Statins help to reduce the risk of heart disease by lowering levels of cholesterol which clog up the blood vessels.
It is thought that a poor supply of blood to the brain may be one factor which promotes the development of dementia.
Therefore, if statins help keep the blood vessels healthy, and blood flowing freely to the brain, they may help protect against the disease.
However, it is still not clear exactly how statins work on the biochemical pathways involved in dementia.
Professor Haan said one possibility is that statins may help to reduce levels of the hormone insulin, which have also been implicated in the development of dementia.
