Imbalanced hearing is more than a mild disability

Researchers at Washington University School of Medicine in St. Louis have received a five-year, $3 million grant from the National Institutes of Health (NIH) to study the effects of asymmetric hearing loss in adults and children.

Asymmetric hearing is a difference between the two ears’ ability to detect and process sound. New studies indicate that people with asymmetric hearing experience greater communication difficulties than previously assumed.

Plaques Detected in Brain Scans Forecast Cognitive Impairment

Brain imaging using radioactive dye can detect early evidence of Alzheimer's disease that may predict future cognitive decline among adults with mild or no cognitive impairment, according to a 36-month follow-up study led by Duke Medicine.

The national, multicenter study confirms earlier findings suggesting that identifying silent beta-amyloid plaque build-up in the brain could help guide care and treatment decisions for patients at risk for Alzheimer's. The findings appeared online March 11, 2014, in Molecular Psychiatry, a Nature Publishing Group journal.
