    Introduction Primary headaches are closely related to sleep. Great modifications in the arousal patterns during sleep have been reported in migraine, especially in the nights preceding a headache attack. Aim of the study was to evaluate the pattern of arousal from sleep in a group of migraine school-aged patients. Materials and methods Population study consisted of 5 patients, (four females and one male), aged 8-15 years (mean 11.7 years, SD±2.43), affected by migraine without aura (MO), according to ICHD-II criteria, who referred to the third University Level Headache Centre for Developmental Age of the Department of Child and Adolescent Neuropsychiatry of the Second University of Naples. All the mothers of the subjects were asked to fill in the Sleep Disturbances Scale for Children (SDSC) questionnaire to assess the presence of sleep troubles. Patients underwent three overnight polysomnographic studies, following adaptation; arousal pattern was studied by the scoring of the cyclic alternating pattern (CAP). Results Migraineurs showed a lower CAP rate in non-rapid eye movement (NREM) sleep (CAP rate mean value 14.875% vs. 24.56% of matched control, p=0.005) and, in particular, a lower number of A1 phases, as shown in a recent report in an adult population. The reduction in the CAP rate indicates a lower level of arousal fluctuation in NREM sleep, suggesting a dysfunction in neural structures involved in both the control of REM sleep and the pathophysiology of migraine, such as the hypothalamus and the brainstem. Discussion In the last 30 years, the intimate relationship between sleep and headache has been recognized even if the relationship remains clinically and nosologically complex, and widely obscure. Headaches associated with nocturnal sleep have often been perceived as either the cause or result of disrupted sleep. Recent biochemical and neurofunctional imaging studies in patients with primary headache disorders has lead to the identification of potential central generators which are also important for the regulation of normal sleep architecture and sleep microstructure and could be an important tool to clarify the relation between the two. Conclusions The relationship between headaches and sleep disturbances is complex and difficult to analyse, but neurophysiological tools and sleep study (both macrostructural and microstructural) could be useful to clarify this obscure aspect of two so frequent clinical events, particularly in school-aged children

    Background. La letteratura sulla relazione tra coordinazione motoria e modalità di sonno in età evolutiva è scarsa. Scopo del presente studio è esplorare le relazioni esistenti tra l’organizzazione macrostrutturale del sonno e le capacità di coordinazione motoria in età evolutiva in un gruppo di bambini affetti da DCD. Metodi. 121 bambini (75 M, età media10,03 ± 2,76) sono stati sottoposti al test Movement Assessment Battery for Children (M-ABC), Beery-Buktenika Visual-Motor Integration test (VMI) ed a polisonnografia notturna (PSG), in seguito è stato individuato un gruppo di soggetti affetti da DCD composto da 42 bambini (26 M, età media10,12 ± 1,98) ed un gruppo di 79 soggetti non affetti (49 M, età media 9,94 ± 2,84) confrontati mediante t-test sui dati macrostrutturali del sonno. Risultati. Dall’analisi di correlazione sono emerse relazioni significative tra abilità motorie e parametri di durata del sonno oltrechè quelli di rappresentazione percentuale degli stadi con particolare riferimento al sonno REM. Inoltre i soggetti con DCD presentano una riduzione media di tutti i parametri di durata del sonno e della quota di REM% rispetto ai controlli. Conclusioni. Il presente studio dimostra come coordinazione motoria e integrazione visuo-motoria siano strettamente legate alle modalità macrostrutturali del sonno, tali risultati potrebbero porsi come punto di partenza per ulteriori e più approfonditi studi sul legame tra modalità di sonno notturno e capacità motorie superiori

    HEADACHE AND SLEEP DISORDERS IN CHILDHOOD

    Clinical observations supported by experimental data suggest that sleep and headache share common anatomical, physiological and biochemical substrates, as shown by the possibility of coexisting also in the same patient of headache and sleep disorders and by their relative frequency in the general population and in children. Sleep represents the only well-documented behavioural state related to the occurrence of some headache syndromes while headache may cause various degrees of sleep disruption and seems to be associated with several sleep disturbances either in adults or in children. Children with migraine headaches appear to have a range of sleep disturbances: insufficient sleep, bruxism, and maternal co-sleeping are significantly more frequent compared to children from a normative community sample. Children with migraine experienced greater sleep disturbances in all domains including longer sleep onset delay, more bedtime resistance, shorter sleep duration, more daytime sleepiness, more night wakings, greater sleep anxiety, more parasomnias, and more sleep-disordered breathing. Even though several studies demonstrated a high prevalence of sleep disorders in headache subjects, sleep disorders are not seen as a comorbid or causative factor for headache. While patients complain about their sleep disorders, these manifestations are usually considered as “common insomnia” of psychological origin and tend to be considered not relevant by physicians. Early sleep disorders have been also related to psychiatric co-morbidity and involved in the endurance of headache in children and adolescence; in an 8-year follow-up study it has been found that the most frequent comorbid disorders at the onset of the headache were sleep disorders (12%) followed by anxiety (11%); of the 9 patients with sleep disorders as comorbid factor at the onset of headache, at follow-up 6 had enduring headache and 3 were headache-free
