Autism Spectrum Disorders (ASDs) are a group of complex neurological developmental disabilities that are characterized by impaired social interaction, problems with non-verbal and verbal communication, and unusual or severely limited activities, interests, or behaviors. Other commonly occurring difficulties include unusual responses to everyday sensations such as sounds, touch or visual stimuli, etc., often accompanied by marked difficulty learning how to regulate and control behavioral responses. There are innumerable combinations of how the core deficits manifest themselves and there is no one single characteristic or behavior that is common to all students with Autism Spectrum Disorders.
