What is the life expectancy of 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 microcephaly caused by?
Causes of congenital microcephaly include: Prenatal infections: Exposure to the Zika virus, especially in the first trimester of pregnancy, can damage nerve cells in the brain. Other infectious agents can also cause microcephaly, including rubella (German measles), chickenpox, toxoplasma and cytomegalovirus.
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 …
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.
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.
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.
What is secondary microcephaly?
Secondary microcephaly occurs when the brain, roughly normal in size at birth, does not grow thereafter. Brain infection, traumatic brain injury, and oxygen deprivation in the brain are causes of postnatal onset.
Can you outgrow microcephaly?
Microcephaly is a lifelong condition that has no cure. Treatment focuses on preventing or reducing problems and maximizing a child’s abilities. Children born with microcephaly need to see their healthcare team often. They will need tests to track the growth of the head.
Do babies with microcephaly grow normally?
Children with a mild form of this disorder may have no other problems. They grow normally during childhood and adolescence and still meet age-appropriate growth milestones as they get older. Others can have severe problems with learning and moving.
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.
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.
Does microcephaly run in families?
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. Some genetic disorders that cause microcephaly are X-linked.
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.
How do you diagnose microcephaly?
Microcephaly may be diagnosed before birth by prenatal ultrasound. This imaging test uses high-frequency sound waves and a computer to make images of blood vessels, tissues, and organs. Ultrasounds let healthcare providers see the internal organs as they function. They also show blood flow through blood vessels.
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.
How is microcephaly transmitted?
Zika virus can be transmitted from mother to fetus during pregnancy, resulting in microcephaly (smaller than normal head size) and other congenital malformations in the infant, collectively referred to as congenital Zika syndrome. Microcephaly is caused by underlying abnormal brain development or loss of brain tissue.
