hyperkalemic periodic p. a form of periodic p. in which the serum potassium level is elevated during attacks; onset occurs in infancy, attacks are frequent but relatively mild, and myotonia is often present; autosomal dominant inheritance.
hypokalemic periodic p. [type I MIM 17066, *170600, *311700] a form of periodic p. in which the serum potassium level is low during attacks; onset usually occurs between the ages of 7 and 21 years; attacks may be precipitated by exposure to cold, high carbohydrate meal, or alcohol, may last hours to days, and may cause respiratory p.; autosomal dominant or X-linked inheritance.
hysterical p. a psychosomatic numbness of a limb sometimes to the point of p. See hysteria.
immune p. the induction of tolerance in mice due to injection of large amounts of polysaccharide. The polysaccharide is poorly metabolized and the p. remains only during the persistence of the above.

mixed p. combined motor and sensory p.
motor p. loss of the power of muscular contraction.
musculospiral p. p. of the muscles of the forearm due to injury of the radial (musculospiral) nerve.
myogenic p. acute anterior poliomyelitis
normokalemic periodic p. [type III MIM 170600] a form of periodic p. in which the serum potassium level is within normal limits during attacks; onset usually occurs between the ages of 2 and 5 years; there is often severe quadriplegia, usually improved by the administration of sodium salts; autosomal dominant inheritance.sodium-responsive periodic p;
obstetrical p. obstetrical palsy
ocular p. p. of extraocular and intraocular muscles.
parturient p. milk fever (2)
periodic p. term for a group of diseases characterized by recurring episodes of muscular weakness or flaccid p. without loss of consciousness, speech, or sensation; attacks begin when the patient is at rest, and there is apparent good health between attacks. See hyperkalemic periodic p., hypokalemic periodic p., normokalemic periodic p.
