Background and Aim: Subjective tinnitus is a phantom auditory perception caused by different factors and affects the patient’s quality of life. The tinnitus pathophysiology is not fully understood; therefore, there is no effective treatment for tinnitus. Along with other methods, auditory evoked potentials (AEPs) may be helpful in understanding this condition and the involved structures. This study aimed to review the applications of AEPs in tinnitus studies.
Recent Findings: The studies investigating tinnitus were categorized into three groups of tinnitus pathophysiology, pre- or post-treatment/intervention evaluation of tinnitus, and objective diagnosis of tinnitus. Contradictory and unrepeatable findings were observed in each group.
Conclusion: Discrepancies in the results of AEPs studies can be due to between-group and within-group differences, lack of proper matching in terms of tinnitus etiology and hearing loss, and difference in neurophysiologic models of tinnitus.
Background and Aim: Age related changes in cognitive functioning have been shown to vary depending on the task used. Thus, the study aimed to compare the responses of young and older adults to an auditory Stroop test that assessed spatial (responses to location of the stimuli) and semantic (responses to meaning of the stimuli) localization.
Methods: The “Auditory spatial and semantic localization Stroop test”, developed as a part of the study was administered on 30 young adults aged 18 to 30 years and 30 older adults aged 58 to 70 years having normal hearing. The response accuracy and reaction time of the participants were determined for the words “right”, “left”, “front”, and “back.”
Results: The older adults had significantly poorer response accuracy and reaction time than the young adults for both spatial and semantic localization tasks. Within each participant group, semantic localization had better response accuracy than spatial localization, while such differences in reaction time were found only in the older adults. In both groups, a congruency effect was seen for spatial but not for semantic localization when response accuracy was calculated, whereas it was observed only for semantic and not for spatial localization when reaction time was measured.
Conclusion: The auditory Stroop test, which measures stimulus interference and cognitive skills, could be used as a simple tool to assess the same for stimuli presented through the auditory modality. This would be especially helpful in older adults who may demonstrate cognitive decline with ageing to auditory stimuli.
Background: In December 2019, the first Coronavirus disease 2019 (Covid-19) case was observed in Wuhan, China, and afterward, the world has been exposed to an ongoing pandemic. The Covid-19 has different symptoms, such as fever, coughing, shortness of breath, muscular pain, headache, diarrhea, nose running, and a sore throat. However, the symptoms of Covid-19 are not limited to these ones.
The Case: The present study reports a 39-year-old female patient complaining of earache and hearing loss with no other Covid-19 symptoms. The medical tests and diagnoses finally inferred that she was suffering from the Covid-19.
Conclusion: In addition to the common symptoms of Covid 19, acute otitis media can be considered as another symptom of this disease.
