Faster brain aging linked to tinnitus in people
Cross-sectional brain recordings and prospective imaging analyses linked stronger age-related brain changes to existing tinnitus and later onset.
Limit: Tinnitus could precede the brain changes seen in the cross-sectional recordings
Edited by Boris Djordjevic · AgingResearch.News
People with tinnitus, the perception of sound without an external source, were compared with age-, sex- and hearing-matched controls in a cross-sectional observational analysis of brain activity at rest. Measures of brain activity showed stronger relationships with age in the tinnitus group than in controls.
The researchers also conducted a prospective observational analysis of structural brain scans from UK Biobank participants without tinnitus at the start. Stronger age-related declines in the density of white matter, brain tissue containing nerve fibers, were associated with later tinnitus onset. The authors interpreted the combined findings as support for accelerated brain aging as a risk factor for tinnitus.
Why it matters
Age predicts tinnitus risk beyond hearing loss; this research examines whether changes in the aging brain might help account for that link.
Caveats
The cross-sectional recordings cannot establish which came first, and the prospective associations do not establish causation. The work is a preprint and has not been peer-reviewed.
