Receiving a possible dementia diagnosis can feel overwhelming, whether you are concerned about your own memory or supporting a loved one. Many people are unsure how dementia is diagnosed, what tests are involved, or how to get a dementia diagnosis privately without long waiting times. This guide explains the dementia diagnosis process clearly, with a particular focus on private dementia assessments in the UK.
In the UK, if you think you have dementia, you have two main options: speak to your NHS GP and get an assessment that way, or book a private dementia assessment. At Dementech Neurosciences, we provide private dementia assessments and treatments. If you’re considering going down the private route for a dementia assessment but are unsure what to expect, keep reading as we explain everything you need to know about the process.
Why getting a dementia diagnosis matters
Receiving a dementia diagnosis can be a life-changing moment, but it is also a crucial step toward understanding what’s happening and taking control of the situation. Early and accurate diagnosis allows individuals and their families to access the right treatments, support services, and care planning. It can also help distinguish dementia from other conditions that may cause similar symptoms but are treatable or reversible.
Beyond medical management, knowing the diagnosis empowers people to make important decisions about their future, including finances, living arrangements, and lifestyle adjustments. It provides clarity, reduces uncertainty, and opens the door to emotional and practical support, helping patients and their loved ones navigate the journey with confidence and preparation.
Dementia symptoms vs normal ageing symptoms
Memory changes are often the most recognised symptom, but dementia can present in many different ways. If you’re unsure whether your experiencing normal ageing symptoms or dementia symptoms, here are some common comparisons between the two:
| Signs of ageing | Signs of dementia |
| Forgetting information from a while ago, such as events from hours or days past | Forgetting very recent information, asking the same questions repeatedly |
| Occasionally misplacing objects, e.g. your phone or the TV remote, but being able to find them by retracing your steps |
Placing items in unusual locations (e.g., phone in fridge) and unable to find them |
| Taking a little bit longer to learn something new, e.g. how to use a new appliance | Unable to learn new tasks or remember instructions, even after repeated attempts |
| Taking longer to plan something or critically think something through, and sometimes make decisions without thinking of the consequences first | Severe difficulty planning or thinking critically, making decisions without understanding consequences |
| Sometimes struggling to think of the right word or follow conversations where lots of people are involved | Regularly forgetting the name/word for things and finding it hard to follow conversations, even with just one person |
| Occasionally forgetting the day of the week but remembering later on | Losing track of time completely and not being able to figure it out |
| Knowing your way around familiar places but having initial difficulty in new places | Getting confused or lost in familiar places, e.g. the local shop |
When should you see a GP about dementia?
It’s normal to occasionally forget names or misplace items, particularly during periods of stress or tiredness. However, if memory problems or changes in thinking begin to interfere with daily life or seem to be getting worse over time, it’s important to speak to a GP.
You should consider booking an appointment if you or someone close to you notices ongoing issues such as frequent memory lapses, confusion about time or place, difficulty following conversations, problems managing familiar tasks, or noticeable changes in mood, behaviour, or personality. Concerns raised by family members, friends, or colleagues are also worth taking seriously, as they may notice changes that are harder to recognise in yourself.
A GP can carry out an initial assessment, review medications and physical health, and arrange further tests if needed. Seeing a GP early helps identify whether symptoms are related to dementia or another condition that may be treatable, and it allows appropriate support and referrals to be put in place as soon as possible
Understanding how dementia is diagnosed
dementia is diagnosed
There is no single test that can diagnose dementia. Instead, diagnosis involves a structured process that looks at symptoms, medical history, cognitive ability, and physical health to build a clear clinical picture.
Step-by-step dementia diagnosis process
- Initial consultation and medical history
A clinician will discuss symptoms, when they started, and how they affect daily life. Information from family members or carers is often very helpful at this stage. - Cognitive and memory tests
Standardised assessments such as the MoCA (Montreal Cognitive Assessment) or MMSE (Mini-Mental State Examination) are commonly used to evaluate memory, language, attention and problem-solving skills. - Physical examination
A physical health review helps rule out non-dementia causes of cognitive symptoms, such as infections or neurological conditions. - Blood and laboratory tests
Blood tests may be used to identify reversible causes of memory problems, including vitamin deficiencies or thyroid issues. - Brain imaging
Scans such as MRI or CT may be recommended to look for changes in brain structure, evidence of stroke, or other abnormalities. - Specialist review and diagnosis
A specialist clinician interprets all findings together to determine whether dementia is present and, if so, which type. - Feedback, care planning, and follow-up
The diagnosis is explained clearly, and next steps are discussed, including treatment options, lifestyle advice, and support services.
How to get a dementia diagnosis
NHS dementia diagnosis
Many people start by visiting their GP, who can make a referral to a memory clinic or specialist service. While NHS care is comprehensive, waiting times for assessments can be long in some areas.
Private dementia assessment
A private dementia assessment offers a faster and more flexible route to diagnosis. It is particularly suitable for individuals who:
- Want to avoid long waiting lists
- Need an urgent assessment
- Prefer longer consultation times
- Want continuity with the same specialist
Private assessments follow recognised clinical guidelines and provide a detailed, person-centred evaluation.
What happens during a private dementia assessment?
A private dementia assessment is typically thorough and unhurried. It usually includes:
- A detailed clinical interview
- Comprehensive cognitive testing
- Review of medical records and medications
- Collaboration with family or carers (with consent)
- Clear written reports and recommendations
At Dementech, we offer personalised dementia treatment plans, with care planning and ongoing monitoring.
Preparing for a dementia assessment
To make the most of an assessment, it can help to:
- Write down symptoms and when they began
- Bring a list of current medications
- Attend with a family member or carer if possible
- Note any changes in mood, behaviour, or daily functioning
Preparation helps clinicians gain a clearer understanding of the situation.
What happens after a dementia diagnosis?
Being diagnosed with dementia can bring a mix of emotions, from relief at having answers to concern about the future. After a diagnosis, the focus shifts from identifying the condition to understanding it, managing symptoms, and planning ahead.
A clinician will usually explain the type of dementia diagnosed, how it may progress, and what treatment or support options are available. In some cases, medication may be prescribed to help manage certain symptoms, alongside recommendations for lifestyle changes that support brain health, such as staying socially active, maintaining a balanced diet, and keeping mentally engaged.
Just as importantly, a diagnosis opens the door to wider support. Individuals and their families may be offered guidance on emotional wellbeing, practical adjustments at home or work, and access to specialist services or community resources. Discussions about future planning — including finances, legal matters, and care preferences — can also take place at a pace that feels appropriate.
Life after a dementia diagnosis
Life after a dementia diagnosis does not stop. Many people continue to live independently and enjoy meaningful activities for years, particularly when the condition is identified early. With the right support in place, individuals can adapt routines, focus on strengths, and maintain a good quality of life.
For families and carers, understanding the diagnosis helps them provide informed support and plan for changes over time. While the journey may involve challenges, having clarity about the condition allows everyone involved to move forward with greater confidence, preparation, and access to the right help at the right time.

Frequently asked questions around dementia diagnosis
Do I Need a Dementia Assessment?
Not every memory lapse or moment of confusion signals dementia. Mild cognitive changes can be a normal part of ageing. However, if you notice persistent or worsening symptoms, it’s important to get checked.
Signs to look out for include:
- Frequent forgetfulness or trouble recalling recent events
- Confusion or disorientation
- Difficulty completing everyday tasks, like shopping or managing money
- Struggling to find words or follow conversations
- Changes in mood or behaviour, such as increased irritability or anxiety
You don’t need to have multiple symptoms to benefit from an assessment. Even small changes are worth investigating. A dementia assessment can confirm whether your symptoms are normal ageing, a different condition, or early signs of dementia. The sooner you assess changes, the sooner you gain clarity, peace of mind, and access to appropriate support or treatment.
How long does a dementia assessment take?
The length of a dementia assessment can vary depending on the tests required and the complexity of symptoms. Typically, a comprehensive assessment may take a few hours and can include memory tests, cognitive evaluations, medical history reviews, and sometimes brain imaging or blood tests. At Dementech Neurosciences, assessments are streamlined so that results and recommendations can be delivered more quickly than in standard NHS pathways. While the process is thorough, it is designed to provide clarity as efficiently as possible.
Will my family be involved in the Assessment?
Family involvement is often an important part of a dementia assessment. Loved ones can provide valuable insights into daily behaviours, memory changes, and mood, which may not always be obvious to the individual themselves. With consent, clinicians may speak with family members or carers to ensure a more complete understanding of symptoms and challenges. This collaborative approach helps ensure the diagnosis is accurate and that any care or support recommendations are practical and effective for everyday life.
How accurate is a dementia diagnosis?
A dementia diagnosis is typically very reliable when conducted by an experienced specialist using a thorough assessment process. Accuracy increases when doctors review medical history, conduct cognitive testing, perform physical examinations, and consider input from family members or carers. Early or subtle cases may require ongoing monitoring to confirm the diagnosis.
What role do specialists play in diagnosis?
Specialists such as neurologists, geriatricians, or cognitive neuroscientists lead the assessment process. Their expertise allows them to interpret test results accurately, distinguish between different types of dementia, and develop personalised recommendations for treatment or management. Working with a specialist ensures the assessment is thorough, reliable, and tailored to your needs.
