Having a grandparent or even a cousin with Alzheimer’s disease may raise your risk of getting it.
Many people who have lost a parent to dementia have the nagging fear they may have inherited the condition. But a study now suggests less closely related relatives with Alzheimer’s disease could be a warning sign.
Someone with two grandparents diagnosed with the condition has a 25 percent higher risk of getting it, researchers found. Two cousins with Alzheimer’s disease can raise someone’s risk by 17 percent.
