“…The previous studies of objective hearing loss used a pure tone audiometry test, whereas the current study used self‐reported hearing measures in the longitudinal analyses 6, 7, 11. Nevertheless, a significant positive association was found between the self‐reported and objective test measure in Wave 7.…”

“…The current study built on previous longitudinal studies conducted in the United States and Wales that found that individuals with moderate and severe hearing loss were at greater risk of developing dementia 6, 7, 12, 22. Six hundred thirty‐nine adults aged 65 and older from the Baltimore Longitudinal Study of Aging were prospectively analysed over 11.9 years 7.…”

“…Separate analyses were conducted on self‐reported and objective hearing impairment. On the basis of the existing literature, it was decided a priori that age, sex, ethnicity, wealth, education, and hearing aid use were possible confounders 7, 11, 23. The following cardiovascular risk factors were also adjusted for: smoking status, diabetes mellitus, hypertension, and stroke.…”

ObjectivesTo determine whether hearing loss is associated with incident physician‐diagnosed dementia in a representative sample.DesignRetrospective cohort study.SettingEnglish Longitudinal Study of Ageing.ParticipantsAdults aged 50 and older.MeasurementsCross‐sectional associations between self‐reported (n = 7,865) and objective hearing measures (n = 6,902) and dementia were examined using multinomial‐logistic regression. The longitudinal association between self‐reported hearing at Wave 2 (2004/05) and cumulative physician‐diagnosed dementia up to Wave 7 (2014/15) was modelled using Cox proportional hazards regression.ResultsAfter adjustment for potential confounders, in cross‐sectional analysis, participants who had self‐reported or objective moderate and poor hearing were more likely to have a dementia diagnosis than those with normal hearing (self‐reported: odds ratio OR = 1.6, 95% CI = 1.1–2.4 moderate hearing; OR = 2.6, 95% CI = 1.7–3.9 poor hearing, objective: OR = 1.6, 95% CI = 1.0–2.8 moderate hearing; OR = 4.4, 95% CI = 1.9–9.9 poor hearing). Longitudinally, the hazard of developing dementia was 1.4 (95% CI = 1.0–1.9) times as high in individuals who reported moderate hearing and 1.6 (95% CI = 1.1–2.0) times as high in those who reported poor hearing.ConclusionOlder adults with hearing loss are at greater risk of dementia than those with normal hearing. These findings are consistent with the rationale that correction of hearing loss could help delay the onset of dementia, or that hearing loss itself could serve as a risk indicator for cognitive decline.

Objectives:The objective was to describe the extent to which nursing home patients had cognitive impairments and were diagnosed with dementia. Furthermore, to describe and compare multicomorbidity, health status and drug use in the three subgroups; dementia diagnosis/not referred, dementia diagnosis/referred and no dementia diagnosis/not referred to an emergency department (ED) over a one-year period. Methods: A crosssectional follow-up study was carried out in Sweden. RAI/MDS assessments were conducted on 719 patients in 24 nursing homes, of whom 209 were referred to EDs during a one-year period, accounting for 314 visits. This study involved an extensive examination of the population. Results: The 719 patients were reported to suffer from comprehensive cognitive impairments, which not accorded with the dementia diagnoses, they were significantly fewer. Cognitive decline or dementia diagnosis contributed to a significant decrease of referrals to EDs. Patients with dementia diagnosis/not referred had difficulties understanding others, as well as impaired vision and hearing. Patients with dementia diagnosis/referred usually understood messages. Low BMI, daily pain, multicomorbidity and high drug consumption occurred in all groups. Patients with no dementia diagnosis/not referred had significantly less multicomorbidity. Neuroleptica was significantly more prevalent among those with dementia diagnosis. Conclusion: Dementia remains undetected. Patients with cognitive decline and dementia are probably as sick as or even worse than others but may, due to low priority be undertreated or referrals avoided with the objective to provide good care in the setting. Observational studies are needed to identify what is done and could be done in referral situations.

The proportion of individuals prescribed psychotropic drugs was 80% in NHs and 85% in special care units for dementia. According to Olsson et al. (17), anticholinergic drugs were prescribed for approximately 20% of all NH patients and a high rate of psychotropic drug use (>=80%) was reported.Dementia is becoming a greater problem in health care globally (18), due to an increase in the number of people affected. In Sweden, the number of people suffering from dementia increased from 133, 000 to 148, 000 between 2000 and 2008 (14). Disorders such as dementia that cause cognitive impairment are common in long term institutional care. Mamhidir et al. (19) found that cognitive impairment was present in 67% of NH patients and Nordberg et al. (20) reported 62%. Such patients often exhibit symptoms that are difficult to interpret. Although they have the same illnesses as younger patients, their symptoms differ as they...
