What does small head size indicate?
Microcephaly is a condition where the head (circumference) is smaller than normal.
Microcephaly may be caused by genetic abnormalities or by drugs, alcohol, certain viruses, and toxins that are exposed to the fetus during pregnancy and damage the developing brain tissue..
Can babies have small heads normal?
Microcephaly is a condition where a baby’s head is much smaller than normal. It is most often present at birth (congenital). Most children with microcephaly also have a small brain and an intellectual disability. Some children with small heads have normal intelligence.
What is a normal size baby head?
The average newborn’s head measures 13 3/4 in (35 cm) Generally, a newborn’s head is about half the baby’s body length in cm plus 10 cm. So a baby that is 18 inches long would be 45.7 centimeters (18 x 2.54). His or her head would be about 32.9 cm or a little under 13 inches.
What causes a baby to be born with water in the head?
What is hydrocephalus? Hydrocephalus is a condition that occurs when fluid builds up in the skull and causes the brain to swell. The name means “water on the brain.”
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.
Is it normal to have a small head?
Microcephaly most often occurs because the brain does not grow at a normal rate. 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.
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.
Is a small head a sign of Down syndrome?
At birth, babies with Down syndrome usually have certain characteristic signs, including: flat facial features. small head and ears. short neck.
When should I be concerned about my baby’s head size?
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.
Should I worry if my baby has a small head?
Chances are your doctor will detect microcephaly at the baby’s birth or at a regular well-baby checkup. However, if you think your baby’s head is smaller than normal or isn’t growing as it should, talk to your doctor.
How fast do baby heads grow?
Your infant’s head will grow about ½ inch every month for the first 6 months. His or her head will grow ¼ inch per month between 6 months and 1 year of age. His or her head should measure close to 17 inches around by the time he or she is 6 months old and 20 inches by 1 year of age.
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.
Is baby head size important?
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.
Why is my baby’s head not growing?
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 causes a baby’s head to grow too fast?
With hydrocephalus, there’s an imbalance between how fast fluid is made and how quickly it’s absorbed. The result is that it builds up. This can cause the head to enlarge and increase pressure around the brain. There are treatments to help, depending on the underlying cause.
What is the life expectancy of a baby 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 causes water head babies?
In some babies the condition is genetic, such as in babies with congenital aqueductal stenosis. Other conditions, such as neural tube defects (like spina bifida), are also associated with hydrocephalus. Other causes include premature birth, infections, tumors or bleeding inside the brain.
