FRIDAY, Nov. 28 (HealthDay News)—The adult children of people with the rarer, inherited form of Alzheimer’s disease are being sought for a new study to better understand the biology of the brain disorder.

Three hundred adults with a biological parent diagnosed with a known genetic mutation causing the rare, early-onset form of Alzheimer’s are needed for the six-year, $16 million study being funded by the U.S. National Institute on Aging. The Dominantly Inherited Alzheimer’s Disease Network (DIAN) study aims to identify the sequence of brain changes that occur even before symptoms begin to appear. By understanding this process, researchers hope to also gain insight into the more common late-onset form of Alzheimer’s.

People interested in participating in the DIAN study should visit www.dian-info.org. Study participants must be aged 18 or older.
