Li J, Xu X, Deng X, Li S, Guo T, Xie H. Association of Vestibular Disorders and Cognitive Function: A Systematic Review. Laryngoscope 2024. [PMID: 39016124 DOI: 10.1002/lary.31646] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Revised: 05/25/2024] [Accepted: 07/01/2024] [Indexed: 07/18/2024]
Abstract
OBJECTIVES The purpose of this study is to consolidate and condense the available evidence about the potential association between vestibular diseases and cognitive impairment. DATA SOURCES AND METHODS A systematic search was conducted on four English databases (PubMed, Embase, Web of Science, Cochrane Library) from the time of library construction to March 2024. The study incorporated various keywords such as "vestibular disorders," "vertigo," "dizziness," "Meniere's disease," "benign paroxysmal positional vertigo," "vestibular migraine," "vestibular neuritis," "labyrinthitis," "bilateral vestibular disease," as well as "cognitive function" and "cognitive dysfunction." A qualitative review was conducted to look for and assess pertinent studies. RESULTS A total of 45 publications were incorporated, encompassing prevalent vestibular disorders, mostly targeting individuals in the middle-aged and older demographic. The findings indicate that individuals with vestibular disorders experience varying levels of cognitive impairment, which is evident in different aspects, with visuospatial cognitive deficits being more prominent. Furthermore, patients with chronic vestibular syndromes are more prone to cognitive dysfunction. Lastly, the hippocampus plays a crucial role in the intricate vestibular neural network. CONCLUSION The findings of this comprehensive review indicate that vestibular disorders can result in impairments across various aspects of cognitive functioning, particularly in visuospatial cognition. The underlying mechanism may be associated with a decrease in the size of the hippocampus. Individuals suffering from chronic vestibular dysfunction exhibit a higher likelihood of experiencing cognitive deficits. LEVEL OF EVIDENCE NA Laryngoscope, 2024.

Vestibular dysfunction leads to cognitive impairments: State of knowledge in the field and clinical perspectives (Review). Int J Mol Med 2024; 53:36. [PMID: 38391090 PMCID: PMC10914312 DOI: 10.3892/ijmm.2024.5360] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2023] [Accepted: 01/08/2024] [Indexed: 02/24/2024] Open
Abstract
The vestibular system may have a critical role in the integration of sensory information and the maintenance of cognitive function. A dysfunction in the vestibular system has a significant impact on quality of life. Recent research has provided evidence of a connection between vestibular information and cognitive functions, such as spatial memory, navigation and attention. Although the exact mechanisms linking the vestibular system to cognition remain elusive, researchers have identified various pathways. Vestibular dysfunction may lead to the degeneration of cortical vestibular network regions and adversely affect synaptic plasticity and neurogenesis in the hippocampus, ultimately contributing to neuronal atrophy and cell death, resulting in memory and visuospatial deficits. Furthermore, the extent of cognitive impairment varies depending on the specific type of vestibular disease. In the present study, the current literature was reviewed, potential causal relationships between vestibular dysfunction and cognitive performance were discussed and directions for future research were proposed.

Abstract
Vestibular disorders are prevalent and debilitating conditions of the inner ear and brain which affect balance, coordination, and the integration of multisensory inputs. A growing body of research has linked vestibular disorders to cognitive problems, most notably attention, visuospatial perception, spatial memory, and executive function. However, the mechanistic bases of these cognitive sequelae remain poorly defined, and there is a gap between our theoretical understanding of vestibular cognitive dysfunction, and how best to identify and manage this within clinical practice. This article takes stock of these shortcomings and provides recommendations and priorities for healthcare professionals who assess and treat vestibular disorders, and for researchers developing cognitive models and rehabilitation interventions. We highlight the importance of multidisciplinary collaboration for developing and evaluating clinically relevant theoretical models of vestibular cognition, to advance research and treatment.

Abstract
Delirium is an acute brain dysfunction. As one of the common psychiatric disorders in ICU, it can seriously affect the prognosis of patients. Hormones are important messenger substances found in the human body that help to regulate and maintain the function and metabolism of various tissues and organs. They are also one of the most commonly used drugs in clinical practice. Recent evidences suggest that aberrant swings in cortisol and non-cortisol hormones might induce severe cognitive impairment, eventually leading to delirium. However, the role of hormones in the pathogenesis of delirium still remains controversial. This article reviews the recent research on risk factors of delirium and the association between several types of hormones and cognitive dysfunction. These mechanisms are expected to offer novel ideas and clinical relevance for the treatment and prevention of delirium.

Abstract
BACKGROUND Cognitive deficits have been defined in patients with bilateral and unilateral vestibular loss. OBJECTIVE To investigate cognitive functions in patients with episodic vestibular disorders. METHODS Nineteen patients with Meniere's disease (MD), 19 patients with vestibular migraine (VM) and 21 age and education matched healthy controls were studied. Mini Mental State Examination assessing global mental status, Reading Span Test and the Stroop Test evaluating working memory, cognitive processing, reading comprehension and attention, Trail Making Test and Benton's Judgment of Line Orientation Test investigating visual processing, visuospatial skills, processing speed were used. Beck depression and anxiety inventories were given to evaluate the emotional status. RESULTS Cognitive test results of the MD and VM patients were not significantly different from the healthy controls (p > 0.05) as well as Beck depression scores (p = 0.14). Beck anxiety scores showed significant difference (p = 0.003). VM patients had significantly higher scores than the healthy controls (p = 0.002) on pairwise comparisons. The scores of the MD patients did not reach statistical significance (p = 0.15). CONCLUSION Episodic vestibular disorders like MD and VM without inter-ictal vestibular deficits do not seem to be associated with cognitive impairment. Patients with VM have significantly higher anxiety scores than the healthy controls and MD patients.
