Breathing Muscle Weakness

Neuromuscular-Induced

Neuromuscular-induced respiratory muscle weakness is a type of respiratory impairment caused by the muscles used for breathing becoming weakened as a result of the underlying neuromuscular disease. In neuromuscular diseases that can affect breathing, the muscles responsible for breathing can become weakened, resulting in a reduced ability to fully expand the chest cavity with each breath. In turn, this leads to a reduced ability to fully inflate the lungs, which is the definition of hypoinflation. Throughout this process, lung and airway tissues remain healthy. Examples of diseases that can cause neuromuscular-induced respiratory muscle weakness include Multiple Sclerosis (MS), Myasthenia Gravis (MG), and CMT.

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.
