Area of Science:

  • Neurology
  • Myology
  • Clinical Medicine

Context:

  • Muscle diseases present with varied clinical manifestations, often underestimated.
  • Symptoms range from proximal and distal limb weakness to oculomotor, bulbar, facial, respiratory, paraspinal, and myocardial involvement.

Purpose:

  • To highlight the diverse clinical presentations of muscle diseases.
  • To emphasize the importance of recognizing less common symptoms and early indicators.
  • To outline diagnostic approaches for myopathies.

Summary:

  • Muscle diseases exhibit a wide spectrum of symptoms, including limb weakness, organ involvement, and specific conditions like neonatal hypotonia, hypertrophy, stiffness, paralytic episodes, fatigability, myalgia, rhabdomyolysis, and elevated creatine kinase.
  • Diagnostic tools include biological and electrophysiological tests, with muscle biopsy being central.
  • Muscle imaging and NMR spectroscopy offer further insights into lesion mapping and in vivo muscle metabolism.

Impact:

  • Improved recognition of muscle diseases, leading to earlier diagnosis and intervention.
  • Enhanced understanding of the diagnostic utility of various investigations.
  • Potential for improved patient outcomes through timely and accurate diagnosis.
