One impact of megalencephaly is the complete lack of motor development.
2.
It is believed that megalencephaly was discovered in 1972.
3.
A neurological exam will then be performed using the technology of an MRI machine in order to confirm the diagnosis of megalencephaly.
4.
Although very little is still known as to the direct cause of megalencephaly, recent studies have begun to provide early indications of possible sources for its formation.
5.
Prior to diagnoses that used MRI scanning as a way to confirm brain overgrowth, cases of megalencephaly were diagnosed by autopsy in which the physical brain was measured and weighed.
6.
One medical study assessed three patients presenting megalencephaly who showed severely impaired motor and speech development as well as distinct facial abnormalities including skull bossing, a low nasal bridge and large eyes.
7.
Other congenital anomalies of the nervous system include the Arnold-Chiari malformation, the Dandy-Walker malformation, hydrocephalus, microencephaly, megalencephaly, lissencephaly, polymicrogyria, holoprosencephaly, and agenesis of the corpus callosum.
