Modern Dementia Testing Methods: How Diagnosis Has Evolved

Posted in , by Echelon Health

Dementia is a complex and progressive disease that affects millions of people worldwide, with devastating consequences for individuals and their families. In the UK, over 944,000 people are currently living with dementia, a number that is expected to surpass 1.6 million by 2040. Similarly, in the US, approximately 6.7 million adults aged 65 and older have been diagnosed with Alzheimer’s disease, the most common form of dementia. These figures highlight the growing urgency to improve diagnosis, treatment and care for this life-changing condition.

Early Diagnosis is Critical

Accurate and early diagnosis of dementia is critical for several reasons. It allows patients and their families to access support and plan for the future, improves treatment outcomes by enabling early intervention and provides clarity during what is often a deeply unsettling time. However, we know that traditional diagnostic methods often fall short, because they rely on incomplete data and subjective evaluations, leaving patients and their loved ones in the dark.

Fortunately, modern dementia testing methods are lowly transforming this landscape, offering more accuracy and insight into cognitive health and future treatments. From advanced imaging technologies to innovative blood biomarkers and highly sensitive neurocognitive assessments, the tools available today are revolutionising how dementia is detected and diagnosed.

Find out the exciting developments in modern dementia testing and see how Echelon Health's Gold Standard Dementia Assessement is revolutionising diagnosing dementia.

In this blog, we will explore the evolution of dementia diagnosis, from traditional methods to cutting-edge advancements and introduce the world’s first definitive Gold Standard Dementia Assessment offered by Echelon Health, which has set a new benchmark for precision and clarity in dementia care.

The Evolution of Dementia Diagnosis

Dementia diagnosis has come a long way, evolving from basic observational methods to more sophisticated technologies that offer greater precision and earlier detection. While the traditional mainstream approaches laid the groundwork, current state-of-the-art innovations are revolutionising how we detect, understand, manage and treat dementia, offering hope and enhanced quality of life to patients.

Traditional Dementia Testing Methods

Until recently, dementia diagnosis has primarily relied on cognitive tests, behavioural observations and input from family members or caregivers. These methods aim to assess an individual’s memory, reasoning, language skills and ability to perform daily tasks. Commonly used tools include the Mini-Mental State Examination (MMSE), which assesses orientation, registration (immediate memory), short-term memory (but not long-term memory) and language functioning. In the UK, the General Practitioner Assessment of Cognition (GPCOG) is widely used for a quick evaluation of cognitive function.

Can Dementia Be Accurately Detected in Patients?

According to NHS England, there is no single test for diagnosing dementia. Instead, a diagnosis is based on a combination of assessments and memory tests, which may be conducted by a GP or by specialists at a memory clinic or hospital. This process often includes reviewing the patient’s medical history, conducting physical and neurological examinations and performing cognitive assessments.

However, these traditional methods have significant limitations:

  • Subjective Results: Cognitive and behavioural assessments alone are often influenced by the skill and judgement of the healthcare professional conducting them, as well as by external factors such as stress or other medical conditions.
  • Delayed Diagnosis: Traditional dementia testing methods often identify dementia only after symptoms have significantly progressed, which reduces the opportunity for early intervention.
  • Incomplete Understanding: Without the ability to visualise changes in the brain cells or detect biological markers, these methods provide an incomplete picture of the disease’s progression and underlying causes.

While these widely used dementia assessment methods provide a foundation for understanding the cognitive decline in patients, the result is a diagnostic process which is fraught with uncertainty, leaving patients and their families without the clarity they need during such a critical time.

Advancing Research into Dementia-Causing Diseases

Ongoing research is at the forefront of efforts to find cures and effective treatments for the diseases that cause dementia, including Alzheimer’s disease, frontotemporal dementia (FTD) and dementia with Lewy bodies (DLB). These conditions, while distinct in their mechanisms and symptoms, share a devastating impact on cognitive function and quality of life. Understanding the root causes of these is key to unlocking new therapeutic possibilities.

1. Understanding the Main Causes of Dementia

Thanks to advancements in technology and global collaboration, researchers have made substantial strides in understanding how different diseases contribute to dementia:

  • Alzheimer’s Disease: Clinical trials and research have uncovered that a buildup of beta-amyloid plaques and tau tangles in the brain disrupts communication between neurons, leading to memory loss and cognitive decline. Research into targeting these proteins is paving the way for potential treatments.
  • Frontotemporal Dementia (FTD): FTD is associated with degeneration in the brain’s frontal and temporal lobes, often linked to genetic mutations. Studies are exploring how specific genes, such as MAPT and C9orf72, influence disease development and progression.
  • Dementia with Lewy Bodies (DLB): This form of dementia is characterised by abnormal deposits of alpha-synuclein protein in the brain, called Lewy bodies, which disrupt brain function. Current research focuses on reducing these protein accumulations and improving symptom management.

2. Advances in Imaging Technology

Advancements in modern imaging techniques, such as MRI (Magnetic Resonance Imaging) and PET (Positron Emission Tomography) scans, have become indispensable tools in the early detection of dementia.

  • MRI Scans: MRI allows for detailed visualisation of structural changes in the brain, such as hippocampal atrophy, which is often associated with Alzheimer’s disease. These scans help detect physical changes in brain tissue, enabling clinicians to diagnose dementia earlier and more accurately.
  • PET Scans: PET imaging focuses on the brain’s metabolic activity, helping to identify abnormal build-ups of amyloid plaques and tau proteins, hallmarks of Alzheimer’s disease. These scans provide functional insights into how the brain works, offering an additional layer of diagnostic precision.

3. Advances in Blood Biomarker Tests

Emerging blood tests are transforming dementia diagnosis by providing non-invasive and accessible ways to detect biomarkers associated with Alzheimer’s disease.

  • Key Biomarkers: Different blood tests now target proteins such as beta-amyloid and tau, which play a crucial role in the development of Alzheimer’s. Measuring these biomarkers can help assess a person’s risk of developing dementia years before symptoms appear.
  • UK Research: Projects funded by Alzheimer’s Research UK are exploring how blood-based diagnostics can be integrated into routine healthcare in the next five years, making early detection more widely available.
  • US Innovations: In the US, clinical tests such as PrecivityAD are advancing Alzheimer’s biomarker detection with exceptional accuracy, making dementia diagnosis more accessible. JAMA recently published a landmark study on the PrecivityAD2™ blood test.

4. Advances in Neurocognitive Testing

Modern neurocognitive assessments are another key advancement in dementia detection. Unlike traditional cognitive tests, these modern assessments are designed to detect subtle cognitive changes, providing clinicians with a more precise understanding of a patient’s cognitive health.

  • ACE-III (Addenbrooke’s Cognitive Examination III): The ACE-III is a state-of-the-art cognitive assessment tool with a sensitivity of 97%, making it one of the most accurate tests available for identifying early signs of dementia. It evaluates key cognitive functions, including memory, attention, language and visuospatial skills.

A timely and accurate diagnosis of neurodegenerative diseases, supported by potential dementia blood tests, could significantly improve the effectiveness of drug treatments and patient outcomes.

1. Memory Issues Impacting Daily Life:

  • Forgetting important dates, events, or appointments and needing frequent reminders.
  • Repeatedly asking the same questions or forgetting recent conversations.

2. Difficulty Completing Familiar Tasks:

  • Struggling with routine activities such as preparing meals, managing finances or following a familiar route.
  • Losing the ability to plan or organise tasks effectively.

3. Changes in Personality, Mood or Communication:

  • Increased confusion, irritability or anxiety.
  • Difficulty finding the right words during conversations or following a discussion.
  • Withdrawal from social activities or hobbies once enjoyed.

For individuals experiencing symptoms or concerned about their cognitive health, a dementia assessment offers valuable insights, reduces uncertainty and empowers patients to make informed decisions about their care and future. Taking the step to seek an assessment early can make all the difference in improving outcomes and quality of life.

Can We Reduce the Risk of Dementia?

While age and genetics are undeniable risk factors for dementia, research highlights the critical role of lifestyle in both preventing the onset of cognitive decline and managing brain health after a diagnosis. The World Health Organisation (WHO) advocates for a proactive approach to dementia prevention, which includes:

  • Staying Physically Active: Regular exercise boosts brain health by improving blood flow, reducing inflammation and supporting neuron growth. Studies show that activities such as walking, swimming or strength training can lower dementia risk by up to 30%. Aim for at least 150 minutes of moderate aerobic activity per week.
  • Adopt a Brain-Healthy Diet: Research from the Rush University Medical Center shows that nutrient-rich, anti-inflammatory diets such as Mediterranean and DASH Diets, which emphasise fruits, vegetables, whole grains, lean proteins and healthy fats, improve brain health and lower the risk of developing Alzheimer’s disease by 53%.
  • Keep Your Mind Active: Mental stimulation is crucial for maintaining cognitive reserves and delaying the onset of cognitive decline. Solving puzzles, reading, learning new skills or playing musical instruments challenge the brain and build neural connections.
  • Prioritise Sleep: Sleep is essential for brain health, as it allows the brain to clear waste products, including beta-amyloid plaques associated with Alzheimer’s disease. A small study from Washington University School of Medicine linked poor sleep to accelerated beta-amyloid buildup, a key marker of Alzheimer’s disease. Adults should aim for 7–8 hours of quality sleep each night.
  • Manage Chronic Conditions: Chronic conditions such as hypertension, diabetes and high cholesterol increase the risk of vascular dementia and Alzheimer’s disease. A comprehensive analysis in The Lancet Commission on Dementia Prevention, Intervention and Care identified managing these conditions as a critical component in preventing up to 40% of dementia cases worldwide.
  • Stay Socially Connected: New studies suggest that social isolation is a big risk factor for dementia in older adults and has been linked to an increased risk of cognitive decline and depression. Joining community groups, participating in hobby clubs or spending regular time with friends and family can significantly lower the likelihood of developing dementia.
