Area of Science:

  • Neurology
  • Genetics
  • Molecular Biology

Background:

  • Primary periodic paralyses (PPs) are rare hereditary muscle disorders.
  • Characterized by episodic flaccid muscle weakness and sometimes myotonia.
  • Distinct from more common secondary (acquired) forms.

Purpose of the Study:

  • To comprehensively review current knowledge on primary periodic paralyses (PPs).
  • To discuss recent advances in understanding PPs.
  • To consolidate information on etiology, genetics, pathogenesis, diagnosis, and treatment.

Main Methods:

  • Literature review of primary periodic paralyses.
  • Synthesis of current research on molecular genetics and genotype-phenotype correlations.
  • Discussion of diagnostic and therapeutic strategies.

Main Results:

  • PPs stem from mutations in skeletal muscle ion channel genes (sodium, potassium, calcium).
  • Includes conditions like hyperkalemic PP, hypokalemic PP, and Andersen's syndrome.
  • Triggers include exercise, cold, diet, stress, and certain medications.

Conclusions:

  • This review consolidates current knowledge on primary PPs.
  • Highlights advances in understanding the molecular basis and clinical manifestations.
  • Provides insights into diagnosis and management of these rare disorders.
