October is ADHD Awareness Month in the UK, and this year's theme – "The Many Faces of ADHD" – couldn't be more relevant for workplaces. Because here's the reality: ADHD doesn't look like what most people think it does.
When you picture an employee with ADHD, what comes to mind? Perhaps someone who can't sit still, constantly interrupts meetings, or leaves projects half-finished? These stereotypes are not just outdated – they're actively harmful, creating stigma that prevents people from seeking support and stops organisations from recognising the genuine challenges their teams face.
With an estimated 3-4% of adults in the UK having ADHD (that's potentially 1.5 million people), the chances are you're already working alongside colleagues with ADHD, whether you realise it or not. And many of them are masking their symptoms, exhausted from trying to fit into neurotypical expectations, and worried about the consequences of being open about their diagnosis.
The Myths That Keep People Silent
Myth 1: "ADHD Is Just About Being Hyperactive"
This is perhaps the most persistent and damaging myth. Yes, hyperactivity is one presentation of ADHD, but it's far from the whole picture. Many adults with ADHD – particularly women – present with the predominantly inattentive type, which looks nothing like the bouncing-off-walls stereotype.
Inattentive ADHD might show up as someone who appears daydreamy, struggles to follow lengthy conversations, frequently loses track of paperwork, or finds their mind wandering during meetings despite genuinely wanting to engage. These employees aren't being rude or lazy – their brains process information differently.
The reality is that ADHD has three main presentations: predominantly hyperactive-impulsive, predominantly inattentive, and combined type. Each looks different, and none of them match the cartoon version of ADHD that dominates public perception.
Myth 2: "ADHD Is a Childhood Condition – Adults Grow Out of It"
Tell that to the adults who've spent decades developing coping strategies, feeling like they're constantly swimming upstream, or only receiving their diagnosis in their 30s, 40s, or even later. ADHD doesn't magically disappear when someone turns 18.
What actually happens is that adults with ADHD become incredibly skilled at masking their symptoms and developing workarounds. They might set multiple alarms, create elaborate systems to remember tasks, or work late into the evening to make up for time lost to distractions during the day. This constant adaptation is exhausting and often goes unnoticed by colleagues and managers.
The diagnostic criteria for ADHD were initially developed based on how the condition presents in young boys. As we've learned more about how ADHD manifests across different ages, genders, and life stages, it's become clear that many adults have been struggling with undiagnosed ADHD for years.
Myth 3: "If You Can Focus on Things You Enjoy, You Don't Have ADHD"
This misunderstanding causes enormous harm. People with ADHD often experience "hyperfocus" – intense concentration on activities that interest them, sometimes to the exclusion of everything else. Seeing someone completely absorbed in a project one day and struggling to start a mundane task the next doesn't mean they're being selective about when their ADHD "works" – it's how ADHD actually operates.
The ADHD brain seeks stimulation. When a task provides enough interest, novelty, or urgency, the brain can engage fully. When it doesn't, getting started feels like pushing a boulder uphill. This isn't a choice or a character flaw – it's neurobiology.
Myth 4: "ADHD Means You're Not Intelligent"
ADHD has nothing to do with intelligence. People with ADHD span the full range of cognitive abilities, and many are highly intelligent, creative, and successful. What ADHD affects is executive function – the brain's management system that handles planning, organisation, time management, and emotional regulation.
You might have a brilliant strategic thinker on your team who struggles to submit their expenses on time, or a creative problem-solver who finds structured meetings draining. Their ADHD doesn't limit their intelligence; it just means their brain works differently when it comes to specific tasks.
Myth 5: "People With ADHD Just Need to Try Harder"
This myth is particularly cruel because people with ADHD are often already trying harder than anyone realises. They're trying to remember that critical email. They're trying to stay organised. They're trying to manage their time effectively. The problem isn't effort – it's that their brain's wiring makes these tasks genuinely more difficult.
Telling someone with ADHD to "just focus" or "try harder" is like telling someone with poor eyesight to just try to see better. It shows a fundamental misunderstanding of what ADHD actually is: a neurodevelopmental difference that affects how the brain regulates attention, processes information, and manages executive functions.
Myth 6: "ADHD Is Over-Diagnosed and Over-Medicated"
The statistics tell a different story. Research suggests that ADHD is actually underdiagnosed in the UK, particularly in women. Many people who could benefit from assessment and support never receive it because of stigma, long NHS waiting lists (often 2-3 years), or difficulty accessing private assessment.
As for medication, treatment for ADHD is highly individualised. Some people find medication transformative; others prefer therapy, coaching, or workplace adjustments. There's no one-size-fits-all approach, and nobody is forcing anyone to take medication they don't want.
The Real Costs of ADHD Stigma
When ADHD remains misunderstood and stigmatised in your workplace, the consequences ripple outward. Employees who might benefit from support don't seek it. People burn out trying to meet neurotypical expectations without the adjustments that would help them thrive. Talented team members leave for more understanding environments.
And here's what really matters from a business perspective: poor mental health costs UK employers billions annually. When people with ADHD don't receive appropriate support, they're more likely to experience anxiety, depression, and burnout – all of which impact absenteeism, presenteeism, and turnover.
Creating a Culture That Sees All Faces of ADHD
Breaking down stigma starts with education. When managers and teams understand what ADHD actually is (and isn't), they can move beyond stereotypes to see the people in front of them.
This means recognising that the quietly struggling colleague might need support just as much as the visibly restless one. It means understanding that ADHD can coexist with high performance, creativity, and valuable skills. It means creating space for people to be open about their neurodiversity without fear of judgment or career consequences.
ADHD Awareness Month gives us a chance to have these conversations, challenge our assumptions, and build workplaces where different types of brains can all contribute their strengths. Because when we move beyond myths and stereotypes, we create environments where everyone – not just neurotypical people – can do their best work.
