What causes hearing loss? + How to ensure you can help it as you age

The partial or total inability to hear is known as hearing impairment or hearing loss. It can be present at birth, or develop later in life.

There are a number of factors, which may cause hearing loss

1. Age - Age is the biggest factor when it comes to the loss of hearing, and you may lose the ability to hear as you age. This condition is known as presbycusis. It becomes difficult to understand high-frequency sounds like that of a child or a woman when you get old.

2. Noise - When you are exposed to loud noises for a prolonged period of time, it damages your ears. This leads to loss of hearing. 5% of the total population of the world is affected by noise (the degree of suffering varies). It may be a result of continuous exposure to loud music or a sudden exposure to a loud noise like an explosion.

3. Hereditary disorders - Hearing disorder may be inherited by the dominant or recessive genes of parents in the child. 70-80% of these cases inherit from the recessive genes, whereas 20-25% inherit hearing loss from the dominant genes.

4. Trauma - Serious injuries of the head/ears may cause loss of hearing, which may be either temporary or permanent. When damage is caused to the brain, the brain fails to process the message conveyed by the ears. So even if the ears are totally functional, a person may face the problem in hearing.

5. Perinatal problems - The ototoxic effects on the fetus due to excess intake of alcohol during pregnancy lead to hearing the loss in about 64% of the infants born to alcoholic mothers.

Also, premature birth can be associated with hearing loss due to high risk of being exposed to noise in neonatal units.

Knowing about the causes of hearing loss can lead you a step closer to preventing this disorder as you age.

Here are some useful tips that can help prevent hearing loss:

1. Be more aware - You should be diligent and aware of the situations, which may risk your hearing ability and should try to avoid such situations as much as possible. Limit your exposure to sources of hazardous noises like firearms, firecrackers, concerts and clubs.

2. Take precautionary measures - If your occupation calls for working at an environment of loud noises, use earplugs or earmuffs to block out the excessive noise. Also, make sure that you work in a place where employers take all the necessary measures of noise control under the federal or state regulations.

3. Monitor your use of gadgets - Monitor and control the use of hearing devices, and try to reduce the use of headphones/ earphones as much as possible.



What causes hearing loss? + How to ensure you can help it as you age

Hearing loss is a common sensory problem that generally develops with increasing age or due to prolonged or persistent exposure to loud noises. It is one of the most typical problems that occurs throughout the world. If you are suffering from partial hearing loss, you may find ways of keeping in touch with your family and friends. If you are not suffering from such the following may help you keep your hearing intact for years to come.

Types of hearing loss
There are two main types of hearing loss: 
1. Conductive hearing loss where the problem lies in the middle ear, eardrum or ossicles. A conductive hearing loss affects the passage of sound between the eardrum and the inner ear. Sound passes down the ear canal to the ear drum and through the middle ear, where the sound is transmitted across the middle ear by the three bones called the ossicles to the inner ear.

Causes of conductive hearing loss:
1. Malformation of outer ear, ear canal, or middle ear structures
2. Fluid in the middle ear from colds
3. Ear infection (otitis media - an infection of the middle ear in which an accumulation of fluid may interfere with the movement of the eardrum and ossicles
4. Allergies
5. Poor eustachian tube function
6. Perforated eardrum
7. Benign tumors
8. Impacted earwax
9. Infection in the ear canal
10. Foreign body in the ear
11. Otosclerosis

2. Sensorineural hearing loss where there is damage in the inner ear, cochlea or hearing nerve. Sensorineural hearing loss (snhl) occurs when there is damage to the inner ear (cochlea), or to the nerve pathways from the inner ear to the brain. Most of the time, snhl cannot be medically or surgically corrected. This is the most common type of permanent hearing loss.

Causes of sensorineural hearing loss:
1. Exposure to loud noise
2. Head trauma
3. Virus or disease
4. Autoimmune inner ear disease
5. Hearing loss that runs in the family
6. Aging (presbycusis)
7. Malformation of the inner ear
8. Meniere's disease
9. Otosclerosis 
10. Tumors

Coping with hearing loss
Antibiotics and eardrops are often prescribed to treat hearing loss and its symptoms. In many cases, people suffering from severe hearing loss use hearing aids. Hearing aids are tiny instruments that people use in their ears to make sounds louder. People who suffer from hearing loss cope with their problems through increased concentration and focus. The usual way involves reading the moving lips of the person while they talk. Prevention is better than cure and is the best solution to avoid long term hearing loss. Avoiding continuous loud noises, to the possible extent helps prevent hearing loss to a great extent.

All About Hearing Loss

Usher syndrome is a genetic disorder that is characterized by complications in vision and hearing; the most common of them being partial/complete loss of hearing and retinitis pigmentosa. Retinitis pigmentosa is characterized by progressive deterioration of the retina, resulting in deprivation of peripheral vision and subsequent night blindness.

The symptoms and its rate of progression usually vary among people. Usher syndrome is classified into three types:

Type 1: In this type, children are born with balance issues and hearing loss problems. The symptoms of night blindness and loss of peripheral vision associated with  Retinitis Pigmentosa  only appear in the early stages of adolescence.
Type 2: In type 2, children are born with moderate to mild hearing loss problems. Retinitis Pigmentosa develops soon after the child reaches adolescence.
Type 3: In type 3 Usher Syndrome, children are usually born with normal hearing skills, however, loss of hearing and Retinitis pigmentosa occur soon after puberty.
Causes
Hearing loss in Usher syndrome occurs when the nerve cells that are present in the cochlear (inner ear s spiral cavity) are affected by genetic mutation. A similar problem occurs in the cells of the retina leading to loss of vision. These cells allow conversion of light into electrical signals for the brain to interpret them. Both the parents need to pass the mutated gene to the child for it to be affected. If the child has only one gene, then he/she rarely develops the symptoms.

Treatment
This disorder does not have any prescribed course of treatments. The vision loss that occurs in this disorder can be slowed down by nutritional therapy. This therapy involves providing the body with essential amounts of vitamin A which can help in reducing vision loss.

Usher Syndrome - Things You Must Know!

Hearing loss is experienced by millions of people these days. Ageing is not the only factor that brings hearing impairment. The causes are many. Certain medications, continuous exposure to loud noise, genetic involvement, injury and some medical conditions may cause hearing loss.

There are quite a few myths that people have come to believe about hearing loss over the years. Since it is such a common phenomenon, here we take a look at the common myths surrounding hearing loss.

Myth no. 1: Hearing loss is exclusive to elderly.

Fact: As said before, hearing loss can be an outcome of various causes. Nearly half of the people suffering from the same are below the age of 55 years. No matter what your age is, you must always get your ears checked, especially if you are feeling that are you missing things.

Myth no. 2: Diagnosing hearing loss is easy.

Fact: Most people do not come to know about the condition until it gets worse. Also, your physician never really checks for hearing loss symptoms in a general check-up unless you ask for it specifically.

So, always get a check-up done, like you do for other probable diseases.

Myth no. 3: There's no effective solution for hearing loss.

Fact: Like there have been advancements in the medical field for everything else, there are aids available these days that improve your hearing and have finer adjustments for noise adaptation. Also, there are certain other procedures and surgeries that have proved to improve the condition in many.

So, seek help as soon as possible.

Myth no. 4: The sounds aren't loud enough; my ears are healthy and fine.

Fact: If there is a problem you're experiencing with hearing, you have got to accept that and get it treated. Avoiding a certain condition will only get things worse for you.

Also, hearing aids are no more a stigma. Ear aid devices have designs similar to earphones these days, which are comfortable enough to wear. Ignoring a medical condition or inability to accept the same would only do more harm instead of making things fine.


Common Myths About Hearing Loss

Cochlear Implant is an electronic device replaced with the inner ear (cochlea) of the patients who are unable to send sound waves to the brain.

The surgery is performed on the patients who have the problem of hearing loss due to the damaged hair cells in the inner ears. The implant helps the patient to hear which are not responding to other hearing aids.

Conditions for Cochlear Implant:

Cochlear implants help people to hear with clarity. They are not like hearing aids, which make the sound louder, but it helps send sound waves to the brain and replaces the damaged hair cells in the inner ear. Following are cases where it is beneficial:

People who find it difficult to hear clearly with hearing aids.

Those with moderate hearing loss in both ears.

Patients with 50% or fewer score in the sentence recognition test.

Patients with 60% or less score in sentence recognition test with hearing aids on.

It is suggested to opt for cochlear implants in both ears. The reason is to give the patient a better perspective of sound direction and clarity in understanding the words.

How does the Cochlear Implant work?

Cochlear Implant is an electronic device with an embedded sound processor that has to be worn outside ears or on the body. Following steps are involved in cochlear implant:

The sound captured by the processor is converted digitally by the processor and sent to the coil inside the ears of the patient.

The implant converts digitally coded sound waves to electrical impulses.

The electric impulse simulates the hearing nerve of the patient.

Then sends these impulses to the brain.

Benefits of Cochlear Implants:

The cochlear implant is a blessing for people who have been suffering from hearing loss for a very long time. It provides aid to people who have not benefited from hearing devices. The benefits of the cochlear implant are:

Hear better.

Studies have shown that people with cochlear implants have better sentence recognition scores instead of hearing aids.

The patient can concentrate better in the crowd and can hear conversations across the table.

Reconnect with the missed sounds.

Enjoy music on the phone.

Cochlear Implant improves the quality of life of people with hearing loss. It gives them an aid to understand and engage themselves in a conversation. However, it takes time to learn the interpretation of the sound signals that are received from cochlear implants. But, the patient can learn and lead a normal life with the implant. The factors which affect the benefits of Cochlear implants are:

The extent of hearing loss

The duration of the hearing loss and the condition before implantation

Damage to inner hair cells

Other health issues

The practice and rehabilitation time have been done in practice after implantation

The cochlear implant is performed in the patients after taking extensive tests determining the condition of the patients. It is activated after 2-6 weeks of surgery to give the surgery site a time to heal. Most people are discharged from the hospital after surgery and are prepared for the use of an implant. There are training sessions and classes for patients who have just gone for cochlear implants.

Cochlear Implant - How Do They Help?

Hearing loss is not something limited to elderly men or elderly women only. This is something that can affect any adult at any stage of life. The good news is that it can be managed. Today, there are a number of hearing aids that can help improve hearing ability. These aids allow an individual who has lost part of his or her hearing to live a normal life. For best results, hearing loss should be arrested in its early stages.

Here are a few signs you should look out for.

Muffled Speech: When you hear people talk, their speech should be clearly identifiable. If you hear muffled noises that you have to interpret as words, it could be a sign of hearing loss.
Difficulty understanding words: The human ear has the ability to separate conversational sounds from ambient noise. However, in some cases where the inner ear is damaged, a person might find it difficult to separate the two. In such cases, the person might not be able to understand words clearly as they get confused with background noise. This is a sign that must never be taken lightly.
Feeling the need to ask people to repeat themselves: Once in a while if you find yourself asking another person to repeat what he or she said, there is nothing to worry. However, if this becomes a regular occurrence and happens with many people, then the fault lies in your hearing. Thus, if you notice yourself needing to ask people to repeat themselves or talk slowly, consult a hearing specialist.
Increasing the volume of the radio or television: As children, we are taught that playing music or watching TV at a very high volume can damage the ears. The radio, television and other such appliances should be played at a volume where the information being relayed is clearly audible and people can have a conversation alongside without needing to shout. If you find yourself having to increase the volume constantly, it could be a sign of hearing loss.
Withdrawing from conversations: As hearing loss is aggravated, people begin to feel conscious of having to ask others around them to repeat themselves or talk slowly. This can make them withdraw from a conversation and other social situations. In many cases, the simple reason for avoiding a party could be the discomfort of not being able to hear the other person clearly in a conversation.
 All hearing problems can be better handled by proper investigation, different test, sign and symptoms of the patient, which are carried by a specialist of hearing, called as AUDIOLOGIST, who can look your hearing problems, plan out treatment plan, rehabilitation pre and post etc. Audiologist will definitely help you hear again.
