Dementia 'halted in mice brains' - BBC News
The team at Duke University, in the US, showed immune cells which start attacking nutrients in the brain may be a trigger for the disease.
They say their findings could open up new avenues of research for a field that has not developed a single drug to slow the progression of the disease.
Experts said the findings offered new hope of a treatment.
