Scientists have found a memory 'masterswitch' in the brain, raising hopes of powerful new drugs for Alzheimer's and other diseases. When the switch is turned off by ageing and illness, memories fade. But when a drug is used to flick the switch back on, the brain's ability to store information dramatically improves. Triggering the switch in mice led to elderly creatures regaining the memory power of their youth, the journal Science reports.
The researchers are confident that a similar switch exists in the human brain - and say that drugs that capitalise on their discovery could be in use in ten years time. They could be used to stem the normal memory decline of old age - or improve the lot of Alzheimer's patients. With the disease affecting around 400,000 Britons and the number forecast to double within a generation, there is an urgent need for new treatments. Current drugs can halt the progression of the disease but do not work for everyone and their effects wear off over time. Read more: dailymail.co.uk

Dark chocolate 'can reduce risk of brain damage after stroke'

Dark chocolate can reduce the risk of brain damage following a stroke, a new study has found. Researchers discovered that a compound called epicatechin, commonly found in dark chocolate, protects the brain against stroke by shielding nerve cells.   A team of researchers based their findings on tests in mice and it is hoped the effects can soon be replicated in humans.
