Neurodivergence refers to natural variations in brain function and cognition that differ from what society considers “typical” or neurotypical. The main types of neurodivergence include ADHD, autism spectrum disorder, dyslexia, dyspraxia, Tourette syndrome, obsessive-compulsive disorder (OCD), and several other conditions that affect how people process information, communicate, learn, and move through the world.

I was diagnosed with ADHD at 28, and honestly? I wish someone had explained neurodivergence this clearly back then. For years, I thought there was something fundamentally wrong with me because my brain worked differently. Now, after 11 years of working with neurodivergent clients, I understand that these differences aren’t deficits — they’re just variations in human neurology.

TL;DR:

  • Neurodivergence encompasses various conditions like ADHD, autism, dyslexia, and others that involve natural differences in brain function
  • These conditions often co-occur and share overlapping traits like sensory sensitivities and executive function challenges
  • Understanding your neurodivergent profile can lead to better self-advocacy, accommodations, and overall quality of life

What Does Neurodivergent Actually Mean?

The term “neurodivergent” was coined by autism activist Kassiane Asasumasu in the late 1990s as part of the broader neurodiversity movement. It describes people whose neurological development and functioning differ from societal expectations of “normal.”

Real talk: This isn’t about being broken or needing to be fixed. According to the National Institute of Mental Health, neurodevelopmental differences affect millions of people and represent natural variations in human brain development.

The neurodiversity paradigm suggests that conditions like ADHD, autism, and dyslexia are neurological differences rather than disorders that need to be cured. This doesn’t mean these conditions don’t come with challenges — they absolutely do. But it reframes the conversation from “what’s wrong with this person?” to “how can we create environments where this person can thrive?”

The Main Types of Neurodivergence

Here’s what the research says, translated into human: neurodivergence isn’t a single condition but rather an umbrella term covering various neurological differences.

ADHD (Attention-Deficit/Hyperactivity Disorder)

ADHD affects executive functions like attention regulation, impulse control, and working memory. Many of my clients describe it as having a race car brain with bicycle brakes. The three main presentations are inattentive, hyperactive-impulsive, and combined type.

Autism Spectrum Disorder (ASD)

Autism involves differences in social communication, sensory processing, and repetitive behaviors or intense interests. The “spectrum” part is crucial — autism presents very differently from person to person. Some autistic people are highly verbal and academically gifted, while others are non-speaking and need significant daily support.

Dyslexia

This learning difference primarily affects reading, spelling, and sometimes math. People with dyslexia often have strong visual-spatial skills and creative thinking abilities, but struggle with phonological processing — how sounds relate to letters and words.

Dyspraxia (Developmental Coordination Disorder)

Dyspraxia affects motor skills, coordination, and sometimes speech. It’s often called “clumsy child syndrome,” though this term doesn’t capture the full impact on daily functioning and self-esteem.

Tourette Syndrome

Characterized by involuntary tics — sudden, repetitive movements or vocalizations. Contrary to popular media portrayals, most people with Tourette’s don’t shout obscenities. Tics can be motor (blinking, shoulder shrugging) or vocal (throat clearing, humming).

Obsessive-Compulsive Disorder (OCD)

While debated whether OCD fits under the neurodivergent umbrella, many consider it part of the spectrum due to its neurobiological basis and impact on cognitive processing. OCD involves intrusive thoughts (obsessions) and repetitive behaviors (compulsions).

Understanding Co-occurring Conditions

If you just scrolled past everything to get here — hi, fellow ADHD brain. Here’s the important bit: neurodivergent conditions rarely travel alone.

Primary ConditionCommon Co-occurring ConditionsOverlap Rate
ADHDAutism, Anxiety, Depression, Dyslexia60-80%
AutismADHD, Anxiety, OCD, Sensory Processing70-90%
DyslexiaADHD, Dyspraxia, Dyscalculia40-60%
Tourette’sADHD, OCD, Anxiety85-90%

This overlap explains why getting an accurate diagnosis can take years. Many of my clients have been misdiagnosed multiple times before finding a clinician who understands neurodivergent presentations.

The phenomenon of masking in neurodivergence also complicates recognition. Many neurodivergent people, especially women and marginalized groups, learn to hide their differences to fit in, making their struggles less visible to others and sometimes even to themselves.

Recognizing Neurodivergent Traits

This is the part where most articles say ‘just use a checklist.’ We’re not doing that. Neurodivergence is complex and highly individual. However, there are some common themes I see in my practice:

Executive Function Challenges

  • Difficulty with planning, organization, and time management
  • Struggling to start or finish tasks
  • Problems with working memory (holding information in mind while using it)

Sensory Differences

  • Over- or under-responsiveness to lights, sounds, textures, or other sensory input
  • Seeking or avoiding certain sensory experiences
  • Feeling overwhelmed in busy or noisy environments

Social Communication Differences

  • Difficulty reading social cues or nonverbal communication
  • Preference for direct, explicit communication
  • Challenges with small talk or maintaining conversations

Intense Interests or Hyperfocus

  • Deep, passionate interests in specific topics
  • Ability to focus intensely on preferred activities
  • Difficulty shifting attention from interesting to necessary tasks

Processing Differences

  • Needing extra time to process information
  • Learning differently than peers
  • Strong abilities in some areas paired with challenges in others

Many neurodivergent individuals are also twice exceptional (2e), meaning they have both giftedness and learning differences. This combination can make recognition particularly challenging since strengths may mask struggles.

The Impact of Late Recognition

I see many adults who weren’t identified as neurodivergent during childhood. They often describe feeling like they were wearing a mask their entire lives, trying to fit into a neurotypical world that wasn’t designed for their brains.

Late recognition can lead to neurodivergent burnout, which looks different from typical stress or exhaustion. It’s a state of chronic overwhelm from trying to function in environments that don’t accommodate neurodivergent needs.

Some neurodivergent adults also experience pathological demand avoidance (PDA), particularly those on the autism spectrum. Understanding these patterns can be life-changing for people who’ve struggled with what seems like irrational resistance to everyday tasks.

Frequently Asked Questions

Q: Can you be neurodivergent without having a formal diagnosis? Yes, absolutely. Many people recognize themselves as neurodivergent before (or without) receiving a formal diagnosis. Self-identification is valid, especially considering barriers to assessment like cost, availability of knowledgeable clinicians, and historical bias in diagnostic criteria. While formal diagnosis can be helpful for accommodations and treatment, your lived experience matters regardless of paperwork.

Q: Do neurodivergent traits always cause problems, or can they be strengths? Neurodivergent traits exist on a spectrum and can be both challenging and beneficial, often depending on context. For example, ADHD hyperfocus can be a superpower in the right environment but problematic when you need to shift attention. Autistic attention to detail might be invaluable in quality control but overwhelming in social situations. The goal isn’t to eliminate these traits but to understand and work with them.

Q: Can trauma cause neurodivergence, or do they just look similar? This is a complex question I get often. Trauma can’t cause conditions like ADHD or autism, which are neurodevelopmental differences present from birth. However, trauma can mask or exacerbate neurodivergent traits, and neurodivergent people may be more vulnerable to trauma due to misunderstanding or rejection of their differences. Some trauma responses, like selective mutism in adults, can appear similar to neurodivergent traits but have different underlying causes.

Q: Is there a difference between being neurodivergent and having a mental health condition? Yes, though there’s overlap. Neurodivergence refers to natural variations in brain development and function, while mental health conditions typically involve distress or impairment that develops over time. However, many neurodivergent people also experience mental health challenges, often as a result of living in environments that don’t accommodate their needs. Additionally, some conditions like OCD straddle both categories.

When to Seek Professional Help

If you’re recognizing yourself in these descriptions, consider connecting with a mental health professional who specializes in neurodivergent adults. This is particularly important if you’re experiencing significant distress, struggling with daily functioning, or feeling like you’re constantly fighting against your own brain.

A knowledgeable clinician can help you understand your neurotype, develop strategies that work with (not against) your brain, and connect you with appropriate resources. They can also help distinguish between neurodivergent traits and mental health conditions that might benefit from treatment.

Remember, seeking understanding about your neurotype isn’t about finding excuses or limitations — it’s about gaining the self-knowledge you need to build a life that actually works for your brain.
