Research topic:~Weekend headaches in school-age children~Scientific background:~Headache is one of the most common complaints in children and adolescents. It is recognized as one of the top medical and neurologic contributors to the global burden of disease and is a leading cause of disability in adolescents and young adults [1].~Recurrent severe headaches also are common in children. In the United States, approximately 20 percent of children aged 4 to 18 years report having had notable recurrent headaches in the past 12 months and the prevalence increases with age [2].~The International Classification of Headache Disorders, 3rd edition (ICHD-3) provides detailed diagnostic criteria for primary headaches which include mainly migraine and tension-type headache [3].~A diary in which the quality, location, severity, timing, precipitating and palliating factors, and associated features of the headache are recorded prospectively (not subject to recall error) may be a useful adjunct if the child is willing and able to complete daily [4].~There are many triggers for headaches including academic or emotional stress, lack of sleep, or lack of exercise, multiple screen hours, untidy meals, change in consumption of caffein, alcohol or energy drinks, etc. It can be assumed that the presence of these triggers varies between weekends and routine days at school and thus affects the incidence of headache [5-8].~There are few studies that investigated weekend headaches among the adult population [9-11], and only two studies which mentioned differences in headache between days of the week among school [12, 13]. Mehta [12] reported the rate of headaches in weekends to be 5.9% compared to 28.5% on monday, among children age 7-14 years of age. However they didn't report on the incidence of other weekdays headaches. On the other hand, Larsson et al [13] didn't find significant difference in headache incidence between weekdays and weekends, although the peak incidence was at the middle of at Thursday.~Finally, learning disabilities and ADHD are more common in children and adolescents who suffer from primary headaches [14], and because much of the headache in children is attributed to school, it will be interesting to see the effect of this group on the distribution of headache throughout the week.~Purpose of the study:~Our goal is to investigate whether there is weekend headache in children and adolescents and what are the risk factors.~Methods:~This is an observational prospective follow-up study. The study population will include 30 children aged 6-18 years who suffer from a primary headache and are treated at the Pediatric Neurology Clinic at Bnai Zion Hospital in Haifa, Israel.~After the adolescents or parents sign an informed consent to participate in the study, they will receive a headache diary (Appendix 1) which they will fill out for 4 weeks as recommended [15]. They will mark the day the headache appeared, its intensity, duration, and timing during the day. In addition, they will fill the various triggers offered (such as sleep hours, exercise time, screen hours, and a subjective sense of academic or emotional stress) on days with headache and on every weekend.~We will then divide the participants into two groups - those who suffer from a headache in the middle of the week only (MWH) and those who suffer from a headache at the weekend (WH), compare the demographic and clinical characteristics and we will try to understand the triggers of these two groups.~Patients will also be asked a questionnaire which will define whether they are having difficulty in school (Appendix 2) so that we can examine the distribution of headaches of this group during the week.~A physician who works on the research team will proactively verify that the questionnaire is filled out consistently and accurately. Additional data will be collected from the medical record.~The study will be conducted after receiving approval from the Institutional Helsinki Committee~Statistical analysis:~The data will be processed and analyzed using SPSS software. Two sample t-test will be performed for continuous variables, and X² for categorial data. Odds ratios with 95% confidence intervals will be computed, statistical significance is considered as p <0.05.~Tables and graphs:~Appendix 1- Headache diary (לצרף Appendix 2- Questionnaire to diagnose suspected difficulty in studies (לצרף?
