Autism Spectrum Disorder (ASD) is a complex neurodevelopmental disorder associated with difficulties in social interaction, verbal and nonverbal communication, and repetitive behaviors or interests. Other characteristics can include unusual responses to sensory experiences, such as sensitivities to noises, textures, tastes, or the way certain objects look. It is referred to as a specrum disorder because impairments range from mild to severe and vary with each individual.
The range of severity applies to each symptom of ASD. That is, some children may rarely use words to communicate, while others may be extremely verbal with advanced vocabulary. Some children may not like to be hugged or touched, while others seek out and enjoy physical touch. ASD is found in all ethnicities, races, and countries, and occurs in more boys than girls.
