"The term refers mainly to humans, many other animals, and fungi, whereas for example, bacteria, perennial plants and some simple animals are potentially biologically immortal."
The physical, cognitive, and social changes that occur during later life.
Gerontology: The study of aging in all its aspects, including physiological, psychological, social, and economic.
Developmental Psychology: The study of how human beings develop from birth to old age, including the processes of physical, cognitive, and emotional growth.
Epidemiology: The study of the distribution and determinants of health and disease in populations, including the aging population.
Neurobiology of Aging: The study of the structure and function of the aging brain and nervous system, including age-related changes in cognitive and sensory abilities.
Longevity: The study of living longer and healthier, including factors and interventions that promote healthy aging.
Social Gerontology: The study of aging within the context of aging societies, including the social and historical forces that shape the experiences of older adults.
Clinical Geriatrics: The study of medical care for older adults, including common health problems and approaches to prevention and treatment.
Nutrition and Aging: The study of the role of diet and nutrition in healthy aging, including dietary recommendations for older adults.
Aging and Retirement: The study of retirement from the labor force and the impact of retirement on physical and psychological health.
End-of-Life Care: The study of medical care for people at the end of life, including hospice care, palliative care, and ethical considerations.
Health and Well-Being: The study of aging and health, including physical and mental aspects of well-being and the role of lifestyle factors in maintaining good health.
Ageism: The study of age discrimination, including the negative attitudes, stereotypes, and practices that contribute to ageism.
Environmental Gerontology: The study of the physical environment and aging, including how urban design and architecture can promote healthy aging.
Health Disparities and Inequities: The study of disparities in health outcomes and access to health care among older adults based on race, ethnicity, income, and other factors.
Technology and Aging: The study of the role of technology in improving the quality of life and health outcomes for older adults, including assistive technology and telehealth.
Biological Aging: Aging caused by changes in the structure and function of organs and tissues.
Cultural Aging: Aging that is influenced by cultural beliefs or values.
Psychological Aging: Changes in mental processes or functioning as a result of aging.
Social Aging: Aging caused by societal factors, such as social expectations or changes in social roles.
Chronological Aging: Aging that is measured by the passage of time.
Functional Aging: Decline in the ability of the body and mind to function normally.
Cellular Aging: Aging at the cellular level, including damage to DNA and telomeres.
Wear-and-Tear Aging: Aging caused by the accumulation of damage caused by daily living.
Immunologic Aging: Changes in the immune system that occur with aging.
Neurological Aging: Changes in the nervous system associated with aging.
Menopausal Aging: Aging associated with changes in hormone levels, especially as women approach and experience menopause.
Reproductive Aging: Aging associated with changes in fertility and reproductive function.
Attitudinal Aging: Changes in attitudes or beliefs about aging and older adults.
Environmental Aging: Aging caused by exposure to environmental pollutants or toxins.
Accumulative Aging: Aging that occurs as a result of cumulative stress or damage to the body over time.
"In humans, ageing represents the accumulation of changes in a human being over time and can encompass physical, psychological, and social changes."
"Reaction time, for example, may slow with age, while memories and general knowledge typically increase."
"Ageing increases the risk of human diseases such as cancer, Alzheimer's disease, diabetes, cardiovascular disease, stroke and many more."
"Current ageing theories are assigned to the damage concept, whereby the accumulation of damage (such as DNA oxidation) may cause biological systems to fail."
"Programmed ageing should not be confused with programmed cell death (apoptosis)."
"Obesity has been proposed to accelerate ageing."
"Dietary calorie restriction in non-primate animals slows ageing while maintaining good health and body functions."
"In primates (including humans), such life-extending effects remain uncertain."
"For example, bacteria, perennial plants and some simple animals are potentially biologically immortal."
"Of the roughly 150,000 people who die each day across the globe, about two-thirds die from age-related causes."
"The internal processes (epigenetic maintenance such as DNA methylation) inherently may cause ageing."
"Ageing increases the risk of human diseases such as cancer, Alzheimer's disease, diabetes, cardiovascular disease, stroke and many more."
