Myopathies Associated With Systemic Diseases

Abstract

Most of the myopathies associated with systemic diseases respond to treatment of the associated disease or of the myopathy itself. Among the many diseases associated with myopathies are peripheral vascular or collagen- vascular disease, chronic alcoholism, the periodic paralyses, and endocrine disorders. Myopathies associated with systemic diseases plus some other disorders that appear similar are reviewed under the three general headings of those associated with muscle pain, with episodic weakness, and with prolonged weakness.
