Many experts on aging prefer to describe the young-old, old-old, and oldest-old in terms of _________ rather than chronological age
functional age
85-year- olds are more _____ and _____ fit than some 65-year-olds
biologically & psychologically
This theory states that natural selection has not eliminated many harmful conditions and nonadaptive characteristics in older adults; thus, the benefits conferred by evolution decline with age.
Evolutionary Theory of Aging
is linked to reproductive fitness.
natural selection
cellular maintenance requirements and evolutionary constraints:
Cellular Clock/Telomere Theory
Free-Radical Theory
Mitochondrial Theory
Sirtuin Theory
mTOR Pathway Theory
Hormonal Stress Theory
It is Leonard Hayflick’s theory states that the maximum number of times that human cells can divide is about 75 to 80. As we age, our cells have less capacity to divide.
Cellular Clock/Telomere Theory
A microbiological theory of aging that states that people age because normal metabolic processes within their cells produce unstable oxygen molecules known as free radicals.
~ These molecules ricochet around inside cells, damaging DNA and other cellular structures.
Free-Radical Theory
the theory that aging is caused by the decay of mitochondria, tiny cellular bodies that supply energy for function, growth, and repair.
Mitochondrial Theory
A family of proteins (_____) that have been proposed as having important influences on longevity, mitochondria functioning in energy, calorie restriction benefits, stress resistance, and cardiovascular functioning.
Sirtuin Theory & Sirtuin
A cellular pathway involving the regulation of growth and metabolism that has been proposed as a key aspect of longevity
mTOR Pathway Theory
A theory that aging in the body’s hormonal system can decrease resistance to stress and increase the likelihood of disease.
Hormonal Stress Theory
The brain loses weight and volume with age, and there is a general slowing of function in the central nervous system that begins in middle adulthood and increases in late adulthood
THE SHRINKING, SLOWING BRAIN
older adults can generate ________, and at least through the seventies ______
new neurons & new dendrites.
The aging brain retains considerable plasticity and adaptiveness
THE ADAPTING BRAIN
It is the generation of new neurons, which does occur in lower mammalian species, such as mice.
Neurogenesis
can result in earlier death and lower cognitive functioning.
Poor sleep
Strategies to help older adults sleep better at night includes:
avoiding caffeine
avoiding over- the-counter sleep remedies
staying physically active during the day
staying mentally active
limiting naps
People get shorter as they age, and their weight often decreases after age 60 because of ______
loss of muscle
visual decline in late adulthood is linked to
(a) cognitive decline
(b) having fewer social contacts
(c) engaging in less challenging social/leisure activities
with aging, ________, ________, & _________ decline
visual acuity, color vision, and depth perception
Three diseases that can impair the vision of older adults are:
cataracts
glaucoma
macular degeneration
A thickening of the lens of the eye that causes vision to become cloudy, opaque, and distorted.
Cataracts
Damage to the optic nerve because of the pressure created by a buildup of fluid in the eye.
Glaucoma
A disease that involves deterioration of the macula of the retina, which corresponds to the focal center of the visual field.
Macular Degeneration
The yellowing of the eye’s lens with age reduces __________. The ability to see the ___________ also declines in older adults.
color differentiation & periphery of a visual field
decline can begin in middle age but usually does not become much of an impediment until late adulthood.
Hearing
is linked to declines in activities of daily living, cognitive functioning, and language.
Hearing loss
A perceptual motor coupling characterizes older adults; driving a vehicle is an example of this coupling.
➤ Two types of interventions in improving older adults’ driving:
Cognitive training
Education
a disorder that increase in late adulthood.
Cardiovascular disorders
a disorder that increase in late adulthood.
Cardiovascular disorders
Consistent high blood pressure should be treated to reduce the risk of ________, _______ _______, and _______ ______.
stroke, heart attack, and kidney disease
The most common chronic disorder in late adulthood is ______
arthritis
the main reason many older adults walk with a stoop; women are especially vulnerable to this condition
Osteoporosis
inflammation of the joints accompanied by pain, stiffness, and movement problems; this disease is especially common in older adults
Arthritis
a chronic condition that involves an extensive loss of bone tissue and is the main reason many older adults walk with a marked stoop
Osteoporosis
unintended injuries are the eighth leading cause of death among older adults
Accidents
Researchers who study exercise and aging have made the following discoveries:
[1] Exercise is linked to increased longevity
[2] Exercise is related to prevention of common chronic diseases.
[3] Exercise is associated with improvement in the treatment of many diseases.
[4] Exercise improves older adults’ cellular functioning.
[5] Exercise improves immune system functioning in older adults.
[6] Exercise can optimize body composition and reduce the decline in motor skills as aging occurs.
[7] Exercise reduces the likelihood that older adults will develop mental health problems and can be effective in the treatment of mental health problems.
[8] Exercise can reduce the negative effects of stress in older adults
[9] Exercise is linked to improved brain, cognitive, and affective functioning in older adult.
Four aspects of nutrition are especially important in older adults:
[1] Getting adequate nutrition.
[2] Avoiding overweight and obesity.
[3] Deciding whether to restrict calorie intake to improve health and extend life.
[4] Determining whether to take specific vitamin supplements to slow the aging process.
Being _______ is linked to health problems, and being _______ predicts earlier death.
overweight & obese
these can slow the aging process and improve older adults’ health
antioxidants vitamin C, vitamin E, and beta-carotene
taking _______ ______ ______ does not reduce the risk of cancer and cardiovascular disease
antioxidant vitamin supplements
_____ is a multidimensional concept
Cognitive functioning
Cognitive mechanics are “_________” of the mind that may decline with age due to biological factors
hardware
Cognitive pragmatics are “_______” of the mind that may improve with age due to cultural factors
software
factors that contribute to the decline in fluid mechanics in late adulthood:
Declines in processing speed, working memory capacity, and inhibition
these refer to the neurophysiological processes involved in sensory input, attention, memory, and categorization, which are likely to decline with age due to biological and health factors.
Cognitive Mechanics
these refer to culture-based skills such as language comprehension, education, and life
skills, which can continue to improve even in old age due to their experiential and cultural foundation.
Cognitive Pragmatics
fluid intelligence reflecting _______ ______ and crystallized intelligence reflecting ___________
cognitive mechanics & cognitive pragmatics
decline during aging due to biological and genetic factors.
Cognitive mechanics
do not decline until individuals become very old.
Cognitive pragmatics
Four types of attention are :
selective attention
divided attention
sustained attention
and executive attention.
