In migraine most studies report an interictal deficit of habituation of visual-evoked potentials (VEP-hab) and reduced thresholds for phosphene induction (PT) by transcranial magnetic stimulation (TMS). We searched for a possible correlation between VEP-hab and PT in migraine patients and healthy controls to test whether they reflect the same pathophysiological abnormality. ⋯ We confirm that in interictal migraine VEP habituation is deficient, but magnetophosphene threshold normal. VEP-hab and PT were not correlated with each other in healthy controls or in migraineurs. This finding suggests that they index different facets of cortical excitability in migraine, i.e. a punctual normal measure of the cortical activation threshold for PT and a dynamic response pattern to repeated stimuli for VEP habituation.

The objective of this article is to elucidate the outcome, prognostic predictors and timing of surgical intervention for subdural hematoma (SDH) in patients with spontaneous intracranial hypotension (SIH). ⋯ Uncal herniation results in poor outcomes in patients with SIH complicated with SDH. In individuals with SDH ≥10 mm and decreased GCS scores, early surgical evacuation might prevent uncal herniation.

This study explored the clinical characteristics of vestibular migraine in Chinese subjects and performed a field test of the criteria of the International Classification of Headache Disorders 3rd edition beta version. ⋯ Our study showed that the clinical features of vestibular migraine in China were similar to those of Western studies. The definition of vertigo episodes and migraine subtypes of vestibular migraine in International Classification of Headache Disorders 3rd edition beta version might be modified further. More than five vertigo attacks per day within 72 hours might be helpful as far as identifying vestibular migraine patients with short-lasting attacks.

Randomized Controlled Trial
Intravenous dexketoprofen vs placebo for migraine attack in the emergency department: A randomized, placebo-controlled trial.
Migraine is a leading headache etiology that frequently presents to the emergency department (ED). In the present study, we aimed to determine the efficacy of dexketoprofen in aborting migraine headaches in the ED. ⋯ Intravenous dexketoprofen is superior to placebo in relieving migraine headaches in the ED. It may be a suitable therapy with minimum side effects in patients presenting with a migraine headache to the ED.

Sphenopalatine ganglion percutaneous radiofrequency thermocoagulation treatment can improve the symptoms of cluster headaches to some extent. However, as an ablation treatment, radiofrequency thermocoagulation treatment also has side effects. ⋯ Our data show that patients with refractory episodic cluster headaches were quickly, effectively and safely relieved from the cluster period after computerized tomography-guided pulsed radiofrequency treatment of sphenopalatine ganglion, suggesting that it may be a therapeutic option if conservative treatments fail.
