I am taking 10 people into a case study in brain health, stress resilience and longevity, on London's Harley Street. Six sessions of targeted brain stimulation, wrapped in the measurement I build everything on: biological age, cortisol rhythm, memory testing and your own wearable data. Below is the whole path, step by step, from the email you send me to the day I sit down and read your results with you.

This study is for people who are functioning, achieving, getting through the day. From the outside you look capable and in control. Inside, you are not as sharp, regulated or responsive as you would like to be. The focus dips. The patience runs thin. The sleep does not restore you. Your tests would probably come back normal. That gap between how you look and how you actually feel is exactly what I want to measure.
Read these slowly. If you feel seen by three or more of them, you are exactly who I designed this study for.
Exomind is a non-invasive brain stimulation device, designed to support cognitive and emotional health without medication or surgery. It uses ExoTMS, an advanced form of transcranial magnetic stimulation, to deliver targeted magnetic pulses to areas of the brain involved in mood regulation, executive function, emotional control and cognitive clarity.
Think of it like a training signal for the brain. Your brain works through electrical and chemical communication, and when certain pathways become underactive or poorly regulated, it can show up as poor focus, emotional reactivity, stress sensitivity, cravings, low motivation, brain fog or disrupted sleep. Exomind is designed to stimulate those circuits and support neuroplasticity, which is the brain's ability to form, strengthen and reorganise its connections.
Each stimulation session lasts 24 minutes. You will be sitting or lying on a chair or couch, relaxed. There is no pain, just a gentle buzzing sensation.
The device itself is FDA-cleared in the US for specific clinical protocols. That clearance is the manufacturer's, and it is not what this case study is testing. In this programme I am using it as part of a case study: I am measuring how your biology responds. I am not promising you an outcome, because that is not how I work. I test, I do not guess.
What a single session actually looks like, from walking in to walking back out.
In person on London's Harley Street. Every session, you and me.
The device is positioned over your head. Nothing is injected, nothing is swallowed, nothing is cut.
Targeted magnetic pulses to the areas involved in mood regulation, executive function, emotional control and cognitive clarity. No pain, just a gentle buzzing sensation.
Your check-in with me. We look at what your wearable, your sleep and your recovery have been doing since the last session.
No downtime is required. You carry on with your day.
There are medical reasons this kind of stimulation is not suitable for some people. That is what the screening questionnaire is for, and it is why I check before I accept anyone. If you are under medical care or taking regular medication, tell me when you apply and we will look at suitability properly.
Six sessions of brain stimulation sit in the middle of this. Around them sits the measurement, and that is the part most people have never had. From your first email to the day I read your results with you, the whole programme runs 6 to 10 weeks.
A few lines to dralka@dralkapatel.com, saying you are interested and telling me about the aspect of your brain health you most want to improve and why.
Curiosity, no commitmentI send you a short questionnaire covering eligibility, suitability and your health background. The fee is confirmed in writing here, before anything is booked.
If you meet the criteria and safety eligibility, I offer you a place. You receive a payment link to secure your place with times and dates confirmed to suit you.
You receive two test kits at home to be done before your first brain stimulation session. A biological age test, which is a finger-prick blood test, and a cortisol rhythm test, which is a saliva test, both done across one 24-hour day. Your HRV wearable provides continuous data.
60 minute session. 30 minutes with Exomind stimulation. 30 minutes with me. Memory and attention testing alternate weeks. We discuss your health, habits and highest priorities. We read your numbers together as they come in.
One visit a week for six weeks, easy to slot into a fixed diary.
Memory and attention checked on alternate weeks, so your cognition is tracked as it moves, not just at the start and end.
The same biological age test and the same cortisol rhythm test, repeated after the Exomind course on the same method as your baseline. Memory testing completes across the programme, three tests in total.
Week 10. A review of all your results and changes. What you have noticed, what the measurements tell us. What to do next.
A single cortisol reading tells you almost nothing. The rhythm tells you a great deal. So the test is not one sample. It is saliva collected at four points across a 24-hour period, at home, on a normal day. That maps the curve: where it rises, where it should fall, and where yours is doing something else.
We do it before the six sessions and again after, on the same method. Then we sit down and I tell you what changed and what I think it means for you.
Cortisol is not just a stress hormone. It is your wake-up, focus, energy and adaptation hormone. The pattern matters as much as the level.
Alongside your cortisol rhythm sit three more measurements. These are illustrations of the report format, so you can see what a personalised interpretation physically means. They are not anyone's result.
A finger-prick blood test, done at home. Two of them, one before and one after, on the same method. It places your biological age against your real age, and against an optimal range.
An objective memory and attention test, repeated three times across the programme on alternate weeks. It tracks short, working and visual memory, learning, recognition and verbal memory, so progress is measured rather than remembered.
Your Oura, Whoop, Apple Watch or similar is already collecting this every night. In the programme it is reviewed with me throughout, rather than only on test day, so we see recovery moving between sessions.
Seven things. Every one of them measured, and every result interpreted with you rather than handed over. That is the point of it being a case study.
One before, one after, on the same method, so we can see what actually moved.
Your full 24-hour curve, before and after. The pattern, not a single number.
Objective cognitive tracking through the programme, so it is not down to how you felt that week.
A 60 minute session each: 24 minutes of Exomind stimulation, then time with me. In person on London's Harley Street.
Six conversations with the doctor running the study. Not a coach, not a delegate.
Your Oura, Whoop, Apple Watch or similar numbers watched across the whole programme, not just on test day.
What your numbers did, what I think it means for you specifically, and what I would do next. My reading of your data, written for you, and a conversation about it.
Self funded. That covers everything above: the six Exomind brain stimulation sessions, the six consultations with me, the three memory tests, the two cortisol and biological age tests pre and post, and the interpretation and review.
Places are offered first come, first welcomed, subject to eligibility and medical suitability.

You are willing to share your wearable data throughout the programme.
You can attend sessions in person on London's Harley Street.
You will complete the testing before and after the programme.
You are comfortable with anonymised data being pooled for case study analysis. Your personal details stay confidential. Always.
Every applicant is screened for suitability before being accepted.
You are happy to be a case study, and to provide feedback and a testimonial.
You own and regularly use an Oura, Whoop, Apple or similar wearable that tracks HRV and sleep.
Email me to register your interest. You will receive a short screening questionnaire with the fee and the criteria in writing, and if you meet them, an invitation to the second stage of case selection.
Places are offered first come, first welcomed, subject to eligibility and medical suitability. The start date is confirmed at screening. This is a self-funded programme and the participation fee is GBP 1,500. Your personal details remain confidential, and any findings, test results and wearable data used for case study purposes are anonymised. This is a case study programme, not a treatment pathway for a diagnosed condition, and it does not replace the care of your own doctor.
