Fast, private ADHD brain screening for clients from Bishops Stortford and Hertfordshire. No GP referral required. Objective neurological data delivered in a same-day professional PDF report. Evidence your GP will take seriously, your school can use for an EHCP, or your employer can use for workplace adjustments.
If you're searching for ADHD screening near Bishops Stortford, you've probably been through the frustrating cycle: online quizzes that say "likely ADHD," a GP appointment that went nowhere, and an NHS waiting list stretching years into the future. In Hertfordshire, the average CAMHS wait is 2–3 years for children and 3–5 years for adults. Some areas report waits exceeding 5 years.
The private route isn't much better in terms of evidence. A private psychiatric assessment costs £700–£1,500 and is based entirely on conversation: questionnaires, rating scales, and a clinical interview. There is no brain measurement. No objective data. If you're near Bishops Stortford and you want something more concrete, something your GP can't dismiss as "everyone struggles with that," you need actual brain data.
That's what we provide. In 30 minutes, we measure the electrical activity of your brain, compare it against published norms from 311+ research subjects, and give you a same-day professional report. Not an opinion. Not a score on a checklist. A direct measurement of what your brain is doing. Our results explained guide helps you understand every data point.
Five frequency bands tell the story of your brain's electrical activity. Delta (1–4 Hz) relates to deep processing and is elevated in drowsy states. Theta (4–8 Hz) is the ADHD-relevant band — elevated theta indicates an under-aroused cortex that struggles to maintain focused attention. Alpha (8–12 Hz) reflects relaxed awareness and is often elevated in anxiety. Beta (12–30 Hz) indicates active concentration and engagement. Gamma (30–45 Hz) relates to higher cognitive processing.
We measure all five bands at four cortical sites simultaneously: Cz (vertex — the FDA-standard TBR measurement point), Fz (frontal midline — secondary TBR site), F3 (left prefrontal — executive function), and F4 (right prefrontal — attention regulation). This four-channel configuration captures the cortical regions most relevant to ADHD neuroscience.
Your report shows the absolute and relative power in each band at each site, the TBR at Cz and Fz, and z-scores comparing each measurement against published age-matched norms. The full picture, not just a single number.

Everything starts with a 5-minute setup: cap on, electrode check, clear explanation. The brain recording takes 7 minutes. We measure at four cortical sites: Cz (primary TBR site), Fz (secondary TBR site), F3 (left prefrontal — executive function), and F4 (right prefrontal — attention regulation). Data is processed using Fast Fourier Transform into five frequency bands: delta, theta, alpha, beta, and gamma.
The key measurement is the theta/beta ratio at Cz — an elevated TBR indicates cortical hypoarousal, the pattern most consistently associated with ADHD. Your result is expressed as a z-score against age-matched norms.

Nervous about the appointment? Most people are — especially if they've had difficult medical experiences before, or if they're anxious about what the results might show. Here's what to expect: a calm, friendly environment where every step is explained before it happens. No surprises. No pressure. No judgment.
The screening takes 30 minutes total. The brain recording itself is just 7 minutes: 2 minutes eyes open, 2 minutes eyes closed, 3 minutes doing a simple press-the-button task. The cap is lightweight, dry (no gel), and most people forget it's there within a minute. You'll see your own brain waves on screen in real time — most people find this fascinating rather than stressful.
After recording, your data is processed and your report generated the same day. If you've booked the comprehensive package, we spend 20 minutes walking through every finding with you. Either way, our ADHD support hub is available afterwards with guides on understanding your results, next steps, coping strategies and more.
There's very little preparation needed — that's part of the appeal. The main things to remember: clean hair (no heavy products or gel), normal sleep, normal food, and moderate caffeine. Arrive 5 minutes early so we can start on time, but there's no paperwork or questionnaires to complete beforehand.
If you're bringing a child, explain the process in simple, positive terms: 'we're going to listen to your brain waves with a special hat — it doesn't hurt at all and you'll be able to see your brain working on a screen.' Most children are curious rather than anxious when it's framed this way. Our parent's guide has more advice on preparing children.
If you're an adult who takes ADHD medication, let us know when booking. For a baseline screening, we typically recommend taking the test unmedicated (skip your morning dose). For a medication comparison scan, we need one session off medication and one on medication. We'll advise on the best approach for your situation.

We screen children aged 6 and above, teenagers, and adults of all ages from Bishops Stortford and across Hertfordshire. Each person is compared against age-matched normative data from published research — because a 7-year-old's brain is neurologically very different from a 40-year-old's.
For children, the most common scenario is parents who've been told their child "just needs to try harder." For teenagers, it's GCSE or A-level pressure exposing hidden attention difficulties. For adults, it's often a lifetime of wondering — sometimes triggered by a child's diagnosis.
Women and girls are particularly underserved by standard assessment. The inattentive presentation — quiet, dreamy, internally restless — is systematically missed by questionnaires designed around hyperactive boys. Our brain screening measures neurology directly, bypassing the behavioural bias.

Oppositional defiant behaviour in children is sometimes ADHD being misread. A child who refuses to start homework, argues about every instruction, and melts down over minor frustrations is often labelled as defiant or badly parented. But for many children, the oppositional behaviour is driven by ADHD — they can't start the homework because they genuinely cannot organise their thoughts, and the frustration of being unable to do what everyone expects manifests as anger.
Parents near Bishops Stortford hear 'they just need firmer boundaries' when what their child actually needs is ADHD assessment and support. Our brain screening provides the objective evidence that shifts the conversation from behaviour management to neurological understanding.
An elevated theta/beta ratio in a 'defiant' child is powerful evidence that the behaviour has a neurological basis — not a parenting one. It changes how schools, GPs, and family members respond. Our parent's guide includes advice on engaging your child's school SENCO with this evidence.
Every screening produces a detailed same-day report with theta/beta ratios, z-scores, frequency band analysis, and Go/No-Go attention task results — all compared against published age-matched norms.
This is the standard report included with our ADHD Brain Screening (£595). The Comprehensive Assessment (£845) adds a clinical interpretation letter addressed to your GP, school, or employer.
Objective brain data with z-scores gives your GP the evidence to write a stronger referral or submit a Right to Choose application.
SENCOs use our reports for EHCP applications, SEN register placements, and JCQ exam access (extra time, rest breaks).
Adults use the clinical letter for Access to Work applications — government-funded coaching, headphones, assistive technology.
Brain data gives a private psychiatrist an objective data point they wouldn't otherwise have, making assessment more focused.
Already on medication? A follow-up medication comparison scan (£345) shows objective before-and-after changes.
Still on the NHS waiting list? Our report gives you actionable evidence for school, work, and GP support right now.
During your screening, you'll see your own brain waves updating in real time on screen. Here's what the testing dashboard looks like during each phase of the 7-minute recording.

The screening report is designed to be actionable from day one. It's not a document that sits in a drawer — it's a key that opens specific doors. GP door: the clinical letter is formatted for medical professionals, with z-scores, methodology, and peer-reviewed citations. School door: the same letter addresses SENCO and EHCP requirements directly. Employer door: the letter provides the objective evidence required for Access to Work and reasonable adjustment requests.
We also provide guidance on what to say in each context. Our comprehensive package (£845) includes a 20-minute consultation where we walk you through the results AND advise on next steps specific to your situation — which pathway makes most sense, what to say to your GP, what to request from the school.
We always recommend staying on the NHS waiting list while pursuing our screening. The NHS pathway leads to fully-funded ongoing care. Our screening gives you evidence and support in the meantime — and data that strengthens your case when the NHS appointment finally arrives.

Our reports include peer-reviewed citations, z-scores against published normative data, and formal clinical interpretation letters. Many GPs across the UK have used our reports to support CAMHS referrals, Right to Choose applications to Psychiatry-UK, and urgent assessment requests. The report is designed to be credible and actionable within the NHS system. Our GP appointment guide includes scripts for presenting your results.
No GP referral is needed. You can book directly online or by phone. Many clients book the screening first, then take the objective results to their GP as evidence to support a formal referral. Having brain data in hand often makes the GP conversation significantly more productive — our GP appointment guide shows you exactly what to say.
Yes. The theta/beta ratio has been studied for over 30 years, replicated across hundreds of independent studies, and was referenced in the FDA's 2013 clearance of the NEBA System for ADHD evaluation. The International Society for Neurofeedback and Research (ISNR) rates qEEG assessment as Level 1 (Best Practice) for ADHD. It's well-established science, not experimental. Our ADHD brain guide explains the neuroscience in plain English.
No. Screening provides objective data; diagnosis requires comprehensive clinical assessment by a qualified professional. Our screening gives you neurological evidence to support the diagnostic process — it doesn't replace it. Think of it as providing the brain data that questionnaires and interviews cannot capture, making the eventual diagnosis more accurate and evidence-based. Our next steps guide explains every pathway from screening to formal diagnosis.
If you're currently waiting years on the NHS list with no support, paying £595–£845 for same-day objective data that can unlock GP referrals, school support, workplace accommodations, and Right to Choose applications is highly cost-effective. Many clients tell us the screening paid for itself within weeks through the support it unlocked.
