Alzheimer's: what increases your risk and what reduces it

The key to prevention is in your hands

The risk of Alzheimer's is influenced by numerous factors, both positive and negative. But which of these factors can you influence yourself to reduce your chances?

University researchers conducted a comprehensive meta-analysis comparing hundreds of studies. Their conclusion? A significant number of Alzheimer's cases could potentially be prevented by addressing risk factors and pursuing a healthy lifestyle.

Risk factors to avoid

  • high blood pressure
  • type 2 diabetes
  • extremely high or low BMI in later life
  • depression
  • an increased homocysteine level
  • narrowing of the carotid artery (carotid stenosis)
  • fragile health

Protective factors that may help you

  • oestrogens
  • cholesterol synthesis inhibitors (statins)
  • blood pressure lowering drugs
  • non-steroidal anti-inflammatory drugs (NSAIDs)
  • folic acid
  • vitamin E and C
  • moderate alcohol consumption
  • mental exercises (memory, problem-solving ability, logical thinking)

Although there are other factors at play, researchers argue that the risk of Alzheimer's can be significantly reduced if these aspects of diet, health, medication and lifestyle are given due attention.
