Periodic Paralysis and the New Mother

Anticipating the Baby

 

Expectant mothers and their doctors can take the secure thought that hundreds of women with periodic paralysis have been members of our Listserv since 1995, and an overwhelming majority of them have been mothers. To date not a single one has been unable to care for her child due to her periodic paralysis.

Irm's Story

The PPI's Client Services Representative in The Netherlands is Irm. Irm and her son were clinically diagnosed with HypoKPP-plus in Germany in September 2011, but she has had symptoms since she was a young child. At the age of 7, she told her parents, “My head is awake but my body still sleeps”. 

Physician's Reading Room

How is periodic paralysis diagnosed?

Do you suspect that you might have periodic paralysis? The periodic paralyses are a rare group of disorders and there are many conditions which cause an imbalance in serum potassium. So how does the doctor tell the difference between paralysis or weakness caused by an ion channelopathy and any of the other numerous disorders, conditions and reactions which might produce the same symptoms?

Management Strategies For Hypokalemic Periodic Paralysis

In 2009 Professor Dr. Frank Lehmann-Horn of Ulm University, Ulm Germany, gave a presentation on managing hypokalemic periodic paralysis at the Periodic Paralysis Association's conference held in Orlando Florida. This presentation contained so much valuable information in such a compact and understandable format that we asked Dr. Lehmann-Horn for his permission to include it on our website, for the benefit of physicians and patients.

Emergency Care for an Attack of Andersen-Tawil Syndrome

First Actions:

  • Respiratory and cardiac arrest are possible.
  • Call for Cardiac Monitoring/EKG
  • Draw electrolytes to determine serum K+
  • Provide 02 as thimble may not reflect 02 saturation due to cardiac dilitation
  • Lie patient in coma position to avoid aspiration.
