Autoimmune acquired autonomic encephalomyelitis

Last edited: 4/22/2026

Overview

Autoimmune acquired autonomic encephalomyelitis involves immune-mediated damage to autonomic nervous system structures, leading to complex autonomic dysfunction including severe hypertension, episodic hypotension, and autonomic neuropathy. 1

Diagnosis

  • Clinical Presentation: Severe hypertension, recurrent migraine-induced hypotension, and episodic vasomotor paralysis.
  • Pathologic Findings: Postmortem evidence of autonomic ganglionitis and neuritis.
  • Recommended Tests: Histopathological examination and immunohistochemical studies of affected tissues.
  • Grading: No specific grading system mentioned; diagnosis relies heavily on clinical and pathological correlation. 1
  • Management

  • First-Line Treatments: Fluid resuscitation and administration of sympathomimetic agents (e.g., epinephrine) and parasympatholytic agents (e.g., atropine).
  • Adjunctive Treatments: Immunosuppressive therapy (specific drug classes and doses not detailed in the abstract).
  • Monitoring: Continuous hemodynamic monitoring due to unpredictable fluctuations in blood pressure. 1
  • Special Populations

  • Pregnancy: Not addressed in the provided abstracts.
  • Pediatrics: Not addressed in the provided abstracts.
  • Elderly: Not addressed in the provided abstracts.
  • Comorbidities: Management complexity increases with comorbidities; specific guidance not provided. 1
  • Key Recommendations

  • Prompt initiation of fluid resuscitation and vasopressor support in cases of severe hypotension. (Evidence: Weak) 1
  • Consider histopathological examination for definitive diagnosis, particularly in fatal cases. (Evidence: Weak) 1
  • Immunosuppressive therapy should be considered based on underlying autoimmune etiology, though specific protocols are not detailed. (Evidence: Expert opinion) 1
