What is Periodic Paralysis?

Primary periodic paralysis is a rare genetic disorder that involves periods of muscle weakness or paralysis. It can be hypokalemic, triggered by too little potassium in the body, or hyperkalemic, triggered by too much potassium. Symptoms can also include heart or breathing problems, muscle stiffness, and altered body temperature.

Treatment may include potassium supplements or medications intended to lower levels of potassium. Carbonic anhydrase inhibitors like Keveyis can help keep potassium levels balanced.
