Ear Issues Linked to Higher Dementia Risk
20 Apr
Summary
- Middle-ear conditions like cholesteatoma raise dementia risk.
- Eardrum perforations double the risk of developing dementia.
- Surgical treatment may slightly reduce dementia risk.

Common ear conditions may be associated with an elevated risk of dementia, according to recent research. A Columbia University study analyzed data from over 300,000 U.S. adults to explore the link between middle-ear problems and dementia.
The research identified specific conditions, including cholesteatoma (abnormal middle ear skin growth) and eardrum perforation, as significantly correlated with increased dementia risk. Cholesteatoma was linked to 1.77 times the odds, while eardrum perforation showed more than double the risk.
While otosclerosis did not show a significant association, the study authors noted that dementia risk decreased slightly when surgical treatment was performed for cholesteatoma and eardrum perforation. This adds to evidence suggesting cognition is affected by sensory deprivation.
Experts emphasize that the study shows an association, not direct causation. However, the findings align with the idea that hearing loss can lead to social disengagement, a factor known to increase dementia risk. Maintaining social interaction and auditory function may therefore be crucial for cognitive health.
