  • Feeding dilemmas, such as for instance trouble swallowing
  • Hearing loss
  • Eyesight problems

These issues can are priced between moderate to serious and tend to be frequently lifelong. Due to the fact baby’s brain is little and underdeveloped, children with serious microcephaly might have a lot more of these nagging issues, or do have more difficulty together with them, than infants with milder microcephaly.

Microcephaly is certainly not a typical condition. State birth defects systems that are tracking believed that microcephaly ranges from 2 children per 10,000 live births to about 12 babies per 10,000 real time births when you look at the u . s. 1

Causes and Risk Facets

The sources of microcephaly in many children are unknown. Some infants have actually microcephaly because of alterations in their genes. Other noteworthy causes of microcephaly, including serious microcephaly, range from listed here exposures during maternity:

  • Particular infections during maternity, such as for instance rubella, toxoplasmosis, or cytomegalovirus
