About one third of migraine patients has symptoms which announce the attack up to 2 days before the actual migraine attack. These precursors can be very different:
– appetite for sweets
– frequent yawning
– hyper activeness
– fatigue and much much
If the migraine attack follows, the patient easily sees the precursors as the trigger of the cause of the migraine – for example stress for the precursor testiness, chocolate for the appetite for sweets or little sleep for fatigue. However, this would be a misconception. These are not even trigger of a migraine attack and especially not a cause. Rather, these are the first unspecific symptoms of a migraine attack.
