There is no specific treatment for trisomy 13. Treatment varies from child to child and depends on the specific symptoms. More than 90% of children with trisomy 13 die in the first year. Complications begin almost immediately. [medlineplus.gov]

It is important for families to understand the poor prognosis when making decisions about surgical and medical intervention in the neonatal period. [clinicaladvisor.com]
But these dedicated parents are determined to make a better prognosis. "Now when you Google, Trisomy 9 Mosaic, up pops these kids that are smiling," says Ms Davies. "They do have disabilities and they do need extra help, but they are thriving." [newshub.co.nz]
Prognosis [ 1 ] Life expectancy is very limited. Median survival is 2.5 days. About 50% live longer than one week. 5-10% of infants live longer than one year. Profound learning disability and developmental delay occur in survivors. [patient.info]
We called in a clergyperson for one case who candidly said he’d end the pregnancy, so bleak was the prognosis. [blogs.plos.org]

Can trisomy 18 or trisomy 13 be cured or prevented? There is no cure for trisomy 18 or trisomy 13. We are not certain how to prevent the chromosomal error that causes trisomy 18 and trisomy 13. [stanfordchildrens.org]
How can trisomy 18 be prevented? There is no way to prevent the occurrence of trisomy 18. Prenatal screening and diagnosis are available in the general population. [clinicaladvisor.com]
The cause of this is unknown and prevention is not possible. The most important risk factor for trisomy disorders is maternal age. Women in their late 30s and 40s are more likely to have babies with trisomy than younger women. [betterhealth.vic.gov.au]
