What causes migraine without aura?

Scientists are not sure what exactly causes migraines, but believe that they are caused by a combination of factors:  

  • A wave of nerve cell activity spreads across the brain and excites the trigeminal nerve. This excitement leads to the release of neurotransmitters or brain chemicals, such as serotonin, calcitonin gene-related peptide, and dopamine, that trigger a change in the size of blood vessels, releasing more neurotransmitters and causing an inflammatory process
  • Migraines often run in families, suggesting a genetic component.
  • Changes in estrogen levels, such as during menopause, menstrual cycles, and pregnancy, can lead to migraines for some people.
