One of the most often searched for topics on my blog is the one about Tinnitus--The Roaring in my Head. Since so many searches are leading to that topic on this blog, I am guessing that quite a few people are affected by tinnitus.
In Healthy Hearing, a recent article, "Brain Imaging May Hold Clues to Ringing in the Ears," focused on tinnitus. The article stated that scientists are exploring the causes of tinnitus in the brain. Research currently shows that people with tinnitus seem to have a lower amount of gamma aminobutric acid (GABA) than people without tinnitus.
Imagine popping a GABA pill before heading to bed to make the roaring go away!
