A detailed examination of recent progress from the SENS Foundation: "Recent years have seen both substantial progress, and significant frustration, in the preferred regenerative engineering approach to the treatment and prevention of Alzheimer's disease (AD), and the eventual regeneration of genuinely youthful cognitive function: immunotherapeutic clearance of beta-amyloid (AmyloSENS). ... results appear to many to commend an earlier window of opportunity for intervention, before concomitant [damage] and neuronal losses have made the removal of beta-amyloid alone insufficient for cognitive rescue. Early intervention might also maximize the therapeutic window for vaccination, preventing the burden of beta-amyloid neuropathology from ever reaching levels so high as to interact with other forms of aging damage in already frail and immunosenescent people." Present work on immune therapies for clearing unwanted biochemical junk from the body looks promising - there is every sign that today's advances will broaden into a general technology platform for this purpose. Researchers will be able to develop therapies that can be applied incrementally throughout life to remove the age-related gunk like beta-amyloid before it rises to dangerous levels.
