![]() ![]() Over 30 percent of bacterial meningitis results in some form of hearing loss. Meningitis can be bacterial, viral, fungal or parasitic. Meningitis is the inflammation of thin tissue (meninges) surrounding and covering the brain and the spinal cord. Vertigo caused by neck disorders is called cervical vertigo. If two tumours develop on both hearing nerves because of genetic disorder, it is termed neurofibromatosis. The tumour becomes life threatening when it starts pressing against the brain. It grows slowly pressing against the hearing and the balance nerves. The body’s immune cells damage the myelin sheath that surrounds and protects the nerve cells thus blocking the messages between the brain and the body.Īcoustic neuroma, also called vestibular schawannoma, is a benign tumour that develops on the nerve which connects the ear to the brain. Multiple sclerosis is an autoimmune disease that affects the nervous system, that is, the brain and the spinal cord. This causes the neck muscles and ligaments to push beyond their normal range of motion. Whiplash is a neck injury caused by acceleration – deceleration forces as in automobile collisions in which the neck and the head suddenly moves backward and then forward. It usually affects just one ear and is the common cause of hearing loss. Meniere’s disease is a chronic disorder of the inner ear. Otitis media is a middle ear infection and usually occurs in children along with cold and flu. It can occur suddenly and for a short time which is then called acute otitis or it can occur repeatedly over long periods of time which is called chronic otitis. Otitis is the infection or inflammation of the inner or outer parts of the ear. Otosclerosis is a condition in which there is an abnormal bone growth in the middle ear that causes hearing loss. This is an irreversible condition since the damage is caused by degeneration of sensory cells which occurs with age. For example, it more commonly hits people who work in noisy environments, or listen to constant loud music, or maybe are frequent clubbers.Īge related hearing loss is called presbycusis. One of the most common reasons you may hear ringing in your ears or head is when you are exposed to loud noise over extended periods of time. Here we describe the most common causes of tinnitus. Tinnitus can actually be caused any number of reasons ranging from noise induced hearing loss to nerve disorders to side effects of certain medications. But before we look into the causes of tinnitus, let’s understand how sound travels through the ear and how the typical tinnitus sound is produced. ![]() Tinnitus may have different causes but mainly it results from hearing disorders and the most probable cause is noise induced hearing loss. Tinnitus, a chronic ringing or buzzing in the ears makes brain restless.Teachers' Day 2018: 5 common health conditions teachers can suffer from.Firecrackers: 10 reasons why they are health hazards. ![]() This stimulates abnormal activity in the neurons, which results in the illusion of sound, or tinnitus. So, the brain doesn’t receive the signals it is expecting. When hair cells are damaged, that is, bent or broken, they can leak electrical impulses to the brain. These signals then travel to the brain’s auditory cortex via the auditory nerve. There are tiny delicate hairs in your inner ear which move according to the pressure of sound waves and help transform sound waves into electrical signals. Sound waves travel from outside through the outer ear to the ear canal, and from there to the middle and inner ear. The sound varies some people may hear it as a hissing sound, others like a tea kettle whistling, or a sort of electricity noise, or even as humming. It is difficult to describe the sound of tinnitus through language. Thankfully, it’s not a serious health disorder but it can be one of the most distressing ear problems, causing various physical and psychological disorders that interfere with the quality of life. In other words, tinnitus is a perception of sound in the absence of an actual external sound. Scientists define it as ‘a perception of sound without corresponding acoustic or mechanical correlates in the cochlea’. Tinnitus, ringing in the ear, the annoying constant noise in the head. ![]()
