Hypokalemic Periodic Paralysis – Causes, Symptoms & Treatment

by andywalsh | December 22, 2019 9:05 pm

Hypokalemic periodic paralysis is an inherited disorder that causes occasional episodes of muscle weakness. During an attack of periodic paralysis, muscles do not respond to normal nerve impulses or even to artificial stimulation with an electronic instrument. The person remains completely awake and alert. The precise form that the disorder takes varies in different families.

In some families, the paralysis is related to high levels of potassium in the blood (hyperkalemia); in others, the paralysis is related to low levels of potassium in the blood (hypokalemia) or, rarely, to normal levels. Some people may have episodes almost every day, while others experience them weekly, monthly, or only rarely.

Attacks can occur without warning or can be triggered by factors such as rest after exercise, a viral illness, or certain medications. Often, a large, carbohydrate-rich meal or vigorous exercise in the evening can trigger an attack upon waking the following morning. Although affected individuals usually regain their muscle strength between attacks, repeated episodes can lead to persistent muscle weakness later in life.

Causes of Hypokalemic Periodic Paralysis

Periodic paralysis is a congenital condition that is, it is present from birth. Familial periodic paralysis is inherited but may occur without a known family history. The inherited form of the disorder is autosomal dominant, which means that only one affected parent is needed to transmit the gene to the baby. When one parent is affected, the child has a 50% chance of getting the disease. Rarely, the condition occurs as a result of a non-inherited genetic defect.
