What is Periodic Paralysis?
Primary Periodic Paralysis (PPP) is a group of rare genetic disorders characterized by recurring episodes of mild to extreme muscle weakness, stiffness, or paralysis. These episodes may vary from affecting a single limb to the entire body, and can last several minutes, hours, or days. What triggers an episode varies from patient to patient and may be caused by a variety of factors such as stress, eating certain foods, consuming alcohol, resting after exercise, sleep, becoming chilled or overheated. Symptoms of PPP can manifest at any age but most commonly begin during childhood or puberty.
There are four different forms of PP all involving defects in ion channels. Ion channels are gateways that let charged minerals (ions) such as sodium and potassium flow into and out of your muscle cells. This flow of ions is a central part of what makes our muscles work. In PP the ion channels have flaws, flow is disrupted, causing an imbalance. The muscle cells then fail to contract or relax in response to the nerve signals.
The Four Types of Periodic Paralysis:
- Hypokalemic Periodic Paralysis
- Hyperkalemic Periodic Paralysis
- Anderson-Tawil Syndrome
- Thyrotoxic Periodic Paralysis

We invite you to participate in our web-based events held throughout the year. These events provide excellent opportunities to connect with other members, stay updated on the latest information from experts specializing in Periodic Paralysis, and hear insights from Rare Disease Advocates. We value your input, so please feel free to email us and let us know which topics are important to you. We welcome your suggestions for discussion and sharing within our community.
In Person Regional and Local Group Support Meetings.
One of our goals is to connect you with other PPP Patients in your vicinity by creating in-person local or regional support meetings.

Honoring our founders, the Greant Family, and the late Don Anderson
Without the lifelong dedication of Deb and Ian Greant as well as the Late Don Anderson the Periodic Paralysis International along with and the creation of HKPP.org would not have existed. Their countless hours of research working closely with the late Dr. Frank Lehmann-Horm over the years generated a wealth of the documentation resources made available to the public. Their invaluable work not only advanced research efforts but also improved understanding of this rare and often misunderstood group of diseases. Their relentless pursuit of answers and dedication to providing support to a community of people often shunned has earned them a place as pioneers in the field of PP. The Periodic Paralysis International will forever be grateful.
