Um, Phil did Iron Maiden drive you a bit insane? Or let me put it this way; ARE YOU NUTS? Of course you have tinnitus you just can’t hear it anymore!

Parkinson's Daily reported the following:
Parkinson disease arises from decreased dopamine production in the brain. The absence of dopamine makes it hard for the brain to coordinate muscle movements. Low dopamine also contributes to mood and cognitive problems later in the course of the disease. Experts don’t know what triggers the development of Parkinson disease most of the time. Early onset Parkinson disease is often inherited and is the result of certain gene defects.

Why Do I Have This Noise In My Ears
Although we hear tinnitus in our ears, its source is really in the networks of brain cells that make sense of the sounds our ears hear. A way to think about tinnitus is that it often begins in the ear, but it continues in the brain.

Scientists still have not agreed upon what happens in the brain to create the illusion of sound when there is none. Some think that tinnitus is similar to chronic pain syndrome, in which the pain persists even after a wound or broken bone has healed.Tinnitus could be the result of the brains neural circuits trying to adapt to the loss of sensory hair cells by turning up the sensitivity to sound. This would explain why some people with tinnitus are oversensitive to loud noise.

Tinnitus also could be the result of neural circuits thrown out of balance when damage in the inner ear changes signaling activity in the auditory cortex, the part of the brain that processes sound. Or it could be the result of abnormal interactions between neural circuits. The neural circuits involved in hearing are not solely dedicated to processing sound. They also communicate with other parts of the brain, such as the limbic region, which regulates mood and emotion.

Please talk to your doctor about this issue since so little is known about it and any relationship with PD.

I have had tinnitus for years. The volume increased drastically a few months after diagnosis. I sleep with a fan on to help drown out the noise. It definitely helps.

I’ve had tinnitus since 1984. I was seen at Mayo Clinic and had 3 days of every test they could think of; I also would have periodic attacks of severe dizziness. The final diagnosis was vestibular hydrops; it all went into remission but the tinnitus which I was told was common. At that time I was told they did not have cause except it was associated with damage to my inner ears. But you know how things change; this week it’s one thing and next week it’s changed because they have knew information.

I have read that it can be an early indicator of Parkinson's. My tinnitus started 3 months prior to when other symptoms began.
