"To give real service, you must add something which cannot be bought or measured with money, and that is sincerity and integrity." Douglas Adams

We are mission-driven, independent and not-for-profit. 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.

Keveyis Now Available Through Strongbridge Biopharma

Strongbridge Biopharma, a company which specializes in medications for rare diseases is now providing Keveyis (dichlorphenamide) to patients with periodic paralysis. Patients are provided one-on-one support through their dispensing pharmacy PantherX. Strongbridge is committed to making Keveyis available to all patients who need it. For more information on Keveyis and for some valuable forms and tips visit the Keveyis.com website.   

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.

There's a new and excellent article about Andersen-Tawil Syndrome from NORD, the National Organization for Rare Disorders. 

Andersen-Tawil syndrome is a rare genetic disorder characterized by episodes of muscle weakness and paralysis (periodic paralysis); abnormalities affecting the electrical system of the heart that can cause abnormal heart rhythms (arrhythmias); and a variety of distinctive facial and skeletal features. The specific symptoms and severity can vary greatly from one person to another, even among members of the same family. Some individuals will not develop all of the characteristic findings. Distinctive facial features may be so mild as to go unnoticed. In some cases, Andersen-Tawil syndrome is caused by mutations in the KCNJ2 gene; in other cases, the associated gene is unknown. The KCNJ2 gene mutation can occur randomly for unknown reasons (sporadically) or be inherited in an autosomal dominant manner.

The Empowered Patient

Trying to 'change the culture of medicine' by letting patients decide what gets researched; Patients can bring attention to issues they face that may not previously have been studied. A new approach to medical research in Canada lets patients help decide what gets studied, and how. No longer are scientists toiling away in labs in isolation. Patients and their family members or caregivers are increasingly involved behind the scenes, working alongside researchers, doctors and decision-makers at all stages of the research process. "Fairness and justice would say these people have got the disease … surely they should have a bit of a say," says Dr. Andreas Laupacis of Toronto's St. Michael's Hospital. As a health researcher at the Li Ka Shing Knowledge Institute, he's advocated that patients should be more involved in setting research priorities.

How many times have you needed, and not had, test results, or medical history you didn't have? It's Time to redesign medical data:

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.
