Welcome to Periodic Paralysis International!
Our website reflects our mission to make medically accurate, up-to-date information about the periodic paralyses accessible to patients, caretakers and physicians.
Our goal is to help create successful partnerships between physicians, researchers and periodic paralysis patients in order to speed diagnosis and improve therapy and management strategies, thereby improving quality of life and clinical outcomes for patients.
