British scientists are a step closer to making drugs able to stop Alzheimer's in its tracks, after making a breakthrough in the understanding of what triggers the disease.
The team at King's College London believe they have "the most detailed picture yet" of the chain reaction of events that causes brain cells to die because of Alzheimer's.
They have even begun testing potential drugs to see if they can stop the process that leads to the cells dying, said academics at KCL's Institute of Psychiatry.

Read MoreIt is one of the negative side-affects of long-haul travel, but suffering from jet lag could soon become a distant memory for weary travellers.
Australian sleep researchers have developed a set of hi-tech "sunglasses", described as the world's first "time control" spectacles, which can imitate sunlight patterns.
The team, from Flinders University, in Adelaide, say the glasses emit a soft green glow that helps a traveller adapt to changing sleep patterns and time zones in "small steps".
It targets a part of the brain that regulates the human body-clock, by sending signals to the rest of the body that help it slowly realise it is in a different area of the world.
Read MoreThe possibility that autism is linked to traffic pollution has been raised by researchers in California.
Their study of more than 500 children said those exposed to high levels of pollution were three times more likely to have autism than children who grew up with cleaner air.
However, other researchers said traffic was a "very unlikely" and unconvincing explanation for autism.
The findings were presented in the Archives of General Psychiatry journal.

Read MoreSleeping for two hours extra a night can reduce sensitivity to pain and can be more effective than strong painkillers, according to a new study.
Scientists say ten hours of sleep a night rather than the recommended eight is more effective in reducing pain than codeine.
Researchers studied 18 volunteers over four nights and found that those who slept for 10 hours were able to keep their finger on a heat source for 25 seconds longer than those who had eight hours or fewer.
The findings, published in the journal Sleep, also revealed the effect was greater than was seen in a previous study where volunteers were given 60mg of the painkiller codeine.

Read MoreA major revision to the diagnostic "bible" -- which defines what is and what is not a mental illness -- has the final approval of the American Psychiatric Association (APA).
The approval means the final draft of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders, or DSM-5, will be official when it is published in May 2013.
Ten years in the making, the rewritten manual has been embroiled in controversy. One outspoken critic is Allen J. Frances, MD, chair of the task force that developed the previous edition, DSM-IV.
In a critique published online by Psychology Today, Frances calls the DSM-5 "deeply flawed," with "changes that seem clearly unsafe and scientifically unsound."

A 'pacemaker' has been implanted in to the brain of an Alzheimer's patient in a bid to reduce memory loss.
The device, which uses deep brain stimulation, has already been used in thousands of people with Parkinson's disease as possible means of boosting memory and reversing cognitive decline.
Now the first patient in the US has undergone the delicate surgery to try and halt the effects of dementia, which lowly robs its mostly elderly victims of a lifetime of memories and the ability to perform the simplest of daily tasks.
