There are several synonyms used to define neuronal migration disorders, including developmental brain malformations and cortical dysgenesis. These conditions are caused by abnormal migration of neurons during brain development, leading to improper cerebral organization and function. Other terms commonly used for this condition include cortical malformations, migrational abnormalities, and brain migration disorders. Despite having different names, they all refer to the same neurological condition that typically manifests as epilepsy, intellectual disability, and developmental delays. Researchers are still investigating the underlying causes of neuronal migration disorders, but it is known to be a complex disorder influenced by a range of genetic and environmental factors. Gradual progress is being made in diagnosing and treating these conditions.
