Scientists find clue to age-related memory loss
WASHINGTON (AP) — Scientists have found a compelling clue in the quest to learn what causes age-related memory problems.
The Aug. 21 report offers evidence that age-related memory loss really is a distinct condition from pre-Alzheimer’s — and offers a hint that what we now consider the normal forgetfulness of old age might eventually be treatable.
Researchers at Columbia University Medical Center examined brains, young and old ones, donated from people who died without signs of neurologic disease. They discovered that a certain gene in a specific part of the hippocampus, the brain’s memory center, quits working properly in older people. It produces less of a key protein.
