Abstract
Cluster headache is one of the most excruciating headaches affecting human beings--especially the male sex. Most of the cluster headache cases are of episodic nature, with active cluster periods lasting generally between a few weeks and 2 or 3 months. A still undetermined percentage of patients report nonpainful sensations preceding the onset of the pain attack for a variable period of time. If occurring only a few minutes or a few hours before the onset of pain, such symptoms are called prodromal. When occurring for several days, weeks, or months before the pain, they are termed premonitory symptoms. The author believes that premonitory symptoms have not been properly diagnosed and emphasizes the need to investigate their presence, because by knowing them advances can be made in the understanding of the physiopathology of this particular cephalalgia. Furthermore, it can also allow the physician to be ahead, by giving preventive treatment and stopping or diminishing the intensity and duration of the pain attacks.
