Does small head mean microcephaly?
Microcephaly (my-kroh-SEF-uh-lee) is a rare neurological condition in which an infant’s head is significantly smaller than the heads of other children of the same age and sex..
How early is microcephaly 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.
Do Down syndrome babies have small heads?
Height and weight — Babies with Down syndrome are usually smaller than other babies, and they have smaller heads. They may also grow more slowly and may never reach the same heights that typical children do.
Is it bad if your baby is measuring small?
In a nutshell Your baby measuring small for your dates means that your baby’s size is a little smaller than what’s considered average for the stage of your pregnancy. … These measurements don’t necessarily mean your baby will have a low birth weight, or that there’s anything wrong with your baby’s health.
What percentile is considered 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.

What does it mean if my 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 causes a small head circumference?
Microcephaly facts* 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.
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.
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 is considered mild microcephaly?
What is 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.
Can microcephaly be misdiagnosed?
Recently, microcephaly has usually been misdiagnosed only by ultrasound via measurement of head circumfer- ence (HC). Different literatures use different standards for diagnosis of microcephaly with head circumference.
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.
Is microcephaly hereditary?
In some cases, microcephaly may be caused by inheriting an abnormal gene. Microcephaly is an autosomal recessive gene disorder. Autosomal means that boys and girls are equally affected. Recessive means that 2 copies of the gene, 1 from each parent, are needed to have the condition.
Should I worry about my baby’s head circumference?
Measuring the size of a child’s head is done routinely worldwide to screen for possible learning or developmental problems but new research out today [18 May] suggests that differences within the normal range of measurements are common – and mainly due to human error – and should not unduly concern parents.
