Causes of Hearing Loss in Adults
Regardless of whether you’re a parent, an older adult, or someone just starting to notice that they have lost their hearing, there are ways to deal with it. In this article, we’ll look at the different types of hearing loss and treatments available. We’ll also take a look at some of the common causes of hearing loss.
Hereditary hearing loss
Approximately one in three people older than seventy-five years has some form of hearing loss. There are many factors that contribute to this condition. Generally, genetics plays a major role. However, environmental factors also contribute. A person’s risk of hearing loss is related to smoking, high blood pressure, diabetes, and other disorders. The most common environmental cause is noise exposure.
The inner ear plays a vital role in hearing. Damage can occur to the inner ear nerve pathways or the sensory hair cells. When this happens, the person may have permanent deafness. A doctor may perform tests such as an otologic examination to document the person’s hearing loss.
Genes also play a role in the development of hearing loss. Scientists have identified several genes that are responsible for deafness. Some of these genes only affect males, while others affect both males and females. There are also many different types of deafness. Some are classified as genetic hearing loss, while others are classified as acquired hearing loss.
Genes that cause hearing loss are classified as either autosomal dominant or recessive. Autosomal dominant means that the gene is present in both parents. If one copy of the gene is mutated, the child will have deafness. However, the other copy of the gene will be normal.
Abnormal chromosomes can also cause deafness. Mutations in the “GJB2” gene are one of the most common causes of hearing loss. This gene causes about 50 percent of severe to profound nonsyndromic deafness in many populations.
Other genetic causes of hearing loss include ototoxic drugs, maternal infection with cytomegalovirus, and prematurity. Approximately 40 to 50 percent of congenital hearing loss is caused by nongenetic factors. Some of the nongenetic causes include postnatal infections, maternal infections with cytomegalovirus, prematurity, and prenatal exposure to ototoxic drugs.
If a child has a genetic disorder that causes deafness, he or she will need a comprehensive evaluation. This includes an otologic examination and audiology testing. It will also require ancillary testing, such as genetic testing.
The earliest detection of a child’s hearing loss can lead to early intervention. This may include surgery to implant cochlear implants. It is also important to document the family history of hearing loss. This can be accomplished through medical records and direct examination of relatives.
Age-related hearing loss
Approximately one in five adults between the ages of twelve and sixteen suffer from some form of hearing loss. It is not surprising, then, that one in every three adults over the age of sixty-five is also affected by age-related hearing loss. It is a condition that negatively impacts the health and well-being of older adults.
There are many risk factors for age-related hearing loss. They include dietary factors, noise exposure, and specific genetic risk mutations. There are also a number of advanced therapeutic interventions, such as hearing aids. However, there is little evidence about the effectiveness of these interventions.
The World Health Organization reports that approximately 466 million adults are affected by moderate hearing loss globally in 2020. The majority of these cases are irreversible. However, research has shown that hearing aids improve the overall health of people with hearing loss. In low- and middle-income countries, where healthcare resources are limited, the health benefits of hearing aids may be more pronounced.
In order to determine the effectiveness of hearing aids, researchers analyzed data from a community-based survey. They found that 10 to 20 percent of hearing-impaired older adults used hearing aids. However, the cost of hearing aids can inhibit their use of them. The study also found that hearing aids could improve other health outcomes in rural China. The study suggests that hearing aids are the most effective treatment for age-related hearing loss.
In addition to hearing aids, aural rehabilitation is the most effective treatment for age-related hearing Loss. This type of intervention is also the most cost-effective. The study found that aural rehabilitation improves both functional and mental well-being for people with hearing loss.
The study suggests that there is potential for widespread testing of a novel intervention for adults with hearing loss. It also describes a community engagement approach to addressing hearing care disparities.
Another study from the Institut Pasteur suggests that a gene therapy that targets GJB2 mutations has the potential to treat three different pathologies. These mutations alter the gap junction protein, disrupting the exchange of molecules between cells. This technology has the potential to target age-related hearing loss in adults and pediatric congenital deafness.
Noise-related hearing loss
Approximately 17.3 percent of adults and teens are affected by noise-related hearing loss, according to the Centers for Disease Control and Prevention. The majority of noise-related hearing loss occurs during occupational exposures. However, recreational noise can also contribute to hearing loss.
Noise-induced hearing loss can cause tinnitus, which is a ringing, buzzing, or roaring sound in the ear. Tinnitus can affect one or both ears and can continue throughout your life. It can also lead to communication and relationship problems and depression.
Noise-induced hearing loss can be prevented and treated. In fact, you may be able to reverse the effects of noise-related hearing loss if you follow certain guidelines. These include avoiding exposure to loud noises, using protective devices, and wearing hearing aids.
Occupational NIHL can be dangerous and can lead to permanent damage to your hearing. Studies show that it can have a significant impact on your quality of life. A 2013 Global Burden of Disease Study estimated that noise-exposed U.S. workers suffered from a life-limiting condition that resulted in fewer healthy years to enjoy life.
In addition, NIHL has also been associated with other factors. Some of these include gender, age, and race/ethnicity. In addition, certain occupational and recreational noises are known to be unsafe.
Hearing loss is caused by the force of sound waves on delicate structures in the ear. This can occur when you are exposed to loud, continuous noise for an extended period of time. The longer you are exposed to loud noise, the greater the damage.
If you have noticed the hearing loss, contact your doctor right away. If you suspect you have hearing loss, consider taking a hearing test. If you have temporary hearing loss, you may be able to regain your hearing in a short time by moving away from the noise or wearing protective devices.
In addition, the amount of time that you are exposed to noise is a key factor in determining the severity of your hearing loss. Continuous exposure to noise is the most damaging, while intermittent exposure is less damaging.
Treatments for hearing loss caused by ear infections
Several different causes of hearing loss can occur in adults. Ear infections are one of the most common causes. They can cause hearing problems and balance issues. In some cases, they can lead to permanent hearing loss. Ear infections are caused by bacteria and viruses. Some people are more susceptible to ear infections than others. The severity of the infection will determine what treatment you need.
Ear infections can affect anyone at any age. During an infection, there is a buildup of fluid behind the eardrum, which slows down the movement of sound vibrations. These fluids may linger for several weeks or months, causing hearing loss.
Ear infections may be caused by viruses, bacteria, fungi, or a combination of these. In order to diagnose and treat the infection, your healthcare provider will perform a physical exam. He or she will also listen to your breathing. If your ear symptoms do not improve within three days, you will be advised to see an ENT (ear, nose, and throat) doctor. The doctor will prescribe an antibiotic and may recommend a pain reliever.
Children are more likely to develop ear infections than adults. They are more vulnerable to ear infections because they have smaller eustachian tubes, which make it difficult for fluid to drain out of the middle ear. These tubes can be blocked by swelling or enlarged adenoids.
Children with acute otitis media may experience mild hearing loss. They may also exhibit tugging at their ear, which indicates the presence of an infection. The infection may also spread to the mastoid bone, causing vertigo. If a child develops a chronic ear infection, he or she may experience hearing impairment or delayed speech development.
If you have a chronic skin condition, you are more likely to develop ear infections. You can help prevent them by washing your hands frequently, keeping your nasal passages clean, and keeping your ears dry.
Ear infections can occur anywhere in the ear. They are caused by bacteria and viruses and are most common in children. You can use pain relievers and antiviral medications to treat them. You can also have a small tube inserted into the ear canal to help drain the fluids out of the ear. This procedure is called a myringotomy.
