Q

Where does the pain in the brain come from?

A
  • Cortex and meninges directly cause pain via blood vessels and stimulates the Trigeminal nerve which passes pain to the area of the cerebral cortex for processing
  • Brainstem is center of sensory pain information passing to the brain
  • Brainstem passes signals to cerebral cortex for CSD as well as pain.
  • Genetic: Migraine patients have a abnormal sensory pain processing from trigeminal nerve/brainstem through the Thalamus. Lower threshold to produce migraine headache.
