This course is based on an article published by the National Institute of Aging: a division of the National Institute of Health. The publication can also be found on the National Institute of Aging website. The publication describes in detail the aging process covering what aging is exactly, the difference between life expectancy and life span and reviewing the theories on aging. It goes on to discuss in detail what is currently known about longevity genes, cellular senescence, proliferation genes and telomeres. The publication then reviews biochemistry and aging including oxygen radicals, protein crosslinking and DNA repair and synthesis. It describes normal aging, the immune system and its relationship in the aging process and what is known about the effects of caloric restriction and exercise on the aging process.
This is a wonderfully written article. The authors take complex subject material and simplify it with the aid of beautiful visual graphics that serve to aid the reader in understanding the material. This course is an excellent reference for the mental health professional that works with the elderly or is aging themselves.
Psychologists, social workers, mental health counselors, and marriage and family therapists can benefit from this course on aging and the elderly. This course may also be helpful for dieticians and nutritionists who work with geriatric or elderly clients. This course is appropriate for beginning, intermediate and advanced level practitioners who wish to develop their clinical skills with a geriatric or aging client population.
