Prognosis
Prognosis The prognosis for children with lissencephaly depends on the degree of brain malformation. Many will die before the age of 10 years. The cause of death is usually aspiration of food or fluids, respiratory disease, or severe seizures. [cmcdfoundation.org]

Etiology
They have been described many forms of lissencephaly and ranking is based on the associated malformations and the underlying etiology. [ivami.com]
There are several types and classification (Dobyns and Leventer, 2003), based on associated malformations and etiologies. [webmedcentral.com]
They are organised into groups, and further divided into clinical, etiological or histopathological sub-types. [orpha.net]
