Recently, the researchers identified five new genetic triggers which they believe could help in finding out who was most at risk of developing Alzheimer's disease.

This study included 60,000 people and if the findings of this study could lead to some effective drug then it might prevent 60% of potential Alzheimer's cases.

The head of the international study, Professor Julie Williams from Cardiff University was sounding very hopeful as she believed that this study had brought them a step closer to the cure and it also made them aware about the direction to work in.

Referring to this research as a modest step forward, Professor David Ames, Director of the National Ageing Research Institute and medical adviser for Alzheimer's Australia, is of opinion that the findings of this study bring very limited knowledge which is needed to be confirmed and explored further to reach to more substantial conclusions.

In addition, he said, “Having genetic markers that can more clearly identify who is at high risk and who is at low risk might mean that if you've got experimental treatments to prevent Alzheimer's disease, you can select the high-risk population to target them with”.

Professor Tanzi believes that US healthcare system would be in a massive trouble if a better treatment for this disease is not found soon.
