Types of Hearing Disorders
Age-related hearing loss (presbycusis) is the loss of hearing that gradually occurs in most of us as we grow older. It is one of the most common conditions affecting older and elderly adults. It is one of the most common conditions affecting older and elderly adults.
Auditory processing disorder (also known as central auditory processing disorder or CAPD) is a condition that makes it hard for kids to recognize subtle differences between sounds in words. It affects their ability to process what other people are saying. Here are the signs of auditory processing disorder (APD) and suggestions for how you can help your child.
Sometimes exposure to impulse or continuous loud noise causes a temporary hearing loss that disappears 16 to 48 hours later. Recent research suggests, however, that although the loss of hearing seems to disappear, there may be residual long-term damage to your hearing.
Ototoxic drugs should not be used for otic topical application when the tympanic membrane is perforated because the drugs might diffuse into the inner ear. Streptomycin tends to cause more damage to the vestibular portion than to the auditory portion of the inner ear.

Sensorineural hearing loss (SNHL) is a type of hearing loss, or deafness, in which the root cause lies in the inner ear or sensory organ (cochlea and associated structures) or the vestibulocochlear nerve (cranial nerve VIII). SNHL accounts for about 90% of reported hearing loss. SNHL is generally permanent and can be mild, moderate, severe, profound, or total.
The inner ear is the collection of structures within the bony labyrinth: the semicircular canals, the vestibule and the cochlea. Congenital abnormalities here are rare and will result in deafness in addition to possible dizziness, and account for up to 20% of children with sensorineural hearing loss.
The outlook for people with brain disorders depends on the type and severity of the brain disorder. Some conditions are easily treated with medication and therapy. For example, millions of people with mental disorders live perfectly normal lives. Other disorders, like neurodegenerative diseases and some traumatic brain injuries, have no cure.
