Adults can have autism, and for many people, this condition is not diagnosed until adulthood. If you are wondering whether you or someone you care about has autism, screening tests are available, and there are diagnostic criteria for adult autism.
Discuss your symptoms and how they are affecting your life with a healthcare professional. It’s important that you get professional support and guidance so you can receive an accurate diagnosis and start a treatment plan to help improve your well-being and quality of life.

Types of Autism Tests for Adults
Autism tests for adults can be used to screen for symptoms, while a formal medical autism diagnosis is based on specific criteria.
Self-Screening Tools
Many adults who think they have autism use self-screening tools. These widely available, free questionnaires can help you reflect on your symptoms and their effects on your life.
Self-screening tests can be a good way to prepare for a visit with a healthcare professional.
Popular self-screening autism tests for adults include:
You may have autism if you are experiencing distress in your life that prompted you to take a self-screening test. However, you might have another mental health condition, such as obsessive-compulsive personality disorder or depression.
No matter how your screening turns out, you can benefit from speaking with a professional. A healthcare professional can diagnose you and recommend management or treatment, if needed.
Professional Testing
Medical testing for autism may involve working with a neurologist, a psychologist, a psychiatrist, or a primary care provider. These professionals can consider your medical history, family history, and symptoms, as well as the results of a physical examination, to determine the next steps in your diagnostic process.
You may be referred to a specialist trained in diagnosing autism and conditions that may be confused with it.
Testing can include an interview to assess your symptoms, how long you have had symptoms, and whether you have symptoms of another mental health condition.
How Autism Is Diagnosed
Autism is diagnosed based on criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM) 5. No blood tests or imaging tests can verify or rule out a diagnosis of autism.
The features of autism presented in the DSM fall under five major categories:
- Challenges with interpersonal communication
- Unusual and intense interests
- Repetitive physical movements
- Strong responses to sensations
- Highly dependent on routine
Adult autism can be classified by the level of support needed:
- Level 0: You have autism but do not need any assistance to maintain a healthy quality of life.
- Level 1: You need some assistance maintaining focus, appropriate interactions, and effective communication with others. This may include therapy and adaptations from family, school, community, or work.
- Level 2: You need a lot of support, such as formal work or school accommodations or assistance from community resources, friends, and family. A healthcare professional should oversee your accommodations.
- Level 3: You cannot maintain independent living or self-care, even with care and support from family, a caregiver, or community resources.
Challenges in Diagnosing Adults
Autism diagnosis in adults can be challenging. The level of support needed varies widely. People who have increased support needs may be diagnosed during childhood and often continue to have obvious symptoms during adulthood.
People with less of a need for support might be harder to identify—and that can lead to a delay in diagnosis. Many people who need less support are good at masking the symptoms. While masking can help prevent some of the social consequences of autism, they might feel internal distress or use unhealthy coping strategies.
Signs and Symptoms of Autism in Adults
Each person’s symptoms of adult autism differ, but the main effects involve difficulties relating to others and a sense of disconnection from people.
Some signs and symptoms you may experience are:
- Frequent awkward pauses in conversations with other people
- Frequently feeling distressed or out of place when around other people
- Frequently misunderstanding what other people are trying to tell you, especially about emotions
- Having difficulty communicating your feelings to others
- Not understanding other people’s expectations if they are not explained very clearly
- Frequently being told that you are insensitive or that you have offended other people without intending to or without realizing
- High anxiety when you have to do something new
- Feeling distressed when your routine is disrupted
- Being told that you are too inflexible
- Being told that you go overboard with interests and hobbies
These signs and symptoms can lead to problems in your relationships with friends, family, your community, and people at work. You may feel that you do not belong or are an outsider, and autism may affect your ability to cooperate with others on shared projects at work.
The effects can include broken relationships, difficulty progressing to a higher position at work, and being excluded.
Parenting can be difficult if you have autism. Parents who have autism might be insensitive or blunt, often disregarding the emotional needs of their children. As a parent with autism, you might think of your kids only in terms of their objective accomplishments and milestones, without an appreciation of humor or fun.
Resources and Support
Living with the symptoms of autism can be stressful and distressing. You might feel that something is wrong, but you cannot put your finger on it. There is no reason to go through this alone. Autism is a recognized diagnosis, and you can get validation and treatment from healthcare professionals as well as from support groups and autism organizations.
People who have fewer support needs often learn to communicate effectively with others. This may be particularly important if they face family, relationship, or professional difficulties. A therapist can help you understand how to ask and respond to other people’s feelings and expectations and how to communicate yours.
Summary
Adults can have autism and may have a delay in recognition and diagnosis if they have a level of autism with fewer support needs. A healthcare professional can diagnose adult autism.
You can consider taking a screening test before you go in for your professional visit so that you can discuss the results of the screening test before you get a more definitive diagnosis.
Living with autism can be a challenge for adults, but resources are available. You might need special accommodations at work or school, or you may benefit from therapy and awareness about your condition.
