There are many conditions comorbid to autism spectrum disorders, such as fragile X syndrome and epilepsy. In medicine and in psychiatry, comorbidity describes the effect of other diseases an individual patient might have other than the primary disease of interest. About 10–15% of autism cases have an identifiable Mendelian (single-gene) condition, chromosome abnormality, or other genetic syndrome, and ASD is associated with several genetic disorders. However, autism and other autism spectrum diagnoses, including Asperger syndrome, are diagnosed strictly as a cognitive disability, as a brain disorder that begins in early childhood, persisting throughout adulthood, and affecting three crucial areas of development: communication, social interaction and creative or imaginative play.
Famous quotes containing the words conditions and/or disorders:
“Armies, for the most part, are made up of men drawn from simple and peaceful lives. In time of war they suddenly find themselves living under conditions of violence, requiring new rules of conduct that are in direct contrast to the conditions they lived under as civilians. They learn to accept this to perform their duties as fighting men.”
—Gil Doud, U.S. screenwriter, and Jesse Hibbs. Walter Bedell Smith (Himself)
“It no longer makes sense to speak of “feeding problems” or “sleep problems” or “negative behavior” is if they were distinct categories, but to speak of “problems of development” and to search for the meaning of feeding and sleep disturbances or behavior disorders in the developmental phase which has produced them.”
—Selma H. Fraiberg (20th century)
