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 results from missing or damaged sensory cells (hair cells) in the cochlea and is usually permanent. Also known as ânerve deafnessâ, sensorineural hearing loss can be mild, moderate, severe or profound. Mild to severe sensorineural hearing loss can often be helped with hearing aids or a middle ear implant.
