SNAP

Sensory Nerve Action Potential

The sensory nerve action potential (SNAP) is the electrical response recorded from a sensory nerve when it is stimulated during a nerve conduction study. It reflects how many sensory nerve fibers are working and how well they conduct, which makes it one of the most sensitive measures of peripheral nerve function. In CMT, the SNAP is often reduced or absent, an early sign of the disease’s effect on the sensory nerves.

Jean-Martin Charcot lecturing at the Salpêtrière while comparing anatomical illustrations of a cavovarus Charcot-Marie-Tooth (CMT) foot and a Charcot neuroarthropathy foot, highlighting two different conditions that share the Charcot name.


A Name That Does Too Much Work

Jean-Martin Charcot's name appears throughout medicine, but nowhere does it create more confusion than in the foot. Learn why the CMT foot and Charcot neuroarthropathy, also known as Charcot foot, share a name yet differ in how they develop, appear, and are managed.

When Medicine Lost Its Compass

Evidence failed not because it was wrong, but because it was weaponized. I lived the downstream effects of that failure for more than a decade. This is what happens when medicine forgets that data always ends in a human being.

Error 404: Gene Not Found

CMT genetic testing often fails to identify the cause of the disease, even when comprehensive panels are used. Here, we discuss why this happens, what genetic tests can and cannot do, and why a negative result still matters.
