Every September, World Alzheimer’s Month brings global attention to Alzheimer’s disease and other forms of dementia. This annual campaign, led by Alzheimer’s Disease International, encourages people, communities, and organizations to come together to improve awareness, reduce stigma, and support those living with memory loss.

What is Alzheimer’s Disease?

Alzheimer’s disease is the most common type of dementia, a condition that affects memory, thinking, and behaviour. Symptoms often begin with mild forgetfulness and can progress to challenges with daily activities, communication, and independence. Alzheimer’s is not a normal part of aging—it is a brain disorder that requires medical care and community support.

Why World Alzheimer’s Month matters

  • Awareness: Understanding the early signs of Alzheimer’s can lead to earlier diagnosis and better support.
  • Stigma reduction: Talking openly about dementia helps reduce shame and isolation for individuals and families.
  • Support for caregivers: Millions of caregivers worldwide provide unpaid care. This month recognizes their efforts and highlights the need for better resources.
  • Global action: With aging populations, dementia is one of the most urgent health and social care challenges of our time.

How to recognize signs of Alzheimer’s

If you are concerned about memory loss in yourself or a loved one, some early signs to look for include:

  • Frequent forgetfulness or misplacing items
  • Difficulty completing familiar tasks
  • Confusion about time or place
  • Challenges with words, conversations, or judgment
  • Withdrawal from social activities
  • If these symptoms sound familiar, it’s important to talk to a healthcare professional.

What can you do to prevent Alzheimer’s?

While there is currently no cure for Alzheimer’s disease, research shows that healthy lifestyle habits can support brain health:

  • Stay physically active with regular exercise
  • Eat a balanced diet, such as the Mediterranean or MIND diet
  • Keep socially connected with family and friends
  • Challenge your mind with reading, puzzles, or learning new skills
  • Manage heart health by controlling blood pressure, cholesterol, and diabetes

How you can get involved

  • Wear purple or share information online to show your support
  • Join a local Alzheimer’s walk or awareness event
  • Reach out to someone caring for a loved one with dementia
  • Learn more from trusted resources such as Alzheimer’s Disease International or your national Alzheimer’s societyWorld Alzheimer’s Month is a reminder that dementia affects us all—whether directly or through loved ones, friends, or neighbors. By increasing awareness, reducing stigma, and supporting research, we can create a more compassionate world for people living with Alzheimer’s disease.
