How is periodic paralysis diagnosed?

Do you suspect that you might have periodic paralysis? The periodic paralyses are a rare group of disorders and there are many conditions which cause an imbalance in serum potassium. So how does the doctor tell the difference between paralysis or weakness caused by an ion channelopathy and any of the other numerous disorders, conditions and reactions which might produce the same symptoms?

Emergency Treatment of Thyrotoxic Hypokalemic Periodic Paralysis


A True Endocrine Emergency

Patients with Thyrotoxic Hypokalemic Periodic Paralysis typically present at the ER with an acute episode of paralysis involving the muscles of the extremities and limb girdles. The lower limbs are more frequently and severely involved than the upper. Weakness may be asymmetrical. Proximal strength is more severely impaired than distal strength. Respiratory and cardiac arrest are possible. Lie patient in coma position to avoid aspiration.

Emergency Treatment of Thyrotoxic Hypokalemic Periodic Paralysis

First Actions:

  • Respiratory and cardiac arrest are possible. 
  • Call for Cardiac Monitoring/EKG
  • Draw electrolytes to determine serum K+
  • Thyroid studies
  • Provide 02 as thimble may not reflect 02 saturation due to cardiac dilitation
  • Lie patient in coma position to avoid aspiration.

Diet for Patients with Hypokalemic Periodic Paralysis

Designed by the National Institutes of Health    

This information is based on a diet designed at the National Institutes of Health in the 1960s for a young man with Hypokalemic Periodic Paralysis (HypoKPP). According to the NIH physicians and dietician Mary R. Emerson, plus many other medical authorities, those with HypoKPP should follow a diet which is high in protein, low in carbohydrate, and low in sodium.

Thyrotoxic Hypokalemic Periodic Paralysis

Clinical Synopsis

Thyrotoxic periodic paralysis (THKPP) is an uncommon disorder characterized by simultaneous thyrotoxicosis, hypokalemia, and paralysis that occurs primarily in males of Asian descent, including patients of Japanese, Chinese, Vietnamese, Korean and Filipino ancestry.

Meal Plan Template

When I'm in the middle of an abortive attack meal planning goes right out the window. I can look at a fridge and pantry full of food and not be able to figure out what to do with any of it.

The only way to avoid feeding the family cheese on toast and a glass of tap water for dinner again is advance planning.

I can follow clear and simple directions. So if I plan exactly what we will eat for each meal I can;

1) avoid wasting food,

2) feed us something other than crud on rice (which is going to make me weak anyway) and
