The Fragmented Mirror: The Challenge of Late Diagnosis in Neurodivergences

The focus on neurodivergence—primarily Autism Spectrum Disorder (ASD) and ADHD—has been on childhood. We were taught to look for signs on the playground, but what about those who managed to navigate the system at the cost of invisible exhaustion?

Diagnosis in adulthood is not a trend; it is an act of historical justice for those who grew up feeling defective rather than different. I am one of them.

The Masking Phenomenon and the Cost of Adaptation

Many adults receive a diagnosis after years of perfecting masking (social camouflage). This is an adaptive response where the person involuntarily and unconsciously imitates neurotypical behaviors to fit in, suppressing their own sensory and cognitive needs. This is a neuroadaptive strategy.

While masking allows for work and social functioning, it comes at a high price:

• Chronic exhaustion (Burnout): A fatigue that is not relieved by sleeping, but rather by eliminating cognitive overload.

• Identity fragmentation: The feeling of not knowing who one is when no one is watching.

The Labyrinth of Comorbidities

One of the biggest obstacles to an accurate diagnosis is the presence of other mental health conditions that mask the underlying neurodivergent disorder. It's common for people to spend years in therapy treating symptoms without reaching the root cause, since the typical diagnostic criteria aren't readily apparent in the child's behavior. This increases their internal discomfort and their need to fit into the social world.

The diagnostic overlap

Neurodivergence is frequently accompanied by:

1. Anxiety and Depression: These are often secondary consequences of living in an environment designed for a different brain operating system.

2. Eating Disorders: These are especially linked to sensory rigidity or a need for control.

3. Personality Disorders: In women, autism is often mistakenly confused with Borderline Personality Disorder (BPD) due to emotional dysregulation.

The Difficulty of "Seeing" Neurodivergence

When a person has ADHD and Autism simultaneously (what some call AuDHD), the symptoms can cancel each other out or mask one another. While autism seeks routine and predictability, ADHD seeks novelty and impulsivity. This internal struggle creates a complex clinical profile that often confuses non-specialized healthcare professionals. Even more so when Au and Giftedness (GT) are present, the main characteristics of Autism, such as language delay, are masked by the high cognitive and reflective abilities associated with the GT diagnosis. Finally, at 36, I received the diagnosis that had made me feel strange my entire life and driven me to strive, through psychology, to heal in order to be "normal." ADHD, ABS, and AU1 was the diagnosis that freed me from the pressure of continuing to heal in order to resolve my social difficulties.

Reflection: "A late diagnosis doesn't change who you are, but it radically changes the story you tell yourself. It goes from being a story of inadequacy to one of resilience."

Conclusion: Towards a Radical Validation

Recognizing neurodivergence in adulthood requires looking beyond visible behaviors and understanding the internal experience. It's not about "what" the person does, but about "how much effort" it takes for them to do it.

For those of us who receive the diagnosis in our 30s, 40s, or 50s, the process is often bittersweet: there's a sense of loss for the help that didn't arrive in time, but also immense relief. Ultimately, understanding our neurological makeup is the only way to build a life that is not only functional, but also livable.

And the question I'm beginning to ask myself today is: will the rise in diagnoses lead us to reconfigure the concept of normality?

Is neurodivergence the new neurological normality after the technological advances in explaining this brain condition?
