How Adults Can Get Diagnosed With Autism

Many adults living with autism go undiagnosed for years. They may struggle with social interactions, anxiety, or sensory sensitivities but never connect those challenges to neurodivergence. For some, the turning point comes after a child’s diagnosis. For others, it’s ongoing burnout, repeated misunderstandings, or simply the desire to better understand themselves.

If you suspect you may be on the autism spectrum, it’s never too late to seek clarity. Getting tested and diagnosed as an adult can be empowering and validating and it opens the door to meaningful support.

How Autism Testing Works for Adults

Unlike physical conditions that can be detected with a blood test, autism spectrum disorder (ASD) is diagnosed based on behavior and developmental history. That said, there are structured tools and criteria that professionals use to assess whether someone meets the diagnostic standards for autism.

Here are the most common ways autism is screened and diagnosed in adults:

Self-Screening Tools

Before speaking with a professional, many adults begin with a self-assessment. These free online questionnaires are not diagnostic tools, but they can help you reflect on patterns in your thinking, communication style, and relationships. Common self-tests include:

• Autism Spectrum Quotient (AQ) – 50-item version: Assesses social preferences, communication habits, and focus on patterns or routines

• AQ – 10-item version: A faster, shorter version for quick screening

• Camouflaging Autistic Traits Questionnaire: Helps identify how much someone masks or hides their autistic traits in social situations

If you score high or feel that the questions resonate, it’s worth bringing your results to a qualified healthcare provider for a full evaluation.

Professional Testing and Evaluation

A formal autism diagnosis for adults typically involves a psychologist, psychiatrist, neurologist, or developmental specialist. During the evaluation, they may:

• Review your personal and family medical history

• Conduct interviews or questionnaires that focus on social behaviors, communication challenges, sensory sensitivities, and repetitive behaviors

• Explore co-occurring conditions, such as anxiety, depression, or ADHD

• Evaluate how your traits have affected various areas of your life (e.g., work, relationships, daily routines)

Importantly, an accurate diagnosis doesn’t happen in a single step it’s a thoughtful process that considers how long you’ve experienced symptoms, how much they impact your life, and what supports may help you thrive.

Diagnostic Criteria for Autism in Adults

The American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM-5) outlines specific criteria for diagnosing autism. To meet these standards, an adult must show persistent challenges in areas such as:

• Social communication and interaction, including difficulty with conversations, understanding body language, or forming relationships

• Restricted or repetitive behaviors, like intense interests, strict routines, or repetitive movements

• Sensory sensitivities, such as being overwhelmed by noise, light, or touch

• Difficulty adapting to change, often accompanied by significant stress or anxiety

Autism is also classified by support levels:

• Level 1: Requires some support with social skills, transitions, or emotional regulation

• Level 2: Needs more substantial assistance, including structured support in daily life

• Level 3: Requires significant, often full-time, support to manage daily activities and communication

Why Diagnosing Autism in Adults Can Be Challenging

Many adults with autism especially those with Level 1 support needs have learned to “mask” their symptoms. This means mimicking social behaviors, suppressing stimming (repetitive movements), or scripting conversations. While masking can help individuals fit into social settings, it often leads to burnout, anxiety, and a deep sense of disconnection.

Women and Autism: A Closer Look

Research suggests that women are more likely to mask their autistic traits, which may explain why they are often underdiagnosed. They may appear socially “successful” while privately feeling exhausted, misunderstood, or emotionally overwhelmed.

Common Signs of Autism in Adults

Everyone’s experience with autism is different, but some shared signs include:

• Difficulty maintaining conversations or understanding social cues

• Feeling like an outsider in group settings

• Intense focus on specific interests or hobbies

• High anxiety when routines are disrupted

• Being labeled as “insensitive” or “blunt”

• Struggles with emotional expression or reading others’ feelings

• Challenges at work, including with teamwork or task-switching

• Feeling overwhelmed in loud or busy environments

These signs may interfere with relationships, parenting, and career progression—yet many people go years without recognizing the pattern or accessing help.

Parenting as an Autistic Adult

Being a parent while on the spectrum can come with unique challenges. Some autistic parents may struggle to pick up on emotional cues or balance flexibility with routine. That said, many bring exceptional strengths to parenting such as honesty, creativity, and strong problem-solving skills. With the right support, parenting with autism can be both possible and fulfilling.

How to Get Support

If you think you may have autism, the first step is reaching out to a healthcare provider for an initial conversation. From there, you may be referred to a psychologist or neurodevelopmental specialist for formal testing.

Whether or not you receive a diagnosis, therapy can help you improve communication, manage anxiety, and navigate life transitions. You can also seek community through:

• Autism support groups (in person or online)

• Local and national autism organizations

• Workplace accommodations or coaching

Getting Diagnosed Isn’t About Labels It’s About Understanding

Autism isn’t something to “fix.” It’s a neurodevelopmental difference that shapes how you experience the world. For many adults, a diagnosis offers clarity, relief, and a chance to finally be understood for who they are, not who they were expected to be.
