  • What is Periodic Paralysis? | Periodic Paralysis Intl. - The periodic paralyses are a group of rare inherited disorders that cause temporary episodes of muscle weakness or paralysis. Periodic Paralysis is found in all races and in both sexes. Some patients have their first attack within minutes of birth, but a few don't have symptoms until they are in their 60’s or 70’s. Attacks can last only a few moments or go on for days, depending on the type of periodic paralysis the person has. Some forms of periodic paralysis include muscle stiffness or rigidity as part of the attacks.
  • HKPP Listserv Page | Periodic Paralysis Intl. - We invite medically diagnosed patients to join the HKPP Listserv.  Our goals are:
  • Information for Patients and Caregivers | Periodic Paralysis Intl. - It is not easy to find medically accurate, up-to-date information about the periodic paralyses. This site contains two types of information; 1) that which is drawn directly from medical journals, textbooks and presentations by experts in the field of the periodic paralyses and 2) that which is drawn from surveying groups of diagnosed patients with periodic paralysis.
  • Information for Medical Professionals | Periodic Paralysis Intl. - This site contains information to guide the physician who cares for a patient with the primary ion channelopathy periodic paralysis, or who has a patient they suspect may have periodic paralysis. There are medically accurate, referenced articles on diagnostics, management, therapy plus informational material which may be printed and shared with patients. Periodic Paralysis can occur in many disorders. It is a challenge to separate primary from secondary causes, and to narrow the field from renal, autoimmune and adrenal disorders to a skeletal ion channelopathy.
  • Anaesthesia and peri-operative care in the primary Periodic Paralysis Disorders | Periodic Paralysis Intl. - 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 anesthesia 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.

  • The Membrane Potential, Voltage-Gated Ion Channels and Action Potentials | Periodic Paralysis Intl. - Action Potentials 1 - Resting Membrane Potential: This is the first tutorial in a series on Action Potentials. This video looks at how the Na+/K+ ATPase Ion Transporter sets up a voltage across a membrane. Action Potentials 2 - Voltage-Gated Ion Channels: This second tutorial looks at how the Voltage Gated Na+ & K+ Ion channels change the voltage across the membrane of a cell and thus produce an action potential.

  • Kish - The only nasal strip that stays on all night

    Breathe Right is the only brand of nasal strips that actually stay on all night. I have been cheap and lazy and purchased generic brands from Walgreens, WalMart, etc but they will not stay on. So I was pleased to see I could by these on Amazon Prime - no shipping or tax and lower cost than local stores. Have been using them on and off since they first came out. So worth it. I always use them at night and sleep so much better. I also use them in the day if I'm sick.
