What is the treatment for trisomy 18? The treatment and management of children with Edwards syndrome is dependent upon the severity of findings. [medicinenet.com]

However, there’s no definitive method of treatment and no way to correct the chromosomal abnormality itself. [healthline.com]

Standard Therapies Treatment The treatment of trisomy 18 is directed toward the specific symptoms in each affected individual. Treatment often requires the coordinated efforts of a multidisciplinary team of medical professionals. [rarediseases.org]

The aim of the present study was to clarify the characteristics and prognosis for each trisomy 18 case, and to compare and consider the life prognosis of the two groups. [spandidos-publications.com]

Our doctors had advised that terminating the pregnancy was recommended from a medical standpoint, simply because the prognosis is that the baby won’t live so why have the mother put her health at further risk? The thought disgusted me. [trisomy18.org]
