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 ….
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 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.
How common is Macrocephaly?
Benign familial macrocephaly (external hydrocephalus) accounts for about 50% of cases. It is an autosomal dominant condition that is four times more common in boys. Most affected individuals are developmentally normal. Other family members also have large heads.
Do pinheads exist today?
Microcephaly (from New Latin microcephalia, from Ancient Greek μικρός mikrós “small” and κεφαλή kephalé “head”) is a medical condition involving a shorter-than-normal head. … Mutations that result solely in microcephaly (primary microcephaly) exist but are less common.
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.
Can microcephaly be detected in 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.
How can you prevent microcephaly?

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.
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 you have microcephaly and be normal?
Some children with microcephaly are of normal intelligence and development, even though their heads will always be small for their age and sex. But depending on the cause and severity of the microcephaly, complications may include: Developmental delays, such as in speech and movement.
Can 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.
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 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.
