microcephaly

[‚mī·krō′sef·ə·lē] (medicine) The condition of having an abnormally small head, with a circumference less than two standard deviations below the mean.

Microcephaly

substantial reduction in skull and brain size in the presence of normal dimensions of other parts of the body. Microcephaly is accompanied by mental deficiency, from mild imbecility to idiocy. The causes of microcephaly are viral diseases suffered by the mother during the first three months of pregnancy, toxoplasmosis, and, sometimes, intrauterine meningoencephalitis of the fetus.
