Autonomic Nervous System Effects

WHY THE SYMPATHETIC IS OVERACTIVE IN ARACHNOIDITIS:

The central nervous system is damaged in arachnoiditis. It is therefore unsurprising that it may not function normally.

Some possible factors might be:

  • Abnormal feedback from damaged nerves
  • Thalamic effects: pain, stress
  • Limbic system: emotional input?
  • Sympathetic chain:? direct damage
  • Spinal cord injury>> autonomic dysfunction
  • Cervical pathology >> autonomic dysreflexia
  • Thyroid abnormalities
  • Effects of medication?
  • Disturbance of hypothalamic-pituitary axis (seen in some fibromyalgia patients)

Constant pain is a continual stressor, resulting in adrenal over activity and subsequent exhaustion (sudden onset fatigue may be associated)
