The following major hormones are involved with aging: Estrogen decreases the thinning of bones, and when women age, less estrogen is produced by the ovaries. As women grow older and experience menopause, adipose tissue becomes the major source of estrogen. Growth hormone is part of the process that increases bone and muscle strength. Growth hormone stimulates the release of insulin-like growth factor produced by the liver. Melatonin is produced by the pineal gland and is thought to be responsible for coordinating seasonal adaptations in the body. There is a higher chance of excess or loss of glucocorticoids, aldosterone, androgens, triiodothyronine, thyroxine, and parathyroid hormone when the hypothalamus-pituitary-endocrine gland feedback system is altered. When the stimulating and releasing hormones of the pituitary and the hypothalamus are out of synch with the endocrine glands, an increase in disease is expected in multiple organs and systems. Of significance are the findings of Rodenbeck and Hajak , who cited that, with physiological aging and also with certain psychiatric disorders, there is increased activation of the

hypothalamus-pituitary-adrenal axis, which causes increased plasma cortisol levels. The increased cortisol levels can be linked with several diseases. Immunologic/Autoimmune Theory: Normal aging process of humans and animals as being related to faulty immunological function. There is decreased immune function in elderly due to: The thymus gland shrinking. Altered lymphocyte function. Decreased cell mediated and humoral immune response. There is loss of T-cell differentiation, so body incorrectly perceives old, irregular cells as foreign bodies and attacks them. There is an increase in certain autoantibodies such as rheumatoid factor and a loss of interleukins. Implications for Nursing: Nursing Theories of Aging: Functional Consequences Theory: Developed to provide a guiding framework for older adults with physical impairment and disability. Created by Miller . Aging adults experience environmental and biopsychosocial consequences that impact their functioning. Nurse’s Role is To: Assess age-related changes and accompanying risk factors. To design interventions that minimize age-associated disability. Goal: maximize functioning in ways that improve patient safety and quality of life. Quality of life, functional capacity and dependency are connected and that positive consequences are possible despite age-related limitations. Theory of Thriving: Explains the experience of nursing home residents. Newbern and Krowchuk suggested that difficulty with social relationships (disconnectedness and inability to find meaning in life, give of oneself, or attach to others) and physical/cognitive dysfunction (consistent unplanned weight loss, signs of depression, and cognitive decline) were related to a failure to thrive. Theory of Successful Aging: Flood proposed that aging well is defined by the extent to which older adults adapt to the cumulative physical and functional changes they experience. Moreover, a person’s perception about how well he or

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
