Coronavirus and hearing loss
Recent research has found that people who have battled coronavirus may be left with a hearing loss. In fact, in some cases, hearing loss could be one of the only symptoms of the virus.
A study looked at COVID-19 patients from 20-50 years of age. None of the participants in the study had a history of hearing loss. What they found was that all subjects had difficulty with high-frequency pure-tone thresholds, and compromised transient evoked otoacoustic emissions in the aftermath of the virus. Otoacoustic emissions or OAEs examine how the inner ear (cochlea) responds to sound.
In another study examining the virus, participants experienced vertigo and ringing in the ears (tinnitus). All participants also had a hearing loss that was usually more prominent on one side after recovery.
The studies that have looked at the connection between COVID-19 and hearing loss are small and limited. However, we are still discovering so much about this virus on an ongoing basis, and it seems clear that this will continue for a while.
We do not know enough about COVID-19 at this point. We do know that other viruses can have an effect on hearing. Viruses that are known to contribute to ear-related problems include measles, human immunodeficiency virus (HIV), and the herpes simplex virus. Viruses also have a reputation for being unpredictable.
What else could cause hearing loss?
Could treatments for COVID-19 be the source of hearing loss? Surprisingly, medications that are used to treat the severe respiratory symptoms that are a hallmark of COVID-19 could also be the culprit.
Medications can be ototoxic, which means they can impact hearing health. Ototoxicity means toxic to or may damage the ear. The list of drugs that are potentially ototoxic includes chloroquine, hydroxychloroquine, azithromycin, remdesivir, favipiravir, and lopinavir. – Bruce Y. Lee, Forbes Contributor
Coronavirus and mental health
People dealing with undiagnosed hearing loss are typically already dealing with mental health issues.
The anxiety related to trying to hear in a crowded room, and the stress of possibly being embarrassed by misinterpreting what is said, is already challenging enough. Add the additional apprehension we all feel during the COVID-19 pandemic and anxiety levels can skyrocket.
There are also other difficulties including ongoing fatigue that is a direct result of trying to lip read. This is why it’s essential to pay particular attention to family members and friends who are dealing with hearing loss issues, especially those who are undiagnosed or in denial.
Coronavirus (COVID-19) Symptoms
We are learning more and more about this virus every day and the list of symptoms appears to be growing. We do know that symptoms include: shortness of breath, a temperature equal to or over 38˚C, chills, new or worsening cough, abdominal pain, diarrhea, vomiting, loss of smell or taste, and headache. Of course, any changes to your hearing warrants a visit to your Doctor of Audiology as well. While the connection between hearing loss and coronavirus needs more research, we are discovering that there may also be an association.
Coronavirus and hearing loss
Even when you have been fortunate enough to avoid the virus, you may find other challenges if you currently have a hearing loss. Wearing masks are important to keep the virus in check as much as possible. However, if you have a hearing loss, masks can be a major communication barrier. Many people with hearing loss depend on lip-reading to communicate so wearing a mask has created an obstacle to their ability to socialize. Adding more difficulty is the muffling of voices when people speak through the mask barrier. One of the best ways to get over this hurdle is to get a mask with a window so that lip reading can continue.
Signs of depression
Depression and anxiety have been on the rise since the beginning of the COVID-19 pandemic. General instability in many areas of life brought on by the coronavirus is responsible for this ongoing trend. It is so important to monitor loved ones in light of the challenges brought on by the coronavirus. The signs of depression can include many symptoms such as fatigue, difficulty with decision-making, and a sense of hopelessness. Other features include changes in sleeping patterns, restlessness, irritability, overeating or eating less, digestive issues, and persistent anxiety. A sense of feeling numb, sadness, memory problems, and suicidal thoughts are also common.
Coronavirus has forced all of us to adapt to a very different reality. We are finding out new information on a regular basis. This virus can impact lives not only during the illness but long after recovery. Knowledge is power and crucial to coming through this as intact as possible. Please wear a mask and contact your healthcare provider if you suspect that you may have the virus.
A new study found that COVID can impact the brain more than original thought and age the gray matter by approximately 10 years. The virus seemed to significantly affect brain volume. What was even more peculiar about these findings is that it appeared that those who experienced mild symptoms, or no symptoms, appeared more likely to experience this side effect.
COVID can cause a range of different symptoms with wide fluctuations in terms of intensity and the length of time that symptoms persist. 86% of people exposed to COVID have experienced a loss of smell. While a smaller percentage of people go on to experience ongoing fatigue, brain fog, and impaired cognitive functioning. The lingering symptoms can last a few months to over a year.
More research is needed to understand the long-term effects of COVID in general, and more specifically on the brain.
