Can microcephaly be seen on ultrasound?
Microcephaly may be diagnosed during pregnancy with ultrasound.
Microcephaly is most easily diagnosed by ultrasound late in the second trimester or early in the third trimester of pregnancy..
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.
Does microcephaly cause retardation?
Signs and symptoms of microcephaly may include a smaller than normal head circumference that usually remains smaller than normal as the child grows, dwarfism or short stature, delayed motor and speech functions, mental retardation, seizures, facial distortions, hyperactivity, balance and coordination problems, and …
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.
What could it mean if baby is measuring small?
Small for gestational age means a baby is smaller than expected for the number of weeks of pregnancy. Some babies are small because their parents are small. But most babies who are small for gestational age have growth problems that happen during pregnancy.
What head percentile 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.
What is the normal percentile for head circumference?

Can a baby with microcephaly be 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.
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.
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.
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.
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.
Does microcephaly go away?
Microcephaly is a lifelong condition. There is no known cure or standard treatment for microcephaly. Because microcephaly can range from mild to severe, treatment options can range as well. Babies with mild microcephaly often don’t experience any other problems besides small head size.
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).
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.
