CP and microcephaly: Depending on its origin, microcephaly can be classified as primary, in which malformations occur in the early months of pregnancy due to genetic/chromosomal and/or environmental abnormalities, or secondary, initially characterized by normal CP and later by disruption of normal head growth [5] resulting from interactions with environmental factors, such as congenital infections that have secondary effects on the developing inflammatory process and teratogenic reactions affecting CP [6].
