“High levels of cholesterol are a risk factor for Alzheimer’s disease, perhaps by compromising the protective nature of the blood brain barrier.

“Caffeine is a safe and readily available drug and its ability to stabilise the blood brain barrier means it could have an important part to play in therapies against neurological disorders.”
