What is it about?
We show that young rats with mild and "hidden" hearing loss have memory problems. They also have changes in brain structure, specifically reduced myelin—a protective covering around brain cells—in the corpus callosum, an area important for communication between brain regions. Despite changes in memory and brain structure, social behavior was not unaffected.

Why is it important?
These findings are important because they suggest that mild, perhaps even unnoticed (hidden) hearing loss, can impact brain development and memory early in life.
Perspectives
Our work provides insights into the neurobiological mechanisms linking mild hearing loss to cognitive impairment and underscores the need for early detection and intervention for mild and hidden hearing loss in children.
