From the moment you walk in to the moment you receive your report, here's exactly what happens. No surprises, no discomfort, and no needles — just science. Suitable for children (6+), teenagers, and adults.
Choose your package — ADHD Brain Screening (£595), Comprehensive (£845), or Family Package (£1,095). Pay securely via Stripe and choose your preferred date. We'll confirm within 24 hours. See full pricing details.
When you arrive, we'll explain the entire process, answer any questions, and make sure you (or your child) feel relaxed. The environment is calm and clinical but not intimidating — no hospital vibes.
We place a lightweight textile EEG cap on your head and position four dry, gold-plated spring-loaded electrodes at specific locations on the 10-20 international system. Two small clips attach to your earlobes as reference points.
You sit still and focus on a cross displayed on screen. Your brain activity is recorded across all four channels in real time. This captures your baseline brain state — the pattern your brain produces when it's alert but not actively processing a task.
You close your eyes and relax. We record the same four channels. The brain produces different patterns with eyes closed versus open — the difference between these conditions reveals important information about cortical reactivity.
A computerised task appears on screen. Green circles = press the spacebar. Red squares = don't press. It runs for 3 minutes at varying speeds, measuring your ability to sustain attention and inhibit impulses.
Throughout the recording, our software performs Fast Fourier Transform (FFT) spectral analysis on all four channels, computing frequency band powers (delta, theta, alpha, beta, gamma) and the theta/beta ratio approximately five times per second.
Your results are automatically compiled into a comprehensive PDF report including your theta/beta ratio with z-score, all frequency band powers, Go/No-Go performance metrics, age-matched normative comparison, and clinical interpretation guidance. Emailed to you the same day. Use it as evidence for your GP, for a Right to Choose referral, EHCP application, or Access to Work claim.
Baseline cortical activity. Focus on fixation cross. Captures resting theta/beta ratio — the primary ADHD biomarker.
Relaxed with eyes closed. Measures alpha reactivity and compares TBR across conditions for a fuller picture.
Computerised attention and impulse control test. Green = press. Red = don't. Measures RT, omissions, commissions.
Your TBR at Cz and Fz, the FDA-referenced biomarker, with a z-score showing how many standard deviations you fall from the healthy age-matched average.
Complete power spectrum across delta, theta, alpha, beta, and gamma bands for both eyes-open and eyes-closed conditions.
Reaction time, RT variability, omission rate, commission rate, and total accuracy — all compared against age-specific norms.
Every metric compared against published norms from 311+ research subjects with full peer-reviewed citations. Includes percentile ranking.
Average beta power across F3 and F4 electrodes. Low frontal beta may indicate cortical hypoarousal — a pattern commonly associated with ADHD.
Plain-English explanation of what your results mean, the clinical significance of each metric, and guidance on next steps. References FDA and AAN guidelines. Designed to support psychiatric assessments and help navigate the NHS ADHD pathway.
On ADHD medication? Discuss with your prescribing clinician whether to take your medication before the screening. We can scan you medicated or unmedicated — both have clinical value. Our Medication Scan (£345) is specifically designed to compare brain activity on and off medication.
