  • Bad body posture (causes compression of important arteries and/or nerves) [xxx]
  • Brain injury
  • Degenerative neurological diseases such as Parkinson’s disease
  • Exposure to chemicals (e.g., most commonly, pyridoxine)
  • Genetic factors
  • Hereditary connective tissue diseases, especially Ehlers-Danlos Syndrome
  • Pregnancy
  • Physical trauma or injury which damages the autonomic nervous system, as with Cerebral salt-wasting syndrome.
