Redefining autism

Researchers are now defining Autism into 2 separate categories, complex and essential autism. Complex autism includes dysmorphic features, seizures and lower cognitive ability, and are due to chromosomal abnormalities. Essential autism is the majority of cases (70%) and sufferers lack dysmorphic features. Dysmophic features include a small sized head, and 6 other defining abnormal features. Separating children into these subgroups allow a better idea of prognosis and further risk with pregnancies in the family as they are genetically dissimilar. Autistic children have problems interacting socially with people, difficulty with language and often express repetitive tendencies. 24,000 American children are diagnosed with autism or autism spectrum disorder (Asperger's disorder, and pervasive developmental disorders) each year.
