The sec­ond thing you can do is to pro­tect your brain from in­ter­nal in­jury – and that means eat­ing prop­erly.

The brain is a fa­mously hun­gry or­gan, us­ing about one-fifth of the body’s calorific in­take. Brain food is de­liv­ered by the blood via a dense mesh of ves­sels. If the blood hits a bot­tle­neck it may form a clot, caus­ing a stroke. De­pend­ing on its size and lo­ca­tion, a stroke may deal a cat­a­strophic blow, or pass by barely no­ticed. Such mi­nor strokes are called Tran­sient Is­chemic At­tacks (TIAs), but while they might not cause much prob­lem when they hap­pen, re­peated TIAs cause se­vere cog­ni­tive de­cline. Vas­cu­lar de­men­tia (as such a de­cline is known) is al­most as com­mon as Alzheimer’s dis­ease.
