|
Life Expectancy |
Average amount people of a cohort will live |
|
|
Life Span |
Maximum longetivity or oldest humans in general can live |
|
|
Compression of mortality |
Greater proportion of deaths will occur more towards the upper limit |
|
|
Compression of morbidity |
Only sickness and disease shortly before death |
|
|
Centenarians |
live to 100 |
|
|
Primary Aging |
Unavoidable biological processes that are universal |
|
|
Secondary Aging |
Results from disease and disuse |
|
|
The Programmed Theories of Biological Aging are... |
Aging is based off a genetically based blueprint
Time Clock Theory Immune Theory Evolutionary Theory |
|
|
Stochastic Theories are... |
Focus on random damage to our vital systems that occurs with the process of living, related to secondary aging
Error Theory Wear and Tear Theory Rate of living Theory Stress Theory Cross-Linking Theory Free radical theory |
|
|
Telomeres |
When too short, cell division is no longer possible and life span ends |
|
|
senescence |
When cells can no longer divide |
|
|
Error Theory |
Error occurs at a cellular level, resulting in faulty molecules |
|
|
Time Clock Theory |
Genetically determined time clock in humans |
|
|
Immune Theory |
Set to maintain efficiency for a certain amount of time, after it starts to decline |
|
|
Evolutionary Theory |
Once reproduction occurs, organism has filled it's duty so decline happens |
|
|
Rate of Living Theory |
Fixed amount of physiological energy` |
|
|
Stress |
In older adults HPA levels return back to normal slower than younger adults |
|
|
Free Radical Theory |
Unstable molecular fragments prevent normal molecules from doing their job |
|
|
Terminal Drop |
Steeper decline in the deceased individuals |
|
|
Reaction time is... |
a strong predictor of mortality |
|
|
Osteoporosis |
Extreme loss of bone |
|
|
Neuropsychology |
Study of brain-behavior relationships |
|
|
Scaffolding Theory of aging and cognition(STAC) |
When the brain builds alternative Neural Circuitry. These aren't as efficient as the young, but keep old brains working better. Can be maximized with cardio and challenging mental activities |
|
|
Density of Dendrites is.... |
Stimulated by the environment |
|
|
Activities of daily living (ADL) |
Basic Self Maitenance tasks Ex. Eating, bathing, dressing |
|
|
Instrumental Activities of Daily Living(IADL) |
More complex tasks ex. Shopping, Homework, preparing meals |
