ReviewEpidemiology of migraine and headache in children and adolescents.
Migraine and headache are global disabling conditions causing considerable individual suffering and impaired quality of life in adults as well as in children and adolescents. Therefore, epidemiological studies are essential to assess the scope of the problem. This review covers epidemiological studies on migraine and headache in children and adolescents published in the past 25 years. ⋯ The estimated overall mean prevalence of headache was 54.4% (95% CI 43.1-65.8) and the overall mean prevalence of migraine was 9.1% (95% CI 7.1-11.1). There is a lack of population-based studies from low and low-middle income countries. In addition, there is very little information about the prevalence of probable migraine and chronic migraine and no information about menstrual migraine in the young.

Several scientific studies report a close relationship between sleep and headache: sleep changes may reflect the onset and increase of both duration and frequency of headache attacks. Variations in sleep architecture, together with a poor sleep hygiene in children, may indeed be responsible for the onset of headache and its development into a chronic disease. For a correct clinical management of children with headache, it is therefore fundamental to investigate their sleep habits, architecture and potential disturbances, in order to develop adequate therapeutic plans for both sleep and headache.

Nummular headache (NH) is a rare headache disorder characterized by focal and well-circumscribed pain fixed within a rounded or oval/elliptical-shaped area of the head, typically 2 to 6 cm in diameter (Grosberg et al. Curr Pain Headache Rep 11:310-2, 2007). The disorder most commonly affects the parietal region and is almost always unilateral and side-locked. ⋯ Rarely, the disorder may be bifocal or multifocal, affecting various regions of the head simultaneously or in sequence. Treatment with gabapentin, tricyclic antidepressants, or botulinum toxin may be helpful. In this review of the more than 250 cases now reported in the literature, the epidemiology, clinical features, pathogenesis, differential diagnosis, and management of this disorder are discussed.

ReviewOptimism and the experience of pain: benefits of seeing the glass as half full.
There is a strong body of literature that lends support to the health-promoting effects of an optimistic personality disposition, observed across various physical and psychological dimensions. In accordance with this evidence base, it has been suggested that optimism may positively influence the course and experience of pain. ⋯ This review highlights recent studies that have examined the effects of optimism on the pain experience using samples of individuals with clinically painful conditions, as well as healthy samples in laboratory settings. Furthermore, factors such as catastrophizing, hope, acceptance and coping strategies, which are thought to play a role in how optimism exerts its beneficial effects on pain, are also addressed.

Neurostimulation techniques for the treatment of primary headache syndromes, particularly for chronic cluster headache (CCH), have received much interest in the recent years. Occipital nerve stimulation (ONS) has yielded favourable clinical results, and is becoming a routine treatment for refractory chronic cluster headache in specialized centres. Meanwhile, other promising techniques, such as spinal cord stimulation (SCS) or sphenopalatine ganglion stimulation, are emerging. This article reviews the current state of clinical research for neurostimulation techniques for chronic cluster headache, and particularly the pros and cons of SCS and ONS.
