  The single affected individual described by Siu et al [2010] had irritability and profound developmental delay. The Amish patients were able to breast/bottle feed early on, but developed severe irritability and seizures. [ncbi.nlm.nih.gov]

  Case studies report that the infant has seizures early on, is cold all the time, becomes irritable at ages 12 - 16 weeks, and dies before the age of one year. [owlcation.com]

MANAGEMENT: Treatment of manifestations: Treatment is supportive only. Phenobarbital has been used to treat a few children with seizures. Physical therapy may alleviate contractures or other secondary neurologic manifestations. [ncbi.nlm.nih.gov]

Treatment depends upon the problem. In many cases, treatment only helps with symptoms. It may include antiseizure medicines, shunts to drain fluid from the brain, and physical therapy. There are head malformations that do not involve the brain. [medlineplus.gov]

The text concludes by examining the important clinical implications of the recent advances in the field, from recognition of the genetic causes in individual patients to development of new treatments and interventions. [books.google.com]

You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments. [rarediseases.info.nih.gov]

Prognosis Prognosis is very poor: the average life span of affected infants is between five and six months. The documents contained in this web site are presented for information purposes only. [orpha.net]

Prognosis Microcephaly is a lifelong condition with no known cure. The prognosis is usually worse for children who experienced an intrauterine infection or have a chromosomal or metabolic abnormality. [mdpi.com]

Certain physicians have taken up practice in Amish communities in order to study the birth defects prevalent in them and to offer hope of treatment and prevention. [owlcation.com]

However, differences in practice between Amish affiliations may prevent such intermarriage from occurring. Marriage between communities such as Lancaster County and Holmes County, Ohio, occur only rarely. [amishamerica.com]
