World Alzheimer’s Day 2025: A Future of Prevention, A Present of Care

In 2025, it is especially critical as more than 55 million people worldwide are living with dementia, with nearly 10 million new cases every year (WHO). This rising trend places immense pressure on families, caregivers, and healthcare systems, making it essential to focus on awareness, early diagnosis, and global collaboration for better care and research.

What Is Alzheimer’s Disease?

Alzheimer’s disease is a progressive neurological disorder and the most common cause of dementia, leading to a decline in memory, thinking, and behaviour severe enough to interfere with daily life. Unlike normal age-related forgetfulness, such as occasionally misplacing keys or struggling to recall a name, Alzheimer’s involves persistent and worsening memory loss, confusion, and difficulty performing routine tasks. The disease is marked by key neurological changes: abnormal deposits of amyloid plaques (sticky protein fragments that build up between nerve cells) and tau tangles (twisted fibres inside neurons), both of which disrupt communication between brain cells and eventually cause them to die. Over time, these changes shrink brain tissue, particularly in areas critical for memory and reasoning, making Alzheimer’s far more debilitating than typical ageing.

History of World Alzheimer’s Day

World Alzheimer’s Day is a global initiative dedicated to raising awareness about Alzheimer’s and dementia, highlighting the importance of early detection, care, and research. It has evolved into a cornerstone of global advocacy within World Alzheimer’s Month.

• 1994 – First Observance: Initiated by Alzheimer’s Disease International (ADI) to mark its 10th anniversary.

• Purpose: Created to fight stigma, increase public understanding, and encourage early diagnosis and care support.

• Integration into Alzheimer’s Month: Over time, 21 September became the central day within World Alzheimer’s Month, observed every September.

• Global Participation: Governments, NGOs, and communities worldwide joined to organise campaigns, seminars, and support drives.

• Current Relevance: Today, it stands as a key moment for advocacy, driving policy changes, funding for research, and spreading awareness to millions of families affected by dementia.

Significance of World Alzheimer’s Day

World Alzheimer’s Day holds global importance as it brings together communities, caregivers, policymakers, and researchers to unite against the growing challenge of dementia. It serves as a reminder that awareness, compassion, and action can make a real difference.

• Raising Awareness

Helps reduce stigma and misinformation around Alzheimer’s and dementia.

• Encouraging Early Diagnosis

Promotes the importance of recognising symptoms early for better management.

• Supporting Caregivers

Highlights the struggles and needs of families and caregivers, ensuring they receive support.

• Driving Research and Policy

Inspires governments and organisations to invest in research, treatments, and healthcare infrastructure.

• Global Solidarity

Strengthens international collaboration and solidarity in the fight against Alzheimer’s disease.

Theme of World Alzheimer’s Day 2025

The theme for World Alzheimer’s Day 2025 is “Ask About Dementia. Ask About Alzheimer’s.” It highlights the need to break stigma by encouraging open conversations, early diagnosis, and greater awareness. The theme shapes global campaigns through educational drives, memory screenings, and support programmes that empower families, caregivers, and communities. By urging people to ask questions and seek guidance, it unites healthcare providers, policymakers, and advocacy groups in building stronger support systems and advancing the fight against Alzheimer’s disease.

The Growing Impact of Alzheimer’s Worldwide

• Alzheimer’s disease contributes to about 60-70% of all dementia cases worldwide. (WHO)

• The global cost of dementia care is estimated at US$1.3 trillion annually, with projections to exceed US$2.8 trillion by 2030 (ADI)

• Every year, nearly 10 million new dementia cases are reported globally (WHO)

• In India’s population aged 60 and above, the dementia prevalence is estimated at 7.4%, which translates to about 8.8 million people living with dementia. (Case Study https://pubmed.ncbi.nlm.nih.gov/36637034/)

• By 2050, a growing share of dementia cases will be in low- and middle-income countries, rising from ~60% today to about 71% (ADI)

Prevention of Alzheimer's: What We Know and Why It Matters

Alzheimer’s disease cannot yet be cured, but research shows that its risk can be reduced through proactive lifestyle choices and awareness of contributing factors. While genetics and age remain the strongest risk determinants, evidence shows that daily habits can influence brain health. Understanding prevention is crucial, not only because Alzheimer’s is the most common cause of dementia worldwide but also because delaying its onset by even a few years could significantly reduce its global impact.

• Healthy Lifestyle Choices

Regular physical activity, balanced diets like the Mediterranean or DASH diet, and maintaining a healthy weight have been shown to lower risk.

• Cognitive Engagement

Keeping the brain active through reading, learning new skills, or problem-solving activities can strengthen cognitive reserve and delay decline.

• Managing Chronic Conditions

Proper management of diabetes, hypertension, and cardiovascular disease reduces the chances of Alzheimer’s since vascular health is closely linked to brain health.

• Mental and Social Well-being

Reducing stress, avoiding isolation, and fostering social connections help protect against cognitive decline.

• Avoiding Risk Factors

Limiting smoking, alcohol abuse, and exposure to head injuries further reduces the risk of developing dementia-related conditions.

The Role of Caregivers of Alzheimer’s Patients

While Alzheimer's is a disease that majorly affects the elderly, it also impacts their subsequent families as they require specialised care. Here are the roles and challenges faced by the caregivers of Alzheimer's patients:

• Family and professional caregivers provide daily support that’s essential for Alzheimer’s patients: managing medications, helping with hygiene and meals, supervising mobility, and adapting to changes in behaviour or cognition.

• As Alzheimer’s progresses, caregiving becomes more complex—caregivers often deal with behavioural symptoms (agitation, confusion), communication difficulties, and increased physical demands.

• Emotional, psychological, and financial burdens are common. Many caregivers report burnout, anxiety, depression, loss of personal/social life, and role conflict (balancing caregiving with work or family) as major stressors.

Global Initiatives and Policies for Alzheimer’s in 2025

Here are the global initiatives and policies that have helped in the battle against Alzheimer’s in 2025:

• The World Health Organisation (WHO)’s Global Action Plan on the Public Health Response to Dementia (2017-2025) has been extended to 2031, recognising that many of its original targets are not yet met, especially in light of ageing populations and increasing dementia burdens.

• The WHO Action Plan focuses on several priority areas: raising awareness and prioritisation of dementia; reducing risk; improving diagnosis, treatment and care; supporting caregivers; strengthening information systems; and boosting research and innovation. (World Health Organisation)

• The Pan American Health Organisation (PAHO), in collaboration with Alzheimer’s Disease International (ADI), has launched the “Time to Act on Dementia” campaign in the Americas, aimed at addressing stigma, misinformation, and promoting earlier diagnosis and better care. (Pan American Health Organisation)

• Alzheimer’s Association globally continues to invest heavily in research: as of 2025, it has committed over US$430 million in more than 1,100 active projects across 56-57 countries, spanning multiple aspects of dementia science—from prevention to patient care.

Reducing Stigma and Raising Awareness: Participating in World Alzheimer’s Day

Here are some meaningful ways individuals, communities, and organisations can participate in World Alzheimer’s Day (21st September) in 2025:
