A one-time exposure to extreme loud sound or listening to loud sounds for a long time can cause hearing loss. Loud noise can damage cells and membranes in the cochlea. Listening to loud noise for a long time can overwork
Aging and loud noise can cause wear and tear on the hairs or nerve cells in the cochlea that send sound signals to the brain. Damaged or missing hairs or nerve cells don't send electrical signals well. This causes hearing loss. Higher pitched tones may seem muffled.
When the auditory nerve is damaged, the primary symptoms are sensorineural deafness and/or vertigo. The auditory nerve is the 8th cranial nerve. It connects the inner ear to the brain. The auditory nerve divides into two branches: the cochlear nerve and the vestibular nerve.
Unfortunately, the cells in your ears are fragile and rely heavily on a steady blood stream to receive oxygen and nutrients. Without this steady blood flow, the cells become damaged, affecting your ability to hear. Chronic stress can lead to gradual hearing loss, sudden hearing loss, and even tinnitus.
Recovery times vary greatly depending on the severity of your condition and where on your vestibular nerve the damage occurred. Some people may recover in just one week. Others may have lingering symptoms that last weeks, months or even years.
An MRI scan may reveal a growth on the nerve pathway that connects the ear to the brain, such as an acoustic neuroma. These growths can prevent the ear from functioning well and may cause hearing loss.
An ABR test uses electrodes placed on a person's head and ears to monitor brain wave activity in response to sound. An OAE test uses a small, very sensitive microphone inserted into the ear canal to monitor the faint sounds produced by the outer hair cells in response to auditory stimulation.
Acoustic neuroma can be treated effectively if diagnosed early. But if left untreated, it can lead to serious neurological problems. The life expectancy for patients suffering from an acoustic neuroma is very favorable with most patients enjoying productive lives.
Vestibulo-Cochlear Nerve Damage & Central Auditory System Changes. The vestibulo-cochlear nerve, or eighth cranial nerve, carries signals from the inner ear to the brain. Tinnitus can result from damage to this nerve.
Vestibular neuritis is a condition that affects the vestibular nerve, which connects the inner ear to the brain, causing prolonged vertigo usually in the absence of significant hearing loss.
Coming from the inner ear and running to the brain is the eighth cranial nerve, the auditory nerve. This nerve carries both balance and hearing information to the brain.
Tinnitus is one of the most elusive conditions that health care professionals face. It is an auditory perception not directly produced externally. It is commonly described as a hissing, roaring, ringing or whooshing sound in one or both ears, called tinnitus aurium, or in the head, called tinnitus cranii.
Anything you eat, drink, or do, that upsets the fluid level in the body can upset the fluid level in the ear and cause tinnitus. Keeping a moderate intake of caffeine, salt, and alcohol. Reducing your use of tobacco. And staying hydrated by drinking water will help reduce the impact of tinnitus.
If tinnitus is unilateral—meaning you hear the noise in only one ear—doctors may recommend an imaging test. Unilateral tinnitus may indicate a structural problem or medical condition on one side of the head that can be viewed using imaging techniques.
Doctors suggest that fluttering in the ear is a type of tinnitus called MEM, which is caused by jerky movements of the muscles in the middle ear. Doctors need to individualize treatments and follow up with people who experience fluttering in the ear, since responses to treatments vary greatly from person to person.
A head MRI scan can diagnose issues having to do with the brain, nerves of the brain, inflammation in the head, inner ear problems, and the spinal cord.
Some nerve-related problems do not interfere with daily life. Others get worse quickly and may lead to long-term, severe symptoms and problems. When a medical condition can be found and treated, your outlook may be excellent. But sometimes, nerve damage can be permanent, even if the cause is treated.
In many cases, supplementing with vitamin B-12 can reduce the pain associated with neuropathy. More rarely, it can help repair the myelin sheath, depending on the cause of the neuropathy. However, B-12's ability to speed up tissue regeneration and improve nerve function can be helpful for some.
Tinnitus - a ringing in the ears - is a condition that is associated with anxiety and research suggests that around 45% of people who have tinnitus also have anxiety symptoms.
