Bottom Line: A population-based study using data from the National Health Insurance Research Database of Taiwan suggests hearing loss is associated with risk of dementia. The study included 8,135 patients with newly diagnosed hearing loss and an equal number of individuals without hearing loss for comparison. Among the 16,270 study participants, 1,868 developed dementia. Patients with hearing loss had a higher risk of dementia, especially those 45 to 64 years old. Six coexisting conditions also were associated with dementia risk in the present study. The authors caution causal inferences cannot be drawn from their findings.
