More employers are finally talking about neurodiversity. But one common, well-meant mistake keeps muddying the conversation: treating neurodivergence as a mental health issue.
You see it in corporate messaging, training modules and policies that file neurodiversity under the mental health umbrella. Both matter for wellbeing at work. They are not the same thing, and treating them as one can do more harm than good.
If you work in HR, learning and development or people management, this post explains the difference, why it matters, and how to support neurodivergent employees properly.
What is neurodiversity?
Neurodiversity describes the natural variation in how all human brains process information, communicate and interact with the world. People whose brains work differently from what society treats as typical are described as neurodivergent. That includes autistic people and people with ADHD, dyslexia, dyspraxia, dyscalculia or Tourette syndrome.
Neurodivergence can shape communication, sensory processing, attention, memory, learning and executive function. These are lifelong developmental differences, not mental health conditions. Our guide to neurodiversity in the workplace covers the basics, and how neurodiversity shows up at work describes the traits managers are likely to notice.
What is mental health?
Mental health is a person’s emotional, psychological and social wellbeing. It affects how we handle stress, relate to others and make decisions. Mental health conditions include anxiety, depression, bipolar disorder, PTSD and eating disorders. They can be short or long term, and they can come and go.
Neurodivergent people can also have mental health conditions, and rates are higher among people who have spent years being misunderstood or excluded. But the two are not interchangeable.
Why the distinction matters for employers
People get the wrong support
Employee assistance programmes, counselling and stress management can help. They won’t remove the barriers that come from inaccessible processes, sensory environments or unclear communication.
A dyslexic employee who needs text-to-speech software doesn’t need a meditation app. An autistic employee who finds an open-plan office overwhelming doesn’t need resilience training. They need a change to the environment.
It frames neurodivergence as something to fix
Treating neurodivergent identities as illnesses sends the message that being neurodivergent is a flaw. Managers may then assume someone is unwell when they simply work or communicate differently, and miss the strengths they bring.
It creates legal risk
In the UK, many autistic people and people with ADHD or dyslexia meet the definition of disability under the Equality Act 2010, which gives employers a duty to make reasonable adjustments. Our post on ADHD, autism and the legal definition of disability looks at a recent appeal case. Relying on general wellbeing programmes instead of adjustments can leave you short of your legal obligations. Acas has helpful guidance on neurodiversity at work.
An example
Take a hypothetical employee, Sophie. She has ADHD and is good at her job, but back-to-back meetings and vague written instructions make it hard for her to plan and prioritise. Her manager notices she seems stressed and refers her to the employee assistance programme.
The programme offers counselling and mindfulness tips. Sophie goes once and finds it doesn’t help. What she needed was fewer meetings, a quick conversation to confirm priorities, and a shared task management system.
Because her needs were treated as stress, the wrong tools were used. She ends up feeling misunderstood, and her performance dips for reasons that were easy to fix.
What HR should do instead
Run separate but connected strategies
Neurodivergence and mental health overlap, but they need different tools. A neurodiversity strategy focuses on reasonable adjustments, inclusive communication, manager training and fair recruitment. A mental health strategy focuses on access to therapy, crisis support, psychological safety and emotional wellbeing. You need both.
Train managers on the difference
Most misunderstandings happen at line manager level. Help managers understand that neurodivergent employees may need different communication styles, may find their capacity for planning and organising varies from day to day, and often work best with predictability and structure. None of that is a sign of being unwell, and expectations can stay high. The way of working is what changes.
Offer adjustments proactively
Don’t wait for people to ask. Build inclusive habits into teams from the start: share information in more than one format, record meetings or send summaries, let people plan their own day where possible, and ask “How can I support you to do your best work?” rather than “Are you okay?” A working styles guide makes that conversation easier.
Be precise in policies and messaging
Review HR documents, intranet pages and internal campaigns. If neurodiversity sits inside mental health with no clear definitions, separate them. You might say: “We support both mental health and neurodiversity at work, and we know they are different. Our wellbeing programme offers mental health support, and our inclusion strategy focuses on creating a workplace that works for every kind of mind.”
Final thoughts
Grouping neurodiversity with mental health can look harmless, even progressive. For neurodivergent employees it can feel like being mislabelled. HR teams that are confident about the difference can move from generic wellbeing messages to support that actually fits.
How Enna can help
When an employee needs support, a workplace needs assessment identifies the specific adjustments that will help, so nobody is defaulting to counselling for a problem the environment created. Workplace coaching then helps neurodivergent employees and their managers put new strategies into practice.
To build the distinction into everyday management, our Neurodiversity Foundations for Managers course is a good starting point, and a neuroinclusion audit will show where your policies blur the two. Book a call to discuss your strategy.
