Until now, many people are still confused about tinnitus.
Currently, fifty million people from America alone are suffering from tinnitus to some degree.
So what are the causes of ringing in ears? One thing that is bothering the experts and the patients are the many different causes of tinnitus.
Tinnitus, on the other hand is a subjective experience.
There are some people who can endure and do not take it as something really serious.
However, there are also some people who are easily annoyed about a hearing sound that they hear even without any external physical sound.
This medical condition has been interconnected to a lot of medical, physiological and psychological conditions.
This makes it hard for them to pinpoint an exact cure.
Today, patients are still given treatments but the cause of the problem is carefully diagnosed beforehand.
The causes of tinnitus range from the most critical to the least serious conditions which you can expect.
But whatever the cause is, there's no doubt that this problem can deeply affect the way you think, act, do physical activities, sleep and many other things in your life.
Acoustic trauma or rejection of loud noise is a common root cause of tinnitus.
This is usually bilateral and is usually accompanied by hyperacusis.
Hyperacusis is a lowered tolerance to elevated levels of sound.
There are some who appreciate loud music and there are some who really hates it.
One's lower tolerance to sound means that he is more prone to tinnitus.
Head or nose injury can lead to serious cases of this problem.
These can trigger some abnormalities in nerve activities.
When nerves malfunction, these would interpret some activities within the brain as sound.
It usually leads to hearing impairment if taken for granted in the long run.
Out of all the causes of tinnitus, injury induced conditions are the hardest to cure.
Aging is definitely one of the most common causes of tinnitus.
As people age, they become more susceptible to anxiety, stress and they also get lower tolerance to sound.
According to studies, people start to lose cells that secrete glycine at the age of forty.
Glycine is the main inhibitory transmitter in the brain.
The important inhibitory signal of the brain is lost along with the diminishing amount of nerve fibers that carry glycine.
'Ringing ears' is produced as the brain cells start to fire without ample control.
Many people are unaware of the fact that dental problems are one of the causes of ringing in ears.
Impacted wisdom teeth, in particular, can trigger mechanical spasm in the jaw.
Further dental work with the help of the dentist or orthodontist can help cure the problem.
