Other things to consider
Reducing dementia risk factors doesn’t guarantee that you will never develop dementia. But it does mean that, at a population level, fewer people will be affected. Recent estimates suggest that up to 35% of all dementia cases may be due to the risk factors outlined above.
This figure also includes management of hearing loss, although the evidence for this is less well established.
The contribution of sleep disturbances and diet to dementia risk are emerging as important, and will likely receive more consideration as the evidence base grows.
Even though dementia may be seen as an older person’s disease, harmful processes can occur in the brain for several decades before dementia appears. This means that now is the best time to take action to reduce your risk.
