Two European research teams have identified three genes that affect a person’s risk of developing Alzheimer’s disease, the most common cause of dementia in the elderly.
The new genes appear to have at least as big a role as four others discovered in the past 15 years that are known to play a role in Alzheimer’s.
The new findings, reported Sunday in the journal Nature Genetics, will have no immediate consequence in either diagnosis or treatment of the disease. However, they will help illuminate a process that goes on for years or even decades before memory loss, the cardinal symptom of the disease, becomes apparent.
