World Alzheimer’s Day 2025 will be observed on 21 September 2025. It is a global initiative aimed at spreading awareness about Alzheimer’s disease and other forms of dementia. The day serves as a reminder of the increasing impact this condition has on individuals, families, and communities. It also emphasizes the need for early diagnosis, better treatment options, and strong support systems for patients and caregivers.
Alzheimer’s is among the leading causes of dementia worldwide, affecting millions of people every year. Families often face not just memory loss and confusion in their loved ones but also deep emotional strain and financial challenges. Observing World Alzheimer’s Day 2025 encourages open conversations, reduces stigma, and strengthens collective efforts to improve care and understanding of dementia.
World Alzheimer’s Day 2025
World Alzheimer’s Day 2025 will be observed on Sunday, 21 September 2025. Alzheimer’s disease is a progressive neurological disorder that gradually damages memory, thinking, and reasoning abilities. As the condition advances, it hampers the capacity to manage even simple daily tasks.
It’s important to understand that Alzheimer’s is not a part of normal aging. While occasional forgetfulness is common as people grow older, Alzheimer’s causes a far more severe and consistent decline in cognitive function. It is the leading cause of dementia worldwide, though other forms such as vascular dementia and Lewy body dementia are also prevalent. Here’s a quick overview of World Alzheimer’s Day 2025:

World Alzheimer’s Day History
World Alzheimer’s Day was first observed in 1994, launched by Alzheimer’s Disease International (ADI) to mark the organisation’s 10th anniversary. The day was introduced at a time when dementia was poorly understood and rarely discussed in public spaces. Families caring for loved ones with Alzheimer’s often struggled in silence, with little awareness or support from society.
The initiative came in response to the rising number of dementia cases worldwide, with Alzheimer’s disease accounting for the majority. By dedicating 21 September each year to awareness, ADI aimed to break the stigma, encourage early diagnosis, and push for better care systems.
Over the years, World Alzheimer’s Day has grown into a global movement. Governments, health organisations, NGOs, and local communities now come together to organise awareness campaigns, medical check-ups, seminars, and walks. These efforts not only educate people but also provide much-needed support to patients and caregivers.
In 2012, the initiative was expanded further with the introduction of World Alzheimer’s Month, giving the cause an entire month of global recognition and outreach.
World Alzheimer’s Day Theme
The World Alzheimer’s Day Theme is “Ask About Dementia. Ask About Alzheimer’s.” It emphasizes the importance of asking questions and starting conversations. Many people notice signs like memory lapses or unusual behaviour but choose to remain silent, often out of fear, denial, or stigma. This silence can delay diagnosis and reduce the chances of timely treatment.
Encouraging families to ask straightforward questions about symptoms, risk factors, or care options can pave the way for early detection and better management. The theme also calls on healthcare professionals to provide safe and supportive spaces where such discussions can take place without hesitation.
When communities openly engage in dialogue, the stigma surrounding dementia and Alzheimer’s begins to fade. World Alzheimer’s Day 2025 seeks to normalize these conversations, making awareness and understanding a part of everyday life.
Global Alzheimer’s Disease Cases
Dementia has become a major global health challenge, with Alzheimer’s accounting for most cases. Over 55 million people are currently affected worldwide, and this number is expected to rise to nearly 139 million by 2050 as populations age. The financial burden is also enormous, exceeding $1 trillion annually.

Alzheimer’s Cases In India
India is facing a sharp increase in dementia cases, with nearly 7.4% of people aged 60 and above living with the condition. Alzheimer’s disease makes up the majority of these cases. This rise impacts millions of families across both cities and villages. In rural areas, limited healthcare access and lack of awareness make timely diagnosis and treatment difficult. Social stigma adds to the challenge, often delaying medical attention. Caregivers too bear a heavy emotional and mental health burden.
The rising numbers highlight why World Alzheimer’s Day 2025 is so significant for India. It serves as a reminder to strengthen awareness, encourage early diagnosis, and improve support systems.

Alzheimer’s Disease Treatment
As of 2025, Alzheimer’s Disease does not have a complete cure, but significant progress has been made in treatment and management.
Two newer drugs, lecanemab (Leqembi) and donanemab (Kisunla) have been approved for patients in the early stages. These medicines work by targeting amyloid plaques in the brain, one of the hallmarks of Alzheimer’s, and have been shown in clinical trials to slow down the decline in memory and cognitive abilities.
Apart from these, existing medicines such as cholinesterase inhibitors and memantine are used to manage symptoms. They help reduce memory lapses, confusion, and behavioural changes, thereby improving the quality of life for patients. Doctors often combine these with lifestyle modifications, counselling, and supportive therapies.
Research is actively exploring new possibilities. Current studies focus on pathways related to DNA repair, brain inflammation, and protein aggregation. Alongside drug development, non-pharmacological measures including cognitive training, balanced nutrition, and regular physical activity are being emphasized as part of holistic care.
