Memory Loss & Alzheimer's

Last reviewed 28 October 2026 · Editorial policy

Memory loss is forgetfulness that goes beyond the usual. Normal aging does not cause dramatic memory loss. Alzheimer's disease is the most common form of dementia and affects memory, thinking and behavior. If you are a family member or caregiver reading this for someone else, this page is for you too.

Common options

  • A medical checkup. Memory loss has many causes, including low vitamin B12, medicines and depression. Treatment depends on the cause.
  • Prescription medicines that may slow how fast symptoms get worse or help with behavior problems. The benefit may be small.
  • Staying physically, mentally and socially active, and eating a diet rich in omega-3 fats.
  • Memory aids at home, such as written schedules for medicines, familiar photos or music.
  • Making the home safe and, later, looking at extended-care options if daily tasks become hard.
  • Caregiver support groups to ease stress and isolation.

When to see a doctor

  • Memory problems or other changes in thinking begin.
  • There is a sudden change in thinking or alertness.
  • Symptoms are getting worse.
  • You can no longer care for the person at home. If you can, go to visits together, because doctors often ask family about symptoms.

Research studies

Researchers are studying new ways to diagnose and treat memory loss and Alzheimer's disease. A clinical study is one option to discuss with a doctor.
