Private ADHD Assessment in London
If you’ve spent years wondering why everyday things feel so much harder for you than for everyone else (staying focused, finishing what you start, remembering appointments, sitting still in meetings), an ADHD assessment can finally give you a clear answer. At BritMed Healthcare, you’ll be assessed by Prof. Ahmed El-Missiry, a consultant psychiatrist in London with more than 30 years’ experience. Because he’s a psychiatrist, he can diagnose ADHD and, where it’s right for you, prescribe and monitor medication.
Adult and adolescent assessments cost £370 and take 45 to 50 minutes. You can be seen in person in London or by video from anywhere in the UK, usually within a few days. No GP referral is needed if you’re paying yourself.

What is ADHD Assessmentand When Should You Consider It?
Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental condition, which means it affects how the brain develops and works from childhood onwards. It isn’t caused by laziness, poor parenting or too much screen time. ADHD mainly affects attention, activity and impulse control, and it often comes with real strengths too, such as creativity, energy and the ability to focus intensely on things that interest you.
ADHD starts in childhood, but many people aren’t diagnosed until adulthood. That’s especially true for women and girls, people who did well at school, and anyone who found ways to cope that eventually stopped working.

ADHD Assessment Frequently Asked Questions
Is ADHD treated by a psychiatrist?
Yes. In the UK, psychiatrists are the primary specialists for diagnosing ADHD and initiating medication. They assess your symptoms against clinical criteria and monitor the biological effects of treatment. While GPs provide ongoing care, the initial specialist oversight ensures the most accurate management plan.
What is the 24-hour rule for ADHD?
This is a self-regulation strategy used to manage impulsivity. It involves waiting 24 hours before acting on an impulse, such as making a non-essential purchase or responding to a sensitive email. This “cooling-off” period allows the brain to process the urge logically rather than emotionally.
How to calm ADHD before bed?
Establish a “low-dopamine” wind-down routine. Dim the lights and avoid screens an hour before sleep to encourage melatonin production. Many find sensory tools, like weighted blankets or white noise, helpful. Consistent sleep hygiene is vital for regulating the often-disrupted circadian rhythms associated with ADHD.
How can I reset my ADHD lifestyle?
Focus on “externalising” your executive functions. Use digital timers, visual planners, and body-doubling (working alongside someone else). Instead of radical changes, implement small, dopamine-friendly habits. Prioritising sleep, nutrition, and professional coaching can help build a sustainable environment that works with your brain, not against it.
What is the hardest age for ADHD?
Specialists often identify early adolescence (ages 12–15) or the transition to early adulthood as the most challenging. These periods involve a significant increase in academic demands and social complexity, often outpacing the development of executive functioning skills such as planning, emotional regulation, and self-organisation.
What do the Japanese use to treat ADHD?
Treatment in Japan typically involves a combination of pharmaceutical intervention and psychosocial support. Common medications include methylphenidate (Concerta) and atomoxetine (Strattera). Japan is known for rigorous diagnostic standards and a strong emphasis on environmental adjustments within the school system to support neurodivergent students.
What country has the highest rates of ADHD?
While global prevalence is approximately 5%, reported rates are highest in countries like the United States and Israel. This is largely attributed to advanced screening protocols, greater public awareness, and differences in diagnostic criteria compared to other nations, where ADHD may still be under-diagnosed.
What are the new treatments for ADHD?
Recent developments include “digital therapeutics”—specifically designed video games that improve attention—and new non-stimulant medications like Viloxazine. Research is also expanding into neuromodulation, such as Trigeminal Nerve Stimulation (TNS), which offers a non-invasive, non-pharmacological option for managing symptoms during sleep.
What is the 30% rule in ADHD?
Proposed by Dr Russell Barkley, this rule suggests that individuals with ADHD often have an “executive age” roughly 30% behind their chronological age. For instance, a 10-year-old may have the self-regulation skills of a 7-year-old. This perspective helps in setting realistic expectations for development and independence.
