Autism Awareness

Part 2

Definition: Autism Spectrum Disorder (ASD) affects a person's ability to understand what they see, hear, and otherwise sense. It is a brain disorder that impacts communication, social interaction, and behavior. It usually appears before the age of 3. No two people with ASD are the same.

Characteristics: 1. Speech, language, and communication impairments 2. Social Interaction impairments 3. Stereotyped or repetitive behaviors 4. Restricted interests (fixations and/or obsessions) 5. Aggressive and/or self injurious behavior

Possible causes: Identified in 1943, to this day no one knows exactly what causes ASD. Research has been done on genetic components, irregulations in several regions of the brain, and/or chemical imbalances. External or environmental triggers are also being studied. Individuals are born with ASD or the potential to develop it.

Statistics: ASD is the second most common developmental disability following mental retardation. It is estimated that 1 out of every 91 children born today has some form of ASD. Research shows that it is 4 times more prevalent in boys than girls, although some recent research contradicts this.

Screening and Diagnosis: There are no medical tests for diagnosing ASD. Professionals screen for ASD using interviews, observation, and evaluations. Even professional opinions are sometimes uncertain, saying "it LOOKS like" or "it COULD be". Even a clear cut autism diagnosis can change over time.
