GARCIA GOMEZ, Carlos; SANCHEZ SANCHEZ, Samuel  e  RUIZ MARTINEZ, Gretel. Hypokalemic periodic paralysis. Presentation of a case. Medisur [online]. 2020, vol.18, n.5, pp. 924-927.  Epub 02-Out-2020. ISSN 1727-897X.

Hypokalemic periodic paralysis is generally caused by autosomal dominant mutations in the voltage-dependent calcium channel gene; seizures of weakness usually persist for hours or days before gradually resolving; the serum potassium level may be low or normal during the crisis. This disorder can present in an acquired way in conditions such as digestive losses of potassium, potassium-depleting diuretics, among others. The case of a 53-year-old white-skinned patient who came to the clinic due to loss of muscle strength in all four limbs, and preserved osteotendinous reflexes it is describe. In the tests, only the low serum potassium values (1.99 mmol / L) stand out. The rare frequency with which this disorder occurs, the form of presentation in this patient, and the probability of confusing it with other diseases, motivated the publication of the article.
