In medical terms, primary periodic paralysis is referred to as a spectrum of chronic genetic, neuromuscular disorders with autosomal dominant inheritance.3
Primary periodic paralysis is very rare, affecting about 4,000 to 5,000 diagnosed individuals in the United States.4 Although there are related variants, the most common forms are hyperkalemic and hypokalemic PPP.5-9
Paralytic attacks result from loss of muscle membrane excitability10
Clinical attacks vary widely2:
Time between disease onset and diagnosis is often delayed and can take more than 20 years1,2
|May be precipitated by environmental triggers (ie, foods rich in potassium or carbohydrates, rest after exercise, exposure to cold, and emotional stress)1,10,11|
|Acute attacks of flaccid paralysis may be focal or generalized; episodes vary in duration and frequency1,10|
|Symptoms may linger after an attack resolves (ie, clumsiness, extreme fatigue, weakness, palpitations, and pain)1,12|
|As they age, some patients may experience permanent muscle weakness, further impacting their quality of life over time2|
Strongbridge Biopharma sponsored an educational segment about Primary Periodic Paralysis on The Balancing Act, “Behind the Mystery: Rare and Genetic Diseases.” The segment features Linda Feld, Vice President of Periodic Paralysis Association (PPA), and Steve Cannon, MD, PhD, neurologist and professor of physiology at UCLA. A broad range of topics related to Primary Periodic Paralysis are addressed within the segment, including symptoms, triggers, misdiagnosis, and genetic testing.
