Tip: Beware precursors of serious communication disorders

About 20 percent of people older than 55 have a communication disorder, according to the American Speech-Language-Hearing Association. Some are normal parts of aging that may be prevented or controlled, but others may be precursors of serious conditions.

For example, if you repeatedly ask people to repeat themselves or find yourself turning up the volume on your TV or radio, that often is age-related hearing loss that can be treated. But if you suddenly experience trouble talking or if you have a problem with speaking that gets worse over time, that could be a warning sign of stroke.

For older people who complain about being hoarse, the association says this is usually not serious. Drinking lots of water may help treat or avert hoarseness. When in a conversation, don't compete with the TV or radio. Turn it down, or you may find yourself raising your voice and ending up hoarse.
