Though it’s very common to relate Autism Spectrum Disorder (ASD) to early childhood, many teens and adults have to live with undiagnosed autism in a world that can be overwhelming and confusing.
Diagnosing the signs of autism among older individuals is so important, as it opens the door for understanding, support, and accommodations that will substantially help in their lives.
How Teen Autism Differs From Childhood ASD
The symptoms of autism don’t disappear with age. Instead, they can evolve and grow harder to recognize.
Unlike young children, who may have overt developmental delays, the challenges of adolescence are added to the neurodiverse development of autistic teens. Social expectations become more complex, academic pressures rise, and changes like puberty can further heighten sensory sensitivities.
Younger children may demonstrate more apparent characteristics, such as delayed speech or repetitive play, but teens are more likely to camouflage their symptoms. Masking, or the concealing of autistic traits in social settings, can be incredibly exhausting and may lead to anxiety or depression.
Common Autism Traits in Adults
Recognizing autism in adults means learning to identify subtle signs that do not necessarily fit the traditional stereotypes.
Many adults have learned to adapt, but the core traits remain. These may include the following:
- Difficulty with Social Interactions: Difficulty understanding jokes, body language, or feeling uncomfortable in group settings.
- Strong Focus on Interests: A strong passion for specific topics, often to the point of expertise.
- Sensory Sensitivities: Overwhelmed by loud noises, bright lights, or crowded spaces.
- Routine-Oriented Behavior: Preference for predictable schedules and difficulty coping with sudden changes.
Adults also may describe feeling “different” their whole lives without understanding why. For some, discovering their autism later in life is both a relief and a challenge as they begin to process their experiences through a new lens.
Why Teens and Adults Go Undiagnosed
Many teens and adults are undiagnosed because the assessment for autism has historically focused on children, as has public awareness. This is indicated in the research on autism assessments, which explains how most tools were initially designed for young children.
Besides that, plenty of societal expectations are difficult to meet. Adults might blame their personality quirks or mental health conditions like anxiety and ADHD for the struggles they experience.
Meanwhile, autistic teens might instead internalize this pressure to fit in, avoiding behaviors that may raise concern in other people.
Supporting Older Individuals with Autism
Choosing the most fitting assessments, such as the language-based (CAPs) Clinical Assessment of Pragmatics or (SRS™-2) Social Responsiveness Scale, Second Edition, very well could be half the battle. After all, diagnosis of autism in teens and adults is the first step toward meaningful support.
Once autism is identified, interventions can be provided to enhance life skills, build social confidence, and accommodate sensory needs.
Support doesn’t have to be elaborate. Provide a safe space for teens to practice social interactions without judgment. Adults with ASD may benefit from workplace accommodations, such as flexible scheduling or sensory-friendly environments. Assessments like (ADOS®-2) Autism Diagnostic Observation Schedule, Second Edition and the behavior-based (ABAS®-3) Adaptive Behavior Assessment System, Third Edition can be helpful tools, too.
If you want to help teens and adults who fall somewhere on the autism spectrum, you can start by encouraging self-acceptance. Celebrate their strengths, and with any luck, they’ll follow suit.
A Path Toward Understanding
There is no age limit for autism. Identifying symptoms in teenagers and adults enables them to receive the necessary assistance to help them thrive.
Autism spectrum disorder (ASD) is a complex developmental condition involving persistent challenges with social communication, restricted interests and repetitive behavior. While autism is considered a lifelong condition, the need for services and supports because of these challenges varies among individuals with autism.
