Question | Answer |

Functional Age | Actual Competence and performance may not match age |
Life expectancy | In North America there is lower infant mortality and lower adult deaths |
Group differences | Women live longer, SES, ethnicity and nationality |
White men and women at age 75 have a higher life expectancy then black men and women | Black men and women at age 85 and over have a higher life expectancy than white men and women |
Activities of daily living (ADLs) | Basic self-care tasks: bathing, dressing, eating |
Instrumental Activities of living (IADLs) | Conducting the business of everyday life, requiring cognitive competence, shopping, food prep, housekeeping |
Factors in long life: Environment and lifestyle | Normal weight, low substance use, exercise, optimism, low stress, social support, community involvement |
Aging and the Nervous system | -Loss of brain weight accelerates after age 60 -Neurons lost in frontal lobes, corpus collusm, cerebellum, glial cells -Autonomic nervous system less efficient |
Brain can compensate | new fibers, new neurons, new connections, use more parts of the brain |
Visual impairments and aging | lower visual acuity, poor dark adaptation, sensitivity to glare, decreased depth perception and color, cataracts, macular degeneration |
Visual hearing impairments | Men from under 45 to over 85 have more difficulties seeing and hearing than women under to over 85. |
Vision problems | Changes in leisure activities, problems, possible problems in daily activities |
Hearing loss | Social isolation, lower safety and enjoyment. |
Decreased taste and smell | Nutritional safety risks |
Less sensitive touch | Difficulties with leisure, daily activities |
Cardiovascular/Respiratory System | Heartbeat less forceful, slower heart rate, blood flow -Vital lung capacity cut by half -Less oxygen to tissues -Exercise helps |
Immune | Effectiveness declines, more infectious autoimmune diseases, stress-related susceptibility |
Sleep and aging | Needs less sleep, earlier bedtime and wake-up, more difficulties (insomnia, nighttime walking) |
Physical appearance and mobility | -Skin thinner, rougher wrinkled, spotted -Ears, nose, teeth change -Lose height and weight after 60 -Muscle strength declines -Bone strength drops -Less flexibility |
Adapting to physical changes to aging | -appearance vs functioning -Effective coping strategies (prevention and compensation, problem centered coping -Assistive technology -Overcoming stereotypes of aging |
Stereotypes of age |
