Ep. 28: Paralyzer

About this episode

This episode explores Periodic Paralysis, a rare condition that causes temporary paralysis triggered by various factors.

You've heard of paralysis. But what if it came and went, triggered by rest, a meal, or exercise, and left no trace by morning? This week, Andrea walks Crystal through Periodic Paralysis, a rare and frequently misdiagnosed group of channelopathies that can leave patients unable to move for hours at a time. We break down how ion channels gone wrong can bring an otherwise healthy person to a complete standstill, why it often takes years to get a correct diagnosis, and what living with this condition actually looks like. Medicine doesn't always look the way we expect. Sometimes the most dramatic symptoms vanish before anyone can see them.
