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…
The Compound Muscle Action Potential (CMAP) test (aka the Exercise EMG) is used to diagnose the periodic paralyses. When done correctly this test is reported to positively identify 70%-80% of patients. The CMAP test is based on the observation that patients with Periodic Paralysis have a greater than normal increase in the compound muscle action…
Submitted by deb on Sat, 06/25/2011 – 19:16 What happens during an attack of Periodic Paralysis? People with Periodic Paralysis (PP) have episodes in which their muscles become weak or paralyzed in response to variations in the amount of potassium in their blood. These variations occur during sleep, they may result from food the person has eaten,…
