Measurement

NayaScore assessment

The NayaScore assessment in Marylebone, London measures your grip strength, your heart rate variability and your thinking across twelve cognitive domains, so that a course of treatment starts from numbers rather than from impressions.

The short answer

What the NayaScore assessment measures

You cannot personalise what you have not measured. The NayaScore assessment is how we establish where you are starting from, in numbers you can see for yourself. It is taken before treatment begins and repeated during a course, so change shows up while there is still time to act on it.

Three things are measured. Grip strength, as a plain physical marker. Heart rate variability, recorded continuously by a wearable ring rather than sampled once in a clinic room. And cognitive testing across twelve domains, including attention, planning and response inhibition, reported as percentiles against people of your age and sex.

The NayaScore is a measurement tool, not a diagnostic test. It does not name a condition and it does not replace a clinical opinion. Your clinician reads it alongside your history, your symptoms and their own judgement, and will say plainly what the numbers can and cannot tell you.

Areas treated

Why we measure before we treat

You start from a measured baseline, not from a description of how you have been feeling
Twelve cognitive domains scored separately, because brain fog looks different in different people
Heart rate variability recorded continuously by a wearable ring, rather than sampled once in a clinic
Grip strength included as a plain physical marker alongside the brain measures
Repeated during a course, so a lack of progress shows up early rather than at the end
Reported as percentiles against people of your age and sex, so a raw score means something

Patient journey

What the assessment involves

Consultation & preparation

Sleep and eat as you normally would, and take your usual medication unless your clinician has said otherwise. Keep caffeine to your ordinary amount rather than skipping it or doubling it, since both distort cognitive scores. Bring your reading glasses if you use them for a screen. Book a time of day you could realistically repeat, because comparing a morning baseline with a late-afternoon retest introduces a difference that has nothing to do with treatment. Tell us about any hand or wrist injury before the grip test rather than during it.

During treatment

Before anything is treated

The assessment comes after your free consultation and before your first treatment session. That order matters. A baseline taken after stimulation has already started is no longer a baseline, and there is then nothing to compare later results against.

Grip strength

You squeeze a handheld dynamometer as hard as you can, a few times, on each side. It takes a couple of minutes. Grip is included because it is a plain physical measure that is quick, repeatable and hard to talk yourself into or out of, which makes it a useful anchor beside the brain measures.

Continuous heart rate variability

Heart rate variability is the variation in time between consecutive heartbeats, and higher variability generally indicates a nervous system that can shift between alert and settled states. You wear a ring, so the reading is continuous across your ordinary days and nights rather than a single sample taken in a clinic room on a stressful morning.

Cognitive testing across twelve domains

A set of computer-based tasks, each scoring one cognitive domain separately. Response inhibition, attention and planning are among them, and mental rotation is included as a stability check because it should not move much over a few weeks. Scores are reported as percentiles against a comparison group of your own age and sex.

Repeating it, and reading it honestly

The assessment is repeated during your course, so the question of whether treatment is working is answered with data rather than recall. Short series of measurements have real limits: practice effects and ordinary variation can both move a score. Your clinician will tell you which changes are large enough to mean something and which are not.

Aftercare

Your clinician talks the results through with you rather than sending a score and leaving you to interpret it, and will be specific about which numbers are meaningful and which sit inside ordinary variation. The ring keeps recording between appointments. The assessment is repeated during your course so progress is measured against your own baseline, and your results are kept, so a later course starts from a real history rather than from memory.

FAQ

NayaScore questions

Is the NayaScore a diagnostic test?

No. It is a measurement tool for tracking change over time, and it cannot name a condition or replace a clinical opinion. Your clinician reads it alongside your history, your symptoms and their own judgement. If what you need is a diagnosis, that is a separate conversation with an appropriate specialist.

How long does the assessment take?

Allow about an hour in the clinic for the grip testing and the cognitive tasks, plus time to fit the ring and explain what it records. The heart rate variability part then runs quietly in the background across your ordinary days. Your results are talked through with you at your next appointment.

What are the twelve cognitive domains?

A cognitive domain is a specific mental ability measured separately from the others. Attention, planning, response inhibition and mental rotation are four of the twelve tested here. Your clinician will name the full set at your assessment, and explain which of them matter most for the symptoms you came in with.

Do I have to wear the ring all the time?

Wear it as much as you comfortably can, including overnight, because sleep is where some of the most useful heart rate variability data comes from. Gaps are not a problem. If wearing it becomes uncomfortable, or you would rather not, say so, and the rest of the assessment still stands.

What if my scores do not improve?

Then you will know, and you will know early. That is the reason for measuring at all. Not everyone responds to stimulation, and repeating the same measures partway through a course means the answer arrives while decisions can still change. If the numbers are not moving, we will tell you and stop.
