A cochlear implant is an electronic device that is used to restore hearing ability in people who suffer from hearing loss due to inner ear damage. Unlike hearing aids which amplify sounds so people with hearing loss are better able to perceive them, cochlear implants directly transmit electronic sound signals to the auditory nerve. They work by compensating for damaged cochlea, the part of inner ear that converts sound waves into neural impulses which are perceived by the brain. 

A child who cannot hear will also never be able to speak. 
Inability to hear and speak puts a person at disadvantage in society. 
Simple tasks like talking on the phone which we take for granted become impossible. 
Conventional methods of learning like attending a classroom lecture become impossible. 
Brain development and intelligence is closely linked to development of speech and language. 
Inability of parents to communicate with child leads to emotional distancing. 
Integrating a hearing disabled person in to society becomes a frustrating experience for all involved. 
Cost of integration per capita in much higher when compared to cost of Cochlear Implant. 
Children with Cochlear Implants are fully integrated in society with normal hearing & speech. 
Children with Cochlear Implants can attend regular schools & colleges 
Early identification of hearing impairment gives children a better chance of developing speech and language skills, and of making the most of social and emotional interaction from an early age. 
Cochlear implants offer a multitude of benefits to people experiencing hearing loss, especially infants and children with severe hearing loss who are just starting to process language and speech. Some of these benefits are: 

Hearing and communication   Cochlear implants improve hearing significantly, especially to a level where normal communication can be restored. It enhances the person s ability to hear speech without relying on visual cues such as lip reading or hand signs. It makes telephonic conversation a lot easier. Cochlear implants also help people regulate their own voice and volume so that it is easier for others to understand them. 
Quality of life - It can help people with hearing loss listen to and enjoy music and also watch television with sounds. It helps people listen to sounds in a noisy environment and differentiate soft sounds from loud ones. 
Safety   Cochlear implants enhance the individual s safety as it allows the person to be able to hear warning sounds like honking cars or ambulance sirens. This will allow people to navigate public spaces in a much safer way. 
Society - For children with hearing loss, cochlear implants can help them adjust a lot better to regular schools instead of requiring special institutions. 
Brain development - It can help infants with cochlear damage develop their speech recognition and speaking skills much faster. 
Cochlear implants 

Only device of its kind that can restore a special sense.
Consists of 2 parts-
One part is surgically implanted in the body 
Second part is worn behind the ear and communicates with internal part using wireless signals 
Persons of any age can get a cochlear implant, from less than one year old children to 90 year old persons have received implants all around the world. 
Cochlear implants can be done for partial hearing loss also, know as Hybrid implant that preserves the residual natural hearing and augments hearing only in certain sound frequencies in which hearing loss is present. 
Are being used for indications other than hearing loss also like Tinnitus. 
Surgery is a day care procedure for most patients.

Cochlear Implant - The Many Benefits Of It

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.

Sleep apnea is a disorder which is characterized as interruptions in breathing when you are sleeping. These interruptions or pauses in breathing usually last for about 10 to 20 seconds and may be repeated over 100 times alongside the duration of your sleep. This condition leads to poor sleep resulting in drowsiness, fatigue and poor concentration throughout the day.

Sleep apnea can be classified as:
1. Central sleep apnea: Central sleep apnea impairs the central nervous system wherein the brain fails to control muscles which regulate breathing while you sleep.
2. Obstructive sleep apnea: This type of sleep apnea occurs when the soft tissues present in the back of the throat block the airway and thus resulting in loud snoring.

Signs and symptoms
The various signs and symptoms of sleep apnea are
1. Loud and chronic snoring during sleeping
2. Interruptions in breathing
3. Shortness of breath during sleep
4. Fatigue during the day
5. Choking and gasping during sleep
6. Extreme irritability and drowsiness
7. Experiencing headaches in the morning
8. impaired concentration and forgetfulness
9. Chronic sore throat and dry mouth
10. Depression

The various risk factors for sleep apnea are:
1. If you are overweight
2. If you are male
3. If you are over the age of 40
4. If you have a large tongue and tonsils
5. If someone in your family has sleep apnea
6. Nasal obstruction due to sinus problems

There are certain prevention measures to control sleep apnea, they are:
1. Limit smoking: Smoking may cause you to retain fluid in the throat which contributes to sleep apnea.
2. Exercise: You should exercise regularly to keep off weight as being overweight increases the chances of getting affected by sleep apnea.
3. Schedule your sleep: You should get enough sleep every day so that your body is refreshed and revitalized. Getting enough sleep, thus helps in preventing sleep apnea.

Risk Factors Associated with Sleep Apnea

Pain related sleep disruption has affected a large number of people around the globe. Statistics has it that, in India, about 25% of the population suffers from pain-related sleep deprivation. Studies call it  the vicious cycle of pain and sleep  as pain affects your ability to sleep and lack of sleep makes the pain even worse.

Back pain and arthritis are examples of some common pain-related medical disorders. People with these types of chronic pains have reported persistent sleeplessness or have had immense trouble falling asleep.

The following are the primary sleep disorders associated with chronic pain:

Insomnia: It is a medical condition that is characterized by an inability to fall asleep no matter how physically exhausted you are. Insomnia can be acute (lasting for one night to a week) or chronic (that lasts for more than 3 weeks).
Hypersomnia: It is a condition wherein you tend to sleep excessively; in this condition, you will have trouble being awake throughout the day or can fall asleep at any point of time.
Sleep Apnoea: This is a sleep disorder wherein breathing pauses and resumes repeatedly. Risk factors include obesity, age and gender; it is more commonly observed in men. This condition can be chronic with symptoms such as snoring loudly or feeling very tired even after one has had a night s sleep.
Restless leg syndrome: It is a sleep disorder wherein you continuously move your legs while sleeping. However, this condition can also cause you to move your legs even if you aren t sleeping.
Some of the causes of sleep disorders due to chronic pain are:

Pain
Worry and anxiety
Sweating at night
Depression and other mental disorders
Treatment

A pain and sleep disorder should be simultaneous as both the components of it, pain and sleep, are interrelated. Some of the ways people with chronic pain can still have a good night s sleep are:

Limiting caffeine intake
Abstaining from alcohol and smoking, as these disrupt the sleep cycles, thus aggravating the existing pain.
Practicing meditation and other relaxation techniques
Pain killers or sleeping pills can be administered, but only with the doctor s advice.
Hot water fomentation over painful area during night, for better sleep.

Back Pain and Bad Sleep

Migraine is a very common form of a headache which strikes nearly 15 % of the population. Females are more prone to migraines. Science has not been able to find the real cause behind migraine attacks and the way it treats these massive headaches is also patchy at best. A migraine occurs for a definite period of time, usually, comes with a warning and paralysing pain.

Ayurvedic view
According to Ayurveda, migraine is a tri-dosha disorder. It occurs when vata or the wind element goes out of sync. Vata controls the nervous system and brain activity. Vata imbalances are linked to many diseases like joint problems, dizziness and it happens because of faulty metabolism, poor elimination, sleeplessness, etc. Pitta the fire element also has a role to play in migraines. It causes dilation of the blood vessels, which brings on a migraine attack.

Ayurvedic physicians can identify which dosha is causing a migraine. If the patient is constipated, has acute pain and has dry skin, his Vata is out of whack. If a patient has nosebleeds, is hypersensitive to light, has burning eyes and is irritable, pitta is out of balance. And if a patient has fatigue, is depressed and has a dull throbbing in the head, he is suffering a Kapha imbalance.

Ayurvedic therapies

Shirolepa: Application of herbal pastes to pacify pitta like sandalwood, camphor, Jatamansi.
Shiro Dhara: Medicated oils are poured on the scalp.
Taila dhara: Oils like ksheerabala taila, chandanadi taila are poured on scalp for calming higher vata imbalances. 
Ksheera dhara: Here cow milk is poured on the scalp to pacify pitta.
Takra dhara:  Also known as buttermilk is poured when there is obstruction to passage of vata.
Kavala graha: Oil pulling done with oils like chandanadi taila and mahanarayana taila.
Shirovasti: Medicated oils are retained on the scalp by wearing a leather cap.
Sneha nasya: Oils like Anu tailam are poured into nostrils.
Apart from there therapies herbs like Kumari or Aloe vera, Amalaki or amala and Bala or Sida cardifolia are very useful as migraine cures. Several Ayurvedic medicines are also very useful in migraine-like-

Pathyadi khada: It is used in the treatment of headaches, earaches, and migraine etc.
Shirashooladi vajra rasa: It is used in the treatment of headache, migraine, tension headache, vascular headache etc.
Bhoonimbadi khada: Used as a cure for fever, cold, sinusitis, headache.
Kamadugha rasa: Used to cure all high pitta conditions.
Godanti Bhasma: 250 mg of this medicine is also given twice a day for immediate relief from migraines.
Patients should also eat warm, nutritive foods like sesame, sweet fruits, cumin, garlic, jaggery and rice for balancing Vata. For balancing pitta, they should stay away from smoking and drinking at the very least.

Migraine - 8 Ayurvedic Remedies For Treating It!

Obesity is the new-age lifestyle disease with multiple ramifications. While its effects on the physical aspects are very evident, the damage it does to the brain are more severe, though not obvious. Read on to know some harmful effects of obesity on the emotional well-being.

Leads to binge eating: There is a certain pleasure in eating sugary and fatty food, and this is lost with depression. Therefore, to get that emotional satisfaction, people tend to eat more chocolates, cookies, milkshakes, and other weight-accumulating food items, which further add to obesity. Greater the weight gained by a person, lesser the response or happiness from such food products.
Increases impulsivity: The area of the brain known as orbitofrontal cortex, which is in charge of controlling impulsivity, shrinks in obese people. This results in people eating more impulsively.
Affects immunity: Obesity is a major cause of inflammation, leading to damage in certain parts of the brain. This impairs the immune system, making the affected person more prone to infections and tissue damage. This leads to increased chances of diabetes, heart disease, stroke, sleeping disorders, eating disorders, etc. The chemical known as C-reactive protein increases as seen on MRIs in obese people, and which is usually seen in patients with chronically increased inflammation.
Effects on memory: As the BMI increases, there is a decrease in scores of memory tests. This effect is more obvious in women after menopause. With increased fat accumulation, more hormones are released, which affects the memory. Increased inflammation also affects cognition and memory.
Increased risk of dementia: With more belly fat accumulating, there is extra stress on the body to burn the visceral fat. This reduces brain size and causes certain hormones to release, which further affects the body s ability to remember things. It has been proven that people with smaller brain size are at greater risk for developing dementia.
Weight loss stress adding to more stress: When obesity sets in and the BMI goes up, there is an added pressure to lose weight, which further ups the stress levels. During these dieting days, the brain is constantly alert and finds ways to eat more. This also leads to excess eating. Moreover, there are indications that there could be genetic changes during this phase, which may leave a permanent mark in the person s composition.
Depression: When a person is not happy with their reflection in the mirror, the chances of feeling good and happy are very less. In this age, where aesthetics plays a major morale booster, an obese image staring back does not help at all.
So, if you have a risk of obesity, watch out. It is not just how you look, but how you feel is also altered.
