A nationwide study seeking a treatment to slow memory loss caused by Alzheimer’s disease is underway at Baton Rouge’s Pennington Biomedical Research Center, and researchers are seeking volunteers diagnosed with the disease.

Researchers need participants diagnosed with Alzheimer’s who have the early changes in the brain associated with the disease but do not yet have symptoms.

The Anti-Amyloid Treatment in Asymptomatic Alzheimer’s — nicknamed the A4 — study is testing a new treatment that may slow memory loss.

“For the first time, the A4 Study could offer hope and a chance for people with the earliest signs of (Alzheimer’s Disease) to fight back,” said Dr. Jeff Keller, director of Pennington Biomedical’s Institute for Dementia Research and Prevention.

One of 66 sites participating in the trial, Pennington is the only A4 research center in the three-state area of Louisiana, Arkansas and Mississippi.

The research will last up to 3½ years, according to A4study.org, the website of the national study. In addition to testing medications, the study also will examine why certain groups, such as African-Americans and Hispanics, are more susceptible to the disease.

The number of Americans living with Alzheimer’s is expected to triple from more than 5 million today to as many as 15 million in 2050, according to the Alzheimer’s Association.
