Genes linked to Alzheimer's disease in 'landmark' study

Scientists hope that, in future, they will be able to determine which factors put people at risk of Alzheimer's and to develop therapies that better treat the condition.

More than 40 genes have been linked for the first time to Alzheimer's disease in a "landmark" study, paving the way for better diagnosis and treatment.

Global scientists carried out the biggest research project of its kind looking at the genome (genetic material) of more than 100,000 people with Alzheimer's.
