The Cell Danger Response (CDR) provides an explanation and framework of understanding for chronic illnesses, including Idiopathic Parkinson’s Disease. According to this framework, the CDR occurs when a cell in the body detects a threat to its existence or that it is in some sort of mortal danger. When a cell thus loses its sense of safety, it moves via the CDR from contributing to the health and vitality of the body towards an “on guard” state of self-perseveration, and then alerts other cells to the danger by releasing chemicals, which can, in turn, set off their CDR, potentially leading to domino or cascade effect. If the threat is maintained long enough, eventually the CDR results in the cell going into a shut-down or hibernatory state, to wait it out until the danger has passed. When enough cells in the body get stuck in a Cell Danger Response, some from of chronic illness ensues.
