Could You Have Symptoms of Autism in Adults?
Autism spectrum disorder (ASD) occurs in all age, racial, ethnic, and socioeconomic groups, according to the Centers for Disease Control1 . Autism is generally characterized by social and communication difficulties and by repetitive behaviors. Often, severe forms of ASD are diagnosed in the first two years of a child’s life, but high-functioning individuals may not be diagnosed until much later in life.
Signs of autism occur in three main areas:
- Social interactions
- Verbal and nonverbal communication
- Repetitive or ritualistic behaviors
Some autistic adults may exhibit symptoms that resemble attention deficit hyperactivity disorder (ADHD); others may have symptoms like impaired spoken language. Bottom line – adult autism can manifest in different ways. Regardless of manifestation or severity, ASD symptoms can pose challenges in everyday life. And as our understanding of those challenges improves, more people than ever are being diagnosed with ASD.
