What Causes Meniere s Disease?
Meniere's Disease is a disorder that basically affects the sense of balance and hearing of the patient. This condition takes place in the inner ear and it may cause problems like vertigo, where patients experience a spinning sensation and a ringing sound as well. This is a chronic disorder, which requires a number of lifestyle changes so that it can be managed and treated without becoming a debilitating problem.

Read on to know more about the symptoms and causes of the condition.

Symptoms: The various signs and symptoms of this disease include a feeling of fullness in the ear, which has been affected by the condition. Also, most patients have a spinning sensation and a ringing sound in the affected ear. Nausea and vomiting may also be caused by this condition, along with sweating and loss of balance. It is also normal to feel uncoordinated when you are suffering from this condition.

Secondary Symptoms: This condition may also cause many other complications, which are known as secondary symptoms. These include anxiety, depression and stress. This usually happens due to the problems in the ear and even the problem of vertigo. This may cause problems for people who climb heights or ladders for their work or even for other recreational causes. The constant sense of dizziness and spinning may cause a person to become anxious and undertake stress when it comes to carrying out various kinds of functions in day to day living.

Causes:  There are various causes of this condition, even though many medical reports suggest that the exact cause has not really been understood so far. As any doctor will tell you, the in the inner ear there is a labyrinth which contains fluids. When there is a problem with the composition and level of these fluids, the patient may develop Meniere s Disease. This condition specifically affects the inner part of the ear. This part is made up of passages and a cavity as well as soft membrane like structures with hair like sensors. These sensors respond to the fluid s movement within the ear. When this fluid does not have the appropriate levels, it can lead to many complications like Meniere s Disease, which affect the nerve impulse that these sensors catch and transmit to the brain.
Stages: This disease progresses over a set of three stages. In the very first stage, the patient will experience much dizziness and nausea, before that progresses to the second stage. In this stage, the patient will have moderate to severe vertigo. This is also known as the middle stage. Finally, this may culminate into the third or late stage, which leads to more frequent episodes of vertigo. The hearing of the patient and the ringing sound in the ears will also get worse in this stage.

Meniere s Disease -  What are the Reasons Behind It 

Your hearing is one of the most important function your body carries out and sometimes you realize that you are losing your sense of hearing, when it is too late to get it back. There are two main reasons for this. One of the reason is age  and the other is when the inner ear's hair cells break down and do not pick up sound well. Here are 7 ways to safeguard your hearing.

1. Try to avoid loud places
It is not advisable to go to places where you have to shout to be heard, such as in a street, a concert or a construction site.

2. Buy low noise rating equipment
The equipments in your house will make sound that you hear the most. Try to avoid these equipments by buying appliances with a low noise rating.

3. Wear hearing protection at loud places
However, it is true that it is not always possible to avoid loud noises. This is when you need to get hearing protection. Earplugs and earmuffs are two of the best ways to make sure that even when you are in a loud place, your hearing does not get affected. Earplugs and earmuffs generally reduce sound by 15 to 30 decibels, which may be crucial to make sure that later in your life, you do not lose your hearing.

4. Avoid smoke
Smoking raises your chance of hearing loss. Second hand smoke does the same thing. Therefore, try to avoid, both smoking and secondhand smoking. 

5. Remove earwax properly
Earwax cannot be removed properly using a cotton swab. Instead, you should use an irrigation kit. Remember this as otherwise; the earwax could muffle your hearing.

6. Avoid medications which reduce hearing
Certain medications increase hearing loss. Therefore, double check with your doctor to make sure your medicines will not make you lose your hearing.

7. Get your hearing tested
Finally, get your hearing tested as identifying the problem early on can help stop worsen the situation.

7 Tips to Safeguard Your Hearing

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

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!

BAHA Implant
Bone Anchored Hearing Aid (BAHA) is a device surgically implanted to help people suffering from a loss of hearing. Most conventional hearing aids transmit sound through air conduction. The BAHA device is suitable for conductive or mild-moderate mixed hearing loss.

Problems with hearing in the middle or outer ears can be helped with the BAHA device. The sound waves received by the BAHA device bypass the middle ear and get delivered straight to the functioning cochlea in both ears.

A BAHA device comprises of two parts:
a) The processor 
b) A fixture which is surgically implanted behind the ear in the bone.

The implant is embedded in the bone. The processor, which remains outside, is attached to the implant. There is a microphone on the processor that picks up sounds. The sounds are passed on to the implant. The implant vibrates which triggers the Cochlear. You can consider wearing a BAHA implant if other conventional hearing aids do not work for you. BAHA implants are also given to people with collapsed or irritated ear canals.

Cochlear Implant Surgery

A complex, small electronic device that helps hearing in people with severe hearing loss or deafness is used in the Cochlear Implant Surgery. The cochlear implant comprises of an external piece behind the ear and another piece that is surgically implanted under the skin. A cochlear implant comprises of four parts:
1. A microphone which picks up sounds from the surroundings
2. A speech processor which chooses and arranges the sounds the microphone picks up
3. A receiver/stimulator and transmitter that picks up signals from the speech processor and changes them into electric impulses
4. An electrode ray, a bunch of electrodes, receives impulses the stimulator sends and transmits them to different areas of the auditory nerves.
The implant does not cure deafness; it only gives you a useful portrayal of sounds in the environment and considerable aid in understanding speech.

The surgery is done in the following way:
i. The area around the site of the implant is shaved or cleaned
ii. The patient's vital signs are monitored through cables, patches and monitors attached to him or her
iii. General anaesthesia is administered through IV or through a face mask
iv. After the device is implanted, the patient is taken to the recovery room for the anaesthesia effect to lessen.

BAHA Implant and Cochlear Implant Surgery

Did you know your earphones are making you deaf? Here's how.

Fact: Roughly 1.1 billion people worldwide within the age group of 12-35 have been found to be at an increased risk of developing hearing problems.

Listening to loud music on handheld devices using earphones has become a common trend among youngsters these days. You might find it very relaxing to plug in your earphones and escape into your own world of music, but you need to know that this can cause serious damage to your ears. The worst part: you won't realise your ears are being damaged until it's too late.

So, exactly how is loud music damaging your ears?

Continuous exposure to loud music from earphones or other sources results in a medical condition known as Noise-Induced Hearing Loss (NIHL), which can be associated with irreversible damage to the ears resulting in deafness.

When you hear loud music for a considerable amount of time every day it affects your hair cells (nerve cells responsible for sending sound signals to the brain) negatively, so that their ability to respond to sound decreases. If this keeps on happening for many months, eventually the hair cells are damaged beyond repair. These cells cannot be regenerated, making you permanently deaf.

How loud is too loud?

If your ears are exposed to sounds at 95, 100, 105, 110 and 115 dB (decibel, the unit used for measuring sound) for 4 hours, 2 hours, 1 hour, 30 minutes and 15 minutes each day respectively, your ears are at risk of getting severely damaged. Also, playing music at 120 dB or above can damage your ears instantly. You can have a realistic idea about the relation between decibels and sounds you commonly hear by referring to this list:

30 dB: soft whisper
75 dB: busy traffic
90 dB: noise of a motorcycle at 25 feet
100 dB: noise of a farm tractor
140 dB: jet plane taking off
Moreover, if you experience the following symptoms regularly, there's a high chance that you need to get your ears treated soon:

A ringing sound in your ears when you are at a quiet place, which vanishes after a few minutes
You need to raise the volume of TV or music to the fullest to hear it properly
You have difficulty in hearing people talking at a distance of just 3 feet
Tips For Safer Listening

Use earplugs: The louder the noise and the longer you're exposed to it, the greater the chance of damaging your hearing. Protect your ears with ear protectors   earplugs or earmuffs   and get away from the noise as quickly or as often as you can. 
Turn down the music: Don't listen to your personal music player at very high volumes and never to drown out background noise. If the music is uncomfortable for you to listen to, or you can t hear external sounds when you ve got your headphones on, then it's too loud. It's also too loud if the person next to you can hear the music from your headphones.
Use the 60:60 rule: To enjoy music from your MP3 player safely, listen to your music at 60% of the maximum volume for no more than 60 minutes a day. 
Wear headphones: When listening to your personal music player, choose noise-cancelling headphones, or go retro with older muff-type headphones. Ear-bud style headphones and in-the-ear headphones are less effective at drowning out background noise. 
Turn down the dial: Turn down the volume on your TV, radio or hi-fi a notch. Even a small reduction in volume can make a big difference to the risk of damage to your hearing. 
Use earplugs when you re listening to live music: They can reduce average sound levels by between 15 and 35 decibels. They re widely available at many live music venues and shouldn t spoil your enjoyment of the music.
Don't put up with work noise: If you re experiencing noise at work, talk to your human resources (HR) department or your manager and ask for advice on reducing the noise and getting hearing protection.
Wear ear protectors: Wear ear protectors (earplugs or earmuffs) if you are using noisy equipment such as power drills, saws, sanders or lawn mowers.
Be careful in the car: Listening to music in a confined space increases the risk of hearing damage. Don t listen to music too loud for too long.
Have a hearing detox: Give your ears time to recover after they ve been exposed to loud noise. According to Action on Hearing Loss, you need at least 16 hours of rest for your ears to recover after spending around two hours in 100dB sound, for example in a club. Reducing this recovery time increases the risk of permanent deafness.
