Migraine without aura is the most common form of migraine. An estimated 80 to 85% of all migraine sufferers suffer from this type of migraine.

Course and symptoms:
In addition to the severe headache attacks, there are often other accompanying migraine symptoms such as nausea and vomiting as well as sensitivity to light and/or noise.
-
Duration of migraine:
According to the International Headache Classification (ICHD-3 beta), the duration of migraine headaches without aura is between 4 and 72 hours.
-
Pain characteristics:
In most cases, those affected report a one-sided headache, which is described as pulsating and with moderate to severe intensity.
-
Frequency:
The frequency of migraine attacks without aura varies from patient to patient. While some are only affected twice a year, others experience multiple episodes per month. At least five attacks should occur per month. If there are fewer attacks per month, a diagnosis of “probable migraine without aura” can also be made according to ICHD-3 beta. If the attacks occur more than 15 times a month, it is called chronic migraine.

A few days or hours before a migraine attack, signs such as irritability, increased cravings for sweets, fatigue, frequent yawning, restlessness or nervousness may occur.
