Objective To investigate the impact of vestibular dysfunction on various domains of cognitive function, providing a basis for developing comprehensive vestibular-cognitive intervention strategies. Methods A total of 33 patients with confirmed unilateral vestibular dysfunction treated at Eye & ENT Hospital, Fudan University between June 2024 and December 2024. Vestibular function was assessed using vestibular evoked myogenic potential (VEMP), caloric testing, video head impulse test (vHIT), and sensory organization test (SOT). Cognitive function was evaluated using mini-mental state examination (MMSE), Montreal cognitive assessment (MoCA), Stroop color-word test, trail making test (TMT), and auditory verbal learning test (AVLT). Subjective symptoms were assessed using dizziness handicap inventory (DHI). Results In the vestibular function assessment of patients, abnormalities in caloric testing, utricle VEMP and saccule VEMP results were most common, with rates of 87.9%, 57.6%, and 66.7%, respectively; SOT abnormality primarily characterized by impaired vestibular function (21.2%). Spearman correlation analysis showed age, years of education, hearing ability, and emotional state were associated with overall or specific domains of cognitive function in patients. Greater vestibular dysfunction severity was associated with longer TMT-A time (r=0.443,P=0.010), most severe damage of short-term (r=-0.405,P=0.019) and long-term delayed recalls (r=-0.537,P=0.001). Patients with 31-60 of DHI scores showed longer TMT-A time than patients with 0-30 of DHI scores (P=0.033). Conclusions Patients with vestibular dysfunction exhibit significant impairment in low-frequency semicircular canal and utricle function, which affects attention allocation, information processing speed, and memory performance in cognitive tasks.

Objective To identity factors influencing willingness to participate in shoulder and neck rehabilitative exercise in laryngeal cancer patients after neck dissection surgery, and to provide reference for subject recruitment in research of similar kind. Methods Between December 2014 to December 2015, when study was conducted to subjects participating in shoulder and neck rehabilitative exercise in laryngeal cancer patients after neck dissection surgery, demographic and disease-related data of patients in two groups (those who were willing /unwilling to participate in the study) were retrospectively analyzed. Binary Logistic regression analysis was used to identify predictive factors influencing willingness to participate in shoulder and neck rehabilitative exercise in laryngeal cancer patients after neck dissection surgery. Results It was revealed by single factor analysis that differences of the following variables between the two groups were statistically significant: age (t=-3.12, P=0.001), whether living in solitude (χ2=4.55, P=0.030), whether currently employed (χ2=9.92, P=0.002), whether with other chronic diseases (χ2=7.91, P=0.004), and whether with radiotherapy after surgery (χ2=4.95, P=0.030); no statistical differences were found regarding tumor location, staging, or neck dissection method (P>0.05). Binary Logistic regression analysis indicated that age (OR=0.71, P=0.001), living alone (OR=0.76, P=0.005) and postoperative radiotherapy (OR=0.88, P=0.001) were predictors of patients' participation in shoulder and neck rehabilitation exercise. Conclusions Certain demographic factors may play a role in the patients' decision on whether or not to participate in shoulder and neck rehabilitation exercise. Senior patients and patients who live alone showa bigger tendency of refusing to attend the exercises. Also, postoperative radiotherapy reduces the patients' willingness in participating in shoulder and neck rehabilitation exercise.
