Generally, migraines have a pattern. Migraine attacks go through 4 different stages. However, some people may not experience all the four stages.

- Loss of appetite
- Mood swings from depression to ecstatic
- Frequent urination
- Increased thirst
- Stiff neck
- Sensitivity to light and sound
- The next stage is called Aura which are symptoms of the nervous system. During this stage, you may feel as if someone is touching you, or feel your muscles grow weak. You may also experience motor ( movement ) or speech disturbances. Aura symptoms may appear 5 – 20 minutes before a migraine and build up to last from 30 – 60 minutes.
