Quick Answer: What Is Secondary Microcephaly?

Is microcephaly hereditary?

In some cases, microcephaly may be caused by inheriting an abnormal gene.

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 is the life expectancy of a child with microcephaly?

Babies with mild microcephaly may still meet the same milestones like speaking, sitting and walking as a child without the disorder.

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.

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.
