About 30% of patients with periodic paralysis have unknown genetic mutation, making identification and treatment a challenge. Here: key points on genetics, testing, and subtypes of PPP.

Because symptoms of periodic paralysis may overlap with other neurological or medical conditions and genetic testing is not always routinely available, exercise test methods can be key.

A recent study has suggested that a substance called Hm-3, which is derived from crab spider toxin, may pave the way for new treatments for a subtype of the rare neuromuscular disorder, primary periodic paralysis.
