Macrocephaly may sometimes be a sign of an underlying condition that requires treatment. In other cases, it may occur due to genetics, including a family history of macrocephaly.
What is microcephaly caused by?

What size head 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.
