Area of Science:

  • Neurology
  • Autonomic Neuroscience

Background:

  • Acute pandysautonomic neuropathy presents with significant postganglionic sympathetic and parasympathetic dysfunction.
  • This condition typically spares motor and sensory nerve functions.

Observation:

  • Previous sural nerve biopsies in similar cases showed variable results, with some normal and others revealing fiber loss.
  • This study details a patient with pandysautonomic neuropathy and elevated cerebrospinal fluid protein.

Findings:

  • The patient's sural nerve biopsy demonstrated active axonal degeneration.
  • This finding contributes to understanding the pathological changes in acute pandysautonomic neuropathy.

Implications:

  • Highlights the potential for active axonal degeneration in pandysautonomic neuropathy.
