Trigger factors, signs and symptoms of the preheadache phases of episodic tension-type headache (ETTH), typical aura with non-migraine headache (TANMH), migraine with (MA) and without aura (MwA) may show similar features. Our objective was to investigate the preheadache phases and trigger factors of these headache types. Questionnaires including trigger factors, signs and symptoms of preheadache phases were answered by all headache patients. A total of 96 patients, 31 ETTH, nine TANMH, 23 MA and 33 MwA patients were included in this study. Analysis of seven groups consisting of 18 individual trigger factors showed that only two groups and five individual trigger factors were significantly different between groups. Hunger and odour were significantly more common in MA, MwA and TANMH patients. Foods were a significant precipitant factor for headache in MA patients. Head and neck movements were important trigger factors in ETTH. In prodrome phase only one out of three groups differed significantly between headache types. Migraine and TANMH patients reported significantly more general signs and symptoms. Analysis of aura signs and symptoms showed that only two out of six groups were significantly more frequent in MA and TANMH patients. Visual aura symptoms were more frequent in MA and TANMH groups, where sensorial auras were reported to be the most frequent in the MA group. Our results showed that different type of headaches share common prodrome and aura signs and symptoms as well as the same trigger factors. We suggest that similar trigger factors may trigger similar mechanisms and may cause common preheadache signs and symptoms in all headache types.

Age and gender appeared to be demographic factors increasing adolescent headache prevalence. Frequent episodic-tension type headache was the most common headache followed by migraine. Our migraine prevalence was slightly higher than most of the previously reported prevalence rates. This might be due to the new classification criteria of headache released by International Headache Society.

. The sample group was selected from people living in the central district of Bursa, according to the stratified sampling method with regard to socioeconomic class, age, and sex. Neurology residents using standard questionnaires and semistructured interviews carried out faceto-face interviews.Results: Of the 199 presumptive cases detected in the initial interview, 26 (11 female, 15 male subjects) received the diagnosis of epilepsy on the day of assessment. Prevalence of active epilepsy was 8.5 per 1000, and lifetime prevalence was 12.2 per 1000 in the central district of Bursa. Classification of the epileptic seizures revealed that 30.7% of the patients had partial and 65.3% had generalized seizures; seizures could not be classified in 3.8%. The seizures had begun during the first decade of life in 50% of the cases, and 34.6% have been using regular medications.Conclusions: Prevalence studies in our country are scarce; thus further research including different regions and multiple centers is needed. Addition of questions suitable to the Turkish social structure to the standard questions determined by WHO may be beneficial for practitioners in considering the diagnosis of epilepsy and referring these patients to specialized centers.
