Various factors can affect how sharp our brain is, and how strong our memory is, but there are things you can do to support this.

Dr Marilyn Glenville, the UK’s leading Nutritonist and author of Natural Solutions for Dementia and Alzheimer’s, has offered her advice on keeping the brain strong.

She advised: “Meditation can not only help relieve stress, but also improve brain function. In one study, participants were asked to practice a guided meditation for 15 to 30 minutes a day for eight weeks. MRI scans showed not only improved functional connectivity in the default mode network but also slowed shrinkage of the hippocampus, the main part of the brain responsible for memory that usually shrinks with dementia. Participants also showed an overall improvement in cognition and wellbeing.”

And did you know that even brushing your teeth regularly may help support your memory?

Researchers at the University of California found that people who brush their teeth less than once a day might be up to 65 per cent more likely to develop dementia than those who brush it daily. This is because scientists think that the bacteria that cause gum disease may trigger an immune response in the brain, which destroys neurons and can cause symptoms such as memory loss.
