[Temporal nosography of primary headache]

The lack of certain etiopathogenetic elements and the numerous clinical-descriptive classifications of primary headaches has brought the research-workers to elaborate a chrono-pathological classification of pain in the primary headaches. So, they present a chrono-nosography and they suggest that the continuous form of primary headaches can be divided into two forms, one of these is associated with affective troubles. Then they emphasize the problem of classic migraine and its clinical variant as a trigger of vascular disease.
