Early infantile epileptic encephalopathy (EIEE), also known as developmental and epileptic encephalopathy (DEE), is characterized by frequent tonic spasms of early onset within a few months of life, and a suppression-burst pattern in electroencephalography (EEG). Many causes have been considered for EIEE. It has been reported that 75% of the cases subsequently evolve to West syndrome, and later a much smaller number progress to Lennox-Gastaut syndrome.

Description
Intellectual developmental disorder, formerly known as Mental retardation (MR), is a neurodevelopmental disorder characterized by low intelligence quotient (IQ) and deficits in adaptive behaviors. Most causative genes identified so far are either located on the X chromosome or are associated with an autosomal recessive mode of inheritance. Recently, a lot of genes associated with autosomal dominant mental retardation have been identified.
