Autism

Autism (sometimes called “classical autism”) is the most common condition in a group of developmental disorders known as the autism spectrum disorders (ASDs). Autism is characterized by impaired social interaction, problems with verbal and nonverbal communication, and unusual, repetitive, or severely limited activities and interests. Other ASDs include Asperger syndrome, Rett syndrome, childhood disintegrative disorder, and pervasive developmental disorder not otherwise specified (usually referred to as PDD-NOS). Experts estimate that three to six children out of every 1,000 will have autism. Males are four times more likely to have autism than females.

What is Autism?

Autism is not a single disease entity. It is part of a range of developmental disorders known as autistic spectrum disorders (ASD). They begin in childhood and last through adulthood.

Uncovering origins of autism, depression, Parkinson's in fetal brain

The origin of some neuropsychiatric diseases, such as autism, bipolar disorder, or depression, and certain neurodegenerative diseases, Alzheimer's and Parkinson's, can be found in very early stages of brain formation in the fetus. That is, earlier than previously recognized, according to a study by the Hospital del Mar Research Institute and Yale University, published in Nature Communications.
