Shingles is caused by the varicella-zoster virus â the same virus that causes chickenpox. Anyone who's had chickenpox may develop shingles. After you recover from chickenpox, the virus can enter your nervous system and lie dormant for years.
Hearing loss, also known as hearing impairment, is a partial or total inability to hear. A deaf person has little to no hearing. Hearing loss may occur in one or both ears. In children hearing problems can affect the ability to learn spoken language and in adults it can cause work related difficulties.
Sensorineural Hearing Loss. Permanent hearing loss occurs when inner ear nerves become damaged and do not properly transmit their signals to the brain. Those who suffer from this condition may complain that people seem to mumble or that they hear, but do not understand, what is being said. The aging process is a very common cause of sensorineural hearing loss. As we get older, the inner ear nerves and sensory cells gradually die.
