BACKGROUND: The distinction between a pre-existing primary headache and a secondary headache at the onset of a disorder is important and has not been taken into account in the International Classification of Headache Disorders-3. This study aimed to improve the general diagnostic criteria for secondary headaches using results of our previous studies.
MATERIALS AND METHODS: We analyzed characteristics of headaches including their changes in intensity, duration, frequency, localization and side, development of new accompanying symptoms, and therapeutic response at the onset of transient ischemic attacks (TIA) (n = 120, mean age 56.1, 55% females) and ischemic stroke (n = 550, mean age 63.1, 56% females) compared to the control group (n = 192, mean age 58.7, 64% females).
RESULTS: Headache of a new type occurred in 8.4% of ischemic stroke patients and 5% of TIA patients on the day of admission but did not occur at all in the control group. Pre-existing headache with a change of at least one characteristic occurred significantly more often in stroke (5.4%) and TIA (7.5%) than in the control group (1%) (p = 0.01 and p = 0.003 respectively).
CONCLUSION: The presence of a new type of headache and a pre-existing headache with altered characteristics in close temporal relation to a disorder indicates causality. Based on these data we propose revised general diagnostic criteria for secondary headaches.
