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.

To evaluate the resting-state visual network functional connectivity in patients with migraine with aura and migraine without aura during the interictal period. ⋯ Our imaging data revealed that patients with migraine with aura exhibit an altered resting-state visual network connectivity. These results support the hypothesis of an extrastriate cortex involvement, centred in the lingual gyrus, a brain region related to mechanisms underlying the initiation and propagation of the migraine aura. This resting-state functional magnetic resonance imaging finding may represent a functional biomarker that could differentiate patients experiencing the aura phenomenon from patients with migraine without aura, even between migraine attacks.

Tension-type headache (TTH) is highly prevalent in the general population, and it is characterized by increased muscle tenderness with increasing headache frequency and intensity. ⋯ Patients with TTH exhibited decreased muscle strength in the neck extensor muscles, inducing a reduced cervical extension/flexion ratio compared to healthy people.

This cross-sectional study investigated associations between chronic headache (CH) with and without medication overuse, healthy lifestyle behaviour, and stress. ⋯ Results suggest strong links between healthy lifestyle behaviour and stress in MOH. Stress reduction and promoting healthy behaviour are highly relevant in MOH management.

Reversible cerebral vasoconstriction syndrome in the context of recent cerebral venous thrombosis: Report of a case.
Reversible cerebral constriction syndrome and cerebral venous thrombosis are two rare conditions. Reversible cerebral constriction syndrome affects the cerebral arteries and the pathology is still largely unknown. To date, no physiological link with cerebral venous thrombosis has been reported. ⋯ The co-occurrence of cerebral venous thrombosis and reversible cerebral constriction syndrome in the same patient raises the issue of a potential link between them. We discuss the potential common trigger factors in this case: recent hormonal therapy; intracranial hypotension iatrogenically induced by lumbar puncture.
