Reducing your risks

If you reduce your exposure to things like concussions, smoking or general anesthesia can you reduce your risk of dementia?

Here, we rank the scientific evidence and give you the info on whether reducing your exposure to injuries, toxins and other factors may or may not protect your brain later in life.

Please note, the efficacy and safety ratings* in this section reflect the potential effectiveness to prevent dementia and the safety of doing so when reducing your exposure to these agents or events.
