Dementia risk assessment

What a dementia risk assessment involves, the difference between risk screening and diagnosis, and what genuinely protects the brain.

Key points

  • Assessment typically includes cognitive testing, cardiovascular risk profiling (blood pressure, lipids, HbA1c), hearing review, mood screening, and bloods to exclude reversible causes such as thyroid disease and B12 deficiency.

  • Bring someone who knows you well if memory is the concern, since a collateral history is one of the most useful diagnostic tools.

  • Bloods return within days; cognitive assessment results are discussed at the appointment, and any brain imaging is reported within about a week.

  • Assessment should be led by a doctor, with memory clinic or neurology referral where cognitive testing suggests more than age-typical change.

  • APOE genetic testing is available privately but is not diagnostic and is not routinely recommended: many carriers never develop dementia and many patients are non-carriers.

About this test

Published 2026-09-27 · Next review 2027-09-27

A dementia risk assessment is really two things: a check for treatable look-alikes and risk factors, and, where symptoms exist, the start of a diagnostic pathway. The evidence-backed levers are unglamorous: treating blood pressure and hearing loss, staying physically and socially active, not smoking, and managing diabetes. It suits people with a family history seeking a prevention plan, and anyone noticing genuine change in memory or thinking.

Private GPs, memory clinics and neurologists offer assessment without referral, and concerns about actual symptoms deserve a clinical appointment rather than an online test. Waiting lists for NHS outpatient assessment remain long in much of the UK, and many of these checks are not offered on the NHS at all unless you meet strict criteria. Private clinics can usually see you within days on a self-pay basis, with no GP referral needed in most cases.

Frequently asked

Common questions about Dementia risk assessment.

Quick, plain-English answers to what people ask us most.

  • What is included in Dementia risk assessment?

    Dementia risk assessment typically brings together a group of related blood tests and/or measurements chosen to give a broad picture of a particular area of health in one appointment. Exact contents vary between providers, so it's worth checking the specific list of tests included before booking. The aim is to cover the most clinically useful markers efficiently rather than requesting each one separately.

  • Who should consider having Dementia risk assessment?

    This kind of package suits people who want a comprehensive check without multiple separate appointments, including those with relevant symptoms, family history, or simply wanting reassurance. A doctor can help you decide whether a broader panel or a more targeted set of tests is right for you. It's not usually a substitute for seeing a doctor about specific new symptoms, which may need urgent assessment.

  • Do I need to prepare beforehand?

    Many panels that include fasting bloods will ask you to avoid food for a set number of hours beforehand, and some ask you to pause certain supplements. Because requirements differ by provider and by exactly what's included, always check the specific preparation instructions given at booking. Turning up prepared avoids delays or having to reschedule part of the appointment.

  • What happens during the appointment?

    Most packages combine a blood draw with any relevant measurements or scans in a single visit, usually lasting under an hour depending on what's included. Staff will talk you through each part of the assessment as it happens. You can typically return to normal activities straight afterwards.

  • Are there any risks?

    The individual components — usually blood tests and simple physical measurements — carry minimal risk, similar to any standard blood draw or check-up. If imaging or more invasive tests are included, any specific risks will be explained to you beforehand. Overall, this type of assessment is considered low-risk for most people.

  • How long does it take to get my results?

    Blood results are usually available within a few working days, while any straightforward measurements may be discussed with you on the day. You'll typically receive a consolidated report reviewed by a doctor rather than a series of separate results. The clinic will confirm the expected timeframe when you book.

  • What happens if something comes back abnormal?

    A doctor will review any unexpected findings in the context of your overall results and history, and explain what — if anything — needs to happen next. This might mean repeating a test, arranging a further investigation, or simply monitoring over time. You'll be given a clear explanation rather than being left with a number and no context.

  • Is this available on the NHS?

    The NHS doesn't typically offer this kind of bundled, comprehensive check-up outside specific clinical indications, and individual components would usually need separate GP referrals if justified. Private clinics offer this type of assessment specifically to give a fuller picture in one visit, usually within days of booking. Cost varies by provider and depends on exactly what's included.

  • How reliable is this kind of assessment?

    The individual tests and measurements used are well-established and reliable when carried out by an accredited provider. As with any screening approach, it identifies areas that may need further investigation rather than providing a definitive diagnosis on its own. A doctor's review of the combined results is what turns individual numbers into a meaningful overall picture.

  • How do I book Dementia risk assessment?

    You can usually book directly online or by phone, often without needing a GP referral, with appointments typically available within a matter of days. It's worth confirming exactly what's included and any preparation needed at the time of booking. Get in touch with the clinic for current availability.
