Filter by:Vestibular neuritis is the second cause of vertigo, it constitutes 5 to 6% of the aetiologies of vertigo in an otoneurological consultation. Infection or reactivation of a neurotropic virus of the herpes group (HSV-1) in the vestibular lymph node is thought to be the cause of the unilateral vestibular deficit. Upper vestibular neuritis is more common than lower, or total involvement. Goebel (2) explains this by an anatomical predisposition of the vestibular nerve canal to inflammation, unlike the singular nerve canal which is shorter and wider giving way to a certain degree of edema without consequence on its contents. However, the innervation territory of the superior vestibular nerve is superimposable on the territory supplied by the anterior vestibular artery. The anterior, lateral semicircular canals and the utricle are affected. Current complementary vestibular and imaging examinations cannot differentiate between inflammatory or vascular involvement in upper vestibular neuritis. The increased presence of cardiovascular risk factors in patients with upper vestibular neuritis would be an argument in favor of ischemic involvement of the anterior vestibular artery.
Post-acute sequelae of SARS-CoV-2 infection can cause multiple system function disorders, and complicated symptoms last for an extended period. The virus can cause this continued infection, or the virus causes immune system function disorder and post-infectious autoimmune disease. The clinical symptoms can be smell loss, taste loss to liver function disorder, kidney function failure, different. No matter how complicated the systems showed in the clinic, all of the symptoms are due to the specific cells being damaged. Our clinical study is focused on recovering the damaged structure and function of the cells that could restore the organ function back to normal or close to normal
Gaze stability exercise is a medical procedure for persons with unilateral vestibular disturbances such as vestibular neuritis or persons who have had tumors of their 8th nerve. They are a crucial part of the vestibular dysfunction rehabilitation protocols in health centers. These activities which involve turning one's eyes at different angles while having their eyes focused on an optotype are aimed at helping improve the vestibular ocular reflex (VOR), visual acuity during head movements and also reducing vertigo and dizziness. Study aim: This review will be establishing the effectiveness of applying gaze stability with balance exercises procedure among participants who are suffering vertigo due to vestibular neuritis. Methods: Twenty volunteers between the age of 25-59 years old, diagnosed, and confirmed to be suffering from vestibular neuritis and vertigo will be used in this study. Gaze stability exercises will be performed while patients are in a seated position. Each exercise will last for 30 seconds and be done in phases that included; eyeball movement, saccadic eye movement, pursuit eye movement, vergence eye movement, and vestibular-ocular reflex exercise. Balance exercises will be performed in a standing position including both static and dynamic training with or without closing eyes. The following outcome measures for each participant will be assessed pre-and post-treatment after completing four weeks of intervention. They include; Arabic version of Activities-Specific Balance Confidence Scale (A-ABC scale), Arabic version of Dizziness Handicap Inventory (A-DHI), Berg Balance Scale (BBS), and Katz Index of Independence in Activities of Daily Living (Katz ADL). The findings will then be subjected to statistical methods and data analysis using the SPSS toolkit. In this study we hypothesis that practicing gaze stability and balance exercises will have a positive influence on balance and activities of daily living among vestibular neuritis patients.

Vestibular neuritis is a brutal and continuous dizzying syndrome of peripheral (vestibular) origin without cochlear or other associated involvement. Specifically, vestibular neuritis is inflammation of the nerve that innervates the vestibular canals (the inner ear). It is characterized by the sudden onset of intense and prolonged vertigo accompanied by postural imbalance, nausea and vomiting, without hearing impairment or other neurological symptoms. Vestibular neuritis is the second cause of peripheral vertigo after benign paroxysmal positional vertigo. It represents approximately 7% of patients consulting for vertigo. The purpose of this study is to evaluate if wearing Boarding Ring glasses can be accelerated vestibular compensation.
When patients arrive in the waiting room of the MRI department, patients will be given the briefing note explaining the purpose of the study and how it is going. During the consultation, the radiologist will check the inclusion and non-inclusion criteria, and will take the time to answer all of the patient's questions about the study. If the patient agrees to participate in the research, the investigating doctor will obtain his consent. The MRI examination will be performed on a 3T multi-parametric MRI. Compared to the standard protocol, patients will benefit from an additional sequence of f-mRI, called resting state, and performed before injection of gadolinium contrast agent. A consultation with an ophthalmologist will also be carried out the same day, at the Adolphe de Rothschild Foundation. During this visit, an OCT examination (optical coherence tomography), a visual field as well as the measurement of visual acuity will be carried out, in accordance with the treatment usually practiced at the Adolphe de Rothschild Foundation. The subjects of the control group who agreed to participate will benefit from an MRI examination which will include, in addition to the sequences planned for these patients according to their indications, the two non-injected sequences which will be performed on patients with suspected NO. The possible existence of visual problems in the subjects of the control group will also be asked to them by interrogation. No eye exams or follow-up visits are planned, and control group participation will end after the MRI scan. Patients with NO will be seen in consultation by an ophthalmologist during a follow-up visit approximately 6 months after diagnosis. During this consultation, an OCT, a visual field and the measurement of visual acuity will be performed. This visit and the examinations carried out correspond to the usual care of patients suffering from NO and followed at the Adolphe de Rothschild Foundation Hospital.
This will be a hospital-based retrospective multi-center study on epidemiologic and clinical characteristics of optic neuritis among Chinese. The investigation will cover about 29 provinces or municipalities all around China.
Optic Neuritis (ON) is a condition that occurs in approximately 50% of individuals with relapse remitting MS, and is the presenting event in 15-20% of patients who go on to develop MS. These ON events present with a decline in vision over several days with painful eye movements. The purpose of this study is to collect pilot data on the effect of Fampridine-SR on the recovery of visual function after demyelinating optic neuritis.Our team evaluated a person with ON who had incomplete recovery which was quite bothersome to her. After a one-month treatment course Fampridine SR,her visual functioning improved. Based on this case, we present a unique opportunity to evaluate the potential benefit of Fampridine-SR as a potential treatment for persons who do not fully recover from acute ON.
In light of experimental models showing that neuronal electrical activity is crucial for the remyelination process, we hypothesize that maintenance of electrical axonal activity in the early stages of optic neuritis may promote myelin repair, limiting thereby axonal degeneration. In humans, electrical stimulation of the optic nerve has been tested mainly in ischemic neuropathy and retinitis pigmentosa, which are both associated with severe axonal/retinal pathology and poor visual prognosis. In contrast, the inflammation of the optic nerve in optic neuritis is generally transient, with less severe axonal damage at the acute phase, which would allow for better efficacy of electrical stimulation as a strategy to promote remyelination and neuroprotection.In light of experimental models showing that neuronal electrical activity is crucial for the remyelination process, we hypothesize that maintenance of electrical axonal activity in the early stages of optic neuritis may promote myelin repair, limiting thereby axonal degeneration.

The visual prognosis of optic neuritis not related to multiple sclerosis is unknown, both in terms of functional recovery and evolution. This prospective cohort study aim to assess the ophthalmological evolution of patients presenting an episode of optic neuritis (NO) not related to a multiple sclerosis or to a clinically isolated syndrome.
