Could You Have Symptoms of Autism?
Autism spectrum disorder (ASD) occurs in all age, racial, ethnic, and socioeconomic groups. It is generally characterized by social and communication difficulties and by repetitive behaviors. Often, severe forms of ASD are often diagnosed in the first two years of a child’s life, but high-functioning individuals may not be diagnosed until much later in life.
Symptoms of autism occur in three main areas:
- Social interactions
- Verbal and nonverbal communication
- Repetitive or ritualistic behaviors
Adults with autism who are high functioning may have only mild challenges; others may have more severe symptoms, like impaired spoken language. No two people with ASD will have the same symptoms manifested in the same way. Regardless of manifestation or severity, ASD symptoms commonly interfere with everyday life. And as our understanding of those challenges improves, more people than ever are being diagnosed with ASD.
Symptoms of Autism Spectrum Disorder in Adults
Autism spectrum disorder (ASD) is typically a life-long condition, though early diagnosis and treatment can make a tremendous difference. Common symptoms of autism in adults include:

- During meetings, you find yourself making involuntary noises, like clearing your throat over and over.
