Current pain and headache reports
-
Migraine and cluster headache have been considered entirely separate clinical syndromes, both in routine clinical practice and in the 1988 International Headache Society classification. Neurologists seeing large numbers of patients soon realize, however, that there is a considerable overlap between the two conditions. ⋯ In addition, it is not uncommon for a patient with a lifetime's history of migraine to experience a typical bout of cluster headache, although the reverse is less common. This article reviews the published series of such patients.

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. ⋯ 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.
