Neurodiversity: Minds that perceive the world before others do are not wrong—they are neurodiverse.
There’s a room full of voices. Chairs scrape against the floor with a sharp sound; someone laughs too loudly; a half-open window lets in a sliver of white light, almost sharp. Amid that little bit of everyday chaos,a child sits motionless, seemingly distracted.
He isn’t looking at the teacher, isn’t following along on the page, and doesn’t respond right away when called on. Yet he isn’t absent. He’s listening to everything: the hum of the lamp, the breath of the classmate next to him, the rustle of papers, the slightly irritated tone of the adult, the pressure of his shirt against his skin, the beat of his own heart beginning to race.
For him, the world doesn’t come filtered. It comes in its entirety.
Too close, too bright, too simultaneous. To a cursory glance, it may seem like inattention. To a clinical eye, however, it may appear for what it is: a different way of experiencing reality.
This is where we should start when addressing the topic of neurodiversity. Not with a label. Not with a list of symptoms. Not with a diagnosis handed down like a verdict. But with a person who feels, thinks, reacts, compensates, and protects themselves.
A person who, often long before being understood, has learned to feel like there’s something wrong with them.
In recent years, research has profoundly changed the way we view autism, ADHD, dyslexia, Tourette syndrome, dyscalculia, and other neurodevelopmental conditions. We can no longer afford to view them merely as deviations from a presumed norm.
The most recent literature invites us to adopt a broader, more rigorous, and also more humane perspective: the human brain does not exist in a single format. There are many cognitive architectures. Many sensory thresholds. Many modes of attention. Many learning styles.
Many ways of engaging in relationships, of tolerating the unexpected, of organizing time, of constructing meaning.
The concept of neurodiversity, which emerged in the late 1990s within the autism movement and was subsequently developed in international scientific, clinical, and cultural discourse, stems precisely from this insight: neurological variability is part of the human condition. Just as biodiversity exists in nature, so too does a plurality of mental functioning.
This does not mean denying suffering.
That would be a serious mistake, almost a form of superficiality in reverse. A neurodivergent person may possess great strengths and, at the same time, face profound difficulties. They may possess extraordinary sensitivity and suffer from the disorganization of daily life. They may have an extraordinary visual memory and break down in the face of an implicit social request.
They may pick up on details that others miss and be unable to tolerate the noise of a cafeteria, the bright lights of a supermarket, or the rigidity of a meeting.
Difference does not negate vulnerability. Vulnerability does not negate value.
Simon Baron-Cohen, in an editorial published in the Journal of Child Psychology and Psychiatry, defined neurodiversity as a revolutionary concept for autism and psychiatry. The reason is simple yet decisive: it forces us to distinguish between difference, disability, and illness. A neurocognitive trait can deviate from the average without being, in and of itself, a pathology.
It can, however, become disabling when the environment fails to recognize it, accept it, or support it.
It is in this gray area that much of real life plays out. Because often it is not just the neuroatypical brain that causes fatigue. It is the clash between that way of functioning and a world built for those who can handle noise, instantly interpret unspoken rules, switch seamlessly from one task to another, sit still for hours, make eye contact on command, grasp irony at just the right moment, respond quickly, don’t need breaks, and don’t get overwhelmed.
Elizabeth Pellicano and Jac den Houting have emphasized with great clarity that the science of autism can no longer be conceived solely “about” autistic people, but must also be built “with” them. It is a methodological shift, but also an ethical one. It means listening to subjective experience.
It means asking not only how to reduce a visible behavior, but what pain, what overload, what unspoken need lies behind that gesture.
A crisis is not always defiance. Sometimes it is a breakdown. Silence is not always withdrawal. Sometimes it is a defense mechanism. Distraction is not always a lack of interest. Sometimes it is an attentional system that latches onto stimuli that others do not even perceive.
Some people need intensive support throughout their lives; others receive a diagnosis in adulthood, after years of silent struggles, misunderstandings, and missed diagnoses.
A study published in 2025 in Nature Genetics by Aviya Litman, Natalie Sauerwald, and colleagues reinforced this perspective, showing how the clinical heterogeneity of autism may correspond to different genetic and molecular programs. Not a single line but a constellation. Not a compact block, but many trajectories.
Some emerge earlier, others later. Some are accompanied by marked language or developmental difficulties; others are intertwined with emotional vulnerabilities, anxiety, depression, and isolation.
This is an important scientific finding, but it is also a call for clinical caution. Every diagnosis is a map, not the territory. It helps us find our way, but it cannot replace listening to the person.
The same applies to ADHD. The comprehensive primer published in 2024 in Nature Reviews Disease Primers by Stephen Faraone, Samuele Cortese, Jan Buitelaar, and colleagues describes attention-deficit/hyperactivity disorder as a common condition but one with very diverse manifestations throughout the lifespan. In children, it may manifest as restlessness, impulsivity, and difficulty staying on task. In adults, it can turn into internal chaos, procrastination, attention instability, organizational difficulties, and a chronic sense of chasing after one’s own life without ever being able to grasp it.
Many adults with ADHD don’t say, “I can’t concentrate.” They say, “I’m tired of letting everyone down” .
They don’t say, “I forget things.” They say, “I feel like I’m living with a sense of guilt.”
They don’t say, “I’m impulsive.” They say, “I speak before I can stop myself, and then I spend hours berating myself.”
This is where clinical psychology must restore complexity. Because behind the symptom there is often a long history of shame. Children labeled as unmotivated, disorganized, unmanageable, too sensitive, too slow, too intense. Young people who have learned to compensate with anxiety.
Women who received a diagnosis after years of exhausting perfectionism. Men who have masked emotional dysregulation behind irritability, hypercontrol, or avoidance.
The issue of masking is central today. Laura Hull, William Mandy, and other researchers have studied “camouflaging”—that is, the set of strategies through which many people, particularly autistic girls and women, learn to hide their traits in order to appear socially adequate. They smile when they don’t understand the emotional code of the situation.
They mimic gestures and intonations. They mentally prepare their sentences before speaking. They suppress self-regulatory movements. They force themselves to make eye contact even when it becomes physically painful. From the outside, they seem to function normally. Inside, however, they are often worn down.
Masking can open doors in social, academic, and professional settings. But it can also leave a devastating sense of alienation. The person is only accepted when they are not fully themselves. It is a subtle form of loneliness: being among others, yet feeling as though one must constantly translate one’s own nature into a language that is not one’s mother tongue.
Meng-Chuan Lai and colleagues, in a systematic review and meta-analysis published in *The Lancet Psychiatry*, documented a high prevalence of associated psychiatric conditions in the autistic population, including anxiety and depression.
This finding should not be interpreted as a biological condemnation. Rather, it should prompt us to question the impact of chronic stress, exclusion, delayed diagnosis, sensory overload, and the lack of adequate accommodations.
In this context, neuroimmunomodulation offers an additional level of interpretation. The brain does not exist in isolation from the body. The nervous system, the immune system, the endocrine axis, and the environment are in constant communication, starting from the earliest stages of development.
In recent years, interest has grown in the role of microglia, cytokines, maternal immune activation, early-life stress, and low-grade inflammatory processes in neurodevelopmental trajectories. Caution is essential here. We cannot claim that inflammation “causes” autism or that the immune system “explains” ADHD.
That would be an undue oversimplification. We can, however, say that developmental biology is an integrated system, and that the organism registers, processes, and responds to genetic, environmental, immune, and relational conditions.
A 2024 review published in Seminars in Immunopathology by Mastenbroek and colleagues discussed the role of microglia in early brain development and the effects of maternal immune activation, calling for an understanding of the relationship between immunity, the intrauterine environment, and neurodevelopment without deterministic oversimplifications. That same year, a study in Translational Psychiatry by Isabel Schnorr and colleagues identified distinct inflammatory profiles in adults with ADHD, as well as an association between certain immune proteins and perceived chronic stress.
These are not diagnostic biomarkers, nor are they the sole explanations. However, they are signals consistent with a broader perspective: neuropsychological distress is never merely mental. It manifests through sleep, fatigue, muscle tension, gut health, the stress response, and the energy available to cope with the world.
In clinical practice, this is evident. There are people who are exhausted not because they are fragile, but because they have been living in a state of constant adaptation for years. Every day requires control, anticipation, and compensation. Every relationship can become a test. Every mistake seems to confirm an old belief: “I’m too much.” Too sensitive, too distracted, too slow, too rigid, too emotional, too different. Yet, very often, that “too much” is simply a mismeasurement.
Dyslexia illustrates this clearly. For a long time, it was mistaken for laziness, lack of effort, or inattention. Today we know that it has recognizable neurobiological foundations and involves networks related to phonological decoding, automation, and visual and linguistic processing. A child with dyslexia doesn’t read poorly because they don’t want to.
They read using a system that requires more energy to perform tasks that come automatically to others. Every line can be an uphill climb; every test, a public display of their struggle.
A 2024 study published in npj Science of Learning by Gaia Olivo, Jonas Persson, and Martina Hedenius explored brain plasticity in children with dyslexia through the implicit learning of sequences. This is an important finding because it reminds us that the neurodivergent brain is not static: it changes, learns, adapts, and develops compensatory strategies.
But it does so better when it is not weighed down by humiliation.
The key word, then, is environment. A context can disable or support, stifle or enable. It can force a person to expend all their energy just to appear normal, or it can free up resources for learning, creating, participating, and loving.
At school, this means not confusing speed with intelligence, the neatness of a notebook with the depth of thought, restlessness with a challenge, or looking away with a lack of respect. It means offering compensatory tools without turning them into humiliating concessions. It means protecting self-esteem alongside learning.
At work, it means rethinking spaces, schedules, noise levels, lighting, meetings, implicit instructions, and ambiguous communications. A neurodivergent mind can contribute so much when it finds the right conditions: precision, creativity, lateral thinking, a memory for details, the ability to immerse oneself, and sensitivity to inconsistencies. But no such potential emerges if all one’s energy is spent simply surviving the environment.
In relationships, an even more delicate revolution is needed: we must stop expecting affection to follow a single script. Some people show love by talking a lot, while others show it by staying close in silence. Some demonstrate care by remembering the smallest detail. Some feel deeply moved but don’t know how to express it in the expected way. Some need to withdraw—not because they lack love, but to keep from exploding.
Neurodiversity asks us to broaden the very concept of presence.
The risk in public debate is oscillating between two extremes: rigid medicalization and naive rhetoric that transforms every difference into a superpower, denying the real struggle of those who cannot sleep, organize themselves, work, tolerate social contact, or manage their own bodies when their nervous system is overwhelmed. The most serious position is also the most uncomfortable: recognizing the dignity of difference without erasing the need for care.
For those working in clinical psychology, neuroscience, and neuroimmunomodulation, this means observing the person in their entirety: not just behavior, but history; not just the diagnosis, but the adaptive burden; not just cognitive function, but the body that supports or betrays it. No diagnosis captures a whole person. It can help us understand, provide access to rights, tools, and relief. But it must not become a cage.
Perhaps the most urgent change is to stop asking people to become invisible in order to be accepted. They should not have to dim their own intensity, nor betray their own nervous system to appear polite, productive, intelligent, or likable.
A society that is truly inclusive does not tolerate difference as an exception. It adapts its spaces because it has realized that cognitive diversity is not a disruption of the human landscape. It is part of the landscape.
No city thrives on just one street.
And no mind should be forced to prove its worth by always walking the same one.
