Some COVID-19 symptoms could be anxiety driven, show hearing scientists
Although there were twice as many reports of new hearing difficulties and tinnitus in people with confirmed and suspected COVID-19,compared to people who hadn’t had COVID-19, they found:
- The onset of new auditory symptoms coincided with COVID-19 in only a third of the people reporting the symptoms; a third didn’t know when their symptoms began; and a third said their symptoms began before the pandemic, even though all had said they didn’t have auditory symptoms in March 2019.
- More than 60 per cent of people with confirmed or suspected COVID-19 said that their toothache had also been affected by COVID-19 despite there being no evidence of an association.
- As expected, Type one symptoms were reported most commonly by the people with confirmed COVID-19. But Type two and Type three symptoms were reported most commonly by the people who suspected they had COVID-19.
The study also asked about challenges experienced during the pandemic, such as feeling lonely and anxious, lack of exercise, lack of space at home, caring for others.
They looked at the number of challenges reported relative to the number of symptoms experienced during the pandemic and found the higher the number of challenges, the more symptoms were reported.
Dr Gabrielle Saunders from The University of Manchester, who manages Manchester BRC’s Hearing Device Centre, was lead author on the study. She said: “Although there were more reports of auditory symptoms in people with confirmed or suspected COVID-19, our study provides evidence that psychosocial factors influenced what our respondents felt.
“We also found that respondents were inconsistent with their reporting of hearing symptoms over time. We think this is in part because their answers were affected by the context in which the question was asked.
“Even if the symptoms arose due to psychosocial factors, they are still real to the person experiencing them and so need to be managed – but using different therapeutic strategies than if they were directly caused by the virus.
“That is why we need to take great care in attributing any symptom to the effect of the virus, especially if we lack baseline data.
“We feel that studies which include control groups and use audiometric measures (hearing tests) in addition to self-reporting, to investigate change in auditory symptoms relative to pre-COVID-19, are urgently needed.”
