See the list below:

  • Hyperkalemic periodic paralyses and paramyotonia congenita

    • When not associated with weakness, these usually do not interfere with ability to work.

    • Myotonia may require treatment.

    • Life expectancy is not known to be affected.

  • Hypokalemic periodic paralyses

    • Untreated patients may experience fixed proximal weakness, which may interfere with activities.

    • Several deaths have been reported, mostly related to aspiration pneumonia or inability to clear secretions.
