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.
Correspondingly, can a child with microcephaly be normal?
Key points about microcephaly in children It is most often present at birth (congenital). Most children with microcephaly also have a small brain and intellectual disability. Some children with small heads have normal intelligence. Microcephaly may be caused by problems during a woman's pregnancy.
One may also ask, 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.
Hereof, how can you prevent microcephaly?
While you're pregnant, you can take steps to try to prevent acquired microcephaly:
- Eat a healthy diet and take prenatal vitamins.
- Don't drink alcohol or do drugs.
- Stay away from chemicals.
- Wash your hands often, and get treated for any illness as soon as you feel sick.
- Have someone else change the litter box.
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.
Is microcephaly life threatening?
These problems can range from mild to severe and are often lifelong. Because the baby's brain is small and underdeveloped, babies with severe microcephaly can have more of these problems, or have more difficulty with them, than babies with milder microcephaly. Severe microcephaly also can be life-threatening.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, andAt 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 soon can microcephaly be 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.What is the prognosis for microcephaly?
The prognosis for a child who has microcephaly depends on the other medical conditions the child has. In general, life expectancy for children who have microcephaly is reduced, and the prospects of attaining normal brain function is poor.

You may find out your baby has microcephaly during pregnancy or after he's born.After birth, a baby with microcephaly may have these signs and symptoms:
- Small head size.
- Failure to thrive (slow weight gain and growth)
- High-pitched crying.
- Little appetite or problems with feeding.
- Muscle spasms.
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.How old is the oldest Zika baby?
The study, the first to comprehensively assess some of the oldest Zika babies in Brazil, focused on 15 of the most disabled children born with abnormally small heads, a condition called microcephaly. At about 22 months old, these children had the cognitive and physical development of babies younger than 6 months.Does microcephaly run in families?
Microcephaly is either caused by exposure to harmful substances during the fetal development, or it may be associated with genetic problems or syndromes that may have a tendency to run in families.What drugs can cause microcephaly?
These include toxoplasmosis, cytomegalovirus, German measles (rubella), chickenpox (varicella) and Zika virus. Exposure to drugs, alcohol or certain toxic chemicals in the womb.What does microcephaly do to the brain?
Microcephaly is a medical condition in which the circumference of the head is smaller than normal because the brain has not developed properly or has stopped growing. Microcephaly can be present at birth or it may develop in the first few years of life.How is microcephaly diagnosed?
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. In many cases, microcephaly may not be seen with ultrasound until the third trimester.What happened to the Zika virus babies?
Zika is a virus that can cause serious problems during pregnancy. If you're pregnant and infected with Zika virus, you can pass it to your baby. Zika infection during pregnancy causes a birth defect called microcephaly and other brain problems. It also may be linked to other serious problems for a baby.When was microcephaly first discovered?
Dr. Morton, who established the clinic as both a pediatric practice and a genetics diagnostic laboratory, saw the first case of Amish microcephaly in 1988 when a family asked him to come and see their child. That family led Morton to dozens of other families who had had children with the same syndrome.What is the normal percentile for head circumference?
