World Alzheimer’s Day: Can Blood Tests Predict Dementia Risks?

What is World Alzheimer's Day?

This important day serves as a platform for educating the public, reducing stigma, and promoting support for individuals and families affected by these challenging conditions. Through various activities and initiatives, World Alzheimer's Day brings together healthcare professionals, researchers, caregivers, and communities to advocate for better care, research, and understanding of dementia.

When is World Alzheimer's Day 2025?

World Alzheimer's Day is observed each year on September 21 to raise awareness about Alzheimer's disease and other forms of dementia. As part of World Alzheimer's Month, which takes place throughout September, this day will be a focal point for heightened awareness, education, and support efforts worldwide.

Theme for World Alzheimer's Day 2025

The World Alzheimer's Day theme for 2025 is “Ask About Dementia,” which encourages open conversations and questions to foster greater understanding and support.

This theme reflects the ongoing efforts to prioritise:

• Encouraging open dialogue about dementia experiences and challenges
• Empowering individuals, caregivers, and professionals with knowledge
• Reducing stigma and promoting compassionate care within communities

History of World Alzheimer's Day

The history of World Alzheimer's Day traces back to 1994 when it was first established by Alzheimer's Disease International (ADI) in collaboration with the World Health Organization.

• 1994: ADI and partners observed the inaugural World Alzheimer's Day
• Subsequent years featured annual themes spotlighting diverse aspects of dementia, from education and stigma reduction to early diagnosis and care
• 2012: World Alzheimer's Month was launched, expanding awareness initiatives to encompass the entire month of September

Why Alzheimer's Awareness Matters Now More Than Ever

As the global population ages and the prevalence of dementia rises, Alzheimer's awareness has become increasingly critical. Raising awareness is crucial for several key reasons:

• Over 55 million people worldwide are currently living with dementia, with numbers projected to increase significantly in the coming decades.
• Stigma and misinformation continue to hinder access to timely diagnosis and care.
• Emerging research breakthroughs and potential treatments make public education and early intervention more important than ever.
• Families face immense emotional and financial challenges in providing care for loved ones with dementia.

Facts about World Alzheimer's Day

World Alzheimer's Day brings together various stakeholders to shine a light on the realities of living with dementia and the importance of united efforts to improve care and support.

Global Statistics and Impact

• Over 55 million people are currently living with dementia globally
• This number is projected to rise to 139 million by 2050, largely due to aging populations
• Alzheimer's disease is the most common cause of dementia, accounting for 60-70% of cases

Emotional & Financial Strain on Families

• Family members often provide the majority of care for individuals with dementia, leading to significant emotional stress and burnout
• Caregiving responsibilities can result in financial hardship due to reduced work hours, lost income, and out-of-pocket expenses for medical care and support services
• The emotional impact on families is profound, as they witness progressive cognitive decline and changes in their loved one's behavior and personality

Understanding Alzheimer's Disease

Alzheimer's is a progressive brain disorder that gradually impairs memory, thinking, and daily functioning.

Key points to understand about the condition include:

• Alzheimer's is the leading cause of dementia, affecting millions of people worldwide
• Early symptoms often include forgetfulness, confusion, and difficulty with familiar tasks and routines
• The disease profoundly impacts not only the diagnosed individual but also their family members and caregivers

What Happens in the Brain During Alzheimer's?

• Abnormal deposits of proteins (amyloid plaques and tau tangles) accumulate in the brain
• These deposits disrupt normal brain cell function and communication
• Affected brain regions, particularly those involved in memory and thinking, experience progressive cell loss and atrophy

Alzheimer's vs. Normal Ageing

• Alzheimer's: Persistent, worsening memory loss that disrupts daily life; confusion with time or place; difficulty completing familiar tasks; changes in mood and behaviour
• Normal ageing: Occasional forgetfulness but ability to recall later; slower processing speed but maintained daily functioning and reasoning skills

Early Signs and Symptoms You Shouldn't Ignore

Recognising the early signs of Alzheimer's is crucial for timely diagnosis and intervention. While occasional forgetfulness is a normal part of ageing, persistent changes in memory, thinking, and behaviour warrant medical attention.

Common Early Symptoms

• Memory loss that disrupts daily life
• Difficulty planning or solving problems, including challenges with familiar tasks
• Confusion with time or place
• Trouble finding the right words in conversations or while writing
• Misplacing items frequently and struggling to retrace steps
• Withdrawal from work, hobbies, or social activities
• Changes in mood, personality, or behaviour, such as increased anxiety, depression, suspicion, or apathy

When to Seek Medical Help

• If memory lapses or confusion are interfering with everyday activities and routines
• When familiar tasks, such as driving or managing medications, become difficult or unsafe
• If family, friends, or colleagues express concerns about changes in memory, behaviour, or personality
• Whenever there are worries or questions about cognitive health

Diagnostic Tests for Alzheimer's Detection

Diagnosing Alzheimer's involves a comprehensive evaluation to rule out other potential causes and accurately identify the condition.

Key components of the diagnostic process include:

• Cognitive assessments
• Brain imaging tests
• Blood biomarker tests

Cognitive Assessments

• Tests of memory, attention, language, problem-solving, and other cognitive domains to evaluate the degree and pattern of impairment
• Commonly used tools include the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA)

Brain Imaging Tests

• Magnetic resonance imaging (MRI) or computed tomography (CT) scans to assess brain structure and rule out other conditions like tumors or strokes
• Positron emission tomography (PET) scans to visualize abnormal protein deposits or patterns of brain activity associated with Alzheimer's

Blood Biomarker Tests

• Emerging blood tests that measure levels of specific proteins (e.g., beta-amyloid, tau) linked to Alzheimer's pathology
• These tests show promise in aiding early detection and risk assessment but are not yet widely adopted in routine clinical practice

How to Participate in World Alzheimer's Day 2025

There are numerous ways for individuals and communities to get involved in World Alzheimer's Day 2025 and contribute to the global effort to raise awareness and support those affected by dementia.

Join Global Awareness Events

• Donate to funds that provide resources, education, and support services to individuals and families in need

Spread Awareness on Social Media

• Use official World Alzheimer's Day hashtags to share accurate information, personal stories, and the history of World Alzheimer's Day
• Participate in social media challenges or campaigns to engage a wider audience

Tips for Supporting Brain Health

While there is no guaranteed way to prevent Alzheimer's, adopting healthy lifestyle habits can help support overall brain health and potentially reduce the risk of cognitive decline.

Mental Exercises & Healthy Lifestyle

• Engage in mentally stimulating activities and socialise regularly
• Maintain a balanced diet
• Exercise regularly
• Prioritise quality sleep and manage stress

Regular Health Checkups

• Schedule annual wellness visits and discuss any concerns
• Manage cardiovascular risk factors such as high blood pressure, cholesterol, and diabetes, as these conditions can impact brain health
