a year). The other main pattern of cluster headache is termed “chronic” (and is also known as chronic migrainous neuralgia). It may come out of the blue or emerge several years after an episodic pattern. It is characterized by the absence of sustained periods of remission. The episodic and acute forms of cluster headache may transform into the other, so it is clear that they are merely different-appearing patterns of one and the same disease.

Formerly known as hyaline membrane disease, a syndrome of respiratory difficulty in newborn infants caused by a deficiency of a molecule called surfactant.
