British researchers have developed a test to detect Alzheimer's disease in its earliest stages.
It works by looking for a combination of "markers" in the blood which are different in healthy people and those with the disease.
Delegates at the Alzheimer's Research UK Conference heard that the University of Nottingham is now developing a quick and easy test to do in clinics.

Adults don't always outgrow sleepwalking, and among those who don't, 58 percent may become violent and sometimes injure either themselves or their sleeping partner, a new study shows.
Not only that, these sleepwalkers suffer a host of health problems during their waking hours, the researchers noted.

People who have suffered anorexia for years and failed to respond to conventional treatment could be effectively treated by a "pacemaker-in-the-brain", researchers have found.
Doctors used electric pulses delivered deep into the brain to prevent weight loss in several women who had suffered the eating disorder for decades.
Although the pilot trial was only designed to assess safety, the results suggest the technique might offer new hope to the most seriously affected patients.

Scientists have raised the prospect that deep brain stimulation could help people suffering from severe anorexia nervosa.
In the small Canadian study three people were able to gain weight and had improvements in their overall mood after undergoing the procedure.
The researchers say larger trials are now needed to show whether this therapy could provide a last resort for people with difficult-to-treat anorexia.
The study is published in the Lancet.
Researchers from the Krembil Neuroscience Centre and University Health Network in Canada conducted the study primarily to find out whether this procedure is safe in people with severe cases of the eating disorder anorexia nervosa.

Alzheimer's Disease Drug Shelved After Trial Failure
Two US drug firms say they will stop development of an Alzheimer's drug because it failed in two late-stage clinical trials.
Bapineuzumab, made by Pfizer and Johnson & Johnson, was designed to halt build-up of plaque in the brain.
But it failed to improve cognitive or functional performance compared with a placebo in certain patients. Read More
Being overweight is not just bad for waistlines but for brains too, say researchers who have linked obesity to declining mental performance.
Experts are not sure why this might be, but say metabolic changes such as high blood sugar and raised cholesterol are likely to be involved.
Obesity has already been tipped as a risk factor for dementia. Read More
Anxiety and Even Suicide Risk Higher Than for Other Spouses
When Linda Green recalls her husband John's 2009 heart attack, her heart races and her hands get sweaty.
"It feels like posttraumatic stress," she says. "I just relive it all."
Though she says she held up well during her husband's hospital stay, Green says she became anxious and depressed when the crisis was over and his recovery was under way.
Her experience is not unique.
