BACKGROUND Previous studies demonstrated that a severe neurovascular contact (NVC) causing displacement or atrophy of the trigeminal nerve is highly associated with classical trigeminal neuralgia (TN). There are no studies describing the association between the clinical characteristics of TN and severe NVC. METHODS Clinical characteristics were(More)
Neurovascular contact is considered a frequent cause of classical trigeminal neuralgia and microvascular decompression with transposition of a blood vessel is preferred over other surgical options in medically refractory patients with classical trigeminal neuralgia. However, the prevalence of neurovascular contact has not been investigated in a(More)
Migraine with aura is prevalent in high-altitude populations suggesting an association between migraine aura and hypoxia. We investigated whether experimental hypoxia triggers migraine and aura attacks in patients suffering from migraine with aura. We also investigated the metabolic and vascular response to hypoxia. In a randomized double-blind crossover(More)
See Moskowitz (doi:10.1093/brain/awx099) for a scientific commentary on this article.The migraine aura is characterized by transient focal cortical disturbances causing dramatic neurological symptoms that are usually followed by migraine headache. It is currently not understood how the aura symptoms are related to the headache phase of migraine. Animal(More)
Optimal management of patients with classical trigeminal neuralgia (TN) requires specific treatment programs and close collaboration between medical, radiological and surgical specialties. Organization of such treatment programs has never been described before. With this paper we aim to describe the implementation and feasibility of an accelerated(More)
BACKGROUND AND PURPOSE The integrity of the blood-brain barrier (BBB) has been questioned in migraine, but BBB permeability has never been investigated during spontaneous migraine attacks. In the present study, BBB permeability during spontaneous attacks of migraine without aura was investigated compared to an interictal state. METHODS Seventy-four(More)
Introduction Neurovascular contact (NVC) is considered a frequent cause of classical trigeminal neuralgia (TN) and transposition of a blood vessel in the potentially dangerous procedure of microvascular decompression is considered over other surgical options in medically refractory TN. However, prevalence of NVC has not been investigated in a representative(More)
The diagnostic criteria of the third International Classification of Headache Disorders state that there should be no neurological deficits in patients with classical trigeminal neuralgia (TN) at clinical examination. However, studies demonstrating sensory abnormalities at bedside examination in TN patients have questioned this. Our aim was to examine(More)
Background Functional connectivity of brain networks may be altered in migraine without aura patients. Functional magnetic resonance imaging (fMRI) studies have demonstrated changed activity in the thalamus, pons and cerebellum in migraineurs. Here, we investigated the thalamic, pontine and cerebellar network connectivity during spontaneous migraine(More)
INTRODUCTION Persistent idiopathic facial pain (PIFP) is a poorly understood chronic orofacial pain disorder and a differential diagnosis to trigeminal neuralgia. To address the lack of systematic studies in PIFP we here report clinical characteristics and neuroimaging findings in PIFP. METHODS Data collection was prospective and standardized in(More)
