Monitoring vision and hearing keep elderly engaged in the world around them

In turn, that changes how older people function and interact with others, sometimes with unfortunate consequences.
Seniors may withdraw from friends and family, becoming isolated and depressed, because they can't understand what people are saying to them.
They may be unable to see clearly at night upon awakening, and trip and fall on their way to the bathroom.
The label on a pill bottle may be impossible to read — the type is so small! — and older adults may take too many or too few pills without knowing it.
When a senior is having problems hearing and asks the same question repeatedly, he or she may be mistaken as having short-term memory loss or dementia.
A doctor's instructions may be unattended because they weren't clearly heard. Without sensory stimulation, an older adult may begin to lose mental alertness and responsiveness.
Often, vision and hearing problems go unrecognized because symptoms come on gradually over time and doctors don't inquire about them.
"Sensory impairments in the elderly are routinely overlooked," says Margaret Wallhagen, director of the John A. Hartford Center of Geriatric Nursing Excellence at the University of California, San Francisco.
For many older adults, these difficulties, especially hearing problems, are a source of embarrassment or shame.
"It's a symbol of 'I'm old' and people don't want to confront that," Wallhagen said.
Warning signs can include an older relative who says "no" every time he or she is invited out to a restaurant or a family gathering; someone who stops reading or watching TV or, conversely, turns up the volume on the TV full-blast; an older man or woman who repeatedly asks "What did you say?" or who doesn't seem to be paying attention to a conversation; and a relative who expresses some concern about driving at night, experts say.
The most common cause of vision loss in adults over 65 is "refractive error" (a problem with focusing light) and this frequently can be corrected by getting new glasses, said Dr. Jane Potter, chief of geriatric medicine at the University of Nebraska.
She recommends that adults over age 65 have an eye examination every other year to check for abnormalities in vision, including glaucoma and cataracts, which also become more common with age.
A common cause of hearing loss is impacted ear wax, which can be cleaned out in a doctor's office. Technological advances have made hearing aids more effective, and cochlear implants are a good alternative for older adults with profound hearing loss, Potter said.
She recommends hearing tests for seniors every five years unless serious symptoms surface earlier.
Families can help by recognizing a loved one's impairment and making adaptations. Sometimes family members compensate by becoming a "go-between" for an older relative with hearing problems, "telling them everything that's going on around them," Wallhagen said. While well-intentioned, this strategy can diminish the older person's alertness and should be used cautiously, she recommends.
The bottom line: Don't accept a senior's poor vision or hearing as "normal" for their age. Have them medically evaluated, and research products and devices that can help. Even small changes can make a big difference.
