ADHD is still widely seen as something boys grow out of. In reality, many people reach their twenties, thirties or later before anyone suggests it, and some only recognise it in themselves after a child or friend is diagnosed. By then they’ve often spent years being called disorganised, lazy or “not living up to potential” without knowing why things felt harder than they looked for everyone else.
This post looks at why ADHD so often goes unrecognised in adults, what that can cost, and what to do if you think it might apply to you.
What ADHD looks like in adults
The NHS describes two broad groups of ADHD traits. Inattentive traits include being easily distracted, forgetting things, losing things and finding it hard to organise time or finish tasks. Hyperactive and impulsive traits include restlessness, talking a lot, interrupting and making quick decisions. Most people have some of both. You can read the full description on the NHS page on ADHD in adults.
In adults, visible hyperactivity often becomes an inner restlessness instead. That shift is part of why ADHD gets missed. Our post on signs you might have undiagnosed ADHD goes into more detail.
Why ADHD goes unrecognised in adults
Years of coping strategies
Many ADHD adults build systems to get by: rigid routines, endless lists, working late to catch up, or relying on last minute pressure to get started. These strategies can work well enough on the surface that nobody, including the person themselves, sees what’s underneath. Keeping it all going is tiring, though, and it often comes at a cost to rest and wellbeing.
Old ideas about who has ADHD
If you picture ADHD as a hyperactive young boy, an adult who daydreams through meetings won’t fit the image. Stigma doesn’t help either. The idea that ADHD is an excuse for laziness still puts people off asking for an assessment.
Inattentive ADHD and women
The NHS notes that ADHD is thought to be recognised less often in women, possibly because women more often have inattentive traits, which are harder to spot than hyperactive ones. Read more in our post on ADHD in women.
Other conditions get noticed first
ADHD often sits alongside anxiety, depression, dyslexia or autism. A person may be treated for anxiety for years before anyone asks whether ADHD is part of the picture.
Culture and access
Attitudes to neurodivergence differ between communities and families, and some people have good reasons to be wary of seeking a label. Access to assessment also varies by area and by whether someone can afford to go private.
What being unrecognised can cost
Going undiagnosed means missing the explanation, and often the adjustments that would help. At work, that can look like changing jobs often, being passed over for promotion, or a performance plan that targets the wrong thing. In relationships, forgetfulness or impulsive comments can be read as not caring. And years of feeling you’re falling short can wear down your confidence and mental health.
Many adults describe their diagnosis as a turning point because it finally makes sense of their past.
What to do if you think you have ADHD
Learn about it from good sources
Read reputable information, such as the NHS page linked above, and notice which descriptions match your experience. Our neurodiversity quizzes can help you reflect, though they aren’t a diagnosis.
Talk to your GP
Book an appointment if ADHD traits are affecting your work, studies or relationships. Bring specific examples, and anything from your childhood such as school reports. Your GP will ask about your experiences and may refer you to a specialist.
The specialist assessment
Assessments are usually with a psychiatrist or another ADHD specialist. They’ll ask about your childhood, education, work and relationships, and may talk to someone who knows you well. Waits can run to months or years. In England, the NHS says you may be able to use the Right to Choose scheme, through your GP, to find a clinic with a shorter wait.
Support while you wait and afterwards
You don’t need a diagnosis to ask for changes at work. Our list of reasonable adjustments for people with ADHD is a good starting point. After a diagnosis, support might include medication, coaching or therapy, depending on what you want and what’s offered.
How Enna can help
If a better fit at work is what you’re after, browse the Enna jobs board for roles with employers who take neuroinclusion seriously, or sign up for job alerts. Employers wanting to support staff who may be undiagnosed can find practical guidance on our ADHD in the workplace page, and we offer workplace coaching for ADHD employees and their managers.
