Theories Of Aging. Proponents of this theory point to the control of puberty which is initiated by the hypothalamus through the pituitary hormones as proof that the brain can be programmed to function in this way. Proponents of disengagement theory hold that mutual social withdrawal benefits both individuals and society. One of the most recent theories regarding gene damage has been the telomerase theory of aging. Gene theory which considers aging to be the result of a sequential switching on and off of certain genes with senescence being defined as the time when age associated deficits are manifested.
In this theory it is the binding of glucose simple sugars to protein a process that occurs under the presence of oxygen that causes various problems. This theory suggests that biological aging is due to the fact that normal cells cannot divide indefinitely this is known as the hayflick limit and is evidenced in cells studied in test tubes which divide about 40 60 times before they stop bartlett 2014. Provide a broad definition for psychosocial theories of aging. Two major theories explain the psychosocial aspects of aging in older adults. It is not that the cells die. Gene theory which considers aging to be the result of a sequential switching on and off of certain genes with senescence being defined as the time when age associated deficits are manifested.
One of the most recent theories regarding gene damage has been the telomerase theory of aging.
Neuroendocrine theory this theory holds that aging is programmed in the brain at birth and these cells directs the process by hormonal and neural influences. Gene theory which considers aging to be the result of a sequential switching on and off of certain genes with senescence being defined as the time when age associated deficits are manifested. Disengagement theory views aging as a process of mutual withdrawal in which older adults voluntarily slow down by retiring as expected by society. Nevertheless one of the most popular theories is the free radicals or oxidative stress theory of aging which hypothesizes that an accumulation of reactive oxygen species hereafter ros falls. First discovered by scientists at the geron corporation it is now understood that telomeres the sequences of nucleic acids extending from the ends of chromosomes shorten every time a cell divides. This shortening of telomeres is believed to lead to cellular damage due to the inability of the cell to duplicate itself correctly.
