Scientists maybe one step closer to finding a cure for Alzheimer's after they discovered a molecule that prevents the development of the disease.
A new study, carried out in part by Cambridge scientists, claims a molecule that develops naturally in humans could break the cycle of events that leads to the condition.
Alzheimer's is caused by malfunctioning proteins called amyloid fibrils that then stick to other healthy proteins to form highly toxic clusters. It allows the disease to kill off a patient's brain cells.
However scientists claim the molecule Brichos prevents the proteins from forming these dangerous clusters.
It means they have moved one step closer to developing drugs capable of tackling the disease.
Dr Samuel Cohen, a researcher at St John's College at Cambridge University, said steps like this give him "optimism" that they will one day find a cure.
