Programmed theories of aging
Theories of biological aging that emphasize the systematic genetic control of aging processes
Damage theories of aging
Theories of the biology of aging that emphasize random, haphazard errors and damage associated with such processes as the production of free radicals as explanations of why we all age and die.
Maximum life span
Theories of the biology of aging that emphasize random, haphazard errors and damage associated with such processes as the production of free radicals as explanations of why we all age and die.
Hayflick Limit
The estimate that human cells can double only 50 times, plus or minus 10, and then will die.
Telomeres
A stretch of DNA that forms the tip of a chromosome and that shortens after each cell division, serving as an aging clock and timing the death of cells.
Epigenetic aging clock
A measure of patterns of DNA methylation that are closely associated with aging.
Free radicals
Chemically unstable byproducts of metabolism that have an unpaired electron and react with other molecules to produce toxic substances that damage cells and contribute to aging.
Antioxidants
Vitamins C, E, and similar substances that may increase longevity, although not for long, by inhibiting the free radical activity associated with oxidation and in turn preventing age-related diseases.
Caloric restriction
A technique demonstrated to extend the life span of laboratory animals involving a highly nutritious but severely calorie-restricted diet.
Denial
A defense mechanism in which anxiety-provoking thoughts are kept out of, or isolated from, conscious awareness.
Bereavement
A state of loss that provides the occasion for grief and mourning.
Grief
The emotional response to loss.
Mourning
Culturally prescribed ways of displaying reactions to a loss.
anticipatory grief
Grieving before death for what is happening and for what lies ahead.
Parkes/Bowlby Attachment Model of Bereavement
Model of grieving describing four predominant reactions to loss of an attachment figure: numbness, yearning, disorganization and despair, and reorganization.
Dual-process model of bereavement
A theory of coping with bereavement in which the bereaved oscillate between loss-oriented coping in which they deal with their emotions, restoration-oriented coping in which they try to manage practical tasks and reorganize their lives, and periods of respite from coping.
Loss-oriented coping
In the dual-process model of bereavement, coping focused on dealing with one’s emotions and reconciling oneself to the loss.
Restoration orientated coping
In the dual-process model of bereavement, coping focused on managing daily living, rethinking one’s life, and mastering new roles and challenges
Complicated grief
An emotional response to a death that is unusually prolonged or intense and that impairs functioning; pathological grief.
Disenfranchised grief
Grief that is not fully recognized or appreciated by other people and therefore may not receive much sympathy and support, as in the loss of a gay partner.
