Scope note: Trastorno familiar autosómico dominante que se presenta en el lactante o durante la infancia y se caracteriza por episodios de debilidad asociada con hiperpotasemia. Durante los ataques, se afectan inicialmente los músculos de las extremidades inferiores, seguidos por los de la porción inferior del tronco y los brazos. Los episodios duran de 15-60 minutos y ocurren típicamente tras un período de reposo después del ejercicio. Se ha identificado un defecto en los canales de sodio del músculo esquelético como la causa de esta afección. La parálisis periódica normopotasémica es una enfermedad íntimamente relacionada que se caracteriza por ausencia de alteraciones de las concentraciones de potasio durante los ataques de debilidad.

Scope note: An autosomal dominant familial disorder which presents in infancy or childhood and is characterized by episodes of weakness associated with hyperkalemia. During attacks, muscles of the lower extremities are initially affected, followed by the lower trunk and arms. Episodes last from 15-60 minutes and typically occur after a period of rest following exercise. A defect in skeletal muscle sodium channels has been identified as the cause of this condition. Normokalemic periodic paralysis is a closely related disorder marked by a lack of alterations in potassium levels during attacks of weakness. (Adams et al., Principles of Neurology, 6th ed, p1481)
