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 before the attacks resolves and will be within the normal range between attacks. This is not a disorder of the blood but one in which there is an inappropriate shift of fluid, K+ and NA+ during attacks.

When evaluating patients for periodic paralysis it is vital to obtain accurate results from blood draws. Because potassium levels which vary only a fraction of a point may be enough to trigger weakness in some patients, the lab may need to be made aware of specialized procedures which should ideally be used to obtain samples for K+ evaluation.

Potassium (K+) Normal Values: 3.5-5.0 mmol/liter 4.0-4.7 mmol/liter (average)

Acetazolamide (aka Diamox) is frequently prescribed as therapy for the periodic paralyses. While most patients take this drug without incident it can interact with other drugs. Physicians should be aware of potential problems which might arise.

The use of local anaesthetics on patients with periodic paralysis presents some unusual challenges. Many patients report that these agents trigger weakness or paralysis, a phenomenon which is substantiated in medical literature. Some patients also report that the agents do not produce the desired anaesthesia.
