Prospective and retrospective studies showed that headaches (migraine and tension-type) with childhood or adolescent onset have age-related characteristics and change over time, with high rate of type changing, remission or improvement. The reasons are unknown. On the other hand, several studies focused on factors that may be precursors of childhood headaches. All these factors may allow a developmental arc to be outlined, defining the natural history of headache from birth to adulthood. Familial (genetic?) influence, hyperreactivity, periodic syndromes and anxiety in childhood are factors that may predict headache onset, against the background of developmental modulation of pain. Biological and psychological factors are probably reciprocally involved, although the link is unclear. The identification of prognostic factors could allow a better framing of headaches and, from an integrated perspective, have important implications as regards clarifying the "nature" of headache.

Headache is one of the most common neurological symptom reported in childhood and adolescence, leading to high levels of school absences and being associated with several comorbid conditions, particularly in neurological, psychiatric and cardiovascular systems. Neurological and psychiatric disorders, that are associated with migraine, are mainly depression, anxiety disorders, epilepsy and sleep disorders, ADHD and Tourette syndrome. It also has been shown an association with atopic disease and cardiovascular disease, especially ischemic stroke and patent foramen ovale (PFO).

Objective The present Italian multicenter study aimed at investigating whether the course of primary headache disorders in children and adolescents was changed during the lockdown necessary to contain the COVID-19 emergency in Italy. Methods During the lockdown, we submitted an online questionnaire to patients already diagnosed with primary headache disorders. Questions explored the course of headache, daily habits, psychological factors related to COVID-19, general mood and school stress. Answers were transformed into data for statistical analysis. Through a bivariate analysis, the main variables affecting the subjective trend of headache, and intensity and frequency of the attacks were selected. The significant variables were then used for the multivariate analysis. Results We collected the answers of 707 patients. In the multivariate analysis, we found that reduction of school effort and anxiety was the main factor explaining the improvement in the subjective trend of headache and the intensity and frequency of the attacks ( p 0.05), presence of chronic headache disorders ( p > 0.05) and geographical area ( p > 0.05). Conclusions Our study showed that lifestyle modification represents the main factor impacting the course of primary headache disorders in children and adolescents. In particular, reduction in school-related stress during the lockdown was the main factor explaining the general headache improvement in our population.

Aim: The purpose of this study was to evaluate both the effects of ibuprofen and/or acetaminophen for the acute treatment of primary migraine in children in or out prophylactic treatment with magnesium. Methods: The study had been approved by the Researchers Ethics Committee of the “Pugliese-Ciaccio” Hospital (protocol number 720/2010; EUDRACT NUMBER 2012-005737-36) and the children ranging from the ages of 5 to 18 years with at least four attack/month of primary migraine were enrolled. A Visual Analogical Scale was used to evaluate pain intensity at the moment of admission to the study (start of the study) and every month up to 18 months later (end of the study). Results: 160 children of both sexes were assigned in four groups to receive a treatment with acetaminophen or ibuprofen without or with magnesium. Migraine pain endurance and monthly frequency were similar in the four groups. Both acetaminophen and ibuprofen induced a significant decrease in pain intensity (p

Background: Headache and sleep are related in different ways and alterations of chronobiological mechanisms are involved in headache. We investigated the relationships between headache and sleep quality in a large non-clinical population of children and adolescents and evaluated the relationship between headache and circadian typologies. Methods: A total of 1073 children and adolescents (50.9% males; mean age=10.56; range=8−15 years) were recruited from four schools in Rome. They filled out the questionnaires individually in classrooms, after brief group instruction about answer formats. The questionnaires included (a) a self-report headache questionnaire to collect information on different aspects of headache attacks based on the International Classification of Headache Disorders-2nd edition (ICHD-2); (b) the School Sleep Habits Survey that incorporated questions about sleep habits, the Sleep–Wake Problems Behaviour Scale (SWPBS), the Sleepiness Scale (SLS) and the Morningness/Eveningness Questionnaire (MEQ). Results: According to ICHD-2 criteria, we classified 70 (6.5%) children as Migraine Group (MG), 135 (12.7%) as Non-Migraine Headache Group (NMG), and the remaining 868 (80.8%) were classified as Headache-Free Group (HFG). No clear differences have been found between MG and NMG regarding the frequency of the attacks, although MG showed a significantly increased frequency of long-lasting attacks. The modality of onset of pain and the location of pain was similar in both groups. The most frequent triggering factor for headache in MG and NMG was "a bad sleep" (32.2%) followed by emotional distress (27.8%). No differences have been found between MG, NMG and HFG in sleep schedule or sleep duration. MG and NMG showed significantly higher scores on the SWPBS vs. HFG, while MG presented higher scores on the SLS compared to NMG and HFG. MG presented lower MEQ scores, indicating a more pronounced eveningness. Conclusions: The relationships between headache and sleep problems are evident even in a non-clinical population of children and adolescents, with MG showing poorer sleep quality, sleepiness and a tendency toward eveningness.

Several epidemiological studies have shown the presence of comorbidity between various types of sleep disorders and different headache subtypes. Migraine without aura is a sensitive risk factor for disorders of initiating and maintaining sleep (odds ratio (OR) 8.2500), and chronic tension–type headache for sleep breathing disorders (OR 15.231), but headache disorder is a cumulative risk factor for disorders of excessive somnolence (OR 15.061). This result has not been reported in the clinical literature.

The aim of the study was to evaluate sleep of children with migraine during the interictal period and the modifications of sleep which precede, are concomitant with, or follow migraine attacks. Eighteen patients with migraine without aura were compared with a group of 17 healthy age-matched children. Sleep parameters were monitored for two full weeks by means of actigraphs and self-report diaries. Headache diaries were also filled out in order to evaluate the occurrence and the characteristics of migraine attacks. Fifty-seven attacks were recorded during the monitoring period. During the interictal period, sleep parameters of children suffering from migraine did not differ from those of controls; only sleep onset latency was slightly prolonged in the migraine group. Timing of the attack affected nocturnal motor activity which presented the lowest values on the night preceding the attack, indicating a decrease in cortical activation during sleep preceding migraine attacks. Further studies should clarify if the observed reduction in nocturnal motor activity close to the attack is related to neurotransmitter imbalance.

Chronic daily headache (CDH) represents a challenge in clinical practice and the scientific field. CDH with onset in children and adolescents represent a matchless opportunity to understand mechanisms involved in adult CDH. The aim of this study was to evaluate the diagnosis, prognosis and psychiatric co-morbidity of CDH with young onset in the young. Fifty-nine CDH patients has been followed from 1997 to 2001 in our department. Headache and psychiatric diagnoses were made on the basis of the international system of classification (International Headache Society, 1988; DSM-IV). X2 test and multinomial logistic regressions were applied to analyse factors predicting outcome. The current diagnostic system allows a diagnosis in 80% of CDH patients, even if age-related characteristics have been evidenced. Psychiatric disorders are notable in CDH (about 64% of patients) and predict (mainly anxiety) a poorer outcome. Surprisingly, analgesic overuse is not involved in the chronicization process. Diagnosis of CDH needs further study. Psychiatric disorders predict a worse outcome and greater account should be taken of them in treatment planning.
