There was a significant correlation between the values measured by the tinnitus handicap inventory, visual analogical scale (annoyance) and loudness matching in the evaluation of tinnitus. The selection of any one of the three evaluative methods for tinnitus investigation provides different dimensions of the tinnitus and complements the others.
O zumbido, som percebido pelo indivíduo sem que haja estímulo externo, resulta da interação dinâmica de centros do sistema nervoso central, incluindo vias auditivas e não auditivas. O resultado desta interação, especialmente sistema límbico e sistema nervoso autônomo, seria responsável pelo desencadeamento de associações emocionais negativas e reações de incômodo em pacientes com zumbido. A ansiedade, condição fisiológica inerente ao ser humano, quando exacerbada gera um transtorno de humor, comprometendo o pensamento, o comportamento e a atividade psicológica. Se um estímulo interno ou externo for interpretado como perigoso ou ameaçador, desencadeará uma reação emocional caracterizada como estado de ansiedade. Este artigo tem como objetivo realizar uma revisão da literatura sobre a relação do zumbido e da ansiedade. Em se tratando do zumbido, a forma como o som é percebido pode ser alterado pela ansiedade, aguçando assim a sensibilidade para detectar sons que parecem uma ameaça em potencial, pois para muitos o zumbido é sinônimo de enfermidade grave. A etiologia do desenvolvimento da depressão e ansiedade pode estar relacionada ao zumbido. Muitos adquirem esse sintoma por problemas físicos e, consequentemente, desenvolvem a depressão e a ansiedade. Outros com graus diferentes de angústias adquirem o zumbido devido ao comprometimento emocional. Dessa forma, existe um vínculo entre o zumbido e problemas emocionais, mas nem sempre é fácil identificar o precursor. Estudos demonstram que pacientes acometidos pelo zumbido apresentam maior tendência ao suicídio, depressão e ansiedade. Além disso, referem o efeito aditivo da ansiedade e da depressão na qualidade de vida e no zumbido dos indivíduos.
Introduction The hormonal changes that occur during the menstrual cycle and their relationship with hearing problems have been studied. However, they have not been well explained. Objective The objective of our study is to investigate the variation in hearing thresholds in women during the menstrual cycle. Method We conducted a cohort and longitudinal study. It was composed of 30 volunteers, aged 18–39 years old, of which 20 were women during the phases of the menstrual cycle and 10 were men (control group) who underwent audiometry and impedance exams, to correlate the possible audiological changes in each phase of the menstrual cycle. Results There were significant changes in hearing thresholds observed during the menstrual cycle phases in the group of women who used hormonal contraceptives and the group who did not use such contraceptives. Improved hearing thresholds were observed in the late follicular phase in the group who did not use hormonal contraceptives and the hearing thresholds at high frequencies were better. Throughout the menstrual cycle phases, the mean variation was 3.6 db HL between weeks in the group who used hormonal contraceptives and 4.09 db HL in the group who did not use them. Conclusions The present study found that there may be a relationship between hearing changes and hormonal fluctuations during the menstrual cycle based on changes in the hearing thresholds of women. In addition, this study suggests that estrogen has an otoprotective effect on hearing, since the best hearing thresholds were found when estrogen was at its maximum peak.
Introduction Dichotic listening refers to the ability to hear different sounds presented to each ear simultaneously. Objective The aim of the present study was to assess dichotic listening in women throughout the menstrual cycle. Methods The volunteers who met the eligibility criteria participated in a dichotic listening assessment composed of three tests: 1) staggered spondaic word test; 2) dichotic digits test; and 3) consonant-vowel test. The female participants were tested during two different phases of the menstrual cycle: the follicular (days 11 to 13) and luteal (days 23 to 26) phases. The phases were confirmed by measuring serum levels of the hormone estradiol. Results A total of 20 volunteers aged 18 to 49 years participated in the study (9 females and 11 males). In test 1, only the right ear of females showed better performance during the follicular phase (high estrogen levels), compared with the luteal phase (low estrogen levels); in test 2, there were no significant differences for any of the groups; and in test 3, both males and females showed significantly better performance in their right ear compared with their left ear. Conclusion The better performance of females during the follicular phase of the cycle may indicate that estrogen levels might have an influence on dichotic listening in women.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
