The Neurodiversity Paradigm and Foundational Terms

Am I Neurodivergent? This question resonates with thousands of adults who have spent their lives feeling different, struggling with daily tasks that seem effortless to others, or masking their true selves to fit in. If you’re exploring whether you might have ADHD, autism, or both (AuDHD), you’ve come to the right place. This comprehensive guide will help you understand neurodiversity, recognize the signs, and navigate the path to diagnosis and self-acceptance.

What Is Neurodiversity? Understanding the Paradigm

The concept of neurodiversity fundamentally challenges traditional deficit-based perspectives of neurological differences. It asserts that differences in brain functions are natural variations within the human population—not deficits, disorders, or impairments that need to be fixed. The paradigm emphasizes accepting and celebrating diverse brain functions as part of what makes us human.

Key Terms You Need to Know

Neurodiversity: This concept suggests that brain differences, or neurotypes, are natural and valuable. They form part of human diversity, similar to variations in height or eye color. The term often refers to a group encompassing the full spectrum of brain differences, including both neurodivergent and neurotypical individuals.

Neurodivergent (ND): This term was coined by the neurodiversity movement as the opposite of “neurotypical.” It describes people whose brains develop or work differently from what is considered “standard.” It encompasses a range of neurotypes, including ADHD, autism spectrum disorder, dyslexia, dyspraxia, and more. It is explicitly a nonmedical term, though it is used widely in informal contexts within medical and research communities. Neurodivergence involves innate differences in cognitive processing that are lifelong and typically present from a young age.

Neurotypical (NT): This term describes people whose brain functions, information processing, and behaviors are considered standard. In functional terms, a neurotypical person’s uniqueness is not significant enough to meet formal diagnostic criteria for a disorder. The neurodiversity community uses this term to refer to those without neurological conditions like autism, ADHD, and dyslexia.

Neurodivergence vs. Mental Health: What’s the Difference?

One of the most common misconceptions is confusing neurodivergence with mental illness. ADHD and autism are neurological conditions—they stem from differences in brain structure and function. They are not mental illnesses, though neurodivergent individuals may experience co-occurring mental health challenges due to living in a world designed for neurotypical brains.

Neurodivergence is innate and lifelong. It doesn’t “resolve” with treatment, though support and accommodations can significantly improve quality of life. Mental health conditions, on the other hand, may develop at any point and can often be treated or managed to the point of remission.

Common Types of Neurodivergence

Neurodivergence encompasses various conditions and neurotypes, each with unique characteristics and strengths:

• ADHD (Attention-Deficit/Hyperactivity Disorder): Characterized by differences in attention regulation, impulse control, and executive function
• Autism Spectrum Disorder (ASD): Involves differences in social communication, sensory processing, and patterns of behavior and interests
• AuDHD: The co-occurrence of both autism and ADHD, affecting 50-70% of autistic individuals
• Dyslexia: Differences in language processing affecting reading and writing
• Dyspraxia: Differences in motor coordination and planning
• Dyscalculia: Differences in numerical and mathematical processing

Challenging Common Myths About Neurodivergence

The neurodiversity paradigm challenges pervasive misconceptions that cause harm to neurodivergent individuals:

Myth: Neurodiversity Is Just a Trendy Buzzword

Reality: Neurodiversity is a scientifically grounded concept that advocates for accepting neurological differences. Research consistently demonstrates that conditions like ADHD and autism involve measurable differences in brain structure, connectivity, and neurochemistry.

Myth: Neurodivergent People Are Disabled or “Less Than”

Reality: Neurodivergence is associated with unique strengths including creativity, innovation, hyperfocus, resilience, attention to detail, and specialized interests. Neurodivergent individuals often excel in fields like art, technology, engineering, and research. The challenges come not from the neurodivergence itself, but from societal barriers and lack of accommodations.

Myth: You Can Tell Someone Is Neurodivergent Just by Looking at Them

Reality: Neurodivergence is invisible. Many neurodivergent people, especially women and gender-diverse individuals, become experts at “masking” their traits to appear neurotypical. This masking comes at a significant cost to mental health and wellbeing.

Understanding ADHD in Adults

Adult ADHD often looks different from childhood presentations. Many adults have developed coping mechanisms that mask their symptoms, leading to years or decades of undiagnosed struggles. ADHD in adults manifests through difficulties with executive function, time management, emotional regulation, and maintaining attention on tasks that aren’t inherently interesting.

Common ADHD Characteristics in Adults

• Difficulty starting or completing tasks
• Time blindness and chronic lateness
• Emotional dysregulation and rejection sensitivity
• Hyperfocus on interesting activities
• Executive dysfunction affecting daily life
• Impulsivity in speech, decisions, or actions
• Difficulty with organization and prioritization
• Restlessness or internal sense of being “driven by a motor”

Many adults with ADHD describe feeling like they’re constantly failing at “adulting,” despite being intelligent and capable. This disconnect between ability and performance often leads to shame, anxiety, and depression.

Understanding Autism Spectrum Disorder in Adults

Autism in adults is often misunderstood and underdiagnosed, especially in women and individuals who don’t fit the stereotypical presentation. Autism involves differences in social communication, sensory processing, and information processing. Autistic adults may have learned to mask their autistic traits through years of observing and mimicking neurotypical behavior.

Common Autism Characteristics in Adults

• Differences in social communication and understanding social cues
• Sensory sensitivities or seeking behaviors
• Strong need for routine and predictability
• Deep, focused interests in specific topics
• Difficulty with changes in plans or environment
• Preference for direct, literal communication
• Social exhaustion after interactions
• Stimming behaviors for regulation
• Different ways of processing emotions

Many autistic adults describe feeling like they’re “from another planet” or constantly translating between their natural way of being and neurotypical expectations. This chronic mismatch can lead to burnout, mental health challenges, and loss of identity.

The Gendered Experience: Late Diagnosis in Women

Women and gender-diverse individuals are significantly more likely to receive late diagnoses of ADHD and autism. This diagnostic gap stems from multiple factors including male-biased diagnostic criteria, gendered expectations, and superior masking abilities developed through socialization.

Why Women Are Diagnosed Later

Many late-diagnosed women felt they were missed or dismissed because their presentation didn’t fit male-biased diagnostic criteria or gendered stereotypes. Girls and women are often socialized to be more aware of social expectations and better at masking their neurodivergent traits. This creates an “invisibility cloak” that hides their struggles while causing significant internal distress.

The pressure to meet neurotypical femininity standards compounds the challenges. Women often mask not just their neurodivergence but also perform expected femininity—being accommodating, socially skilled, and emotionally attuned. This double masking leads to burnout, mental health difficulties like depression and anxiety, and delayed diagnosis.

Epistemic Injustice and Empowerment

Not knowing they were neurodivergent constituted epistemic injustice—lacking the knowledge necessary to understand themselves. Receiving a diagnosis empowers women to overcome this injustice, adopt a clearer understanding of their identity, and challenge gendered inequalities related to neurodiversity.

The Life-Changing Impact of Late Diagnosis

For adults, receiving a late diagnosis of autism or ADHD (or both, known as AuDHD) can be profoundly transformative. The neurodiversity paradigm provides a crucial framework for navigating this transition from confusion and self-blame to understanding and acceptance.

Validation and Relief

A diagnosis provides external explanation for lifelong struggles and internal confusion that were often misattributed to personal flaws, laziness, or inadequacy. Diagnosis serves as external validation, relieving self-blame and feelings of shame and guilt. Many adults describe diagnosis as “finally having the missing puzzle piece” that explains their entire life experience.

Reframing Identity

Diagnosis enables adults to experience an identity shift towards one that is autistic or neurodivergent. It allows them to view past life events through a new lens, moving away from a negative self-concept (feeling like “a failure” or “faulty”) toward self-acceptance and developing a clearer identity. This process of reauthoring their lives requires continuous effort due to lasting effects of accumulative trauma from living undiagnosed.

Understanding Masking

Masking, especially before diagnosis, can cause loss of sense of self, self-harm, mental and physical exhaustion, and increased vulnerability to abuse. These issues highlight the profound negative consequences of living in a world intolerant of autistic ways of being. Understanding masking helps newly diagnosed adults recognize the enormous effort they’ve been expending just to appear “normal.”

Life After Diagnosis: Support and Next Steps

Receiving a diagnosis is just the beginning of your neurodivergent journey. What comes next is learning to live authentically, finding support, and building a life that works with your brain rather than against it.

Finding Your Community

Connecting with other neurodivergent adults can be incredibly validating. Online communities, local support groups, and neurodiversity-affirming spaces provide opportunities to share experiences, learn strategies, and feel less alone.

Accommodations and Support

Whether at work, home, or in relationships, identifying and implementing accommodations can dramatically improve your quality of life. This might include flexible work arrangements, sensory accommodations, organizational systems, or communication strategies.

Therapy and Professional Support

Working with neurodiversity-affirming therapists who understand the neurodiversity paradigm can help process diagnosis, address co-occurring mental health challenges, and develop strategies for thriving as a neurodivergent person.

Frequently Asked Questions About Neurodivergence

How do I know if I’m neurodivergent?

If you consistently struggle with tasks that seem easy for others, feel like you’re “masking” or pretending to fit in, have sensory sensitivities, or notice patterns of difficulty with executive function, social communication, or emotional regulation, you might be neurodivergent. The only way to know for certain is through professional assessment.

Can you be both autistic and have ADHD?

Yes! This is called AuDHD, and research suggests that 50-70% of autistic individuals also have ADHD. The combination creates unique challenges and strengths that differ from having either condition alone.

Is it worth getting diagnosed as an adult?

Many adults find diagnosis profoundly validating and life-changing. It provides explanation for lifelong struggles, access to accommodations and support, and permission to stop masking and live authentically. However, the decision is personal and depends on your individual circumstances, goals, and access to affirming assessment.

What is masking, and why is it harmful?

Masking is consciously or unconsciously hiding neurodivergent traits to appear neurotypical. It’s harmful because it leads to exhaustion, burnout, loss of identity, mental health challenges, and prevents you from accessing support and accommodations you need.

Can neurodivergence be cured or treated?

Neurodivergence is not a disease, so it doesn’t need to be “cured.” It’s a natural variation in how brains work. Support, accommodations, and sometimes medication can help manage challenges and improve quality of life, but the goal is thriving as your authentic neurodivergent self, not becoming neurotypical.

Your Neurodivergent Journey Starts Here

Understanding neurodiversity and exploring whether you might be neurodivergent is a journey of self-discovery and acceptance. Whether you’re just beginning to question if you’re neurodivergent, in the process of seeking diagnosis, or already diagnosed and learning to live authentically, remember: your brain is not broken, it’s just different.

The neurodiversity paradigm empowers you to see your differences not as deficits but as natural variations that come with unique strengths and perspectives. By understanding your neurodivergence, finding community, and accessing appropriate support, you can build a life that honors who you truly are.
