The role of auditory training in enhancement of auditory and cognitive function in aging individuals with hearing loss and cognitive decline is discussed in this article. Results of previous controlled studies and the current pilot (Angel Sound) support value for auditory training for these individuals.

The population of the developed countries is aging, thus the number of older people is increasing. At the same time the proportion of the diseases connected with the age is rising. When a person ages, his cognitive function fades away as well. Researchers have long noted that cognitive function of the elderly with defective hearing fades away faster than in normally hearing people. There are several theories explaining it, but this issue is still a matter of debate. Several researches were held recently regarding the impact of cochlear implantation on the level of cognitive function in the preoperative and postoperative periods. Controversial results were received which require further study of the issue. HI-MoCA and RBANS-H special test systems have been developed lately for the hearing impaired. These tests allow you to evaluate the change in cognitive function in people with hearing impairment, up to complete deafness. The tests are original MoCA and RBANS, but are adapted for people with hearing impairment. Thanks to these new instruments we will be studying the change of cognitive function in preoperative and postoperative periods which will allow us to evaluate the role of hearing in the decline in cognitive function of the elderly.

Age Related Hearing Loss

A number of studies have demonstrated a significant association between age-related hearing loss (ARHL) and cognitive decline. However their relationship is not clear. In this review, we focused on the etiological mechanisms between ARHL and cognitive decline to explain the nature of this relationship: 1) causal mechanisms (e.g., cognitive load hypothesis, cascade hypothesis); 2) common cause mechanisms (e.g., microvascular disease); 3) overdiagnosis or harbinger hypothesis. We conclude that no single mechanism is sufficient and hearing and cognition related to each other in several different ways. In addition, we reviewed the effectiveness of hearing intervention (e.g., hearing aids and cochlear implants) on cognition function, and the role of hearing aid use and cochlear implant depends on the relevant mechanism.

BackgroundHearing loss is a genetically and phenotypically heterogeneous disorder.ObjectivesThe purpose of this study was to determine the genetic cause underlying the postlingual progressive hearing loss in two Iranian families.MethodsWe used OtoSCOPE, a next-generation sequencing platform targeting >150 genes causally linked to deafness, to screen two deaf probands. Data analysis was completed using a custom bioinformatics pipeline, and variants were functionally assessed using minigene splicing assays.ResultsWe identified two homozygous splice-altering variants (c.37G>T and c.662–1G>C) in the CEACAM16 gene, segregating with the deafness in each family. The minigene splicing results revealed the c.37G>T results in complete skipping of exon 2 and loss of the AUG start site. The c.662–1G>C activates a cryptic splice site inside exon 5 resulting in a shift in the mRNA reading frame.ConclusionsThese results suggest that loss-of-function mutations in CEACAM16 result in postlingual progressive hearing impairment and further support the role of CEACAM16 in auditory function.

Abstract Background The impact of falls on cognitive function is unclear. We explored whether injurious falls are associated with cognitive decline in older adults, and evaluated the role of changes in psychological and physical health as mediators of such association. Methods This prospective study involved 2,267 community-dwelling participants in the Swedish National study on Aging and Care in Kungsholmen (≥60 years). Data on injurious falls (i.e., falls requiring medical attention) during each 3-year time interval of follow-up were obtained from national registers. Assessment of cognitive function (Mini-Mental State Examination[MMSE]), depressive mood (Montgomery-Åsberg Depression Rating Scale), and physical performance (walking speed) were carried out every 3 or 6 years over a 12-year follow-up. The association between falls and cognition was estimated through linear mixed effects models, and the mediating role of changes in depressive mood and physical performance was tested using mediation analysis. Results After adjusting for potential confounders, individuals who experienced injurious falls had a greater annual decline in MMSE in the subsequent time interval (β=-1.49, 95%CI:-1.84;-1.13), than those who did not. The association increased with the occurrence of ≥2 falls (β=-2.13, 95%CI:-2.70;-1.56). Worsening of walking speed and depressive mood explained around 26% and 8%, respectively, of the association between falls and cognitive decline. Conclusions Injurious falls are associated with greater cognitive decline, and this association is partly mediated by worsening of physical performance and, in a lesser extent, of depressive mood. These findings suggest that physical deficits and low mood are potential therapeutic targets for mitigating the association between falls and cognitive decline.

Dementia Syndrome

Mild cognitive impairment (MCI) and mild dementia are a clinically relevant health problem in the elderly and Alzheimer's disease being the most common neurodegenerative disorder. Furthermore, MCI and mild dementia are characterized by a deterioration of cognitive function and their diagnosis is mainly based on cognitive examination and, the prognosis of the disease seems to be an essential reason for the diagnosis, because there is a high risk of cognitive decline in the two syndromes. This review describes the effectiveness of Ginkgo biloba (EGb761®) leaf extract for the treatment of dementia syndrome and EGb761® combination therapy with other medications for symptomatic dementia. Tebonin® is a drug of plant origin based on the active ingredient “Ginkgo biloba”. This drug has shown encouraging results, improving cognitive function, neuropsychiatric disorders and consequent reduction of caregiver stress and maintenance of autonomy in patients with age-related cognitive decline, MCI and mild dementia. Nowadays, there is little evidence to support the efficacy of EGb761® combination therapy with anti-dementia drugs and, therefore, more evidence is needed to evaluate the role of EGb761® in mixed therapy.

Diagnosis Of Dementia

The role of carers is explored in the process beginning with the early detection of changes in cognitive function through to the diagnosis of dementia. Carers were not always aware of early cognitive decline before other family and friends. Forty-five per cent of initial diagnoses were made by GPs. In over 50% of cases, the sufferer had not been told their diagnosis by health professionals or carers. A quarter of carers wanted more information about dementia even after referral to specialist services. The importance of early referral and provision of sufficient comprehensive information about dementia are discussed.

Abstract ELMOD3, an ARL2 GTPase-activating protein, is implicated in causing hearing impairment in humans. However, the specific role of ELMOD3 in auditory function is still far from being elucidated. In the present study, we used the CRISPR/Cas9 technology to establish an Elmod3 knockout mice line in the C57BL/6 background (hereinafter referred to as Elmod3−/− mice) and investigated the role of Elmod3 in the cochlea and auditory function. Elmod3−/− mice started to exhibit hearing loss from 2 months of age, and the deafness progressed with aging, while the vestibular function of Elmod3−/− mice was normal. We also observed that Elmod3−/− mice showed thinning and receding hair cells in the organ of Corti and much lower expression of F-actin cytoskeleton in the cochlea compared with wild-type mice. The deafness associated with the mutation may be caused by cochlear hair cells dysfunction, which manifests with shortening and fusion of inner hair cells stereocilia and progressive degeneration of outer hair cells stereocilia. Our finding associates Elmod3 deficiencies with stereocilia dysmorphologies and reveals that they might play roles in the actin cytoskeleton dynamics in cochlear hair cells, and thus relate to hearing impairment.
