The word was coined by Ilya Ilyich Mechnikov in 1903, from the Greek γέρων, geron, "old man" and -λογία, -logia, "study of". Notably, in the United States and across the world, the "baby boomer" generation began to turn 65 in 2011. Free radicals are reactive molecules produced by cellular and environmental processes, and can damage the elements of the cell such as the cell membrane and DNA and cause irreversible damage. An increase in cellular apoptosis may correlate to aging, but is not a 'cause of death'. view of continuity starts with the idea of a basic A., & Dulmus, C. N.
Aging is part of the development sequence of the entire life span, from prenatal growth to senescence. The free-radical theory of aging proposes that this damage cumulatively degrades the biological function of cells and impacts the process of aging.
This leads to aging and will eventually lead to death. More recently epigenetics have been explored as a contributing factor. However, proportionately, the Northeast contains the largest percentage of adults aged 65 years and older (14.1%), followed by the Midwest (13.5%), the South (13.0%), and the West (11.9%). [4] His scholarly work covers sleep disorders, forgetfulness, how to strengthen memory,[5][6] and causes of mortality[7] Ishaq ibn Hunayn (died 910) also wrote works on the treatments for forgetfulness (U.S. National Library of Medicine, 1994). Programmed cell death, or apoptosis, is determined by a "biological clock" via genetic information in the nucleus of the cell. [51], Study of the social, psychological and biological aspects of aging, Geographic distribution of older adults in the United States, CS1 maint: multiple names: authors list (, VickyRN. Accordingly, continuity theory [9], Modern pioneers like James Birren began organizing gerontology as its own field in the 1940s, later being involved in starting a US government agency on aging – the National Institute on Aging[10] – programs in gerontology at the University of Southern California and University of California, Los Angeles, and as past president of the Gerontological Society of America (founded in 1945).
The activity theory is applicable for a stable, post-industrial society, which offers its older members many opportunities for meaningful participation. Geroscience is a recently formulated interdisciplinary field that embraces biomedical gerontology as the center of preventing diseases of aging through science.[24].
[16] An example of an accumulation theory is the Free Radical Theory of Aging. To the extent that past, change is a part of continuity. general areas of life in which these principles could The hardening of the connective tissue, kidney diseases, and enlargement of the heart are connected to the cross-linking of proteins. The notion of accumulated damage was first introduced by Weisman as the "wear and tear" theory. Relative to the Census 2000, all geographic regions demonstrated positive growth in the population of adults aged 65 years and older and 85 years and older. This static view of continuity is not very applicable change builds upon, and has links to, the person's
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. In 1900, there were 3.1 million people aged 65 years and older living in the United States. Advantages and disadvantages in early life stages have a profound effect throughout the life span. introduction of the concept of time, ideas such as
Accumulation theories of aging suggest that aging is bodily decline that results from an accumulation of elements, whether introduced to the body from the environment or resulting from cell metabolism.
consider the implications for how societies might function when age-based It makes it possible for society to continue functioning after valuable older members die.
[8], While the number of aged humans, and the life expectancy, tended to increase in every century since the 14th, society tended to consider caring for an elderly relative as a family issue.
Due to these internal and external insults, cells lose their ability to regenerate, which ultimately leads to mechanical and chemical exhaustion. are supported by both individual preference and ways. (August 2, '09). According to this theory, older adults' self-concept depends on social interactions. 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. A key assumption of this theory is that older adults lose "ego-energy" and become increasingly self-absorbed.
Gerontologists include researchers and practitioners in the fields of biology, nursing, medicine, criminology, dentistry, social work, physical and occupational … aging could be expected to follow, explanations of
[23], Biomedical gerontology, also known as experimental gerontology and life extension, is a sub-discipline of biogerontology that endeavors to slow, prevent, and even reverse aging in both humans and animals. The basic structure is Gerontology is the science of aging and geriatrics is a medical discipline that deals with the diagnosis, treatment, care, rehabilitation, but also prevention of diseases in the elderly, which are, by definition of the World Health Organization all persons older than 65 years of age. Therefore, the sex ratio is the number of males per 100 females. It involves interdisciplinary research on biological aging's causes, effects, and mechanisms. It is important to note the difference between geriatrics, the care of aged peo… There are numerous theories of aging, and no one theory has been accepted. This information should not be considered complete, up to date, and is not intended to be used in place of a visit, consultation, or advice of a legal, medical, or any other professional. Gerontology is broader than geriatrics, which is the medical specialty devoted to treatment and care of older people (seniors health).

The total population increased by 9.7%, from 281.4 million to 308.7 million, between 2000 and 2010. Precisely, the natural environment (such as natural therapeutic landscapes, therapeutic garden) contributes to active and healthy aging in the place. Social gerontologists may have degrees or training in social work, nursing, psychology, sociology, demography, public health, or other social science disciplines. Using theories such as therapeutic jurisprudence, jurisprudential scholars critically examined existing legal institutions (e.g. [36], Disengagement theory was developed by Cumming and Henry. The configurations and content of other life stages are being altered as Élie Metchnikoff coined the term "gerontology" in 1903. direction, sequence, character development, and

[16], The immunological theory of aging suggests that the immune system weakens as an organism ages.
differentiate that structure from others. [46] Studies of environmental gerontology indicate that older people prefer to age in their immediate environment, whereas spatial experience and place attachment are important for understanding the process.
The cells and tissues are eventually injured due to the damage gathered over time.
