突发性耳聋伴偏头痛患者多层脑网络异常与情绪障碍的关系研究OA北大核心CSTPCD

Objective:To explore the relationship between sudden sensorineural hearing loss(SSNHL)with migraine and emotional impairments using multilayer neural network technology.Materials and Methods:We recruited 41 SSNHL with migraine patients and 47 healthy controls in this study.And all participants underwent evaluation of hearing abilities,migraine,neuropsychological assessments,as well resting-state functional brain imaging.Multilayer network analysis was computed to identify dynamic changes in brain global networks.Graph theoretical network analysis(GRETNA)was used to process blood oxygen level dependent(BOLD)data,and Pearson correlation analysis was conducted to calculate the correlation between functional MRI data and emotional impairments.Results:The two groups were well matched in age,sex and education level.The mean hearing thresholds of both ears in SSNHL patients with migraine were significantly higher than healthy controls.Moreover,the scores of anxiety and depression were significantly higher in otologic migraine patients.There was no significant difference in overall modularity between the patients and healthy controls.But significant differences of network switching rates in the right Rolandic operculum and middle cingulate cortex(MCC),left cuneus and inferior occipital gyrus(P<0.005,false discovery rate correction)were observed.Additionally,the conversion rate of MCC was negatively correlated with depression in SSNHL patients with migraine group(r=-0.41,P=0.008).Conclusions:The decrease of switching rate in SSNHL patients with migraine is closely related to depression,which helps to elucidate the neuropathological basis of emotional impairments induced by SSNHL with migraine.
