Recent studies suggest that tinnitus — a ringing or similar sensation in the ears — is caused by a rewiring of nerves in the auditory cortex (see drawing). These nerves no longer respond to intended frequencies but do become sensitive to neighboring frequencies, which leads to tinnitus.
There’s some supporting evidence in animals, but what about in humans? (more…)
Yes, but not in the way you might think. (more…)
Meniere’s disease is characterized by deafness, ringing in the ears, dizziness, and nausea. Because the precise cause is unknown, most treatments are limited to treating symptoms.
Here’s a summary of CAM options from a review in The Internet Journal of Otorhinolaryngology.
In April 2006 Schwabe Pharma (Australia) launched a marketing campaign promoting Tebonin for “tinnitus and vertigo relief.” Tebonin is an extract of Ginkgo biloba leaves called EGB761.
Now, the British Medical Journal reports that a federal court in Australia has granted an injunction sought by the company to temporarily suppress a report by a consumer watchdog group called AusPharm Consumer Health Watch that is critical of this product.
The advertisement for Tebonin states that it has shown “through clinical research to be an effective treatment for a range of conditions relating to microcirculation including tinnitus, vertigo, peripheral circulation and cognitive function.”
It continues, “Tebonin optimizes the flow properties of the blood through capillaries increasing the amount of oxygen supplied to all organs, tissues and individual cells throughout the human body, effectively reducing the amount of free radicals within cells and enabling optimum cell function.”
A detailed review published in The Journal of the American Botanical Association makes no mention of EGB research on tinnitus or vertigo.
