Abstract
We examined the representativeness of baseline headache diary recording periods of 1, 2, 3, and 4 weeks for three kinds of headache disorder — tension, migraine, and combined migraine and tension. For research purposes at pretreatment, 2 weeks of diary recording are preferable for tension headache, while at least 3 weeks are preferred for migraine and combined headache. At follow-up, 1 week of diary recording appears adequate for all three headache types. Recommendations are also made for clinical practice.
