Johns Hopkins Discovers New Path to Treating Age-Related Hearing Loss – “There’s More to Hearing Than the Ear”
By JOHNS HOPKINS MEDICINE DECEMBER 24, 2022 Researchers at Johns Hopkins Medicine have found that old mice are less able than young mice to “turn off” certain actively firing brain cells in the presence of ambient noise. This results in a “fuzzy” sound stage that makes it difficult for the brain to focus on a specific sound and...

Women who have cluster headache are more affected in their daily lives, shows study
Reviewed by Emily Henderson, B.Sc. Dec 21 2022 Cluster headache, sometimes known as “suicide headache”, have been described as a predominantly male disease. New research from Karolinska Institutet in Sweden now shows that women who have the disease are more affected in their daily lives. They have longer periods of pain, a higher frequency of related symptoms,...
