A COMMON cholesterol-lowering drug may be effective against Alzheimer's if given at an early stage of the disease, new research suggests.
The findings, from a study on mice, add to laboratory evidence that cholesterol-lowering statins may prevent some of the symptoms of Alzheimer's.
Earlier work by the same Canadian team showed simvastatin improved blood flow in the brains of year-old laboratory mice with Alzheimer's.
The new study found the drug also boosted learning and memory but only in younger six-month-old animals whose disease had not progressed far.
Dr Simon Ridley, from the charity Alzheimer's Research UK, said: "Many experts believe that treatments for dementia will be most beneficial if given very early in the disease process.
"While these new findings are valuable, the benefits are shown in mice and we don't know how they will bear out in humans. There is a real need to push on with research that will boost early detection and help people with dementia get more benefit."
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
