Dear Dr. Hibberd:
My father and one of my grandfathers both suffered from dementia before they died. Does this run in families and is there anything I can do to stop it?


Answer:
Unfortunately, people with a family history of dementia are at greater risk of developing it. However, many people with a family history never develop symptoms, and many people without a family history do. Tests are available to determine whether you have such genetic mutations. To reduce your risk, avoid alcohol, quit smoking, keep blood pressure, cholesterol, blood sugar levels as close to normal as possible.
