Gerontology is the study of the social, cultural, psychological, cognitive, and biological aspects of aging. a word was coined by Ilya Ilyich Mechnikov in 1903, from the Greek , geron, "old man" and -λογία, -logia, "study of". The field is distinguished from geriatrics, which is the branch of medicine that specializes in the treatment of existing disease in older adults. Gerontologists include researchers and practitioners in the fields of biology, nursing, medicine, criminology, dentistry, social work, physical and occupational therapy, psychology, psychiatry, sociology, economics, political science, architecture, geography, pharmacy, public health, housing, and anthropology.

The multidisciplinary generation of gerontology means that there are a number of sub-fields which overlap with gerontology. There are policy issues, for example, involved in government planning and the operation of nursing homes, investigating the effects of an aging population on society, and the array of residential spaces for older people that facilitate the development of a sense of place or home. Dr. Lawton, a behavioral psychologist at the Philadelphia Geriatric Center, was among the number one to recognize the need for living spaces intentional to accommodate the elderly, especially those with Alzheimer's disease. As an academic discipline the field is relatively new. The USC Leonard Davis School of Gerontology created the first PhD, master's and bachelor's degree entry in gerontology in 1975.

History

In the medieval Islamic world, several physicians wrote on issues related to Gerontology. Avicenna's The Canon of Medicine 1025 featured instruction for the care of the aged, including diet and remedies for problems including constipation. Arabic physician Ibn Al-Jazzar Al-Qayrawani Algizar, c. 898–980 wrote on the aches and conditions of the elderly. His scholarly hit covers sleep disorders, forgetfulness, how to strengthen memory, and causes of mortality. Ishaq ibn Hunayn died 910 also wrote works on the treatments for forgetfulness.

While the number of aged humans, and the life expectancy, tended to put in every century since the 14th, society tended to consider caring for an elderly relative as a generation issue. It was not until the coming of the Industrial Revolution that ideas shifted in favor of a societal care-system. Some early pioneers, such(a) as Michel Eugène Chevreul, who himself lived to be 102, believed that aging itself should be a science to be studied. Élie Metchnikoff coined the term "gerontology" in 1903.

Modern pioneers like National Institute on Aging – entry 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.

With the population of people over 60 years old expected to be some 22% of the world's population by 2050, assessment and treatment methods for age-related disease burden – the term geroscience emerged in the early 21st century.
