Parkinson ' s Disease in the SENS View of Damage Repair

The Strategies for Engineered Negligible Senescence (SENS) is a view of aging as accumulated damage. Drawing from the extensive scientific literature on aging, the originators of SENS created an outline of the forms of cell and tissue damage that are fundamental causes of aging, in that they occur as a natural side-effect of the normal operation of our cellular biochemistry. So we might consider the loss of vital cells due to declining stem cell function, mutations to nuclear DNA and mitochondrial DNA, cross-linking of vital molecules in the extracellular matrix, accumulated metabolic waste in long-lived cells, generation of amyloids from misfolded proteins, and the accumulation of senescent cells, for example. These forms of damage accumulate to cause other, downstream forms of damage and dysfunction that, collectively, give rise to degenerative aging and age-related mortality. Aging is a very complex in its details, but only because cellular biochemistry is very complex. Complex systems malfunction in response to damage in complex ways, but the root causes of aging, the forms of damage noted above, are much less complex and thus much easier to visualize, describe, and intervene in. Because SENS specifies the forms of damage in some detail, it also describes what needs to be done in order to reverse the progression of aging: repair the damage. Removing damage that is disruptive to cell and tissue function allows cell and tissues to improve their function and re...
