Evaluation of the montreal cognitive assessment in idiopathic tinnitus patients with mild hearing loss
Objective:To explore the effect of mild hearing loss on cognitive function by evaluating the Mont-real Cognitive Assessment(MoCA)in idiopathic tinnitus patients with mild hearing loss.Methods:102 patients with idiopathic tinnitus(68 patients with normal hearing and 34 patients with mild hearing loss)whose first com-plaint is tinnitus and 34 healthy volunteers(control group)were included.All subjects were asked to fill the Mo-CA,Tinnitus Handicap Inventory(THI),Self-rating Anxiety Scale(SAS),Self-rating Depression Scale(SDS),and Pittsburgh Sleep Index(PQSI)after collecting medical history,pure tone audiometry,tinnitus matching and masking test.The clinical characteristics and scores of each scale were compared among the groups.Results:The score and each dimension score of MoCA in idiopathic tinnitus patients with normal hearing were significantly low-er than the normal population(P＜0.05);compared with patients with idiopathic tinnitus with normal hearing,patients with mild hearing loss were older(P＜0.01)and had lower MoCA scores(P＜0.05).There was no sig-nificant difference in MoCA scores(P＞0.05)between tinnitus patients with normal hearing and mild hearing loss after correcting confounding factors(age,gender,years of education,duration of tinnitus,frequency of tinnitus tones,side of tinnitus,THI score,SAS score,SDS score,and PQSI score);idiopathic tinnitus patients with mild hearing loss scored significantly lower in attention and working memory dimensions than idiopathic tinnitus pa-tients with normal hearing(P＜0.01).Conclusion:Patients with idiopathic tinnitus may have cognitive dysfunc-tion,and mild hearing loss may not be a factor that promotes the further aggravation of cognitive dysfunction in patients with idiopathic tinnitus.The role of hearing loss in cognitive dysfunction in patients with idiopathic tinni-tus needs further research.
