Adult ADHD – five key take-home messages for GPs
Continuing our series highlighting key sessions from Pulse Virtual and Pulse Live events, Dr Tabish Shah provides a summary of his five key take-home messages for GPs on the recognition and management of attention deficit hyperactivity disorder (ADHD) in adults
1. ADHD is a lifelong neurodevelopmental condition – not a passing trend or myth
Attention deficit hyperactivity disorder (ADHD) is a lifelong neurodevelopmental condition that begins in childhood and persists into adulthood. In line with NICE guidelines on ADHD and the Diagnostic and Statistical Manual of Mental Disorders 5th edition (DSM‑5), symptoms must be present before age 12, occur in at least two settings and cause functional impairment. Adult diagnosis reflects delayed recognition and not late onset.
ADHD affects approximately 3–5% of the population in England, with approximately 5% of children and 3–4% of adults affected, and around 2.6% of adults worldwide. Yet only a small proportion receives medication, despite evidence that most would benefit.
Some common misconceptions are outlined in the box below.
Common ADHD misconceptions
- ‘We all have a bit of ADHD’
- It’s a social media trend
- High achievers cannot have ADHD
- Only hyperactive boys are affected
In many adults, ADHD remains undiagnosed and untreated, especially among women who tend to mask symptoms more (there is a 3:1 male to female diagnosis ratio).
It is important to breakdown stigmas and understand ADHD through a neurodiversity framework, where different brains bring different strengths. Traits such as hyperfocus, creativity, energy and rapid idea generation can be assets harnessed in the right environment.
The goal of diagnosis is not to change personality, but to reduce impairment and improve quality of life.
2. Untreated ADHD carries significant personal and societal costs
ADHD affects education, employment, relationships and physical health. In the UK, untreated ADHD is estimated to cost billions annually through school dropout, unemployment mental health difficulties, substance misuse and criminal justice involvement.
Crucially, ADHD must be considered ‘below the neck’ as well – as failure to acknowledge and treat associated physical ailments may reduce life expectancy up to an astonishing 13 years.
Associated comorbidities
- Obesity and cardiovascular disease
- Substance misuse (alcohol, nicotine, drugs)
- Sleep disturbance
- Eating disorders
- Connective Tissue Disease (Ehlers-Danlos Syndrome)
Many of these comorbidities stem from impulsivity, emotional dysregulation, poor planning and dopamine-seeking behaviours. However, most of these risks are modifiable: early recognition, medication, psychoeducation and lifestyle change can significantly improve long-term outcomes.
The ADHD-Ehlers-Danlos Syndrome link remains an emerging area of research, with likely multifactorial overlapping biological and neurological mechanisms involved. One hypothesis is that autonomic nervous system dysregulation, commonly seen in people with Ehlers-Danlos Syndrome, also affects attention and arousal; another is that shared genetic pathways underlying each condition influence both collagen structure and neurodevelopment.
3. Assessment and referral is achievable within a 10-15 minute GP consultation
The GP’s role is to identify probable ADHD, assess risk and refer appropriately. Screening tools such as the Adult ADHD Self-Report Scale (ASRS) v1.1 help identify those who may need referral. This is completed and returned ideally with the assistance and support of a close informant. An additional free written section is also beneficial, documenting symptoms before age 12.
Even if screening is borderline, strong clinical suspicion justifies referral. For example, they may present with score of 3/6 (where positive ≥4) on Part A, but with a high symptom load on Part B and clear functional impairments across the life span consistent with ADHD.
ADHD often does not present in isolation and may co-occur with other mental and physical health conditions. Furthermore, its symptoms may overlap with disorders such as anxiety, depression, bipolar disorder, thyroid dysfunction and menopause. These conditions should therefore be considered during differential diagnosis to ensure accurate assessment and management. Co-existing autism (often termed AuADHD) is often prevalent, with overlapping executive and sensory traits. These would necessitate further follow up and management accordingly.
4. ADHD is highly treatable and medication can be transformative
Medication is highly effective for many adults diagnosed following a comprehensive assessment via a semi-structured diagnostic interview (based on DSM-5 criteria). NICE guidance recommends stimulants such as lisdexamfetamine and methylphenidate as first-line treatments. Non-stimulant options include atomoxetine and guanfacine where stimulants are not tolerated or suitable.
Effective prescribing requires:
- Structured titration (typically 12–15 weeks).
- Monitoring of blood pressure, pulse and weight.
- Ongoing specialist oversight via shared care.
When optimised, many patients describe medication as life-changing, citing improved mental clarity with less noise distraction and a daily functional improved balance. However, medication works best alongside practical strategies that involve adequate hydration, higher protein meals, sleep hygiene, structured routines and minimising caffeine and alcohol.
5. ADHD requires a holistic approach to achieve overall improved outcomes
Medication is powerful, but long-term success requires ‘skills as well as pills’. Psychological interventions, including ADHD-specific CBT, coaching and psychoeducation, can build strategies through acceptance, time management, emotional regulation and self-awareness. Coaching can help translate insight into structured goal-setting and accountability. Few NHS services exist for these interventions: most are through private avenues or assessment and diagnosis packages. However, local talking therapy services may cover some general aspects.
Support networks and reputable patient resources signposted by GPs can empower individuals to advocate for reasonable adjustments and understand their condition more fully, with sleep support through hygiene discussion, CBT or medication if appropriate.
Supportive environmental adjustments
- Quiet workspaces
- Noise cancelling headphones
- Movement breaks
- Flexible or hybrid working
- Exam accommodations
Importantly, ADHD does not define a person. It is one aspect of identity. With validation, structured support, and effective treatment, individuals with ADHD can thrive academically, professionally and socially.
Summary points
- ADHD is common, lifelong and hugely impactful.
- Early recognition, structured assessment, appropriate medication and holistic support can dramatically alter life trajectories.
- The core message is one of hope, as when it is properly understood and managed, ADHD is not a limitation, it is a difference that with the right support can coexist with resilience, creativity and success.

This seems a rather one sided article. There are no definitive test for ADHD. Stimulant medication arguably improves attention in everyone so what does meaningful improvement actually look like? When should medication stop? What constitutes failure. What is the aim of treatment ie is it just to get people to function better in a world not designed for them? There are so many questions which aren’t addressed here
Please can we have a full conflict of interest declaration here ? Does the author own, benefit or work for a private or NHS/RtC provider ?
I thought this was a great one-pager with references for further reading. BUT having spent many hours trying to complete online referrals on various portals of RTC providers, I cannot agree that referral is possible within an appointment
No mention of diagnosis creep or over- medicalization here – see ” the age of diagnosis” by Dr Suzanne o’ sullivan

“Dopamine-seeking behaviours” would not include reading this article
@joy Rider I believe that the myth has been proven untrue. You only experience improved attention with stimulant medication if you have ADHD. Not if you don’t
I know this doctor personally and there is absolutely no involvement with any right to choose providers, I’m surprised to even imply that? It’s a colleague trophy to educate colleagues, I hope if you publish any articles colleagues will jump to conclusions immediately or make false assumptions. We must build eachother up, not destroy others trying to help.
This is a great article and definitely needed with so much missing information and education out there. Obviously not everything can be converted in such a small space. Something I’ve found helpful with right to choose referrals is using websites like thinkadhd created by colleagues so patients can put their difficulties or asking the patients themselves to fill the referral details as you are right, too much to do in too little time. I’ve never heard a patient who is not glad too do it themselves or if their executive dysfunction is too great and they can’t do it, usually I ask for a relative or choose friend to help them complete and this works a treat. DOI, I do not work for any right to choose provider to I’m a general practice gp and author of the book Neurodivergence in primary care to help educate colleagues with many of the questions and comments posted here and help fight misinformation.
Sorry autocorrect was failing, I hope you never get the hate that’s being dished out.
So I have ADHD (diagnoised back in 2009 when it rejected a full day of psychological testing as well as the questionaires).
The different referral forms for the RTC providers where it is not prefilled can take longer than the actual patient appointment time. It has helped with the single access referral point in our area as now a single form.
Does he really expect you to do a secondary assessment in any consult where a patient doesn’t meet the 1st screening cut off. I can’t remember the last time I saw someone who didn’t meet the cut off.
There seems to be an over-reliance on medication with many people thinking medication is a panacea. ADHD forums are full of patients complaining about a lack of satisfaction with the effect of medications.
I have seen people angry or upset if they are not given an ADHD diagnosis because they are convinced it must be that. It might be beneficial for any teaching or article on ADHD to discuss other things that can cause executive dysfunction (main symptoms I find adults with & without an ADHD diagnosis complain of)
Im sure everyone is aware of the exponential increase in adult patients (even teenagers) thinking they have ADHD thanks to social media and influencers.
In london we’ve had an impossible amount of interest for patients to be “tested”. Frequently they initially report symptoms of anxiety or depression or when told their symptoms don’t sound like ADHD, but a mild alternative mental health condition, they reoreswnt at a later date to see the same gp or another with a completepy different history and tick the boxes in the ADHD questionnaire. Even though we suspect they are fabricating their symptoms, patients demand a referral to the ADHD clinic. Our local weighting tine for NHS ADHD clinic is 50 months (was 3 months, 5 years ago).
Ofcourse theyve heard about the Right to Choose clinics and demand a referral there. Once referred they return with a diagnosis of ADHD, very rarely these clinics diagnose the patient as NOT having ADHD.
If you watched BBC panorama a couple of years ago you’d see how much money they make so its in their interest to overdiagnose the condition.
This has led to go surgeries who previously may have 10 pts on ADHD suddenly jumping up to 50… going way above the national prevelance.
The social media generation is
There needs to be more discussion about this, and the implications of people without ADHD being on drugs that have significant systemic effects and their long term effects.
The governent and media need to be involved in addressing this issue.
This is a strong, evidence-based article that highlights how far parts of the profession still need to catch up on adult ADHD.
The suggestion seen repeatedly in these comments is that ADHD is being “overdiagnosed” or is somehow a trend is not supported by the evidence. Adult prevalence has been consistently estimated at around 2–3%, and the majority remain undiagnosed.
What has changed is not the condition, it’s recognition.
Dismissing patients as “TikTok diagnoses” or implying ADHD is a lifestyle label ignores decades of research and the very real impairment associated with untreated ADHD, which include poorer mental health, occupational difficulties, and increased risk across multiple domains. Patients deserve better than dismissive attitudes.
Yes, general practice is under pressure. Yes, shared care arrangements are inconsistent. But those are system failures, not reasons to question the validity of the condition itself.
This article does exactly what is needed, it’s just a summary that presents ADHD as a legitimate clinical issue requiring informed, pragmatic primary care involvement. It is not intended to answer every clinical nuance of the condition!
If anything, the tone of some of these comments only reinforces why education like this remains necessary.
In a field where misinformation and frustration can easily dominate, this article provides a refreshingly clear, professional, and compassionate voice.
Absolutely agree with Paul – referral to a provider who will see the patient within 2 years is not possible with a 10-15 minute appointment, unless you mean one appointment every day for years?
And getting reviews of incoming patients on medication? They are just abandoned with no responsibility taken for follow-up as required by the shared-care systems and prescribing requirements, they are just dumped, often by foreign doctors who even refuse to give a safe handover with diagnosis and records direct to a GP. I am afraid this does make one suspicious that some of these are only given the diagnosis and medication because the other doctor makes a profit from doing so.
