The Longest Day is the day with the most light — the summer solstice. On June 20, people from across the world will fight the darkness of Alzheimer’s through a fundraising activity of their choice.

June is Alzheimer’s & Brain Awareness Month — an opportunity to hold a conversation about the brain, and share the fact that Alzheimer’s disease and other dementias are a major public health issue. Everyone who has a brain is at risk to develop Alzheimer’s, the only leading cause of death that cannot be prevented, cured or even slowed. During the month of June, the Alzheimer’s Association® asks people around the world to wear Purple and use their brains to fight Alzheimer’s disease.
