Alzheimer’s & Brain Awareness Month (June)
Alzheimer’s & Brain Awareness Month is June 1–30, 2027. The Alzheimer’s Association organizes it each June to raise awareness of Alzheimer’s and other dementias and to encourage brain health.
Purple is the official color of the Alzheimer’s movement, and many people wear purple during June (Alzheimer’s News Today).
What is The Longest Day?
The Longest Day is the Alzheimer’s Association’s fundraising event held on or around the summer solstice, the day with the most daylight of the year. In 2027, the June solstice falls on Monday, June 21, so The Longest Day is expected on or near that date.
Participants pick an activity they love, such as hiking, gaming, cooking, or a party, and raise money to fight Alzheimer’s. The association’s Solstice Challenge also asks people to log 16 hours of physical activity in June, finishing by the solstice (Alzheimer’s News Today). The association confirms each year’s date on its website.
World Alzheimer’s Month (September)
World Alzheimer’s Month is September, led by Alzheimer’s Disease International (ADI) and national Alzheimer’s societies around the world. Its center point is World Alzheimer’s Day on September 21, which falls on a Tuesday in 2027.
The 2026 campaign theme was “The Earlier You Know, The More You Can Do: A Dementia Diagnosis Matters” (The Alzheimer Society of Ireland). The 2027 theme has not been announced.
National Alzheimer’s Disease Awareness Month (November)
National Alzheimer’s Disease Awareness Month is November in the United States. President Ronald Reagan first proclaimed November 1983 as National Alzheimer’s Disease Month in Proclamation 5110, signed on September 30, 1983 (American Presidency Project).
November is also National Family Caregivers Month, so many groups use the month to recognize the families who care for people with dementia.

Ways to take part
You can take part in any of the three months. Ideas from the Alzheimer’s Association and other groups include:
- Go purple: wear purple or add a purple frame to your profile picture in June.
- Join The Longest Day: choose an activity on or around June 21, 2027, and fundraise for Alzheimer’s research and care.
- Learn the warning signs: memory loss that disrupts daily life is not a normal part of aging, and early diagnosis helps families plan.
- Support a caregiver: offer a family caregiver a few hours of respite, a meal, or help with errands, especially in November.
- Look after your brain: regular exercise, sleep, and social connection are part of brain health campaigns each June.
Other health months in 2027, including Mental Health Awareness Month in May, are listed in the Awareness Calendar 2027.
