Autism, or autism spectrum disorder (ASD), refers to a range of conditions characterized by challenges with social skills, repetitive behaviors, speech and nonverbal communication, as well as by unique strengths and differences. We now know that there is not one autism but many types.
The term “spectrum” reflects the wide variation in challenges and strengths possessed by each person with autism.
Autism’s most obvious signs tend to appear between 2 and 3 years of age. In some cases, it can be diagnosed as early as 18 months. Some developmental delays associated with autism can be identified and addressed even earlier.
Adults with autism who are high functioning may have only mild challenges, while others may have more severe such as impaired spoken language. ASD affects every individual differently.
ASD symptoms can interfere with everyday life, regardless of the severity or how they are exhibited.
