Larsson B, et al. - Researchers used previously assessed data at the baseline and 1-year follow-up data of early adolescents to determine factors that predict the progression, frequency, and outcome of frequent headaches (at least once a week) over the long term (14 years). The original sample comprised 2,440 participants in the first two assessments; of these, 1,266 participants (51.9% response rate) aged 26–28 years (mean = 27.2 years) completed an electronic questionnaire with questions about headache frequency and duration at the long-term follow-up. As per findings, important indicators for both short- and long-term prognosis of frequent headaches include gender, greater social impairment, and comorbid depressive symptoms.
