I have several friends my age that also have tinnitus (ringing in the ears). I think it's a fairly common condition that comes with age.
I may have mislead you in my post. Didn't mean to say that the origin of tinnitus is in the aymgdala, but rather, it has a role to play in tinnitus. From what I have read, tinnitus doesn't have a single causation or origin. Current thinking is that, while tinnitus may stem from injury to the ear, it can also originate in the brain. For instance, there are many people who have no measurable hearing loss but still have tinnitus.
Here's one persespective.
Structural changes in the amygdala and the nucleus accumbens may also contribute to the emotional effects of tinnitus, as well as difficulties in sleep and selective attention. It is thought that auditory information ascends to the brain in two parallel pathways, and the "non-traditional pathway" bypasses the primary cortex and has strong/direct connections to the amygdala in the limbic system.
In other words, tinnitus may have a life of it's own, running on a neural pathway separate than the auditory one. As such, perception of tinnitus is both physiological as well as psychological. This is why methodologies such as TRT and Cognitive Behavior Therapy can be effective.
How are you doing with your T? Things going well?
