While NHS memory services remain the most common route to a dementia diagnosis, many families consider a private dementia assessment to avoid long waiting times and gain faster access to specialist advice. These typically cost £1,000+ for a full package and can often be done within weeks rather than months.
Early diagnosis of dementia is important because it allows people and their families to plan ahead, access support sooner, and make informed decisions about care, finances and future living arrangements.
But the bad news is that according to Care England nearly one in three people wait for more than a year for a formal dementia diagnosis via the NHS, and waiting times for memory clinics can exceed two years.
Read on for everything you need to know about getting a private assessment for dementia, including all costs involved, what happens during the process and how it compares to the NHS.
What is a private dementia assessment?
A private dementia assessment is a comprehensive evaluation carried out by dementia specialists, such as consultant psychiatrists, neurologists or geriatricians. The aim is to identify whether memory and thinking changes are caused by dementia, mild cognitive impairment (MCI), or another health condition.
Some people decide to book a private assessment for dementia, either by paying for it themselves or through their private health insurance. However, it’s worth seeing the NHS GP as a first step. Once the GP has completed the initial screening, they can refer the person to a private specialist or clinic in the local area.
Most private memory clinics follow the same clinical guidelines used by the NHS and may involve a multidisciplinary team, including doctors, nurses, psychologists and radiologists.
People often choose a private dementia consultant because they want:
• Faster access to an assessment
• More flexibility around appointments
• Detailed reports and follow-up support
• Access to specialist investigations more quickly
How much does a private dementia assessment cost?
The private dementia assessment cost can vary significantly depending on the provider, location and level of testing required.
In the UK, typical costs include:
Initial consultant appointment: £400–£800
Cognitive assessment: £500+
MRI brain scan: £350–£600
Blood tests: £100–£250
Full dementia assessment package: £1,000–£3,500+
Some providers offer all-inclusive assessment packages. Current examples include services priced at around £1,295 from the Private Medical Clinic and £2,499 for a full diagnostic pathway, including consultations, cognitive testing and imaging.
If a dementia capacity assessment is required for legal matters such as a Lasting Power of Attorney or Court of Protection application, separate fees may apply. From Insight Mental Health these assessments often start at around £350–£650, although costs vary by provider.
Before booking, ask exactly what’s included. Some clinics charge separately for scans, blood tests and follow-up appointments.
What happens during a private dementia capacity assessment?
Although every private memory clinic works slightly differently, the assessment process is usually similar.
1. Initial consultation
The first appointment is typically with a dementia consultant or dementia specialist clinician.
They will discuss:
- Symptoms and when they started
- Medical history
- Current medications
- Family history
- Daily living difficulties
Family members or carers are often encouraged to attend because they may notice changes the person themselves hasn’t recognised.
2. Cognitive testing
The next step involves structured tests designed to assess memory, language, concentration, problem-solving and other thinking skills.
These assessments help specialists understand whether there are signs of cognitive impairment and which areas of the brain may be affected.
3. Physical health checks
Many conditions can cause memory problems that are not dementia.
To rule out other causes, specialists may arrange:
- Blood tests
- Blood pressure checks
- ECGs
- Medication reviews
4. Brain imaging
An MRI or CT scan may be recommended to look for changes in the brain associated with different forms of dementia.
Not everyone will need a scan, but it is common as part of a comprehensive assessment.
5. Diagnosis and report
Once all the information has been reviewed, the specialist will explain the findings and discuss whether a diagnosis can be made.
You should receive a detailed written report outlining:
- The diagnosis (if applicable)
- Recommended treatments
- Lifestyle advice
- Support services
- Follow-up care options
Private dementia assessment vs NHS: what's the difference?
Many families wonder whether paying for an appointment at a private memory clinic offers a better assessment than the NHS.
In reality, both routes are designed to follow recognise clinicial standards. The biggest differences are usually cost and waiting times.
Private assessment | NHS assessment |
|---|---|
Self-funded or insurance-funded | Free at the point of use |
Usually 1–4 week wait | Waiting times vary by area |
Faster access to scans and specialists | Access depends on local services |
Greater appointment flexibility | Fixed local pathways |
Additional cost for tests and follow-ups | Most care included |
Importantly, the two systems don’t have to be mutually exclusive. Some people pay for a private assessment but continue their treatment and ongoing support through NHS services afterwards.
Pros and cons of private dementia assessments
Advantages
- Faster diagnosis and treatment planning
- Quicker access to dementia specialists
- Flexible appointment scheduling
- Detailed reports and personalised recommendations
- Potentially faster access to scans and investigations
Disadvantages
- Significant financial cost
- Not all follow-up care may be included

The bottom line is that a private dementia assessment can provide faster access to diagnosis, specialist expertise and peace of mind.
For many people, the decision comes down to balancing the financial cost against the value of getting answers sooner. Whether you choose a private memory clinic or the NHS route, seeking help early can make a significant difference to planning treatment, support and future care.
Preparing for the appointment
It’s normal to feel anxious before a dementia assessment. Remember that the purpose is not to “pass” or “fail” a test, but to understand what’s causing the symptoms.
Before attending, try to bring:
- A list of current medications
- Details of symptoms and when they began
- Relevant medical records
- A family member or trusted friend, if possible
The more information specialists have, the more accurate the assessment is likely to be.

What happens during a private dementia assessment?
A private dementia assessment usually includes an initial consultation with a specialist, cognitive tests to assess memory and thinking skills, a review of medical history, and sometimes blood tests or brain scans. The specialist will then discuss the results and provide a diagnosis or recommendations for further investigations.

How do I find a reputable private dementia assessment service?
When choosing a private dementia assessment service, it's important to look beyond cost alone. Check that assessments are carried out by appropriately qualified specialists, such as consultant psychiatrists, neurologists, geriatricians or clinical psychologists with experience in diagnosing dementia. Look for clinics that are registered with the Care Quality Commission (CQC) in England, or the relevant healthcare regulator in Scotland, Wales or Northern Ireland. A reputable private memory clinic should be transparent about pricing, explain its diagnostic process clearly, and be willing to work alongside your GP and local NHS services to ensure continuity of care after diagnosis.
What to do next
If you’re concerned about memory changes, the next step is to speak to your GP or consider booking a private dementia assessment if you want a faster route to answers.
