Signs and Symptoms
Migraines typically present with self-limited, recurrent severe headache associated with autonomic symptoms. About 15-30% of people with migraines experience migraines with an aura and those who have migraines with aura also frequently have migraines without aura. The severity of the pain, duration of the headache, and frequency of attacks is variable. A migraine lasting longer than 72 hours is termed status migrainosus. There are four possible phases to a migraine, although not all the phases are necessarily experienced:
- The prodrome, which occurs hours or days before the headache
- The aura, which immediately precedes the headache
- The pain phase, also known as headache phase
- The postdrome, the effects experienced following the end of a migraine attack

On the one hand, there have started into life industrial and scientific forces which no epoch of former human history had ever suspected. On the other hand, there exist symptoms of decay, far surpassing the horrors recorded of the latter times of the Roman empire. In our days everything seems pregnant with its contrary.”
