instruction: What is Autism and how varied is the spectrum?
context: The autism spectrum, often referred to as just autism, autism spectrum disorder (ASD) or sometimes autism spectrum condition (ASC), identifies a loosely defined cluster of neurodevelopmental disorders characterized by challenges in social interaction, verbal and nonverbal communication, and often repetitive behaviors and restricted interests. Other common features include unusual responses to sensory stimuli and a preference for sameness or unusual adherence to routines.
  Autism is generally understood to be a spectrum disorder, as it can manifest differently in each person: any autistic individual is likely to show some, but not all, of the characteristics associated with it, and the person may exhibit them to varying degrees and frequencies.There is large variation in the support needs of autistic people, and some are nonspeaking, while others have proficient spoken language.
response: Autism is a highly variable neurodevelopmental disorder that is generally thought to cover a broad and deep spectrum, manifesting very differently from one person to another. Some have high support needs, may be non-speaking, and experience developmental delays; this is more likely with other co-existing diagnoses. Others have relatively low support needs; they may have more typical speech-language and intellectual skills but atypical social/conversation skills, narrowly focused interests, and wordy, pedantic communication.They may still require significant support in some areas of their lives. The spectrum model should not be understood as a continuum running from mild to severe, but instead means that autism can present very differently in each individual.How a person presents can depend on context, and may vary over time.
