Researchers have discovered that a new genetic mutation could be the root cause of early-onset Alzheimer’s, and it may protect people with a variant of a different gene that predisposes them to developing the disease. The genetic trait may help delay early onset Alzheimer’s and could offer the potential for new therapeutic targets for early-onset Alzheimer’s disease.
