World Alzheimer’s Day 2025

World Alzheimer’s Day 2025 is going to fall on Sunday, 21st September 2025. Alzheimer’s disease is a progressive brain disorder. It slowly damages memory, thinking, and reasoning. Over time, it affects the ability to perform daily tasks.

It is important to note that Alzheimer’s is not just normal aging. While memory lapses are common with age, Alzheimer’s disease causes a significant decline. It is the most common cause of dementia, but not the only one. Other conditions like vascular dementia or Lewy body dementia also exist. Here we have covered a gist of the World Alzheimer’s Day 2025:

World Alzheimer’s Day History & Background

World Alzheimer’s Day was first introduced in 1994 by Alzheimer’s Disease International (ADI). It marked the 10th anniversary of the organisation’s founding. Since then, 21 September is observed each year to spread awareness and call for global action.

The need for such a day became clear as dementia cases grew across the world. Alzheimer’s disease accounts for the majority of dementia cases. Before this initiative, there was very little public awareness about the condition. Families often suffered in silence.

Over the years, World Alzheimer’s Day has grown into a movement. Governments, NGOs, health organisations, and communities take part in campaigns. Activities include seminars, walks, health check-ups, and awareness drives. In 2012, Alzheimer’s Month was also introduced, extending awareness across the entire month of September.

World Alzheimer’s Day 2025 Theme

The theme for World Alzheimer’s Day 2025 is “Ask About Dementia. Ask About Alzheimer’s.” The theme underlines the power of asking questions. Many people hesitate to talk about memory loss or behavioural changes. This silence delays diagnosis and treatment. By asking simple questions about symptoms, risks, or care. Families can encourage early detection.

The theme also reminds healthcare providers to create safe spaces for discussion. When communities engage in conversations, stigma reduces. World Alzheimer’s Day 2025 aims to make dialogue a normal part of life.

Global Alzheimer’s Disease Cases

Dementia is now one of the leading public health concerns. According to recent data, over 55 million people worldwide live with dementia. A large share of these cases is due to Alzheimer’s disease.

Every year, millions of new cases are added. With populations ageing, the number of people affected is expected to rise sharply. By 2050, estimates suggest that 139 million people may live with dementia. The economic cost is also high, crossing $1 trillion annually.

Alzheimer’s Cases In India

India is witnessing a rapid rise in dementia cases. Studies show that about 7.4% of people aged 60 years and above are living with dementia. Alzheimer’s disease accounts for the majority of these cases.

This translates to millions of families affected across urban and rural areas. Rural regions often lack access to medical facilities, making detection and treatment harder. Social stigma also prevents families from seeking help early. Caregivers experience high levels of stress and poor mental health. The growing number of Alzheimer’s cases in India makes World Alzheimer’s Day 2025 especially important to raise awareness and push for stronger healthcare responses.

Alzheimer’s Disease Treatment

As of 2025, there is no complete cure for Alzheimer’s disease. However, progress has been made in treatment options.

Two drugs, lecanemab (Leqembi) and donanemab (Kisunla), are approved for early Alzheimer’s disease. These medicines target amyloid plaques in the brain, which are linked to the condition. Clinical trials show they slow the decline in memory and thinking abilities in the early stages.

Other medicines help manage symptoms. Cholinesterase inhibitors and memantine can reduce memory loss, confusion, and behavioural problems. Doctors also recommend lifestyle changes, counselling, and therapies to support patients.

Research continues to look for better treatments. Recent studies explore new drug targets like DNA repair pathways and inflammation control. Non-drug interventions such as brain exercises, diet, and physical activity are also important.
