pregnancy, these findings might be detected as early as 18-20 weeks gestation.
