- Pathological aging is the aging process that is brought on by the presence of disease, such as adult-onset diabetes or arthritis, and that may later bring on cardiovascular disease or osteoporosis. This is not considered normal aging. These conditions are due to heredity or lifestyle.

- 1 Such as the 'wear and tear' theory where body tissue becomes worn from use and cannot continuously renew itself. 2  The rate-of-living theory suggests that rapid expenditure of energy precipitates early aging and slow expenditure results in slower aging.rogrammed Cellular Aging Theory. 1  Suggests that aging may be a result of an impairment of the cell in translating necessary RNAs as a result of increased turnoffs of DNA. 2  In other words, the transcription of these messages into functional proteins may be restricted in older people.

Ageing Ageing (British English) or aging (American English) is the process of becoming older. In the narrow sense, the term refers to biological ageing of human beings, animals and other organisms.

gerontology Gerontology is concerned with the changes that occur in the cells, tissues and organs of the body with age, with the natural limits of cell reproduction, the causes of natural cell death, the effects of life style and physical activity on longevity and the psychological and sociological effects of ageing. ger·on·tol·o·gy.

- Frailty is not really a disease but rather a combination of the natural aging process and a variety of medical problems. It is a little like the classic definition of pornography — experts may disagree on exactly what it is but most people know frailty when they see it.

Life extension Life extension science, also known as anti-aging medicine, indefinite life extension, experimental gerontology, and biomedical gerontology, is the study of slowing down or reversing the processes of aging to extend both the maximum and average lifespan.

Aging Aging, progressive physiological changes in an organism that lead to senescence, or a decline of biological functions and of the organism’s ability to adapt to metabolic stress. 1  Aging takes place in a cell, an organ, or the total organism with the passage of time. It is a process that goes on over the entire adult life span of any living thing. Gerontology, the study of the aging process, is devoted to the understanding and control of all factors contributing to the finitude of individual life.

Ageing Ageing or aging (see spelling differences), is the process of becoming older. The term refers especially to human beings, many animals, and fungi, whereas for example bacteria, perennial plants and some simple animals are potentially immortal.

Ageing Ageing (British English) or aging (American English) is the process of becoming older. In the narrow sense, the term refers to biological ageing of human beings, animals and other organisms.In the broader sense, ageing can refer to single cells within an organism (cellular senescence) or to the population of a species (population ageing).ccumulation of Misrepairs is focalized and self-accelerating. Focalized accumulation of Misrepairs leads to the development of spots or plaques in a tissue, such as atherosclerotic plaques and age spots in skin. Thus, development of aging changes is inhomogeneous and self-accelerating.

- Organic or pathological disease are terms used to describe more advanced stages of disease that are accompanied by physical, cellular changes that can be identified by diagnostic testing. Examples of organic diseases include cancer, arthritis, heart disease, gastric ulcers, and emphysema. Too often, diseases are diagnosed when they are more advanced, end-stage organic diseases.

Aging Psychosociological theory. In addition to theories of aging based on molecules and cells, there also exists a “psychosociological” theory of aging. As people grow older, their behaviour changes, their social interactions change, and the activities in which they engage change.

Aging Longevity is the span of life of an organism. Aging is the sequential or progressive change in an organism that leads to an increased risk of debility, disease, and death. Senescence consists of these manifestations of the aging process.

Panama Canal During construction, ownership of the territory that the Panama Canal now passes through was first Colombian, then French, and then American. The US continued to control the canal and surrounding Panama Canal Zone until the 1977 Torrijos–Carter Treaties provided for handover to Panama.

Pathological, Abnormal Anxiety When the intensity, duration, and/or frequency of anxiety become distressful and chronic, such that it interferes with a person's functioning, it is often referred to as pathological anxiety.Anxiety disorders represent variant forms of this pathological anxiety.hese three factors-duration, intensity, and frequency-distinguish normal, adaptive anxiety from abnormal, pathological anxiety. As such, abnormal anxiety is different from normal anxiety because it is disproportionate to the situation that elicited the anxious response.

Pathological Lying: Symptom or Disease? There is, as yet, no consensus in the psychiatric community on its definition, although there is general agreement on its core elements. PL is characterized by a long history (maybe lifelong) of frequent and repeated lying for which no apparent psychological motive or external benefit can be discerned.

Human aging Human aging, physiological changes that take place in the human body leading to senescence, the decline of biological functions and of the ability to adapt to metabolic stress. In humans the physiological developments are normally accompanied by psychological and behavioural changes, and other changes, involving social and economic factors, also occur. 1  Aging begins as soon as adulthood is reached and is as much a part of human life as are infancy, childhood, and adolescence.

gerontology Gerontology. a division of medicobiological science that studies the phenomena of aging in living organisms, including man. The subdivisions of gerontology are geriatrics (the study of the diseases of the senescent organism), geriatric hygienics (the study of the hygiene of the elderly), and gerontological psychology. The study of gerontology was developed with the essential changes in man’s life expectancy.

Free-radical theory of aging The free radical theory of aging (FRTA) states that organisms age because cells accumulate free radical damage over time.A free radical is any atom or molecule that has a single unpaired electron in an outer shell.While a few free radicals such as melanin are not chemically reactive, most biologically-relevant free radicals are highly reactive. free radical is any atom or molecule that has a single unpaired electron in an outer shell.

Ageing In humans, ageing represents the accumulation of changes in a human being over time, encompassing physical, psychological, and social change. Reaction time, for example, may slow with age, while knowledge of world events and wisdom may expand.
