Sub-division of headache stage in a whole migraine attack
Objective: To reveal the inter-relationship during the headache stage of migraine attack for the purpose of improving the recent recognize of regularities during migraine attack. Background: Migraine is a neurovascular headache with recurrent attack. Recently: a complete migraine attack is generally divided into four stages: prodromal, aura, headache and recovery stages. There still are some neurologists to divide it into five stages: prodromal, aura, headache, recovery and postdromal stages. After detailed observation andstudy among 530 migraineurs in .clinical practice, the author found the former divisions do not stress more efforts in different extent on regular varieties” of the headache stage, and only give an indistinct boundary---headache stage. The author believes that there is an important significance to reveal the regular varieties of headache during headache stage and the relationship between their varieties for deepening our comprehension of a complete migraine attack, and meanwhile, benefiting us to select proper therapies and acquirinig a appropriate estimation for them. Methods: 530 cases with migraine were inquired during their treatment in my special migraine clinic from 1993 to 1996. The inquiry was exerted by patients” recountal about their a complete migraine attack from beginning to ending, containing intensity of head pain and its duration, supplemented by their relatives if necessary. And then, the duration was regarded as abscissa and the intensity of head pain as ordinate and a curve was drawn in the coordinate based on these information including duration of headache fi.om mild to severe( ascending phase ), duration of severe headache ( platform phase ) and duration of headache from severe to ending (descending phase) Results: Among 530 cases, there were 483 cases with a complete course of ascending, platform and descending phases during headache stage; 17 cases without ascending phase or not obvious; 30 cases without descending phase or not obvious; all cases with platform phase. Among 483 cases with a complete course of ascending, platform and descending phases, the average duration of ascending phase was 3.615 hours ( the shortest, 10 minutes; the longest, 24 hours. ); of platform phase, 9.096 hours ( the shortest, ” hour; the longest, 36 hours ); of descending phase, 6.154 hours ( the shortest, 15 minutes; the longest, 48 hours.). See Table ) l iscussion: 1, Platform phase of headache stage and judgement of headache intensity in migraine. 2, Relationship between phases of headache stage and choice of period of treatment and its therapeutic results Conclusion: There are some regular varieties during the headache stage of a complete migraine attack, and a proper sub division of this stage will help us to dee pen the comprehension of the headache stage of a complete migraine attack and to quantify the headache intensity of migraine as well as therapeutic results. Meanwhile, it is also helpful for us to make choice of opportunity for treatment of migraine and understand relationship between the phases and their therapeutic results.
