What Is Neurodivergence? Terms, Numbers and the Situation in Germany

Neurodivergent means that a person's neurological development differs markedly from what a society treats as typical. It covers autism, ADHD, dyslexia, dyscalculia and other variations. Neurodivergence is not a medical diagnosis and not an illness. It is an umbrella term that came out of autistic self-advocacy.

The word has moved from specialist circles into everyday use over the past few years, and misunderstandings have travelled with it. This article explains the terms, puts the numbers in context and says plainly what is still contested.

Please note: This article provides general information. It is not a diagnosis and does not replace medical or psychotherapeutic assessment.

Neurodiversity, neurodivergence, neurotypical: what the terms mean

The three words get used interchangeably. They mean different things.

The most common error is using "neurodiverse" to describe one person. It does not work. Diversity presupposes a group. An individual can diverge, but cannot be diverse on their own. The glossary published by Diversity Arts Culture Berlin makes the same point and notes that German has no binding definition so far.

Where the term comes from, and why the popular version is wrong

Almost everywhere you will read the same account: the Australian sociologist Judy Singer coined "neurodiversity" in 1998, and the journalist Harvey Blume popularised it in The Atlantic.

That account was corrected in 2024 in the journal Autism. Six autistic scholars, among them Monique Botha, Robert Chapman and Steven Kapp, went back through the sources. Their finding: the concept was developed collectively, primarily on the "Independent Living" (InLv) mailing list in the mid-1990s. Martijn Dekker, who founded that list, has documented a discussion from 1996 that already spoke of the "neurological diversity of people". That predates any involvement by Singer or Blume.

The authors trace the misattribution largely to Steve Silberman's 2015 bestseller "NeuroTribes". Their conclusion is blunt: to keep crediting the coinage to a single individual would be to erase neurodivergent people from their own history.

The word "neurodivergent" has a different origin. The American activist Kassiane Asasumasu coined it around the year 2000, explicitly as a term of inclusion. In her own words, it is "a term of inclusion NOT a term of exclusion", and she expressly included acquired conditions and mental illness.

The founding text of the movement is generally taken to be the 1993 essay "Don't Mourn for Us" by Jim Sinclair. Its core message, in paraphrase: grieve for your own lost dreams if you must, but do not grieve for us, because we are alive and real.

Which conditions count as neurodivergence?

There is no official, closed list. A useful split is between a broadly accepted core and contested edges.

Broadly accepted: clinical diagnoses under ICD-11 and DSM-5

On the individual figures: for ADHD in children the reference is the meta-analysis by Polanczyk and colleagues at 5.29% across 102 studies, and for adults a meta-analysis reporting 2.5% (confidence interval 2.1 to 3.1). For Germany, the KiGGS study run by the Robert Koch Institute reports 4.4% among 3- to 17-year-olds in its second wave, 6.5% for boys and 2.3% for girls. The frequently quoted 5% comes from the 2003 to 2006 baseline and is out of date.

For dyslexia the German S3 guideline states "roughly 3 to 8%". Worldwide, a 2022 meta-analysis arrives at 7.10% among primary school children, with a marked sex difference: 9.22% in boys, 4.66% in girls. For dyscalculia the ratio between the sexes is roughly balanced; Shalev and Gross-Tsur report 5 to 6%, while the German guideline gives a wider 2 to 8%.

For dyspraxia, a 2024 meta-analysis pools 5% worldwide but only 2% for Europe. For Tourette's, the estimates from Knight 2012 (0.77%), Scharf 2015 and Jafari 2022 overlap so heavily that a single point estimate would claim more precision than exists. For developmental language disorder, Norbury 2016 found 7.58% among 4- to 5-year-olds, roughly two children per classroom.

Contested: traits many people include and the field does not classify consistently

For several of these the studies openly contradict each other, and saying so is more accurate than smoothing the numbers. Prosopagnosia was long thought to affect about 2.5%, based on a German self-report study from 2006. A 2023 reassessment using objective tests on 3,116 unselected people arrived at 0.93%. For misophonia, a first representative German survey found 5.0% on one questionnaire and 5.9% on another, but only 2.2% met both sets of criteria; a second German study reported 2.1%. For aphantasia, the measurement instrument simply drives the result.

For alexithymia, the classic Finnish study by Salminen 1999 reports 13% in the general population, and research in Germany found 10%. In autistic samples the proportion is considerably higher, with a 2019 meta-analysis arriving at around 50%.

Mental illness: the boundary that is rarely drawn cleanly

Whether depression, anxiety disorders, bipolar disorder, OCD or PTSD belong under neurodivergence is contested. Under Kassiane Asasumasu's original broad definition: yes. In narrower everyday use, "neurodivergent" often means only autism, ADHD and the learning disorders.

For a general reader, one distinction matters more than the terminology. Depression and anxiety disorders are understood as mental illnesses and frequently run in episodes. Autism and ADHD are enduring developmental characteristics that last a lifetime. The difference lies in duration, not in treatability. Both are treatable, with different goals: for an illness the aim is remission, for an enduring characteristic it is co-occurring conditions, strain and adjustments. ADHD additionally responds well to medication.

The two frequently occur together. Autistic people and people with ADHD develop depression and anxiety disorders considerably more often than the general population. A depression remains a depression even when it meets an enduring neurotype, and it can be treated without waiting for an assessment to conclude.

The debate about acquired forms after traumatic brain injury or stroke, or in dementia, is equally open. Asasumasu explicitly included them. Narrower usage tends to leave them out, because neurodivergence is understood there as innate and identity-forming.

How many people are neurodivergent?

There is no reliable figure for the umbrella term, because the list itself is not closed. There are figures for individual conditions, and autism in particular repays a closer look.

You will find two very different numbers in the media. Both are correct. They are not measuring the same thing.

The gap looks dramatic but has little to do with biology. The WHO estimates worldwide across all ages, while the US programme actively searches school and health records for a single age group in selected regions. How much the method drives the result is visible inside that survey itself: from 9.7 per 1,000 children in Laredo, Texas, to 53.1 in California. That is a factor of more than five between two regions of the same country in the same year.

Two notes, because both figures are widely misquoted. Since its fact sheet was revised in September 2025, the WHO no longer says "1 in 100 children" but 1 in 127 people. And the much-cited CDC figure of "1 in 36" comes from surveillance year 2020; since April 2025 the figure is 1 in 31.

For Germany, around 1% is the usual estimate. The Autismusstiftung puts it at 1 to 2% and attributes the increase since the 1980s to better recognition.

Twin studies support the view that rising diagnosis rates mainly reflect better recognition. A 2023 study found the heritability of ADHD stable at 64 to 65% across the observation period even as diagnoses increased. The causes have not changed. Our attention to them has.

Three common misconceptions

"High sensitivity is a form of neurodivergence"

High sensitivity goes back to the psychologist Elaine Aron and is measured with a questionnaire. Aron herself stresses that it is a normal variation in temperament rather than a disorder, and puts it at 20 to 30% of the population.

The criticism deserves to be taken seriously. The questionnaire demonstrably does not measure a single unified construct but breaks into several factors, and it separates poorly from anxiety, neuroticism and introversion. "Sensory processing disorder" is a recognised diagnosis in neither ICD nor DSM.

Describing high sensitivity as a temperament trait is defensible. Putting it on a level with autism or ADHD is not.

"You can see neurodivergence on a brain scan"

This is the most persistent myth, and it has been studied carefully. A 2022 paper in Nature analysed around 50,000 imaging datasets. The finding: associations between brain measures and behaviour are very small. Across all associations examined in a sample of 3,928 people, the median correlation was about 0.01. Smaller studies had previously reported values above 0.2. The median sample size of earlier imaging studies was around 25 people.

The authors conclude that reliable findings require samples of several thousand. A plain-language summary is available. Other research groups argue that better methods could work with more moderate samples. The debate is open.

In practical terms: there is no blood test, no brain scan and no biomarker that identifies neurodivergence. Anyone offering one is promising more than the research supports. Assessment rests on structured interviews, observation and developmental history.

"A strong suspicion is as good as a diagnosis"

A survey by the Ohio State University Wexner Medical Center of 1,006 adults found that roughly one in four suspects they have ADHD, while only 13% have raised it with a doctor. By comparison, according to the US health authorities, about 6% of US adults had a current ADHD diagnosis, or one in 16.

None of this is an argument against self-observation. Many adults first encounter a question that explains their life through a post online, and given the waiting times, self-identification is understandable.

Part of the gap does trace back to social media. An analysis of ADHD videos on TikTok classified just over half as misleading. A review of 27 studies and more than 5,000 posts found around 35% misinformation on TikTok against roughly 26% across all platforms studied. An experiment at Syracuse University shows the effect: exposure to such content leaves people knowing less while feeling more certain.

It is an argument for taking the suspicion seriously enough to have it assessed as soon as that is possible.

Who can diagnose in Germany?

Only qualified professionals may make a diagnosis:

• Specialists in psychiatry and psychotherapy, in child and adolescent psychiatry, or in the combined German neurology-and-psychiatry qualification (Nervenheilkunde)
• Licensed psychotherapists, including those for children and adolescents and those licensed under the 2020 reform
• Specialist outpatient clinics and autism centres
• Social paediatric centres, often the fastest route for children

For autism, ADOS-2 as an observation instrument and ADI-R as a developmental interview are the standard. For ADHD, assessment follows a structured guideline-based process. Both take several hours and draw on a person's whole life history. The national association autismus Deutschland e.V. describes the process in detail and notes that private-pay assessments are increasingly not officially recognised. Statutory health insurance covers assessment at accredited providers.

Online tests do not replace a diagnosis. Questionnaires on the internet can be a reason to book an appointment. They are not a result. That includes self-tests that output a percentage score.

Waiting times, guidelines and disability status in Germany

The gap in provision is real

For adults seeking an autism assessment, 18 to 24 months is the norm, and many waiting lists are closed. One specialist clinic in Berlin receives over 1,300 enquiries a month and can accept 35 to 40 of them. Only around 40% of those eventually assessed receive an autism diagnosis. Among the rest, personality disorders, social phobia, ADHD and other conditions are found, which are equally something to work with. An assessment rarely ends with nothing. In the other direction it is documented that autistic women are diagnosed with a personality disorder for years before the autism is recognised. For children, the Autismus-Ratgeber puts waiting times at 6 to 12 months.

A waiting list is no reason to put everything else on hold. Four things can be done beforehand. First, join several waiting lists at once, which is permitted and common. Second, gather school reports, nursery records and relatives' recollections now. Assessment draws on them later, and the developmental interview usually requires someone who knew you as a child. Third, depression, anxiety or exhaustion can be treated without waiting for an assessment to conclude. Fourth, a degree of disability is determined by impairment in daily life, not by a particular diagnosis.

The pattern may be familiar from psychotherapy. We have written separately about why provision there is under comparable strain: 142 days waiting for therapy.

All the relevant German guidelines have currently lapsed

This is a finding that rarely gets mentioned. As of August 2026, the three central German S3 guidelines stand as follows:

A lapsed guideline does not mean nobody is working properly any more. It means the binding common standard is missing while diagnosis rates rise. The current status is tracked by the Zentrales ADHS-Netz, with an overview also kept by the professional body DGKJP.

Degree of disability and workplace rights

Under the German assessment rules, autism is classified under "pervasive developmental disorders". What counts is always the impairment in daily life, never the diagnosis on its own.

From a degree of 50 onwards, formal severe-disability status applies, bringing enhanced protection against dismissal and five additional working days of leave in a five-day week. From 30 onwards, equivalent status can be granted where without it a suitable job cannot be obtained or kept. The tax allowance under § 33b EStG is separate and already starts at a degree of 20. The degree of disability is determined by the regional disability assessment office (Versorgungsamt); equivalent status is applied for at the Federal Employment Agency (Agentur für Arbeit). sozialrat.org offers an accessible overview. ADHD is not assessed under the same heading but under the general rules for mental disorders.

There is no obligation to disclose to an employer. A diagnosis is private information. Those who do disclose can claim workplace adjustments and assistive technology. The integration office must approve any dismissal of an employee with severe-disability or equivalent status, once the employment has lasted more than six months. Anyone who never disclosed must do so within three weeks of receiving a dismissal, otherwise the protection does not apply.

What remains contested among professionals

Does the term split the spectrum? In 2022 the Lancet Commission introduced the explicitly non-diagnostic term "profound autism" for people aged eight and over with very high support needs. The aim was visibility for a group largely absent from public debate. Self-advocacy organisations objected sharply: the term divides and stigmatises, and autistic voices were insufficiently involved. The argument runs within the community too. The tension is unresolved: the worry that people with high support needs become invisible, against the worry that a new dividing line stigmatises.

Are women overlooked? Autism is diagnosed more often in men. Whether that has biological reasons or reflects diagnostic criteria shaped around men is open. One line of argument points to compensating behaviour that masks traits and delays diagnosis; a review article summarises the state of research. Critics warn against treating the "female phenotype" as established.

Is it "autistic person" or "person with autism"? In English-speaking countries most autistic adults prefer the first form; a global survey found around 80% favouring "autistic person". A Dutch study of 1,026 participants found the opposite: 68.3% there preferred the second. Both results are sound. They measure different language communities. No data exists for German. The Autismus-Forschungs-Kooperation recommends neutral wording such as "person on the autism spectrum" and advises against functioning labels such as "high-functioning". The most workable rule remains to ask, then use the person's own words.

AuDHD is not an official diagnosis but shorthand for autism and ADHD occurring together. The dual diagnosis has only been permitted since DSM-5 in 2013. The overlap is substantial, though the published estimates vary widely.

Where to find support in Germany

If you want to start an assessment, the usual order is this: ask your GP for a referral, use the directories of autismus Deutschland or ADHS Deutschland to find assessment centres in your region, join several waiting lists at once, and bring in the EUTB as free support alongside. For children the route runs through the paediatrician to a social paediatric centre.

These organisations advise free of charge or refer you onwards:

Plenty of everyday support is not treatment at all: managing sensory input, ear protection in loud environments, a dependable daily structure, written rather than spoken agreements, breaks taken before exhaustion rather than after. The principle is to adjust the environment rather than the person.

Separate from that is everything belonging in medical or psychotherapeutic hands: assessment, medication, psychotherapy, occupational therapy and speech therapy. Psychological counselling, including the forms available outside the healthcare system, is neither psychotherapy nor assessment. Our article on psychological counselling versus psychotherapy sets out where the line runs, and the cost comparison covers what assessment and treatment cost in Germany.

Frequently asked questions

What does neurodivergent mean in simple terms?

Neurodivergent means that a person's neurological development differs markedly from what is treated as typical. The term covers autism, ADHD, dyslexia and dyscalculia among others. It is not a diagnosis but an umbrella term from self-advocacy.

What is the difference between neurodiversity and neurodivergence?

Neurodiversity describes a group, namely the variety of all brains in a population. Neurodivergence describes an individual whose neurological functioning differs from the norm. A person can be neurodivergent, but cannot be "neurodiverse" on their own.

What counts as neurodivergence?

Broadly accepted are autism, ADHD, dyslexia, dyscalculia, dyspraxia, Tourette's and developmental language disorder. Contested are high sensitivity, misophonia, aphantasia and alexithymia, along with the question of whether mental illness and acquired conditions belong. There is no official list.

Is high sensitivity a neurodivergence?

That is contested. High sensitivity is not a recognised diagnosis in ICD or DSM but a temperament trait. The underlying questionnaire does not measure a single unified construct, and it separates poorly from anxiety and introversion. As a self-description the term is widespread; scientifically it stands on weaker ground than autism or ADHD.

Can you be neurodivergent without a diagnosis?

Yes. Neurodivergence is not a diagnostic term, and many adults describe themselves this way without ever having been assessed. A self-description does not replace assessment, though. Entitlements such as workplace adjustments, formal disability status or treatment all require a diagnosis.

Is neurodivergent the same as disabled?

No. "Disability" is a legal category tied to impairment of participation in daily life and granted through a formal assessment procedure. Neurodivergence is a description, not a status. Some neurodivergent people hold recognised disability status; many do not.

Is neurodivergence an illness?

No. Individual conditions are clinical diagnoses; the umbrella term is not an illness. The neurodiversity paradigm treats disability as arising from the interaction between a person and an environment not built for them. Clinical diagnoses, by contrast, require significant impairment. That tension has not been resolved.

How many people are neurodivergent?

There is no reliable figure for the umbrella term, because the list is not closed. For individual conditions there is: autism affects around 1 in 127 people worldwide, ADHD around 5% of children and 2.5% of adults, dyslexia 3 to 8% of children. Circulating totals such as "15 to 20% of the population" come from adding up overlapping estimates and are not evidenced.

Who can diagnose ADHD or autism in Germany?

Specialists in psychiatry and psychotherapy, in child and adolescent psychiatry or in the combined neurology-and-psychiatry qualification, licensed psychotherapists, specialist outpatient clinics and autism centres, and for children social paediatric centres. Online tests and self-report questionnaires are not assessment.

How long is the wait for an autism diagnosis in Germany?

Adults typically wait 18 to 24 months, longer in some regions, and many waiting lists are closed. For children the wait is around 6 to 12 months, with social paediatric centres often the fastest point of contact.
