	abstract = "With a high economic, social, and personal burden, headache remains an important health problem. How UK GPs diagnose headache in the UK is unknown. In this study, a large primary care database was used and diagnostic categories were described for 91 121 adult patients with new-onset headache, that is, patients who had not consulted for headache in the previous year. Seventy per cent of headaches were not given a diagnostic label, 24% were diagnosed as primary, and 6% as secondary headaches. It is suggested that GPs' difficulty in diagnosing headache presentations contributes to the high level of morbidity and unmet need in this disease.",
