Narrator: This is Science Today. By the year 2020, the number of people with Alzheimers Disease will jump from todayís figure of four million to seven million. University of California at Davis epidemiologist Calvin Hirsch says thatís because of the increased rates of longevity.
Hirsch: So now our greatest challenge for the next century in terms of disease processes is to push back the onset of Alzheimers disease to the point that it is unlikely to affect most Americans.
Narrator: Itís still speculation, but Hirsch says research has suggested people taking anti-inflammatory drugs have a lower risk of developing Alzheimers.
Hirsch: The same seems to be true for women who are either current of former users of estrogen, so both estrogen and anti-inflammatory drugs seem to have somehow, a protective role on the brain that seems to delay or prevent the development of Alzheimers Disease.
Narrator: Estrogen seems to protect neurons while anti-inflammatory drugs combat the neuretic plaque found in Alzheimers. For Science Today, Iím Larissa Branin.
