Prognosis of migraine and tension-type headache: a population-based follow-up study.
OBJECTIVE
To determine the prognosis of migraine and tension-type headache and to identify prognostic factors.


METHODS
Of 740 persons (aged 25 to 64 years) examined in a 1989 Danish cross-sectional headache study, 673 were eligible for follow-up in 2001. All interviews at baseline and at follow-up were conducted by medical doctors and based on the 1988 IHS-criteria.


RESULTS
A total of 549 persons (81.6%) participated in the follow-up study. Of 64 migraineurs at baseline, 42% had experienced remission, 38% had low migraine frequency, and 20% had more than 14 migraine days per year (poor outcome) at follow-up. Poor outcome was associated with high migraine frequency at baseline and age at onset younger than 20 years. Among 146 subjects with frequent episodic tension-type headache and 15 with chronic tension-type headache at baseline, 45% experienced infrequent or no tension-type headache (remission), 39% had frequent episodic tension-type headache, and 16% experienced chronic tension-type headache (poor outcome) at follow-up. Poor outcome was associated with baseline chronic tension-type headache, coexisting migraine, not being married, and sleeping problems.


CONCLUSIONS
The prognosis of migraine, frequent episodic tension-type headache, and chronic tension-type headache was favorable.
