Our website reflects our mission to make medically accurate, up-to-date information about the periodic paralyses accessible to patients, caretakers and physicians.

Our goal is to help create successful partnerships between physicians, researchers and periodic paralysis patients in order to speed diagnosis and improve therapy and management strategies, thereby improving quality of life and clinical outcomes for patients.

Anaesthesia and Periodic Paralysis

April 12, 2016: Adverse reactions to anaesthesia, including life-threatening events, are a serious concern for patients with Periodic Paralysis Disorders. Many of our patients report serious events associated with anaesthesia and side effects which may linger for days to months. There is rarely time for a surgical team to comb through journals and texts for the specialized knowledge needed to care for the patient with periodic paralysis.

In order to make this information easier to find retired Haemato-oncologist and ATS patient Dr. Annabelle Baughan, PPI Director Deb Cavel-Greant, HKPP Listserv member Jan Magalo, and Neurologist Dr. Frank Weber have prepared both a Literature Review and a set of Practical Guidelines physicians may consult when caring for a patient with one of the Periodic Paralyses. A new tab has been added to the menu bar at the top of the page to make these articles immediately available when needed. Check them out.

FDA Approves Taro’s Keveyis™ (dichlorphenamide) for Primary Hyperkalemic and Hypokalemic Periodic Paralysis

This Orphan Drug is the first approved treatment for patients living with this category of rare debilitating diseases, and our community owes a huge debt of gratitude to Dr. Jacob Levitt, President of the Periodic Paralysis Association, who has worked tirelessly for the last 15 years to bring this treatment to market. Without his committment and hard work we would never had access to this, one of the most effective treatments many of us have ever had. Thank you Dr. Jake! You are our HERO!   yes

One of the most vital aspects of staying healthy when you have periodic paralysis is becoming an informed and empowered patient. When Dave deBronkart learned he had a rare and terminal cancer, he turned to a group of fellow patients online — and found the medical treatment that saved his life. Now he calls on all patients to talk with one another, know their own health data, and make health care better one e-Patient at a time.

Apnea Board.com

Sleep apnea is a sleep disorder characterized by abnormal pauses in breathing or instances of shallow breathing during sleep. Each pause in breathing, called an apnea, can last from a few seconds to minutes, and may occur 5 to 30 times or more an hour. Similarly, each shallow breathing event is called a hypopnea. Sleep apnea is diagnosed with an overnight sleep test called a polysomnogram, or "sleep study". From reports of Listserv members it appears patients with periodic paralysis may be at higher risk of sleep apnea than average. If you have been diagnosed with sleep apnea, or suspect you have sleep apnea, Apnea Board.com is the place to find reliable information.
