The raised blood pressure caused by eating too much salt may damage the arteries leading to the brain.
At first, it may cause a slight reduction in the amount of blood reaching the brain. This may lead to dementia (known as vascular dementia - memory lost).
With this condition the cells in the brain don't work as well as they should because they are not receiving enough oxygen and nutrients. However, lowering blood pressure may help to alleviate some of the problems and reduce the risk of greater damage.
If you continue to eat too much salt then, over time, the damage caused by the extra blood pressure may become so severe that the arteries burst or become completely clogged.
If this happens, then the part of the brain that was receiving the blood no longer gets the oxygen and nutrients it needs and dies. The result is a stroke, where you lose the ability to do the things that part of the brain used to control.
The best way to prevent a stroke is to stop the arteries becoming damaged. And one of the best ways of doing this is keep your blood pressure down by eating less salt.
