Seems that caffeine has neuroprotective effects beyond just keeping the lights switched on upstairs:
Coffee may cut the risk of dementia by blocking the damage cholesterol can inflict on the body, research suggests.
The drink has already been linked to a lower risk of Alzheimer’s Disease, and a study by a US team for the Journal of Neuroinflammation may explain why.
A vital barrier between the brain and the main blood supply of rabbits fed a fat-rich diet was protected in those given a caffeine supplement.
“Caffeine appears to block several of the disruptive effects of cholesterol that make the blood-brain barrier leaky,” said Dr Jonathan Geiger, who led the study.
“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.”
