An 80 year old man develops bilaterally symmetric hearing loss which is gradual in onset. On examination he is found to have decreased hearing which is most prominent in the highest frequencies. A likely diagnosis is
a) Meniere's disease
b) Presbycusis
c) Multiple sclerosis
d) Acoustic neuroma
e) Usher's syndrome

b) Presbycusis
Presbycsis is the loss of hearing that gradually occurs in most individuals as they grow older. Hearing loss is a common disorder associated with aging. The loss associated with presbycusis is usually greater for high-pitched sounds.

Answer is B
Presbycusis is hearing loss associated with aging and is the most common cause of diminished hearing in the elderly. There are four types of presbycusis, distinguished according to the correlated pathologic changes in the cochlea. Hair cell loss and cochlear neuron degeneration are the most widely recognized changes. The hearing loss is bilaterally symmetric and gradual in onset. The majority of cases begin with a loss of the high frequencies with slow progression. Eventually, middle- and low-frequency sounds also become difficult to perceive.
