The first signs of the brain injury seen in Alzheimer's disease could occur as early as ten years before diagnosis, research shows.
Researchers at Lund University in Sweden studied 140 people with mild memory impairment, showing that a combination of biomarkers indicate a high risk of developing Alzheimer's in the future.
It was found that as many as 91 per cent of the patients with mild memory impairment who had the risk markers went on to develop Alzheimer's disease within the following ten years.
However, those who had the memory impairment but not the markers were not at a higher risk of getting Alzheimer's than healthy individuals.
Lead researcher Oskar Hansson stated that this is a "very important finding" that could lead to new therapies to combat the neurodegenerative condition.
"All prospective therapies have so far shown to be ineffective in stopping the disease, and many people are concerned that the pharmaceutical companies will give up their efforts in this field," he said.
"But these failures may depend on the fact that the new therapies were initiated too late."
