Vestibular Migraine.

The term vestibular migraine designates recurrent vertigo that is caused by migraine. Vestibular migraine presents with episodes of spontaneous or positional vertigo lasting seconds to days that are accompanied by migraine symptoms. Because headache is often absent during acute attacks, other migraine features have to be identified by thorough history taking. In contrast, vestibular testing serves mainly for the exclusion of other diagnoses. Treatment still lacks solid evidence. It is targeted at the underl...

Flexible, multichannel cuff electrode for selective electrical stimulation of the mouse trigeminal nerve.

The trigeminal nerve (cranial nerve V), along with other cranial nerves, has in recent years become a popular target for bioelectric medicine due to its direct access to neuromodulatory centers. Trigeminal nerve stimulation is currently being evaluated as an adjunctive treatment for various neurodegenerative and neuropsychiatric diseases despite the mechanism of action being in question. In this work, we describe the development and validation of a novel neural interface for the infraorbital branch of the t...

Strategies for interfacing with the trigeminal nerves in rodents for bioelectric medicine.

Bioelectric medicine seeks to modulate neural activity via targeted electrical stimulation to treat disease. Recent clinical evidence supports trigeminal nerve stimulation as a bioelectric treatment for several neurological disorders; however, the mechanisms of trigeminal nerve stimulation and potential side effects remain largely unknown. The goal of this study is to optimize the methodology and reproducibility of neural interface implantation for mechanistic studies in rodents.

Transcutaneous auricular vagus nerve stimulation at 1 Hz modulates locus coeruleus activity and resting state functional connectivity in patients with migraine: An fMRI study.

Correlations between the trigeminal nerve microstructural changes and the trigeminal-pontine angle features.

Morphological and microstructural changes of the trigeminal nerve due to neurovascular compression (NVC) have been reported in primary trigeminal neuralgia (PTN) patients. This investigation was to examine the relationship between the trigeminal-pontine angle and nerve microstructural changes.

Burst Occipital Nerve Stimulation for Chronic Migraine and Chronic Cluster Headache.

Occipital nerve stimulation (ONS) is widely used for headache syndromes including chronic migraine (CM) and chronic cluster headache (CCH). The paraesthesia associated with tonic stimulation can be bothersome and can limit therapy. It is now clear in spinal cord stimulation that paraesthesia-free waveforms can produce effective analgesia, but this has not been reported in ONS for CM or CCH.

Direct Lateral Canthal Approach to the Zygomaticotemporal Branch of the Trigeminal Nerve for Surgical Treatment of Migraines.

Surgical treatment of migraine headaches involves avulsion or decompression of the affected peripheral nerves. One of the sites targeted is site II, the zygomaticotemporal branch of the trigeminal nerve. Although traditionally the procedure involved either an endoscopic or transpalpebral approach to access the nerve, both methods involve general anesthesia in an operating room. The senior authors developed a new technique to directly access the nerve by means of a transverse lateral canthal extension incisi...

The safety and efficacy of neuromodulation using percutaneous electrical nerve stimulation for the management of trigeminal-mediated headshaking in 168 horses.

Early results from the use of neuromodulation by percutaneous electrical nerve stimulation for the management of trigeminal-mediated headshaking in horses were promising but lacked sufficient case numbers and long-term follow-up. The neuromodulatory procedure has since been established as EquiPENS .

Restoration of the Topological Organization of the Trigeminal System Following Trigeminal Nerve Root Injury in the Lamprey.

Two issues were examined regarding the trigeminal system in larval lampreys: (1) for normal animals, double labeling was used to confirm that the trigeminal system has a topological organization; (2) following trigeminal nerve root transections, double labeling was used to test whether the topological organization of the trigeminal system is restored. First, for normal animals, Alexa 488 dextran amine applied to the medial oral hood (anterior head) labeled trigeminal motoneurons (MNs) in the ventromedial pa...

Meningeal Mast Cells Contribute to ATP-Induced Nociceptive Firing in Trigeminal Nerve Terminals: Direct and Indirect Purinergic Mechanisms Triggering Migraine Pain.

Peripheral mechanisms of primary headaches such as a migraine remain unclear. Meningeal afferents surrounded by multiple mast cells have been suggested as a major source of migraine pain. Extracellular ATP released during migraine attacks is a likely candidate for activating meningeal afferents via neuronal P2X receptors. Recently, we showed that ATP also increased degranulation of resident meningeal mast cells (Nurkhametova et al., 2019). However, the contribution of ATP-induced mast cell degranulation in ...

Preventive Treatment for Episodic Migraine.

Episodic migraine is a debilitating condition. Preventive therapy is used to reduce frequency, duration, or severity of attacks. This review discusses principles of preventive treatment with a focus on preventive treatment options for people with episodic migraine. Specifically discussed is evidence and use of new migraine-specific treatment options for episodic migraine, such as calcitonin gene-related peptide monoclonal antibodies, a noninvasive transcutaneous electrical nerve stimulation device, and a si...

Extensor/flexor ratio of neck muscle strength and electromyographic activity of individuals with migraine: a cross-sectional study.

Neck pain is considered a common characteristic of migraine attacks. The relationship between neck pain and migraine can be explained by central sensitization of the trigeminocervical complex, where superior cervical afferents and the trigeminal nerve converge. However, few studies have evaluated motor control of cervical muscles in individuals with migraine. Thus, the purpose of the present study was to determine the extensor/flexor ratio of neck muscle strength and electromyographic activity during a test...

Temporal disconnection between pain relief and trigeminal nerve microstructural changes after Gamma Knife radiosurgery for trigeminal neuralgia.

Gamma Knife radiosurgery (GKRS) is a noninvasive surgical treatment option for patients with medically refractive classic trigeminal neuralgia (TN). The long-term microstructural consequences of radiosurgery and their association with pain relief remain unclear. To better understand this topic, the authors used diffusion tensor imaging (DTI) to characterize the effects of GKRS on trigeminal nerve microstructure over multiple posttreatment time points.

A Trigeminal Schwannoma Masked by Solely Vestibulocochlear Symptoms.

Intracranial schwannomas are most commonly associated with the vestibulocochlear nerve, often leading to hearing loss, tinnitus, and vestibular dysfunction. Much less often, a schwannoma can arise from the trigeminal nerve which can lead to facial pain, numbness, and weakness.

Gut Microbiota Dysbiosis Enhances Migraine-Like Pain Via TNFα Upregulation.

Migraine is one of the most disabling neurological diseases worldwide; however, the mechanisms underlying migraine headache are still not fully understood and current therapies for such pain are inadequate. It has been suggested that inflammation and neuroimmune modulation in the gastrointestinal tract could play an important role in the pathogenesis of migraine headache, but how gut microbiomes contribute to migraine headache is unclear. In the present study, we investigated the effect of gut microbiota dy...

Thymoquinone Inhibits Neurogenic Inflammation Underlying Migraine Through Modulation of Calcitonin Gene-Related Peptide Release and Stabilization of Meningeal Mast Cells in Glyceryltrinitrate-Induced Migraine Model in Rats.

Two main contributors of sterile neurogenic inflammation underlying migraine pain, calcitonin gene-related peptide (CGRP), and meningeal mast cells (MMCs) play a key role in the activation of the inflammatory cascade resulting in the sensitization of trigeminal nociceptors. It is well established that phytochemical agent thymoquinone exhibits multiple anti-inflammatory effects in different in vitro and in vivo models of neuroinflammation. But its effects on the CGRP release and meningeal mast cells are unkn...

Teflon™ or Ivalon®: a scoping review of implants used in microvascular decompression for trigeminal neuralgia.

Trigeminal neuralgia (TN) is characterized by jolts of pain along the distribution of the trigeminal nerve. If patients fail conservative management, microvascular decompression (MVD) is the next step in treatment. MVD is largely done by placing implant pads between the nerve and compressing vessels. We conducted a literature review to assess effectiveness and safety of Teflon™ and Ivalon® sponges for treatment of TN with MVD.

Trigeminal Pain Responses in Obese ob/ob Mice Are Modality-Specific.

How obesity exacerbates migraine and other pain disorders remains unknown. Trigeminal nociceptive processing, crucial in migraine pathophysiology, is abnormal in mice with diet induced obesity. However, it is not known if this is also true in genetic models of obesity. We hypothesized that obese mice, regardless of the model, have trigeminal hyperalgesia. To test this, we first evaluated trigeminal thermal nociception in leptin deficient (ob/ob) and control mice using an operant thermal assay. Unexpectedly,...

Greater Occipital Nerve Block for the Treatment of Chronic Migraine Headaches: A Systematic Review and Meta-Analysis.

Few treatment options exist for chronic migraine headaches, with peripheral nerve blocks having long been used to reduce the frequency and severity of migraines. Although the therapeutic effects have been observed in clinical practice, the efficacy has never been fully studied. In the past decade, however, several randomized controlled clinical trials have been conducted to assess the efficacy of greater occipital nerve block in the treatment of chronic migraine headaches.

Upregulation of Cdh1 in the trigeminal spinal subnucleus caudalis attenuates trigeminal neuropathic pain via inhibiting GABAergic neuronal apoptosis.

Trigeminal neuropathic pain (TNP) remains a tremendous clinical challenge due to its elusive mechanisms. Previous studies showed that peripheral nerve injury facilitated a selective GABAergic neuronal apoptosis in the superficial dorsal horn and contributed to the development and maintenance of neuropathic pain. It has also demonstrated that downregulation of the anaphase-promoting complex/cyclosome(APC/C) and its coactivator Cdh1 contribute to neuronal apoptosis in diverse neurodegenerative diseases. Howev...

Stimulation Pattern Efficiency in Percutaneous Auricular Vagus Nerve Stimulation: Experimental versus Numerical data.

Percutaneous electrical stimulation of the auricular vagus nerve (pVNS) is an electroceutical technology. The selection of stimulation patterns is empirical, which may lead to under-stimulation or over-stimulation. The objective is to assess the efficiency of different stimulation patterns with respect to individual perception and to compare it with numerical data based on in-silico ear models.
