PHYSICAL DEVELOPMENT IN LATE ADULTHOOD
The young-old and the oldest-old
Oldest-old face many problems (physical and mental disabilities (high level of frailty,increased in loneliness) Young-old substantial potential for physical and cognitive fitness
Biological theories of aging
Evolutionary theory of aging proposes that natural selection has not eliminated many harmful conditions and non adaptive characteristic in older adult.
Among the key genetic and cellular processes that have been proposed to explain aging are those involving telomeres, free radicals, mitochondria, sirtuins and the mTOR pathway.
Life expectancy and Life span
Life span - The maximum number of years an individual can live.
Life expectancy - The number of years that will probably be lived by the average person born in particular year (Differs for various ethnic, because of powerful influence of education)
The Course of Physical Development in Late Adulthood
Physical appearance and movement
Wrinkles and age spots becomes noticeable, shorter because bone loss their vertebrae, weight usually drops
Vision Acuity (difficulty in seeing), Color Vision (yellowing of the lens of the eye.) Depth Perception (difficult to determine how close or far ,low or high something is.), Diseases of the eye (cataracts, glaucoma and macular degeneration)
Smell and Taste
decline more sense of smell than sense of taste
Touch and pain
Lower pain sensitivity but only for lower pain intensities-can help cope with disease and injury but also mask injuries and illnesses that need to be treated.
Perceptual Motor Coupling
Learning new things become difficult
They have difficulty sleeping, engaged in more light sleep and less deep sleep, easily disrupted
The circulatory and respiratory system
Using various drugs, a healthy diet and exercise can reduce the risk of the diseases.
The aging brain
The Shrinking, Slowing Brain
A general slowing of function in the brain and spinal cord begins accelerates - Physical coordination and Intellectual performance are affected.
The Adapting Brain
The brain loses only a portion of its ability to function and the activities older adults engage in can influence the brain's development.
sexually active as long as they are healthy
Exercise, nutrition and weight
Set exercise goals then carrying out an exercise plan
-Getting adequate nutrition
-avoiding overweight and obesity
-deciding whether to restrict calorie
intake to improve health and extend life
-determining whether to take specific
vitamin supplements to slow aging process.
Nursing home care - The patient will get privacy, access to medical information, safety and lifestyle freedom within the individual's range of mental and physical capabilities.
Substance use and abuse
Do not overdosing
Inflammation of the joints accompanied by pain, stiffness and movement problems.
A chronic condition that involves an
extensive loss of bone tissue and
is the main reason many older
adults walk with a marked stoop
Causes of death in older adults
Cancer or cardiovascular disease (Ethnicity)
Accidents ( unintended injuries )
