Patients with Hyperkalemic PP (HyperKPP) develop paralysis or weakness (and sometimes muscle stiffness) when they eat potassium-rich food. This is also referred to as ‘potassium sensitive’ periodic paralysis. This is usually called Hyperkalemic Periodic Paralysis because most patients’ potassium levels rise during attacks. HyperKPP is due to a mutation in the sodium channel. Hyperkalemic Periodic…
Submitted by deb on Sat, 06/25/2011 – 02:45 What is Hyperkalemic Periodic Paralysis? Hyperkalemic Periodic Paralysis (HyperKPP) is a rare inherited muscle disorder which causes episodes of paralysis or weakness. It’s estimated to occur in only one of 250,000 individuals, though since it is inherited there may be several patients in a single family. It was only…
Submitted by deb on Tue, 06/28/2011 – 21:14 Clinical Signs Hyperkalemic Periodic Paralysis is a genetically determined disorder which causes attacks of weakness and flaccid paralysis. Attacks last from 10 min to 1 hour, very rarely up to 1-2 days. Some patients experience only a few attacks over their lifetime, others have attacks every day. Diagnosis is…
Submitted by ian on Tue, 06/21/2011 – 22:55 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…
Submitted by deb on Tue, 04/12/2016 – 22:54 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…

Submitted by deb on Sat, 07/02/2011 – 18:02 Introduction: The major features found in all the periodic paralyses are: 1. Attacks almost always begin before the age of 25, though occasionally later in life. ATS patients can develop first symptoms at any age. 2. Serum potassium fluctuates shortly before an attack, but serum potassium level will normalize…
