It is assumed that lifestyle and environmental factors have an important role among the causes that trigger migraines.

As for the aura, specialists tend to blame a spread cortical depression, consisting of a wave induced by nerve cells that spread in a wide area of the cortex and is considered the first phase, known as hyperexcitability, process, during which the area needs a large amount of blood, which is followed by another phase, called inhibition, in which neurons maintain a state of rest, and then in the same area, in this case, it should be much less blood than before.
