Frequently asked questions
Is Alzheimer's inherited?
Most cases are not directly inherited, though family history and genes raise the risk somewhat. Rare early-onset forms can run strongly in families. A healthy heart and active lifestyle help lower risk.
Does treatment slow it down?
There is no cure, but some medicines can ease symptoms for a period, and good support, activity and management of other health problems help people live well for longer.
