How Do I Know If I Might Be Autistic? A Self-Discovery Guide for Adults

Introduction

Autism Spectrum Disorder (ASD) is often associated with childhood diagnosis, but many adults are discovering they may be autistic later in life. Whether due to subtle traits, masking behaviors, or a lack of awareness in earlier years, many individuals find themselves questioning their neurodiversity well into adulthood.

If you’ve ever wondered, “Am I autistic?” or felt different from those around you in ways that are difficult to explain, this guide will help you explore the signs, challenges, and strengths associated with autism. We’ll also touch on ADHD, which frequently coexists with autism and can add to the complexity of self-discovery.

Recognizing the Signs of Autism in Adulthood

Autism manifests differently in each person, but common traits can include:

1. Social and Communication Differences

  • Difficulty understanding social cues, sarcasm, or unspoken rules

  • Struggles with small talk and preferring deep, meaningful conversations

  • Feeling exhausted after social interactions or needing recovery time

  • Frequently misunderstanding others or feeling misunderstood

  • Difficulty expressing emotions in ways others expect

2. Sensory Sensitivities

  • Strong reactions to bright lights, loud noises, certain textures, or strong smells

  • Discomfort with certain fabrics or food textures

  • Heightened awareness of small sounds or movements others don’t notice

  • Seeking or avoiding sensory input (e.g., craving deep pressure or needing noise-canceling headphones)

3. Special Interests and Routines

  • Deep passion for specific topics, often becoming highly knowledgeable

  • Preference for routines and distress when they are disrupted

  • Hyperfocus on tasks, sometimes losing track of time

  • Struggling with transitions and unexpected changes

4. Masking and Camouflaging

  • Adapting behaviors to "fit in" or appear more neurotypical

  • Rehearsing conversations before they happen

  • Feeling exhausted from masking in social situations

  • Experiencing identity confusion due to years of adapting to others' expectations

Autism and ADHD: Overlapping Traits

Autism and ADHD often co-occur, and distinguishing between them can be challenging. While ADHD is characterized by inattention, impulsivity, and hyperactivity, autism is more related to social differences and sensory sensitivities. However, many individuals exhibit traits of both conditions.

Common overlapping traits include:

  • Hyperfocus on interests but difficulty with executive functioning

  • Sensory sensitivities impacting daily life

  • Social challenges, but for different reasons (e.g., impulsivity in ADHD vs. difficulty interpreting social cues in autism)

If you relate to both ADHD and autism traits, seeking professional guidance can help clarify your neurodivergence.

The Emotional Impact of Late Diagnosis

Discovering that you might be autistic as an adult can bring a mix of emotions. You might feel relief in understanding yourself better, grief over past struggles, or anxiety about what this means for your future. Some benefits of self-recognition include:

  • Self-acceptance: Understanding your brain works differently, not incorrectly

  • Community and connection: Finding others with similar experiences

  • Improved self-care: Identifying sensory needs and adapting environments accordingly

Should You Seek a Diagnosis?

Deciding whether to pursue a formal autism diagnosis is a personal choice. Some reasons to seek a professional evaluation include:

  • Access to workplace accommodations

  • Understanding coexisting conditions (e.g., ADHD, anxiety)

  • Validation and self-understanding

  • Access to therapy or support groups

However, some may opt for self-identification due to cost barriers, healthcare access, or personal preference. Whether formally diagnosed or not, recognizing your neurodivergence is valid.
