Symptomatic cluster headache (CH) secondary to internal carotid artery dissection (ICAD) has been frequently reported, however, as far as we know, the coexistence of episodic CH and acute symptomatic CH secondary to ICAD has not. ⋯ The coexistence of episodic CH and acute CH symptomatic of ICAD in our patient suggests that, at least in some cases, CH and ICAD may be different expressions of a common underlying cause: hidden vessel wall damage. When risk factors and the change - though partial - of clinical features suggest symptomatic cases, CH patients have to be strictly monitored over time. Given the lack of a gold standard investigation for dynamic diseases such as dissections, these patients require multimodal diagnostic investigation over time, even in cases where exams are normal at onset.

The interictal deficit of habituation to repetitive visual stimuli in migraine patients could be due to deficient intracortical inhibition and/or to low cortical pre-activation levels. Which of these abnormalities contributes more to the habituation deficit cannot be determined with the common methods used to record transient visual responses.We investigated lateral inhibition in the visual cortex during the migraine cycle and in healthy subjects by using differential temporal modulations of radial windmill-dartboard (WD) or partial-windmill (PW) visual patterns. ⋯ These results are in favour of a migraine cycle-dependent imbalance between excitation and inhibition in the visual cortex. We hypothesize that an interictal hypoactivity of monaminergic pathways may cause a functional disconnection of the thalamus in migraine leading to an abnormal intracortical short-range lateral inhibition that could contribute to the habituation deficit observed during stimulus repetition.

Psychological factors can increase severity and intensity of headaches. While great attention has been placed on the presence of anxiety and/or depression as a correlate to a high frequency of migraine attacks, very few studies have analyzed the management of frustration in children with headache. Aim of this study was to analyze the possible correlation between pediatric migraine severity (frequency and intensity of attacks) and the psychological profile, with particular attention to the anger management style. ⋯ Our results suggest that children suffering from severe migraine tend to inhibit their angry feelings. On the contrary, children with low migraine attack frequency express their anger and suffer from separation anxiety.

Migraine is a common neurological disorder of unclear pathogenesis. Recently incompetence of internal jugular vein valve (IJVVI) was found to be associated with some neurological conditions of unknown etiology such as benign cough headache, primary exertional headache or transient global amnesia. Common vascular mechanism linking transiently increased cerebral venous pressure with the above mentioned conditions was then postulated. Therefore we decided to investigate whether IJVVI may be associated with migraine. ⋯ The results of our study show no evidence for an increased prevalence of IJVVI in migraine patients.

No study has been performed to compare the impacts of migraine and major depressive episode (MDE) on depression, anxiety and somatic symptoms, and health-related quality of life (HRQoL) among psychiatric outpatients. The aim of this study was to investigate the above issue. ⋯ Migraine was common and the impact of migraine on physical and pain symptoms was greater than MDE among psychiatric outpatients. Integration of treatment strategies for migraine into psychiatric treatment plans should be considered.
