2
Q

These theories of aging are related to genetics and hypothesize that the differences in aging process is due to genetics ( interplay bet. mutation & natural selection)

3
Q

In this theory, oxidative stress (free radical combines w/ another molecule resulting to oxidative process)can disrupt cell membranes and alter DNA and protein synthesis

This suggests that more mutations occur with aging can ultimately lead to functional failure

Q

This theory avers that over time and as a result of exposure to chemicals and radiation in the environment, cross-links from between lipids, proteins, and carbohydrates, and nucleic acids.

3
Q

This theory suggests that aging occurs due to declining force of natural selection with age.

Meaning, genetic mutations that appear late in life will accumulate bcs older individuals they affect already passed this mutations to their offspring

Q

What are examples of Nonstochastic Theory? (7)

A
  1. Apoptosis
  2. Genetic theory
  3. Autoimmune reactions
  4. Neuroendocrine & Neurochemical theory
  5. Radiation theory
  6. Nutrition theory
  7. Environmental theory
3
Q

This theory proposes that genetic program predetermines life span

A

GENETIC THEORY

3
Q

This theory proposes declining functional capacity of immune system as the basis for aging

A

AUTOIMMUNE REACTIONS THEORY

3
Q

This proposes that there is an impairment in the ability of the cell to continue dividing.

Hence, programmed cell death is part of the normal aging process

A

APOPTOSIS

3
Q

Propose that aging occurs because of functional decline in neurons and associated hormones

A

NEUROENDOCRINE & NEUROCHEMICAL THEORY

3
Q

This theory proposes that deficiency in vitamins (and proper nutrition) causes aging

A

NUTRITION THEORY

3
Q

This theory proposes that health threats are associated with aging

A

ENVIRONMENTAL THEORY

4
Q

It describes that aging is based on culture

A

SOCIOLOGIC THEORY OF AGING

5
Q

The basis of this this theory is that human being are mortal and must be looking for replacement

A

DISENGAGEMENT THEORY

6
Q

This theory is about decrease functionality

A

ACTIVITY THEORY

6
Q

This theory talks about aging is due to phases of life cycle

A

CONTINUITY THEORY

7
Q

This theory talks about thriving

A

THEORY OF THRIVING

7
Q

It suggests that aging is focused on transcendence vision (wisdom)

A

GENOTRANSCENDENCE

7
Q

This theory suggests that society is stratified by age groups, shared tradition, practices

A

AGE STRATIFICATION THEORY

7
Q

it describes the process of healthy psychological aging as the result of successful fulfillment of developmental task

A

THEORY OF DEVELOPMENTAL TASKS

7
Q

Suggests that there is acceptance to certain group, and not accepted in some especially for older adults

A

SUBCULTURE THEORY

7
Q

This theory advocates wellness to older adults

A

FUNCTIONAL CONSEQUENCES THEORY

7
Q

This theory utilizes Roy’s Adaptation Model

A

THEORY OF SUCCESSFUL AGING
