Our brain is a very important organ which is sensitive to its environment and therefore sensitive to how well we take care of it.

OverviewMy Brain Health PlanDementiaKey messages


Did you know – 40% of cases of dementia can be prevented if we look after our brains.


  • Learning new things and education, starting as early as possible. More learning helps with brain stimulation so that even as your brain cells start to deteriorate when you get older, you will be less likely to experience dementia symptoms
  • Having plenty of positive social interactions increases and maintains brain activity as well as being good for your mental wellbeing
  • Keeping active means more blood gets to the brain and helps keep a healthy blood pressure (which also prevents heart attacks and strokes). 30 minutes of exercise a day, or 2.5 hours a week, is enough to keep things working well
  • Not smoking – smoking has a negative effect on brain health in several ways. The toxins cause stress to the brain itself and cause increased blood pressure and narrowing of blood vessels in the body and the brain
  • Having a healthy diet, especially if you are diabetic. Moderating sugars and carbohydrates and being a healthy weight helps the brain and the heart’s ability to pump blood and oxygen to the brain
  • Managing alcohol Too many units of alcohol a week increases your risk of developing dementia and high alcohol intake causes a particular type of brain damage
  • Getting enough sleep. Sleep is when your brain does a lot of its own healing and flushes out toxins, so trying to get between 7-9 hours a night is a key to keeping a healthy brain
