NCIt definition : GAIA Level 2a Postnatally Diagnosed Congenital Microcephaly is defined by three criteria:
first, a live birth, stillbirth, or spontaneous or therapeutic abortion of at least
24 weeks gestational age (GA), with GA assessed by either a certain last menstrual
period (LMP) date with confirmatory 1st trimester (less than 14 weeks) or 2nd trimester
ultrasound (US) scan OR intrauterine insemination (IUI) OR embryo transfer date; second,
a head circumference (HC) measurement either 2 standard deviations (SD) below the
mean or less than the third percentile as assessed by GA and gender, using appropriate,
standardized reference charts for the population (e.g. WHO growth reference charts
if GA greater than or equal to 37 weeks and Intergrowth-21st reference charts for
GA 24 to 36 weeks); third, one of the following requirements is met: a) the measurement
is taken within the first 24 hours after birth or at the end of the pregnancy taking
into consideration the molding of the head; OR b) the measurement is taken greater
than 36 hours and up to 6 weeks after birth or the end of the pregnancy with no apparent
post-natal insult resulting in microcephaly.;
