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.

  • Are you a Patient, Family Member, or Physician seeking information?
  • Are you interested in Membership in the PPA and access to our ListServ?
  • Would you like to ask a question of our Medical Advisors at “Ask the Experts” ?

These questions and more are answered within our site.  Please feel free to browse the menu on the left as well as our highlights at the bottom of this screen!  We welcome you to the PPA and will do our best to assist you as you search for answers about these rare diseases
