Dementia is a growing global health concern, with over 55 million people currently living with the condition, and this number is expected to more than double by 2050 due to ageing populations. Despite these alarming statistics, the pathway to a clear diagnosis remains fraught with complexities. For individuals and their families, navigating the uncertainty of potential cognitive decline can be a deeply distressing experience.
One of the key challenges in diagnosing dementia lies in its diverse range of symptoms, which can vary widely between individuals and overlap with other conditions such as depression, anxiety or mild cognitive impairment. Memory loss, confusion and difficulty with everyday tasks are hallmark signs, but these symptoms can also stem from non-dementia-related issues. Moreover, the progression of dementia is often gradual, making it difficult to pinpoint when normal ageing ends and a cognitive disorder begins.
Traditional diagnostic methods, such as cognitive tests and clinical evaluations, often provide incomplete or inconclusive results. These tools may detect cognitive impairment but struggle to differentiate between various types of dementia, such as Alzheimer’s disease, vascular dementia, or Lewy body dementia. Some assessments rely on subjective observations, leading to misdiagnosis and delayed interventions.
With the growing prevalence of dementia, the demand for precise and reliable diagnostic methods has never been greater. The future of dementia care lies in groundbreaking innovations that move beyond symptom management, providing clarity and confidence to those navigating this challenging condition.
At Echelon Health, on Harley Steet, London, we are proud to lead the transformation in detecting dementia by offering the world’s first definitive Gold Standard Dementia Assessment. This pioneering approach redefines dementia diagnostics by integrating advanced imaging, neurocognitive testing and biomarker analysis to achieve exceptional accuracy.

Why Accuracy Matters in Dementia Diagnosis
Accurate and timely dementia diagnosis is critical for several reasons.
Facilitates Informed Decision-Making
A clear and accurate dementia diagnosis equips patients and their families with the knowledge they need to make meaningful and proactive decisions. From selecting the most appropriate treatments to planning long-term care and adjusting daily routines, this clarity ensures no vital step is overlooked. With an accurate understanding of the condition, individuals can tailor their lives to better manage the challenges ahead.
Enables Early Interventions
Timely and precise diagnosis opens the door to early interventions that can significantly impact the progression of dementia. From medication to cognitive therapies and lifestyle changes, these measures can slow the disease’s advancement, helping patients maintain independence and quality of life for as long as possible. Early diagnosis also allows for participation in cutting-edge clinical trials that may offer additional hope and benefits.
Provides Peace of Mind
Living with uncertainty can be as debilitating as the disease itself. An accurate dementia diagnosis removes the ambiguity, replacing it with actionable insights and a clear path forward. For patients, this clarity brings a sense of control and purpose; for families, it provides the reassurance needed to support their loved ones effectively.
Accurate dementia diagnosis serves as a vital lifeline, providing individuals with clarity to understand their condition and empowering them to take control of their future.
What Are the Current Methods for Dementia Diagnosis?
Dementia is a complex condition, and diagnosing it requires a multi-step approach to identify its type, stage and potential causes. Here is an overview of the current methods and dementia screening tests most commonly used in the UK. These dementia tests are typically conducted by a GP or a specialist at a memory clinic or hospital.
1. Clinical Evaluations
Clinical evaluations are a fundamental component of dementia assessments, offering a comprehensive understanding of the patient’s cognitive health and mental status. Typically conducted by neurologists or geriatricians, they involve two key steps:
Taking a Person’s Medical History
The primary goal of medical history is to gather essential information about the patient’s symptoms, mental abilities, dementia severity and how these impact their daily life. This includes:
- Timing and Nature of Symptoms:
The doctor will ask about when the symptoms began, how they have progressed, and any noticeable changes in behaviour, cognitive abilities or daily functioning. - Existing Medical Conditions:
A review of conditions such as heart disease, diabetes, depression, or stroke ensures these are effectively managed, as they may contribute to or exacerbate symptoms. - Current Medications:
Assessment of prescribed drugs, over-the-counter products, and supplements helps identify potential contributing factors to cognitive changes. - Caregiver Input: Input from a family member or caregiver, is often invaluable. They can provide additional context about behavioural changes or cognitive decline that the patient may not fully recognise or articulate.
Conducting a Physical Examination
The physical examination focuses on identifying signs of neurological or systemic conditions that might explain the symptoms or contribute to cognitive impairment. This includes:
- Neurological Assessments: A neurological exam checks reflexes, muscle strength, coordination and sensory responses to detect any abnormalities.
- General Physical Health Checks:
Evaluating overall health to rule out other underlying conditions that could mimic dementia, such as infections or nutritional deficiencies.
2. Cognitive Assessments
Cognitive and memory tests are designed to evaluate key mental functions, such as memory, problem-solving, language and overall cognitive skills. They help determine the presence and extent of cognitive impairment, providing an important starting point for dementia diagnosis. These pen-and-paper or verbal tests assess:
- Short- and long-term memory.
- Attention and concentration.
- Language and communication skills.
- Awareness of time and place (orientation).
Commonly used cognitive function tests include:
- General Practitioner Assessment of Cognition (GPCOG):
Often used in primary care settings in the UK, the GPCOG provides a quick evaluation of memory and thinking skills, helping to identify whether further assessment is needed. - Mini-Mental State Examination (MMSE):
MMSE is a brief 30-point questionnaire that is widely used to assess memory recall, orientation and the ability to follow simple instructions. - Montreal Cognitive Assessment (MoCA):
MoCA is a test specifically aimed at detecting mild cognitive impairment, often seen in the early stages of dementia. It evaluates a broader range of cognitive functions, such as attention, executive functioning and visuospatial skills. - Addenbrooke’s Cognitive Examination (ACE III):
ACE III is a more comprehensive test with high sensitivity for cognitive impairment. It provides detailed insights into memory, verbal fluency, and visuospatial ability, making it particularly effective in identifying early signs of dementia and distinguishing between different types of dementia.
While these tests are valuable for initial screening, they can be influenced by factors such as education level and cultural background, potentially leading to false positives or negatives. Therefore, they are often used in conjunction with other diagnostic methods, such as brain imaging and biomarker analysis, to achieve a more definitive diagnosis.
3. Blood Tests
The purpose of blood tests in a dementia screening is to rule out other conditions that may mimic dementia symptoms. Blood tests check for:
- Vitamin Deficiencies: Checking for low B12 or folate levels.
- Thyroid Function: Checking for disorders such as hypothyroidism.
- Liver and Kidney Function: To rule out metabolic issues.
- Diabetes: Using HbA1c levels.
While blood tests are standard in the UK, they are primarily used to exclude other conditions rather than directly diagnosing dementia. While not widespread, research studies and emerging diagnostic advances from around the world, such as CSF Analysis, now enable the detection of biomarkers in blood and cerebrospinal fluid providing a more direct and accurate means of diagnosing dementia at earlier stages.
Biomarker Tests
Biomarkers in cerebrospinal fluid (CSF) and blood are groundbreaking because they provide direct biochemical evidence of dementia-related changes in the brain. By detecting key markers such as beta-amyloid, tau protein, and neurofilament light, these tests enable clinicians to identify underlying disease processes with greater precision than ever before.
This groundbreaking approach improves diagnostic accuracy, enables earlier interventions and allows treatments to be tailored to the specific type of dementia, providing new hope for more effective disease management.
Although highly promising, these tests are not yet widely available for broader clinical use.
4. Brain Scans
Brain scans play a crucial role in detecting structural and functional changes in the brain that may indicate dementia. They are also used to rule out other conditions such as strokes or brain tumors. The main types of scans include:
Structural Imaging:
- MRI Scans: Provide detailed images of brain anatomy, aiding in identifying patterns of atrophy associated with different dementia types.
- They can help identify shrinkage in specific areas, such as the temporal lobes in Alzheimer’s or the frontal and temporal lobes in frontotemporal dementia.
- They can also detect blood vessel damage linked to vascular dementia.
- CT Scans: Utilised to detect structural changes such as brain atrophy or lesions and to rule out conditions such as strokes or brain tumours.
- These are less detailed than MRI scans for brain structure analysis.
Functional Imaging:
While traditional dementia assessments use MRI and CT scans to detect structural brain changes and rule out conditions such as strokes or tumours, advanced imaging technologies are setting new standards. New imaging advancements, including FDG-PET scanand SPECT scans, can now examine blood flow and metabolic activity in greater detail. These groundbreaking technologies can identify specific protein accumulations in the brain, such as amyloid plaques and tau tangles, which are hallmarks of Alzheimer’s disease, significantly enhancing diagnostic accuracy and paving the way for earlier and more targeted interventions.
- FDG-PET: Assesses glucose metabolism in the brain, highlighting areas of reduced activity indicative of neurodegeneration.
- SPECT: Evaluates cerebral blood flow, assisting in differentiating dementia subtypes.
While current dementia assessments provide valuable insights, they cannot conclusively diagnose dementia and often require a combination of tools and diagnostic methods to achieve a more accurate assessment and to differentiate between the various types of dementia, such as Alzheimer’s disease or vascular dementia.
