Interest in how ageing affects attention is long-standing, although interactions between sensory and attentional processing older age are not fully understood. Here, we examined peripheral hearing selective a spatialised cocktail party listening paradigm, which three talkers spoke different sentences simultaneously participants were asked to report the sentence spoken by talker at particular location. By comparing sample of (N = 61; 55-80 years) younger 58; 18-35 adults, show that, as group, adults benefit much from preparatory spatial attention.

These results demonstrate that excellent retain ability direct attention, but deteriorates, graded manner, Thus, reductions likely contribute difficulties communicating social settings Overall, these findings relationship mild perceptual decline age.

Sensorineural hearing loss (SNHL) is a category of that often leads to difficulty in understanding speech and other sounds. Auditory system dysfunction, including deafness auditory trauma, results cognitive deficits via neuroplasticity. Cognitive impairment (CI) refers an abnormality the brain’s higher intellectual processes related learning, memory, thinking judgment can lead severe learning memory deficits. Studies have established strong correlation between SNHL CI, but it remains unclear how contributes CI. The purpose this article describe three hypotheses regarding relationship, mainstream load hypothesis, co-morbidity sensory deprivation as well latest research progress each hypothesis.

In this perspective article, the author explores connections between hearing loss, central auditory processing, and cognitive decline, offering insights into complex dynamics at play. Drawing upon a range of studies, relationship age-related processing disorders Alzheimer’s disease is discussed, with aim enhancing our understanding these interconnected conditions. Highlighting evolving significance audiologists in dual management health impairments, focuses on their role identifying early signs impairment evaluates various screening tools used context. The discussion extends to adaptations assessments for older adults, especially those diagnosed dementia, highlights objective electrophysiological tests. These tests are presented as vital assessing influence aging capabilities signal dysfunction. article underscores critical addressing challenges faced by population. calls further research improve diagnostic therapeutic strategies audiology, emphasizes need multidisciplinary approach tackling nexus decline.

The underlying neural mechanisms underpinning the association between age-related hearing loss (ARHL) and dementia remain unclear. A limitation has been lack of functional neuroimaging studies in ARHL cohorts to help clarify this relationship. In present study, we investigated correlates feature binding visual working memory with (controls = 14, mild HL 21, moderate or greater 23). Participants completed a change detection task assessing while their activity was synchronously recorded via high-density electroencephalography. There no difference accuracy scores for groups compared controls. increased electrophysiological those ARHL, particularly components indexing earlier stages cognitive processing. This more pronounced severe associated maintained binding. Source space (sLORETA) analyses indicated networks modulated by frontoparietal temporal regions. Our results demonstrate there may be involvement neurocognitive control maintain lower-order processing disrupted ARHL.

Background and Aim Hearing loss in old age is associated with cognitive decline depression. Our study aimed to investigate the relationship between hearing loss, decline, secondary depressive symptoms a sample of younger older cochlear implant candidates profound severe loss. Methods This part larger cohort designated provide information on baseline data before CI. Sixty-one from adulthood onwards (>18 years) were enrolled this study. All had symmetrical sensorineural both ears (four-frequency threshold difference no more than 20 dB, PTA). Individuals primary affective disorders, psychosis, below-average intelligence, poor German language skills, visual impairment, medical diagnosis potential impact cognition (e.g., neurodegenerative diseases,) excluded. Four-frequency thresholds (dB, PTA, better ear) collected. Using Abbreviated Profile Aid Benefit, we assessed subjective noise. Clinical subclinical Beck Depression Inventory (BDI II). Cognitive status was neurocognitive test battery. Results findings revealed significant negative association noise (APHAB subscale “Background Noise”) BDII. However, did not observe any link thresholds, depression, cognition. Additionally, differences emerged (25–54 subjects (55–75 years). Unexpectedly, further unplanned analyses unveiled correlations quiet environments (APHAB) performance [phonemic fluency (Regensburg Word Fluency), flexibility (TMTB), nonverbal episodic memory (Nonverbal Learning Test), as well aversive/loud sounds (APHAB)], [semantic word (RWT), inhibition (Go/Nogo) depression].

Conclusion Impact mood appears be independent, suggesting distinct aspects These results underscore importance considering only conventional audiometric measures like but also variables abilities during verbal communication everyday life, noisy settings.

Hearing loss (HL) in mid-life has been suggested as a risk factor for cognitive decline. It is unclear whether this relationship due to deprivation of auditory input alone, degenerative processes, or combination. Animal models are useful investigate underlying neural mechanisms human studies can be confounded by various factors. However, most animal use young animals and often exclude females. We used middle-aged guinea pigs both sexes 8 weeks conductive HL caused spatial learning memory impairments. Forty (20 M, 20 F, ~ 12 months) were tested the Morris Water Maze (MWM) assess baseline memory. In these (10 10 F) ear canal was plugged later, again assessed MWM. No deficits observed either sex. small decline body weight suggesting some stress associated with HL, although adrenal weight, corrected did not change. Our data suggest that alone does affect cognition middle-age, line recent additional factors need present.

This study aims to analyse the volumetric changes in brain MRI after cochlear implantation (CI), focusing on speech perception postlingually deaf adults. We conducted a prospective cohort with 16 patients who had bilateral hearing loss and received unilateral CI. Based surgical side, were categorized into left right CI groups. Volumetric T1-weighted obtained before one year surgery. To overcome artifact caused by internal device post-CI scan, image reconstruction method was newly devised applied using contralateral hemisphere of pre-CI data, run FreeSurfer. within-subject template estimation for unbiased longitudinal analysis, based linear mixed effect models. When analyzing cerebral CI, substantial increase superior frontal gyrus temporal (STG) volumes observed group.

Purpose: Speech recognition in noise is challenging for listeners and appears to require support from executive functions focus attention on rapidly unfolding target speech, track misunderstanding, sustain attention. The current study was designed test the hypothesis that lower function abilities explain poorer speech noise, including among older participants with hearing loss who often exhibit diminished cognitive abilities. Method: A cross-sectional sample of 400 younger-to-older adult (19 < 90 years age) community-based Medical University South CarolinaLongitudinal Cohort Study Age-related Hearing Loss were administered tasks control demands assess individual variability a card-sorting measure set-shifting/performance monitoring, dichotic listening selective attention/working memory, sustained attention, processing speed. Key word high- low-context perception-in-noise (SPIN) tests provided measures noise. SPIN scores adjusted audibility using Articulation Index characterize impact varied sensitivity unrelated reduced associations. Results: Set-shifting, listening, speed each explained unique significant variance audibility-adjusted, ( p s .001), after controlling age, pure-tone threshold average (PTA), sex, education level. effect sizes significantly when PTA, indicating also likely have audibility-adjusted recognition. Conclusions: Poor slow speed, poor memory appeared partially difficulties accounting audibility. These results are consistent premise distinct
