Perhaps you recognized yourself in an ADHD video on TikTok, “Masking? Social exhaustion? Executive dysfunction? Sounds just like me!” Then another question naturally follows, “Can I call myself neurodivergent if I don’t have a diagnosis?”
Unfortunately, this question is very complicated. There are whole online debates about whether self-diagnoses and “relating” to neurodivergent symptoms are enough for a person to be neurodivergent.
We’ll break down what is considered neurodivergent, how neurodivergence is diagnosed, and the pros/cons of both medically and self-diagnosed neurodivergency.
What Is Neurodivergence?
“Neurodivergent” means not neurotypical. So, it’s something that works differently from what is considered conventional. Let it be communication, learning, focus, emotional regulation, etc.
Being neurodivergent doesn’t mean being “sick” or “not normal.” Over 20% of the world population is neurodivergent [1]. This term works better when it’s considered a framework for understanding that brains do not all function in the same way.
Some people are neurodivergent just because of the gene lottery. The process that can make a person neurodivergent happens in the womb and during the infant phase, and it’s called neurogenesis, the birth of new neurons [2].
That’s how neurodivergent conditions, such as autism, ADHD, dyslexia, epilepsy, sensory processing disorder, etc., develop. Because these conditions often have the same origin, they may result in similar signs that you may be neurodivergent, which are also used for self-assessment:
- Sensory sensitivities
- Feeling intensely overloaded
- Difficulties with transitions
- Tics
- Problems with planning and organization
- Hyper-responsibility as compensation
- Problems with socialization
- Going nonverbal
These are common neurodivergent symptoms for all neurodivergent conditions. Of course, every neurodivergent will name you at least one unique symptom they have that you didn’t hear about.
That’s because neurodivergency is highly individual and also depends on how a person grew up, whether they are medicated, their culture, how functional they are, etc.
Do You Need a Diagnosis to Be Neurodivergent?
No, you don’t for a few reasons:
- “Neurodivergent” is not an official medical diagnosis; some people identify as neurodivergent without ever receiving a formal assessment.
- A person is neurodivergent before diagnosis as well. The diagnostic process can either confirm or overlook it. So, being diagnosed with something doesn’t automatically make you neurodivergent.
Self-diagnosis has become increasingly common. In workplace studies, 26.7% self-identified as neurodivergent vs. only 12.1% formally diagnosed, more than double [3].
People find and relate to neurodivergent traits through books, podcasts, social media, Reddit discussions, friends, or even after their own children receive diagnoses. Others simply cannot access professional evaluations due to barriers described above.
While you don’t need a diagnosis to begin understanding yourself, don’t underestimate the power of a formal diagnosis. An official assessment may provide access to workplace or school accommodations, medication, disability services, legal protections, and a sense of validation.
Self-Diagnosed Autism/ADHD: Pros and Cons
Self-diagnosis is one of the most debated topics in neurodivergent communities. Just get on Reddit and see for yourself the steamy debates where you agree with both sides at the same time.
Some people view it as a necessary response to inaccessible healthcare systems, while others worry about misinformation. The truth is always somewhere in the middle: self-diagnosis comes with both benefits and limitations. Read about them here.
Pros of Self-Diagnosis
- It can provide relief and self-understanding.
People stop viewing themselves as lazy or broken. According to research, cognitively self-diagnosis and medical diagnosis are the same, which means they influence behavior similarly [3].
- It allows people to self-accommodate sooner.
Instead of waiting months or years for an assessment, individuals may begin using strategies that support executive functioning and their unique sensory needs immediately.
- It reduces the possibility of bias or misdiagnoses.
Self-diagnosis is based on lived experience. There will be no external assumptions or biases that impact your self-identification.
- It empowers through community.
Social media, Reddit, books, and support groups empower individuals rather than keeping control in the medical authorities’ hands.
- It reduces stigma and returns a sense of control.
If neurodiversity is normal variation rather than a medical disorder, formal diagnosis shouldn’t be a requirement, Reddit users say. And it’s impossible to disagree.
Cons of Self-Diagnosis
At the same time, self-diagnosis is not without risks and should be approached thoughtfully.
- It’s not the most accurate.
The most popular self-assessment instrument for autism, RAADS-R, has only 3.03% chance of detecting the absence of ASD [4]. Public awareness leads to “noticing” difficulties, inflating self-scores
- It overlooks comorbid and differential diagnoses.
Mental health conditions are complex and require specialized knowledge. For example, an average neurodivergent individual might not know that 70% of neurodivergent diagnoses occur with anxiety.
- Social media can oversimplify complex conditions.
Relating to a few videos or symptom lists does not necessarily mean someone is neurodivergent. Usually, social media uses anecdotal evidence as a metric for self-diagnosis.
- Self-diagnosis rarely grants formal support.
Without official documentation, people may not qualify for accommodations, medication, disability services, or legal protections. Early interventions provided with an official diagnosis are crucial. For example, they decrease complications of autism by 50% [5].
Ultimately, self-diagnosis may be a valuable starting point, but it works best when paired with education, critical thinking, and openness to professional input when it is accessible and helpful.
