Q: What is the "invisible epidemic" among older adults in the United States? The Substance Abuse and Mental Health Services Administration has identified substance abuse among older adults as the "invisible epidemic" in the United States. The belief is that substance abuse often goes undetected in older adults, and there is concern about older adults who abuse not only illicit drugs but prescription drugs as well. Too often, screening questionnaires are not appropriate for older adults, and the consequences of alcohol abuse may erroneously be attributed to other medical or psychological conditions. Because of the dramatic increase in the number of older adults anticipated over the twenty-first century, substance abuse is likely to characterize an increasing number of older adults.

Q: Describe the major changes in physical appearance and movement in old age. In late adulthood, the changes in physical appearance that began occurring during middle age become more pronounced. Wrinkles and age spots are the most noticeable changes. We get shorter when we get older because of bone loss in our vertebrae. Our weight usually drops after we reach 60 years of age. This likely occurs because of muscle loss, which also gives our bodies a "sagging" look. Older adults move more slowly than young adults, and this slowing occurs for movements with a wide range of difficulty. One recent study of the functional ability of noninstitutionalized individuals 70 years of age and older revealed that over an eight-year period, the most deterioration occurred in their mobility.

Q: List three major findings from the Nun Study on aging.

Q: Identify and discuss the three major eye diseases that can impact the vision of older adults?

Q: Describe the major changes in sexual functioning among older males. Following are the changes observed in sexual functioning among older males: Orgasm becomes less frequent in males with age, occurring in every second to third attempt rather than every time. More direct stimulation usually is needed to produce an erection. From 65 to 80 years of age, approximately one out of four men have serious problems getting and/or keeping erections, and after 80 years of age the percentage rises to one out of two men. However, with recent advances in erectile dysfunction medications such as Viagra, an increasing number of older men, especially the young-old, are able to have an erection. Also, recent research suggests that declining levels of serum testosterone, which is linked to erectile dysfunction, can be treated with testosterone replacement therapy to improve sexual functioning in males. However, the benefit-risk ratio of testosterone replacement therapy is uncertain for older males.

Q: Define chronic disorders, and briefly describe the major chronic conditions affecting the older population.

Q: Discuss the cellular clock theory of aging. The cellular clock theory of aging is Leonard Hayflick's theory that cells can divide a maximum of about 75 to 80 times, and that as we age, our cells become increasingly less capable of dividing. Based on the ways cells divide, Hayflick places the upper limit of the human life-span potential at about 120 to 125 years of age. In the last decade, scientists have tried to fill in a gap in cellular clock theory. Hayflick did not know why cells die. The answer may lie at the tips of chromosomes, at telomeres, which are DNA sequences that cap chromosomes. Each time a cell divides, the telomeres become shorter and shorter. After about 70 or 80 replications, the telomeres are dramatically reduced, and the cell no longer can reproduce. One study revealed that healthy centenarians had longer telomeres than unhealthy centenarians. And recent studies even have found that shorter telomere length is linked to having worse social relationships, being less optimistic, and showing greater hostility.

Q: Discuss the free-radical theory of aging.

Q: Discuss the hormonal stress theory of aging.

Q: Describe shrinking of the brain in the aging process. On average, the brain loses 5 to 10 percent of its weight between the ages of 20 and 90. Brain volume also decreases. One study found that the volume of the brain was 15 percent less in older adults than younger adults. Some areas shrink more than others. The prefrontal cortex is one area that shrinks with aging, and recent research has linked this shrinkage with a decrease in working memory and other cognitive activities in older adults. Scientists think they might result from a decrease in dendrites, damage to the myelin sheath that covers axons, or simply the death of brain cells.

Q: What are people who are 85 years and older called?
