Does increased cellular autophagy in elders sometimes indicate dysfunctional ageing rather than health benefit?

A more skeptical reading treats elevated autophagy in elders as a possible stress signature or failed cleanup response rather than proof of resilience. In this view, senescent or diseased cells may activate autophagy to meet abnormal metabolic demands, while stalled lysosomal processing causes vesicle accumulation. The evidence is strongest as a warning against equating higher measured activity with better ageing, not as proof that increases are generally harmful.

• Higher autophagy markers may represent blocked processing and accumulated vesicles, not faster clearance or improved cellular health.
• Disease and senescence can hijack autophagy to meet increased metabolic demands and help maintain pathological states.
• Autophagy induction is not uniformly beneficial: experimental evidence links some induction, particularly with increased mitochondrial permeability, to harm.
• An age-related increase may be compensatory or stress-driven, so its significance must be judged alongside lysosomal function, disease state and completed flux.
