Hearing impairment among older adults is often mild or moderate, yet it is widespread almost 25 percent of adults aged 65–74 and 50 percent aged 75 and older have hearing impairment that is often isolating.People 55 and older account for over a quarter of all Americans diagnosed with HIV, and this number is increasing.Four chronic conditions - heart disease, cancer, stroke, and diabetes - cause almost two thirds of all deaths among individuals 65 and older each year.Approximately 92 percent of older adults have at least one chronic condition, and 77 percent have two or more.Many are active and healthy, whereas others are frail, with multiple health conditions. However, just as all older adults are not the same, their health status also varies. As they age, people are generally more satisfied with their lives and more optimistic about growing older.Ī number of physical changes and health issues are more common as we age.Approximately 5 percent of individuals between 71 and 79 and 37 percent of the population above age 90, are affected. Dementia (including Alzheimer’s disease, the most common type of dementia) is not a normal part of aging.The number of older adults with substance abuse problems is expected to double to five million by 2020.The suicide rate for men over 85 is higher than that of any other age group.However, one in four older adults experiences a mental health problem such as depression, anxiety, schizophrenia or dementia. Most older adults report good mental health and have fewer mental health problems than other age groups.For example, people who were outgoing during young adulthood are likely to be outgoing in later life. Personality traits remain relatively stable over time.Wisdom and creativity often continue to the very end of life.However, many older adults outperform their younger counterparts on intelligence tests that draw on accumulated knowledge and experience. The speed with which information is encoded, stored, and retrieved also slows as we age. Some changes in cognition are normal with age, such as slower reaction times and reduced problem-solving abilities.Short-term memory shows noticeable changes with age, but long-term memory declines less with age.Older adults are capable of learning new skills even late in life, though learning may take longer than for younger adults.For most older adults, age-associated changes in cognition (thinking) are mild and do not significantly interfere with daily functioning.has increased by 70 percent in the last 20 years, from 2.7 million to 4.6 million.

It can go through either a physical or chemical change.Many assume that older adults are all alike.
