Neurodiversity in the workplace goes beyond the conditions most people recognize –  ADHD, autism, and dyslexia. While they may be the most talked about, they are certainly not a complete list.

Neurodiversity researchers recognize at least four additional conditions under the neurodiversity umbrella: dyspraxia, dyscalculia, dysgraphia, and Tourette syndrome. Each one affects how people express ideas, process information, and show up in professional environments. Most people have never heard of three of those, yet they are surprisingly common. Unsurprisingly, the people with the conditions are usually misunderstood.

These conditions almost never travel alone. Co-occurrence is the norm, not the exception. The person on your team with dyslexia may also have dysgraphia. Your most creative thinker might be navigating dyscalculia alongside ADHD. The good news is that the same mindset of focusing on what people have to contribute and being flexible in how information is shared will help, no matter how a person’s brain is wired.

Dyspraxia: When the Signal Gets Scrambled

Dyspraxia  can also be called Developmental Coordination Disorder, or DCD. It affects an estimated 6–10% of the population to some degree, with about 2% severely affected. It’s a neurological condition that disrupts the planning and execution of movement. That includes fine motor skills, spatial orientation, and the organization of physical actions in sequence.

Coordination shapes communication more than you might expect.  When under pressure, dyspraxia can affect verbal fluency, the ability to organize thoughts quickly in conversations, and the processing demands of fast-paced exchanges. The person who seems hesitant in meetings, takes longer to gather their thoughts before responding, or appears flustered when put on the spot,  may be navigating something their colleagues can’t see.

The flip side is worth knowing. People with dyspraxia often bring strong verbal communication skills when given time to prepare. They tend to be creative, strategic thinkers who approach problems from unconventional angles. They frequently develop exceptional empathy — partly because navigating a world that wasn’t designed for them requires constant perspective-taking.

If you have dyspraxia: Preparation is key. Ask for agendas before meetings, use voice notes instead of written lists, and advocate for processing time.

If someone on your team has dyspraxia: Give them written briefs before discussions. Avoid putting them on the spot in group settings. Measure their thinking, not their speed.

Dyscalculia: It’s Not Just “Bad at Math”

Dyscalculia is a specific difficulty processing numbers, numerical relationships, and mathematical concepts. Estimates put it at 3–6% of the population, with some studies suggesting as high as 10%. Like dyslexia, it has nothing to do with general intelligence. The brain simply doesn’t map numerical information the way most people do.

Especially at work, data is everywhere. Budgets, timelines, project estimates and quarterly reports are just a few examples. When workplace communication is increasingly “data-driven,” dyscalculia creates a gap between what someone understands conceptually and how they can express or absorb it numerically.

It is not about a lack of intelligence or a non-analytical mind. It’s about the mechanics of the analysis.

On the plus side, dyscalculia is consistently associated with strong oral communication, high creativity, and reasoning ability that doesn’t depend on numerical processing. The person who struggles through your budget slide may be the sharpest conceptual thinker in the room.

If you have dyscalculia: Use visual representations of numerical data, calculators, and allow extra processing time on data-heavy materials.

If someone on your team has dyscalculia: Don’t conflate math fluency with analytical capability. Show charts and visuals alongside raw numbers. Be open minded to letting them demonstrate their thinking in ways that don’t require numerical fluency.

Dysgraphia: When Writing Doesn’t Match Thinking

Dysgraphia is a neurological condition affecting written expression. Not just handwriting, but the entire process of translating thought into written form. Spelling, letter formation, word spacing, and written organization can all be affected. It frequently co-occurs with dyslexia and ADHD, so it often goes undetected as a separate condition.

It’s important to note that dysgraphia doesn’t affect verbal intelligence. The bottleneck is specific to writing. The person whose emails look disorganized or whose written reports only make sense once they verbally explain them, may be one of your highest-functioning thinkers. You just can’t see it in their written output.

In a workplace that runs on written communication, this mismatch can easily derail a career. Performance reviews often prioritize written deliverables. Promotions favor people who communicate “professionally” in writing. The standard is set without ever considering that the standard itself might be screening out capable people.

If you have dysgraphia: Speech-to-text tools, voice memos, and talking through ideas before writing them down can significantly reduce the friction. When sending important written information, request a meeting to explain it in person first.

If someone on your team has dysgraphia: Evaluate their thinking separately from their writing mechanics. Give them alternatives to written-only deliverables. Don’t mistake spelling errors or structural looseness for laziness or lack of knowledge.

Tourette Syndrome: More Than the Stereotype

Tourette syndrome (TS)  affects roughly 0.6% of the population — smaller than the other conditions in this post, but worth understanding because the stereotype is so misleading. TS is characterized by involuntary repetitive movements and vocalizations called tics. These can be motor (blinking, head movements) or vocal (throat clearing, sounds, words).

Involuntary swearing, called coprolalia, affects only about 1 in 10 people with Tourette’s. What most people with TS actually experience is far more subtle. The tics can be easy to overlook or may be actively suppressed. Suppressing those tics takes considerable cognitive effort and leaves less bandwidth for everything else, including communication.

About 85% of people with Tourette’s also experience ADHD or OCD as co-occurring conditions. The combination shapes how they communicate, process, and show up at work in ways that go beyond the tics themselves.

Common strengths are enhanced cognitive control, strong information processing, high resilience, and the ability to hyperfocus. People with TS often develop extraordinary coping capacity precisely because they’ve had to.

If you have Tourette’s: The biggest drain is usually social management. The need to monitor others’ reactions to tics can be draining, making everyday conversations exhausting.  Environments with genuine psychological safety will help you focus your energy on the work that matters.

If someone on your team has Tourette’s: Tics are involuntary. Reacting to them, even subtly, adds social pressure that compounds over time. Instead of trying to ignore it, address it and normalize without making it a big deal.

The Bottom Line

ADHD, autism, and dyslexia get most of the attention. But dyspraxia, dyscalculia, dysgraphia, and Tourette syndrome are present in your workplace right now — mostly undiagnosed or communicated, and causing a lot of hidden stress.

These conditions may show up as the employee who hesitates in meetings, struggles with written reports, freezes on a data slide, or manages invisible demands the rest of the room doesn’t notice. They look like performance problems, but they are really translation problems.

Every difference you can understand adds a new legend to your map. This makes you a better communicator, a better manager, and a more effective leader. It makes you more NeuroConversant.

Knowing that there are so many different legends to the map is a great start. Putting that knowledge to work requires new skills. I work with leaders to help them get the most out of their teams. If you are ready to make the diversity on your team a strategic advantage, let’s talk.
