Autism is increasingly being diagnosed in adulthood, often after years of misdiagnoses. Experts say many adults are first labeled with anxiety, depression, or ADHD before learning they are actually on the autism spectrum.
At the Kelberman Center, therapist Kaitlyn Holley explains that missing a diagnosis can leave people—and their families—confused and frustrated. A 2022 study found nearly a third of autistic U.S. adults weren’t diagnosed until after 18, with women and people of color especially underrecognized.
Late diagnosis can lead to untreated mental health struggles and job instability, as shown by Drexel research. Advocates say better diagnostic tools and awareness are needed to close the gap.
