closeThe question: Do antioxidant supplements -- specifically vitamins E and C -- help older people ward off dementia?
This study: It analyzed data on 2,969 people older than 65 with no cognitive impairment at the start of the study. Over the next 5 1/2 years, dementia was diagnosed in 405 people, including 289 with Alzheimer's disease. Those who regularly took vitamin C, vitamin E or both supplements were no more or no less likely to have developed dementia or Alzheimer's than were those who took neither vitamin.
Who may be affected? Older people.

Caveats: Information on supplement use was provided by the participants only at the start of the study; it did not include how long people had taken supplements. Doses were estimated.
