About World Alzheimer’s Day
Globally, dementia is one of the biggest challenges we face, with nearly 50 million people living with dementia worldwide. To tackle this global dementia challenge we need to work together, and to collaborate and share best practice with one another.
World Alzheimer's Day was launched at the opening of ADI's annual conference in Edinburgh on 21 September 1994 to celebrate our 10th anniversary.
World Alzheimer's Day is an initiative of ADI. Each year, ADI seeks financial support to produce and distribute World Alzheimer's Day materials around the world, enabling members to organise events in their different countries.
