Orthostatic intolerance and autonomic disorders are increasingly recognized, necessitating a reclassification of related syndromes. This review details their pathophysiology, classification, and treatment approaches.

Area of Science:

  • Neurology
  • Cardiology
  • Autonomic Nervous System Research

Context:

  • Growing clinical interest in orthostatic intolerance and autonomic disorders.
  • Recognition of distinct clinical entities with overlapping features.
  • Need for reclassification of previously unrecognized syndromes.

Purpose:

  • To review the pathophysiology and classification of autonomic dysfunction syndromes associated with orthostatic intolerance.
  • To present primary and secondary causes of dysautonomia.
  • To outline therapeutic approaches for these syndromes.

Summary:

  • Orthostatic intolerance is linked to autonomic disorders, presenting with syncope, near syncope, chronic fatigue, and vasodepressor reactions.
  • Understanding pathophysiology has led to recognizing distinct syndromes requiring reclassification.
