Tinnitus, the buzzing, humming or ringing sounds perceived in the ears or head – can be as quiet as a whisper one minute or as loud as a jackhammer the next. Tinnitus afflicts about 50 million people in the United States and is the leading form of disability affecting women and men in uniform — more than 12 percent of American troops returning home have been exposed to acoustic trauma from machinery or blast-induced tinnitus from explosive devices. Patients with tinnitus have been shown to process emotions differently in the brain from people with normal hearing, and studies show that tinnitus is often linked with increased stress, anxiety, irritability and depression. When the ears are exposed to loud noise or infections, the tiny hair cells that transmit sounds to the brain (stained red in image above) become stressed and start to emit excess quantities of glutamate, a type of chemical messenger known as a neurotransmitter. Called a ‘glutamate storm,’ this over-stimulates nerve cells in the inner ear to the point where they eventually die.
These nerve cells have the job of sending sound impulses up to the auditory cortex, the part of the brain that processes noise. By this point, the tinnitus is no longer being caused by the damaged ear cells but is rooted in the brain itself.
Medical disorders such as hypo- or hyperthyroidism, Lyme disease, fibromyalgia and thoracic outlet syndrome.

In a small study published in the journal Otology and Neurotology researchers at Antwerp University Hospital, Belgium, treated 248 patients with either the real gel or a placebo.
So far the AM-101 treatment is only suitable for people who have had tinnitus for less than a year and in cases where the onset can be attributed to a specific cause, such as a loud blast of sound or an ear infection. Researchers are also working with a non-invasive imaging technique called magnetoencephalography (MEG) to help pinpoint the sites in the brain where tinnitus is perceived.

For some people these phantom sounds can range from whooshing noises to train whistles, cricket noises or whines. When the nerve cells in the inner ear die, it leaves nerve cells in the auditory cortex in a permanently switched-on state, where they constantly relay sound to the brain, even when there is no incoming signal from the ear. Scientists have combined vagus nerve stimulation with playing audible tones to decrease the symptoms of tinnitus. Forty-two per cent of patients in the treatment group reported that their tinnitus symptoms were reduced by half, compared with only 14 per cent in the placebo group.

The hope is that MEG will allow physicians to target these area with electrical or chemical therapies to lessen symptoms.

After 90 days, 57??per cent of those taking the active gel said their tinnitus was ‘much improved’ or ‘very much improved’. Researchers hope that blocking the receptor will prevent glutamate from binding to the nerve cell and causing damage, giving the damaged nerve cells a chance to regrow before tinnitus can set in for good.
