Trigeminal Neuralgia Trigeminal Neuralgia Trigeminal Nerve (Cranial Nerve V) and Its 3 Regions of Innervation Acial Pain Has a Number of Causes JAMA PATIENT PAGE The Journal of the American Medical Association NEUROLOGY Trigeminal Neuralgia Trigeminal neuralgia Trigeminal nerve (cranial nerve V) and its 3 regions of innervation acial pain has a number of causes. Trigeminal neuralgia (TN) is named for the nerve (the trigeminal, or fifth cranial nerve) Fthat is affected. Trigeminal neuralgia causes brief, intense, BRAIN severe pain, usually on one side of the face or the jaw or near the V eye. Trigeminal neuralgia is a type of neuropathic pain (pain caused 1 by nerves). V V 2 Trigeminal neuralgia is more common in people older than 50 years 3 and tends to affect women more than men. It may occur in other family members. Researchers think that TN is caused by pressure on the trigeminal nerve from a blood vessel. Persons with TN may be treated by neurologists, medical doctors who specialize in the treatment of conditions affecting the nerves and the brain.

  • Trigeminal Isolated Sensory Neuropathy (TISN) and FOSMN
    Cruccu et al. BMC Neurology (2014) 14:248 DOI 10.1186/s12883-014-0248-2 RESEARCH ARTICLE Open Access Trigeminal isolated sensory neuropathy (TISN) and FOSMN syndrome: despite a dissimilar disease course do they share common pathophysiological mechanisms? Giorgio Cruccu1*, Elena M Pennisi2, Giovanni Antonini3, Antonella Biasiotta1, Giulia di Stefano1, Silvia La Cesa1, Caterina Leone1, Salvatore Raffa4, Claudia Sommer5 and Andrea Truini1 Abstract Background: Patients presenting with bilateral trigeminal hypoesthesia may go on to have trigeminal isolated sensory neuropathy, a benign, purely trigeminal neuropathy, or facial-onset sensory motor neuronopathy (FOSMN), a malignant life-threatening condition. No diagnostic criteria can yet differentiate the two conditions at their onset. Nor is it clear whether the two diseases are distinct entities or share common pathophysiological mechanisms. Methods: Seeking pathophysiological and diagnostic information to distinguish these two conditions at their onset, in this neurophysiological and morphometric study we neurophysiologically assessed function in myelinated and unmyelinated fibres and histologically examined supraorbital nerve biopsy specimens with optic and electron microscopy in 13 consecutive patients with recent onset trigeminal hypoesthesia and pain. Results: The disease course distinctly differed in the 13 patients. During a mean 10 year follow-up whereas in eight patients the disease remained relatively stable, in the other five it progressed to possibly life-threatening motor disturbances and extra-trigeminal spread. From two to six years elapsed between the first sensory symptoms and the onset of motor disorders. In patients with trigeminal isolated sensory neuropathy (TISN) and in those with FOSMN neurophysiological and histological examination documented a neuronopathy manifesting with trigeminal nerve damage selectively affecting myelinated fibres, but sparing the Ia-fibre-mediated proprioceptive reflex.

In addition to the paroxysmal pain, some patients also have continuous pain. TN is divided into classical TN (CTN) and secondary TN (STN). Etiology and pathophysiology: Demyelination of primary sensory trigeminal afferents in the root entry zone is the predominant pathophysiological mechanism. Most likely, demyelination paves the way for generation of ectopic impulses and ephaptic crosstalk. In a significant proportion of the patients, the demyelination is caused by a neurovascular conflict with morphological changes such as compression of the trigeminal root. However, there are also other unknown etiological factors, as only half of the CTN patients have morphological changes. STN is caused by multiple sclerosis or a space-occupying lesion affecting the trigeminal nerve. Differential diagnosis and treatment: Important differential diagnoses include trigeminal autonomic cephalalgias, posttraumatic or postherpetic pain and other facial pains. First line treatment is prophylactic medication with sodium channel blockers, and second line treatment is neurosurgical intervention. Future perspectives: Future studies should focus on genetics, unexplored etiological factors, sensory function, the neurosurgical outcome and complications, combination and neuromodulation treatment as well as development of new drugs with better tolerability.

Robertson, MD Correspondence Dr. Robertson Neurology 2019;93:124-131. doi:10.1212/WNL.0000000000007790 ® [email protected] Section 1 A 47-year-old man presented with right-sided facial pain that started 2 years prior. He described the pain as extremely intense, stabbing along the right jaw, lasting 5–60 seconds. This pain was exacerbated by chewing, and to a lesser degree, by brushing his teeth. The pain was so intense that he avoided eating when possible, leading to a 20-pound weight loss. When he did eat, he would try to chew on the left side of his mouth. Around the onset of these symptoms, he also noticed a persistent numbness and burning extending from the right lower earlobe to the lateral angle of the jaw that was exacerbated by turning his head to the right. The patient was given a diagnosis of atypical trigeminal neuralgia (TN) and sent to our headache clinic for further management. Questions for consideration: 1. What features are typical and atypical for classical TN? 2. What is your differential diagnosis in this patient presenting with facial pain?

  • Osteopetrosis Associated with Familial Paraplegia: Report of a Family
    Paraplegia (1975), 13, 143-152 OSTEOPETROSIS ASSOCIATED WITH FAMILIAL PARAPLEGIA: REPORT OF A FAMILY By SKIP JACQUES*, M.D., JOHN T. GARNER, M. D., DAVID JOHNSON, M.D. and C. HUNTER SHELDEN, M. D. Departments of Neurosurgery and Radiology, Huntington Memorial Hospital, Pasadena, Ca., and the Huntington Institute of Applied Medical Research, Pasadena, Ca., U.S.A. Abstract. A clinical analysis of three members of a family with documented osteopetrosis and familial paraplegia is presented. All patients had a long history of increased bone density and slowly progressing paraparesis of both legs. A thorough review of the literature has revealed no other cases which presented with paraplegia without spinal cord com­ pression. Although the etiologic factor or factors remain unknown, our review supports the contention that this is a distinct clinical entity. IN 1904, a German radiologist, Heinrich Albers-Schonberg, described a 26-year­ old man with multiple fractures and generalised sclerosis of the skeleton. The disease has henceforth commonly been known as Albers-Schonberg disease or marble osteopetrosis, a term first introduced by Karshner in 1922. Other eponyms are bone disease, osteosclerosis fragilis generalisata, and osteopetrosis generalisata. Approximately 300 cases had been reported in the literature by 1968. It has been generally accepted that the disease presents in two distinct forms, an infantile progressive disease and a milder form in childhood and adolescence. The two forms differ clinically and genetically. A dominant pattern of inheritance is usually seen in the benign type whereas the severe infantile form is usually inherited as a Mendelian recessive. This important distinction has not been well emphasised.

  • Genetic Studies of Human Neuropathic Pain Conditions: a Review Katerina Zorina-Lichtenwalter*, Marc Parisien, Luda Diatchenko
    NeuPSIG Reviews Genetic studies of human neuropathic pain conditions: a review Katerina Zorina-Lichtenwalter*, Marc Parisien, Luda Diatchenko Abstract Numerous studies have shown associations between genetic variants and neuropathic pain disorders. Rare monogenic disorders are caused by mutations of substantial effect size in a single gene, whereas common disorders are likely to have a contribution from multiple genetic variants of mild effect size, representing different biological pathways. In this review, we survey the reported genetic contributors to neuropathic pain and submit them for validation in a 150,000-participant sample of the U.K. Biobank cohort. Successfully replicated association with a neuropathic pain construct for 2 variants in IL10 underscores the importance of neuroimmune interactions, whereas genome-wide significant association with low back pain (P 5 1.3e-8) and false discovery rate 5% significant associations with hip, knee, and neck pain for variant rs7734804 upstream of the MAT2B gene provide evidence of shared contributing mechanisms to overlapping pain conditions at the molecular genetic level.

  • What Is Trigeminal Neuralgia? Trigeminal Neuralgia (TN) Is a Problem with Your Trigeminal Nerve That Causes Severe Facial Pain
    Trigeminal Neuralgia GENERAL INFORMATION: What is trigeminal neuralgia? Trigeminal neuralgia (TN) is a problem with your trigeminal nerve that causes severe facial pain. You have a trigeminal nerve on each side of your face. The nerves allow you to feel pain, touch, and temperature changes in different areas of your face. What causes trigeminal neuralgia? The exact cause of your TN may not be known. The following can cause the nerve to send pain messages to your brain: • Pressure from blood vessels in the head • Pressure from a tumor or cyst • Injury to the nerve from head trauma, surgery, or a stroke • Damage from other diseases, such as multiple sclerosis (MS) What are the signs and symptoms of trigeminal neuralgia? TN causes sudden, sharp, or burning pain. It normally occurs on one side of your face but can occur on both sides. • Pain attacks that last from 1 second up to 2 minutes and repeat every few minutes to hours • Pain attacks that get worse over time • Pain that is so severe you cannot eat, drink, or speak • Spasms (twitches) in your facial muscles during your pain attack • Days to years without attacks What can trigger a pain attack? Most TN pain attacks are brought on by touching a trigger area on your face: • Eating or drinking • Smiling, yawning, or talking • Shaving or washing your face • Putting on makeup or combing your hair • Wind or temperature changes • Noise or lights How is trigeminal neuralgia diagnosed? Your caregiver will ask about your symptoms and when they started. Tell him if you have any close family members with TN.
