  • febrile illness
  • diabetes insipidus (this is not diabetes mellitus)
  • Hyperthyroidism 
  • Pheochromocytoma (secretion from usually benign cells in the brain that produces excessive sweating as one of its symtoms)
  • Hypothalamic lesions in the brain
  • Epilespy
  • Cerebral and brain stem strokes
  • Cerebral palsy
  • Chronic paroxysmal hemicrania (sudden onset migrane)
  • Spinal cord infarction (sudden insufficiency in blood supply)
  • Head injury
  • Familial dysautomia (a congenital syndrome with specific disturbances of the nervous system)
  • Can occur in pregnancy and can be produced by antipyretic medications (anti-nausea)
