Types of Hypokalemic periodic paralysis

Types discussion:

The two most common types of periodic paralyses are hypokalemic (caused by mutations in the calcium channel gene on chromosome 1) and hyperkalemic (caused by mutations in the sodium channel on chromosome 17). Hypokalemic periodic paralysis, which is often referred to as familial, is characterized by a fall in potassium levels in the blood. Hypokalemic attacks are usually triggered by exercising too strenuously, eating too many carbohydrates, or taking drugs such as insulin. Attacks of hypokalemic periodic paralysis begin in adolescence and may last for a few hours or persist for several days. Some patients may develop a fixed muscle weakness later in life. Hyperkalemic attacks, which are frequent and brief (lasting 1 to 2 hours), are usually triggered by strenuous exercise, stress, ingestion of certain foods, and administration of potassium. Individuals with hyperkalemic periodic paralysis may display a rise in potassium levels in the blood during attacks. Some attacks may be accompanied by myotonia (the inability to immediately relax a contracted muscle). Hyperkalemic attacks often begin at an early age (infancy to early childhood). Heart arrhythmias may also develop during these attacks in some families. (Source: excerpt from NINDS Periodic Paralyses Information Page: NINDS)
