Vestibular neuritis refers to a disorder that attacks the inner earnerve, leading to inflammation. Vestibular neuritis affectsvestibulocochlear nerve, which ensures head position balance bysending information to the brain (Baloh 26). The prefix vestibularmeans the sense of balance facilitated by semi-circular canals, thesaccule, and utricle adjacent to the cochlea. Vestibular organscontain hair cells and fluid that are responsible for sending signalsto the brains regarding head movement. The suffix neuritis relates tothe nerves that are abundant in the ear. When the nerves areinfected, they provide varied messages to the brain resulting vertigoor dizziness. Before infection, a majority of people tend toexperience upper respiratory tract ailment such as common cold.
results due to viral infection, which may beaffecting specifically the inner ear or other body parts. Viralinfections associated with vestibular neuritis comprise hepatitis,herpes virus, mumps, influenza, polio, and mononucleosis. Thou theactual cause of is not clear, scientists haveclues that attach the disease to virus. Serological tests have haveshown high protein concentration during infection, which representantiviral antibodies. As a result, herpes simplex virus seems themost likely cause of (Arbusow 417). In addition,pathological studies have found the substances found in the earduring infection resemble viral lesions. Scientists perceive thevirus to spread rapidly inducing an autoimmune reaction. Theautoimmune reaction in turn causes demyelination, oedema, andinflammation of the inner ear.
On rare cases, occurs in individuals who areprone to vascular problems due to a weak immune system (Newman 2381).Other factors such as aging and head injury may also contribute to
symptoms include balance difficulties, dizziness,concentration difficulties, severe vertigo, vomiting and nausea(Hotson and Robert 680). Due to frequent blinking of the eye, anindividual is not able to pay attention to the task at hand. Semicircular canal instability causes dizziness and vomitingsensation. The symptoms exacerbate when one fails to seek medicationattention and daily routines become difficult to perform. Waking upor continuous standing becomes problematic. symptoms if left untreated lead to chronic dizziness that lasts formonths. Under severe conditions, only after treatment of the rootcause of the virus is one relieved. Nevertheless, to some individuals illness last only for a couple of days and theyrecover completely.
Effects on Organs
Severe infection loosens octoconia in the ear.Octoconia are important as they as they stimulate vestibular nerve tosignal the direction of the head depending on gravity (Halmagyi andCurthoys 43). also affects the eardrum as itleads to the development of a skin knows as cholesteamtoma behind theeardrum. Consequently, the eardrum is incapacitated from receivingsound frequencies from outside clearly(Büchele and Brandt 159). Nevertheless, does not lead to hearing loss.Hearing loss occurs when combines with otherdiseases such Meniere and labrynthitis. alsoaffects the eye. The eye tends to blink repeatedly in the directionthe ear infection. Overworking of the eye strains its veins making itpainful and weak (Fetter and Dichgans 758). Moreover, blinkingcontinuously strains the central nervous system. As a result,individuals suffering from tend to have severeheadaches especially during the day while performing their dailychores.
Videonystagmoscopy is a test used to determine unidirectional,rotational and horizontal conditions of a health or an affected ear(Chen and Wu 846). A vestibular specialist measures an individual’sability to focus on objects when the head is under rapid movement.Rotational and caloric tests indicate areflexia of nerves in thehorizontal canal and eliminate the central causes. Rotational andcaloric tests record destructive nystagyms. The tests employ anelectronic device to demonstrate any dysfunction in the horizontalcanal nerve. Doctors also use impulse tests investigate horizontalvestibulo-ocular reflex (Strupp 681).In case of an infection, theeye near the affected ear tended to move rapidly. The eye tends tomove in the direction of the affected eye. Additionally, the eye nearthe affected ear tends to have an impaired sensation, weaknesses orvision changes. When an individual experiences severe headaches andhas neurological signs, a brain MRI imaging is considered to rootsout possible diseases such as acoustic neuroma and central nervousimpairment. Doctors also analyze history of the affected individuals.Victims are asked questions concerning when vertigo started, itsfluctuation and whether they are experiencing conditions such ashearing loss. Vestibular specialists then use their vast knowledge torule out the possible cause of the ailments and propose a suitabletreatment. The symptoms of relates to fewdiseases such as labyrinthitis, which lead to loss of the ear.Consequently, after observation and one testing such as impulsetesting, a vestibular specialist is able to predict with accuracy ifan individual is suffering from .
Age groupsSusceptible to
affects individuals who are mostly under the ageof 40 to 50 years old. However, can also affectchildren raised under congested and deplorable environments. Theyouths and teens can also be affected in case of head injuries, whichaffects the semicircular canals (Aw 769). Both males and females haveequal chances of suffering from .
Treatment of vestibular neuritis involves three steps rehabilitationprogram participatory, virus treatment and vestibular neuritissymptoms management. When an individual is detected with vestibularneuritis, the first step is to alleviate the symptoms. Various drugsare administered to reduce different symptoms. Nausea and vomitingare eliminated using drugs such as metoclopramide and Zofran. Ifvomiting continues more than a week, an individual is admitted tocurb the level of dehydration. One is provided with IV fluidscombined with special medication. Dizziness is treated usingvestibular suppressant drugs such as lorazepam, Compazine, meclizineor diazepam (George 309). Due to negative health effect uponlong-term use, vestibular suppressants are used approximately onemonth. One limitation of the drugs is that if used for a long time,recovery becomes difficult. In addition, vestibular suppressants maylead to the development of skin allergies or weaken the body nervoussystem among other causes. Depending on the condition, steroids areused to improve one’s health.
Treatment of vestibular neuritis is applied if it results from herpesvirus infection. Medication for herpes virus such as acyclovir hasbeen developed. Vestibular neuritis is not treated using antibiotics,as does not result from bacterial infection. Treatment of vestibularneuritis has shown to be effective when the cause is herpes virus,with only 5% of inflicted individuals experiencing a recurrence(Huppert 1870).
Continuous dizziness calls for a balance rehabilitation program. Insevere cases, vestibular neuritis lasts for more than a week. Arehabilitation program is essential to help the brain recover fromthe conditioned changes. Vestibular therapist analyzes the affectedareas of the body that aid in body balancing. The therapist evaluatesthe balance of legs when a victim attempts to walk, how the eyes areable to interpret objects positions in the environment and thefunctioning of the inner ear. Moreover, a vestibular therapist isable to evaluate the posture of the entire body with respect togravity. He/she observes if an individual sways during movement, orif one demonstrates unsteady posture. After examining various bodyparts, a therapist is able to design an effective program for aparticular client. If vestibular neuritis disease affected the wholebody posture, one is recommended to shift the body backward andforward on all sides while standing. The vestibular therapist is ableto measure improvement displayed by a client, and the exercise manytake one to two weeks. If the effect was is on the ear or eye, onemay be requested focus on a particular object while shifting the headin various direction (Choi 1310). Other rehabilitation measuresinclude keeping a fixed vision while rotating the head. Furthermore,an individual can be requested to maintain a steady glance on adistant object while approaching it. Therapy rehabilitation programsinsist an exercise to be repeated three times (Perols 894). As aresult, an individual is able to adapt to the initial body changes.
Vestibular neuritis is a disease that affects the inner ear causingbody imbalance. The disease is assumed to be a viral infection, andit affects both males and females. Vestibular neuritis symptomsinclude dizziness, nausea, and vomiting. It can be cured using duringsuch as acyclovir or vestibular rehabilitation program.
