Hearing loss and dementia are priorities in public health due to their high prevalence among older adults. Many studies of recent years have suggested association between cognitive decline and presbycusis. Amelioration of hearing difficulties via aural rehabilitation can potentially slow down cognitive decline. The change may not be extensive but is statistically signifi cant. Therefore, testing of auditory function should be included in assessment of demen-ted patients and patients with suspected dementia, in order to gain a holistic overview of their status and to help manage the disease.
