Late adulthood Flashcards
As more individuals are living healthier lives and medical discoveries are slowing down the aging process, middle age appears to be _______ and ______
starting later & lasting longer
late middle age is?
55-65
middle age is a time of declining physical skills-such as?
loss of height
impaired vision and hearing
reduced cardiovascular functioning
_____ also becomes more problematic.
Sleep
_______ the maximum number of years an individual can live.
Life Span
________ the number of years that will probably be lived by the average person born in a particular year
Life Expectancy
individual 100 years and older.
Centenarians
individuals 110 to 119 years and older.
Supercentenarians
In 2018, who is oldest living person in the world for 117-year-old
Nabi Tajima of Japan
Who is the oldest living person in the United States for 114-year-old?
Delphine Gibson of Pennsylvania
Factors that are responsible for such longevity in Okinawa, Japan:
[1] Diet
[2] Low-stress lifestyle
[3] Caring community
[4] Activity
[5] Spirituality
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.
