Dementia Detection FAQs

Posted in , by Echelon Health

Dementia is a condition that affects over 55 million people worldwide, profoundly impacting individuals, families and communities. It refers to symptoms that affect cognitive functions such as memory, thinking skills and reasoning, making everyday tasks increasingly difficult. With its prevalence on the rise, dementia has become one of the most pressing global health challenges today.

Early detection is crucial in managing the condition effectively. For people living with this disease, identifying it at its earliest stages not only allows for timely intervention and treatment but also provides them and their families with much-needed clarity. Early diagnosis opens doors to better planning, access to therapies, practical and emotional support and the ability to make informed lifestyle changes that could slow the progression of this disease and improve quality of life.

This Dementia Detection FAQs guide answers common questions about symptoms, assessments, and advancements in diagnosis.

This blog will address some of the most frequently asked questions about dementia, including its detection, diagnosis and assessment methods. We will also highlight the groundbreaking Gold Standard Dementia Assessment offered by our Harley Street clinic at Echelon Health – a pioneering step forward in providing the world’s first definitive answers for dementia diagnosis.

What is Dementia and How is it Diagnosed?

Dementia is a collective term for symptoms that affect cognitive functions such as memory, thinking and reasoning, severely impacting daily life. It can be caused by various underlying conditions, including Alzheimer’s disease and vascular dementia.

Traditional diagnostic methods for dementia detection include:

  • Cognitive Testing: To assess memory, language and problem-solving abilities.
  • Medical History Evaluation: To identify risk factors and possible dementia symptoms.
  • Imaging Scans: Such as (e.g., MRI or CT) to detect changes in brain structure.

What are the Most Common Misconceptions About Dementia?

There are many misconceptions about dementia, which can delay diagnosis and cause unnecessary fear and confusion. These include:

“Dementia is a Normal Part of Ageing”

Despite ongoing dementia research, many people believe it is an inevitable part of ageing. The reality is that while ageing increases the risk of dementia, it is not a guaranteed part of growing older. Adopting a healthy lifestyle can help reduce the risk and improve overall brain health, and early detection can make a significant difference.

“Memory Loss is the Only Symptom of Dementia”

Another common misconception is that memory loss is the only symptom of dementia. In reality, dementia affects multiple cognitive functions, including language, reasoning and problem-solving. These symptoms often start subtly, such as difficulty finding the right words, struggling to follow conversations or trouble with planning and decision-making. Recognising these early signs is crucial, as dementia is far more complex than memory decline.

“Nothing Can Be Done After a Dementia Diagnosis”

Similarly, many believe that nothing can be done once dementia is diagnosed. However, early diagnosis opens the door to interventions and lifestyle changes that can significantly slow the progression of this disease and significantly improve the quality of life for patients. Treatments such as cognitive therapies, medications and tailored care plans can help individuals maintain independence for longer and provide families with much-needed guidance and support.

“Genetic Testing Can Predict Alzheimer’s Disease for Everyone”

Many people assume that genetic testing can reliably predict whether they will develop Alzheimer’s disease. In reality, genetic testing is only recommended for families with a history of young-onset familial Alzheimer’s disease, a rare inherited form of the condition that typically develops before the age of 65. For most other types of dementia, genetic testing is unreliable and cannot provide definitive answers.

“Frontotemporal Dementia is the Same as Alzheimer’s Disease”

Another common misconception is that all types of dementia present the same way, with memory loss as the primary symptom. In reality, other forms of dementia, such as frontotemporal dementia (FTD), are often misunderstood. Unlike Alzheimer’s, FTD primarily affects behaviour, personality and language rather than memory, particularly in individuals under the age of 65. Symptoms can include sudden changes in mood, inappropriate social behaviour or difficulty with speech and comprehension.

When Should You Have a Dementia Assessment?

Recognising the early signs of dementia and seeking an assessment promptly can make a significant difference in dementia diagnosis and care. While occasional forgetfulness is a normal part of life, consistent or worsening symptoms may indicate something more serious.

What are the Early Warning Signs of Dementia?

  • Memory Loss: Forgetting recent events, names, or important dates and repeatedly asking the same questions.
  • Confusion: Becoming disoriented in familiar places, struggling to follow routines or losing track of time.
  • Language Difficulties: Trouble finding the right words, following conversations or understanding written or spoken information.
  • Problems with Planning or Decision-Making: Difficulty managing finances, preparing meals or completing tasks that require concentration.
  • Changes in Mood or Behavior: Increased irritability, withdrawal from social activities or noticeable personality changes.

When Should You Seek Help?

  1. Concerns from Family Members: Loved ones may notice changes in behaviour, memory or communication that you might not recognise yourself. If family or close friends express concern, it is wise to consider an assessment.
  2. Noticing Symptoms in Yourself: If you are experiencing persistent memory lapses, confusion, or difficulty performing everyday tasks, it is important to take these signs seriously and seek professional advice. Trust your instincts if something feels “off” in your cognitive abilities.
  3. Age-Related Risk Factors: While dementia is not a guaranteed part of ageing, the risk increases for individuals over the age of 60. If you have a family history of dementia or other risk factors such as cardiovascular disease or diabetes, it is recommended to be proactive and schedule an assessment.

A memory clinic offers specialised assessments and support for individuals experiencing cognitive difficulties, helping to identify conditions such as dementia at an early stage.

As more research highlights the benefits of early detection, it becomes increasingly clear that timely assessments are key to better outcomes. A recent survey conducted during Dementia Action Week revealed that 91% of people affected by dementia recognised clear benefits to receiving a diagnosis, with many expressing a wish that they had been diagnosed earlier.

How Accurate Are Dementia Assessments?

The accuracy of dementia assessments depends on the tools and technologies used to evaluate cognitive health. While no single traditional test can diagnose dementia definitively on its own, combining multiple diagnostic methods increases reliability and provides a more comprehensive understanding of a person’s cognitive function.

The Reliability of Cognitive Tests

Cognitive tests are often the first step in assessing dementia. These tests measure aspects such as memory, problem-solving attention and language skills. Common cognitive assessments include:

  • MMSE (Mini-Mental State Examination):
    • One of the most commonly used tools to screen for dementia.
    • It assesses functions such as orientation (date and location), short-term memory and simple problem-solving.
    • While helpful, MMSE may not detect early or mild forms of dementia, as it primarily targets more obvious cognitive impairments.
  • MoCA (Montreal Cognitive Assessment):
    • MoCA is a more sensitive tool compared to the MMSE, particularly for detecting mild cognitive impairment (MCI), an early stage of dementia.
    • It evaluates memory, attention, executive function and visuospatial abilities.
  • ACE-III (Addenbrooke’s Cognitive Examination):
    • Known for its high sensitivity (97%), the ACE-III assesses five cognitive domains: attention, memory, fluency, language and visuospatial ability.
    • Its comprehensive nature makes it an excellent tool for detecting dementia at earlier stages.

While cognitive tests are reliable for identifying cognitive decline, they have limitations. For instance, results can sometimes be influenced by factors such as education level, language barriers or anxiety during testing. These tests are best used as part of a multi-modal assessment to ensure accuracy.

The Role of Advanced Imaging Technologies

Traditional cognitive tests alone are not sufficient to provide a definitive dementia diagnosis. This is where advanced imaging technologies, such as MRI and PET scans, play a critical role.

  • MRI (Magnetic Resonance Imaging):
    • MRI scans provide detailed images of brain structure, helping to identify physical changes such as brain shrinkage (atrophy), a common indicator of dementia.
    • They are particularly useful for detecting vascular dementia or brain damage caused by small strokes.
  • PET Scans (Positron Emission Tomography):
    • PET scans go beyond structural imaging and highlight changes in brain activity and metabolism.
    • Amyloid PET scans, for example, can identify the buildup of amyloid plaques, a hallmark of developing Alzheimer’s disease, years before symptoms appear.

By combining cognitive tests with imaging techniques, clinicians can achieve greater accuracy in diagnosis, especially when identifying early stages of dementia. Advanced imaging allows for the detection of subtle changes in the brain that may not yet manifest in noticeable symptoms.

Advancements in Multi-Modal Assessments

The most accurate dementia assessments today utilise a multi-modal approach, combining several tools to eliminate guesswork.

  • Cognitive Testing identifies functional deficits.
  • Advanced Brain Imaging provides insights into structural and functional brain changes.
  • Blood Biomarker Tests can reveal inflammation, nutrient deficiencies, or early signs of cognitive decline.
