The Peripheral Slowing Hypothesis: What theory suggests that overall processing speed declines in the peripheral nervous system with increasing age?

According to a study published in 2023, electrodiagnostic tests confirm that aging is associated with decreased nerve conduction amplitudes, increased latency, and a slowing of conduction velocity in the peripheral nervous system. This supports the peripheral slowing hypothesis, a theory that suggests overall processing speed declines in the peripheral nervous system with increasing age.
