Reduced appetite, nausea or vomiting are typical accompanying features of a migraine attack. In addition, sensitivity disorders of other sensory organs can occur such as light or noise sensitivity. A hypersensitivity to smells or odors is especially unpleasant. The patients usually lie down in their bed, draw the curtains to eliminate any light and ask for silence. Since migraine is an episodic disorder, at least 5 previous attacks are needed to make a diagnosis. A recurrence of attacks is characteristic of migraine.
