Our aims were to investigate the frequency of intracranial lesions detected by cranial computed tomography (CT‐scan) amongst adult patients who had clinical warning criteria (CWC) for secondary neurological headaches and to determine the importance of CWC in predicting a possible lesion on CT‐scan. Seventy consecutive patients with headache exhibiting CWC were included in this prospective study. The CWC included: (i) increase in the intensity and frequency of headache; (ii) abrupt onset of headache; (iii) persistence of headache despite analgesics; (iv) alteration of the characteristics of headache; and (v) presence of focal neurological symptoms or findings. The mean age of the patients was 46.5 years; the female‐to‐male ratio was 1.5. Of the patients, 35.7% had a neurological cause identified by CT‐scan, and 64.3% had normal CT‐scan. In the patients without lesion, of headaches, 64.4% were primary, and 35.6% were from undefined headache group. Although, of the above criteria, only the 5th was different markedly in the patients with lesion than the patients without lesion, in evaluation by CT‐scan the secondary neurological headaches in adults, all CWC should look for absolutely in their history and physical examination.
