The Periodic Paralysis Association (PPA) welcomes you to our non-profit organization!

Periodic Paralysis is a group of disorders whereby patients become weak due to triggers such as rest after exercise or certain foods.  These disorders are part of a broader class of disorders called ion channelopathies, in which a genetic defect in a muscle ion channel results in symptoms of episodic stiffness or weakness in response to certain triggers.
