Alzheimer’s disease is the most common form of dementia, which is an umbrella term used to describe general loss of memory, thinking skills and other day-to-day functions.

A hallmark of Alzheimer’s disease is gradual deterioration of memory. But it is a biological disease, which means that, besides seeing outwards symptoms such as memory loss, we can also measure the breakdown that occurs in the brain as a consequence of disease progression.

In this article, the author examines a range of issues associated with Alzheimer’s disease including:

  • Amyloid and tau
  • The role of genes
  • Diet, diabetes and obesity
  • Physical activity
  • Sleep
  • Mood
  • Cognitive reserve or resilience
  • Preventing Alzheimer’s disease
