Every year on 21st September, World Alzheimer's Day is observed to increase awareness regarding Alzheimer's disease and dementia. Alzheimer's disease is the most common type of dementia. It is a type of degenerative brain disease that causes memory and cognitive functions to deteriorate. It mostly affects older people, and as per a report, 1 out of every 9 people aged 65 or above will have Alzheimer's disease.

Although the disease is common, there is very little awareness or knowledge about it. Therefore, the month of September is dedicated as World Alzheimer's Awareness Month, and 21st September is celebrated as World Alzheimer's Day around the world.

What is World Alzheimer's Day?

World Alzheimer's Day is a special day designated to talk about Alzheimer's disease and to remove the stigma around it. Many people around the world associate dementia as a normal part of aging. To challenge this perception and to spread public knowledge about all types of dementia, including Alzheimer's, we celebrate 21st September as World Alzheimer's Day.
