Exploring associations between dual sensory impairment and neuropsychiatric disorders: Insights from a prospective cohort study in the UK Biobank
Background
Evidence of dual sensory impairment (DSI) characterized by comorbid hearing impairment (HI) and visual impairment (VI) is limited in neuropsychiatric disorders. Moreover, the underlying mechanisms remain elusive.
Methods
Using data from 169,165 UK Biobank participants, we compared cognition and mental health across the no sensory impairment, HI, VI, and DSI groups and investigated the association between the number of sensory impairments and neuropsychiatric disorders in longitudinal COX analyses. We also analyzed the associations of sensory function and its interaction with brain structure, functional connectivity, inflammatory markers, and metabolites and explored their mediating roles.
Results
DSI participants exhibited poor cognition and mental health, and had a higher risk of neuropsychiatric disorders compared to those with HI/VI alone. Both HI and VI were linked to atrophic changes in the hippocampus, thalamus, precuneus, parietal cortex, middle temporal gyrus, etc., and reduced white matter integrity. Brain regions associated with HI and VI exhibited decreased functional connectivity with other cortexes. Hearing and visual performance exhibit a significant interaction in relation to cognitive function, mental health, and metabolites. Brain structures, inflammation, and metabolic biomarkers significantly associated with HI and VI mediated the relationship between sensory impairments and cognition/mental health.
Conclusion
Compared to HI/VI alone, DSI is associated with poorer cognitive function, mental health, and a higher risk of neuropsychiatric disorders, potentially driven by the interaction between HI and VI. Additionally, HI and VI are linked to brain atrophy, reduced white matter integrity, and altered functional connectivity. Furthermore, brain structure, inflammation, and metabolic biomarkers mediate the relationship between sensory impairments and cognition/mental health.
期刊介绍:
Archives of Gerontology and Geriatrics provides a medium for the publication of papers from the fields of experimental gerontology and clinical and social geriatrics. The principal aim of the journal is to facilitate the exchange of information between specialists in these three fields of gerontological research. Experimental papers dealing with the basic mechanisms of aging at molecular, cellular, tissue or organ levels will be published.
Clinical papers will be accepted if they provide sufficiently new information or are of fundamental importance for the knowledge of human aging. Purely descriptive clinical papers will be accepted only if the results permit further interpretation. Papers dealing with anti-aging pharmacological preparations in humans are welcome. Papers on the social aspects of geriatrics will be accepted if they are of general interest regarding the epidemiology of aging and the efficiency and working methods of the social organizations for the health care of the elderly.
