Atrophy involves the wasting of tissues due to catabolic processes exceeding anabolic synthesis, commonly classified into disuse and neurogenic types in skeletal muscle, as well as cerebral atrophy in neurodegenerative conditions. Molecularly, this wasting is driven by ubiquitin-proteasome and autophagy-lysosome pathways, with emerging research focusing on the muscle-brain axis and the impact of cognitive offloading.
