Zika Can Result In Hearing Loss
Zika infection, which is spreading in many countries, can cause hearing loss. This occurs because Zika affects the brain, the stem, and the peripheral nerves. Since Zika affects also newborn babies, the procedure is to test for hearing and eyesight. More details click here.
Tinnitus Is Generated By The Brain, Not By The Ears
There Are Tests To Locate End Treat The Brain Areas That Originate It
Tinnitus is a perception of sound without an environmental source. It can happen in one or both ears. The sounds are similar to ringing, hissing, or buzzing and they may be constant or intermittent. Among the causes an acoustic neuroma, which is a benign tumor of the coating of the hearing nerve, or a dysfunction in the neuro-circuitry for hearing in the brain. This dysfunction may be located in the dorsal cochlear nucleus in the brainstem, which generates neurological activity spontaneously, and also can be located in non-auditory brain areas such as the frontal lobe, cerebellum, and the limbic system. There are procedures to evaluate treatments to stabilize these unhealthy regions of the brain, such as a neurological physical examination, VOG (video-oculography), audiometric testing (hearing tests), a computerized assessment of postural systems (CAPS) for balance, and imaging if necessary such as MRI.

Certain Sounds Cause An Extremely Negative Reaction To People
It Can Produce Anger, Anxiety, And Even Hypertension And Higher Heart Rate
There is a condition in which people react negatively to certain sounds. It is called misophonia, in which people overreact to determinate sounds, such as slurping drinks, tapping the fingers, or keyboard clicks, among others. Their reaction is disproportionate, and people are aware that they cannot control it. According to specialists, this aversion develops in childhood and gets worse over time. The reaction includes emotional responses, such as anger and anxiety, and also physiological responses, like hypertension and higher heart rate. It can also be caused by other conditions, such as tinnitus, OCD, or eating disorders. Consequences on sufferers include avoiding social situations and broken relationships.

Earwax Can Help Diagnose Certain Health Conditions
Ear wax can reveal certain health conditions related to hearing. However, first of all, we want to insist on NOT using Q-Tips for removing earwax, because it can affect the eardrums. That said, watery and green earwax is associated with excess sweating, but watery and dark yellow can be a sign of infection, together with a strong odor. Additional info click here.
Aphasia Not Only Related To Language And Hearing – Other Brain Areas Are Involved
Aphasia is a language disorder present in stroke patients in which the areas of the brain responsible for controlling hearing have been damaged. As a result, the patient has trouble hearing, understanding spoken words, speaking and even writing. It has been considered a language deficit disorder and treated as such. However, a recent study shows that other areas of the brain are involved, such as hearing, vision, executive functions such as control and planning, and motor processing. Additional info click here.
Tinnitus Or Ringing In Ears Can Be The Sign Of Serious Damage
Exposure to loud sounds is usually the cause of tinnitus. In some cases, it can last hours or even days. But if the exposure to high volume sounds continues, the sounds produced by tinnitus may become permanent. This can be a sign of damage to the auditory nerves or the hair cells.

Dementia Can Be Caused By Untreated Hearing Loss
Untreated hearing loss can affect other parts of the body. According to experts, the hearing process is 10 percent ear and 90 percent brain. In hearing loss, the brain does not get enough input and it starts to shut down the areas that deal with hearing, like muscle atrophy. This will eventually result in dementia. More info click here.
