The life expectancy of lissencephaly is generally short. [37][38], Microlissencephaly is considered a more severe form than microcephaly with simplified gyral pattern. Microlissencephaly - PubMed The cerebral cortex in agyria and pachygyria was either very thick, measuring 1020 mm (thick or classic lissencephaly), or less often mildly thick measuring 510 mm (thin lissencephaly, see results). Before birth, complex ultrasounds performed routinely during pregnancy may indicate the presence of a cerebral abnormality, but this method of diagnosis should be complemented by other methods, such as genetic studies and NMR, and the examination is not recommended as part of routine ultrasound examinations, unless family medical history or other reasons for suspecting brain malformation are present. Common causes of death include choking on .

Retrospective analyses of the clinicoradiologic features of these patients allowed segregation of the patients into 5 distinct groups . [citation needed], This phenotype consists of polyhydramnios (probably due to poor fetal swallowing), severe congenital microcephaly, weak respiratory effort, and survival for only a few hours or days. To confirm the diagnosis, providers use DNA studies, such as chromosomal analysis and specific gene mutational analysis, to find the mutation responsible for lissencephaly. Such factors may include intrauterine viral infections, insufficient supply of oxygenated blood to the brain (ischemia) during fetal development, and/or certain genetic mutations. Symptoms of lissencephaly are detected via ultrasound at about twenty-three weeks and require confirmation from a prenatal MRI. If such combination exists with a normal cortical thickness (2.5 to 3mm[4]), it is known as "microcephaly with simplified gyral pattern" (MSGP).

This genetic form of lissencephaly can be observed in more than one child per family, because the mutation can be present in the DNA of a healthy mother. The average global life expectancy from birth is 72 - that's 70 for men and 75 for women. [10], The genes associated with lissencephaly are still being discovered; however, due to advances in genetics individual genes are being identified as the cause of lissencephaly.
