VERTIGO vs DIZZINESS
DIZZINESS : is a balance disorder.
VERTIGO : is one of the types of Dizziness
Body Balance is Controlled by 3 Sensory Systems:Vestibular, Visual, Proprioceptive BALANCE dysfunction Imbalance /DizzinessCENTRAL NERVOUS SYSTEM(Coordination, integration)
Postural control by muscle

VISUAL(Eye)
VESTIBULAR (Labyrinth)
PROPRIOCEPTIVE(Muscle, joint, skin)
4Maintaining balance is dependent on input from a number of sourcesBalance results from a complex interaction of sensory information from several sources. The inner ears, or vestibular system sensory hair cells within the inner ear monitor the position and motion of the head in the environment. The eye visual cues are important in maintaining balance and oculomotor control. Skin pressure receptors provide information about which part of the body is in contact with the ground.Muscle and joint sensory receptors provide information on the position of the limbs in the environment.
Sensory information from all relevant sources is processed in the central nervous system (specifically the brain stem and cerebellum with additional input from the cerebral cortex). The output from this processing controls motor responses relating to eye movements, postural control and perceptual output, allowing the body to navigate in the environment. Contradictory or missing information from any of the sensory systems, or an impairment of the central processing of information can lead to forms of dizziness or imbalance, such as vertigo.

VERTIGO VESTIBULAR vs NONVESTBIULAR VESTIBULAR NONVESTIBULAR (vestibular system) (visual & proprioceptive)Sensation Spinning, rotating Swaying, floating, rocking lightheaded
Duration Episodic Constant
Precipitating factor Head or body movement Stress, hiperventilation, cardiac arrhythmia
Associated symptoms Nausea, vomit, tinitus, Paleness, paresthesia, deafness, oscillopsia syncope

Balance requires information of similar intensity from both vestibular systemsHead movement
Activation of cells in right vestibular systemActivation of cells in left vestibular system
Normally, the input from left and right vestibular system is of similar intensity (e.g. of size 10)
Central nuclei
12Balance requires information of similar intensity from both vestibular systemsMovement of the head in any direction leads to movement of sensory hair cells in both left and right semicircular canals. Both vestibular systems (labyrinths) will then send similar information of the same intensity to the central vestibular nuclei located in the brain stem (e.g., information of intensity 10). The central nervous system integrates this information from the left side and the right side, and balance is maintained providing that the information is coherent and similar in intensity.
Peripheral vestibular vertigoDysfunction of vestibular apparatus, vestibular nerve

Central nuclei10
13Peripheral vertigo results from a dysfunction in vestibular system functioningIn peripheral vertigo, the problem is located in one peripheral vestibular system or in the acoustic nerve (nerve number VIII), most often on one single side. This pathology means that there is an imbalance in the intensity of information sent from the vestibular apparatus to the vestibular nuclei in the brainstem. When the difference is important (e.g., an intensity of 5 on one side compared to the normal intensity of 10 on the other side), the central process is not able to compensate or integrate the information, and thus vertigo appears.
Any of the structural components of the peripheral vestibular system may be affected in peripheral vertigo (e.g., the sensory cells, endolymph or local microcirculation). The damage can result from several pathophysiological mechanisms including trauma, infection, and tumor. When a cause can be identified, curative treatments can restore normal balance. However, it can be difficult to establish the exact cause because access to the vestibular apparatus is restricted by their encapsulation in bone.
In the absence of an identifiable cause, or if the patient does not respond to treatment, this type of vertigo may still improve over time as spontaneous, physiological mechanisms adapt to the difference (a compensation process). This mechanism of compensation is reinforced by vestibular rehabilitation exercises but usually takes time, and is often only partially successful.
Central Vestibular Vertigo dysfunction in central processing
1010
Central nuclei
14Central vertigo results from a dysfunction in central processingIn central vertigo, the problem lies in the central nervous system, particularly in the vestibular nuclei of the brain stem. Several diseases can be responsible for dysfunction of the central nervous system by altering normal neuronal functioning or the transfer of information between vestibular nuclei. It is important to diagnose these conditions; if vertigo is a symptom of a more severe brain disease, then treatment is imperative.
The process of ageing can also be responsible for central dysfunction. Ageing may cause an excessive loss of neurons in the vestibular nuclei, a local decrease in microcirculation or a local decrease of neuronal metabolism. Changes to neurotransmission and transfer of information between the left and right nuclei can also be a consequence of ageing. These processes (alone or in combination) can result in vertigo. Indeed, vertigo is more frequently observed in older people (Sloane 1989).
In central vertigo the treatment must be focused on the brain. Nootropil is particularly suited for the treatment of central vertigo in aged people because of its activities on microcirculation, neuronal metabolism, neurotransmission and transfer of information inside the central nervous system.

16Distinguishing peripheral and central peripheral causes of vertigoVertigo can result from peripheral or central dysfunction. While the overall presenting symptom (e.g., an illusion of rotation) may be the same regardless of the cause, a number of features can provide an indication as to the location of the specific dysfunction. For example, peripheral causes usually result in vertigo of a sudden onset, with nausea and vomiting commonly reported; neurological symptoms and changes in consciousness are rare. In contrast, vertigo due to central causes is more likely to have a gradual onset and a persisting duration accompanied by severe imbalance and other neurological symptoms.
Identifying the underlying aetiology is paramount to appropriate management.

32Current management optionsBecause vertigo can result from a range of peripheral and central causes, appropriate treatment requires the identification of the most likely underlying pathology. Once this has been established, the principal aim of treatment must be to treat the underlying problem using surgery, pharmacotherapy, or, in the case of benign paroxysmal positional vertigo, particle repositioning procedures. If this is not possible (for example if a definitive cause cannot be identified) or if treating the cause will take some time, symptoms should be managed using pharmacotherapy, or long-lasting relief instigated by the use of vestibular rehabilitation exercises.

34Treatment is dependent on vertigo typeWherever possible, treatment should be directed at the underlying cause of the disease. This table shows specific treatments that can target certain types of vertigo.
Treatment for Menieres diseases could involve: restriction of salt intake to 12 g daily, diuretics (hydrochlorothiazide, acetazolamide), and surgery if these treatments fail. Recently, transtympanic low-dose gentamicin has been increasingly used. Treatment for migraine could involve: beta-blockers (propranolol 120240 mg/day), calcium channel blockers (verapamil 120240 mg/day), and tricyclic amines (nortriptyline 75100 mg/day).Treatment for vertebrobasilar insufficiency or transient ischaemic attacks could involve aspirin 75330 mg/day or ticlopidine 500 mg/day.

PREVENTION OF AGGRAVATING FACTOR
Control of Nutrition and Life-style: Adequate food and diet
Avoid excessive alcohol, tobacco
Medicine: sedative, ototoxic, opioid
Sleeping, working position.
V. PHYSICAL CONDITIONING EXERCISE
Recommend doing one or more of the following, 3 times a week:- Walking on a treadmill (1 mile) - Brisk walking outdoors (1 mile or more) - Riding a stationary bicycle- Swimming
INTEGRATED VESTIBULAR THERAPY
Therapeutic Modalities Options:1. Symptomatic treatment 2. Treatment for Specific Conditions 3. Rehabilitative therapy 4. Prevention of aggravating factor
SINGLE THERAPY or INTEGRATED THERAPY ?
Single TherapyEtiologic or Specific treatment is paramount, but it does not offer the patient a significant improvement or vertigo symptoms resolution when used alone
Symptomatic drug therapy bring improvement in 75.1% of the patients with peripheral vestibulopathies and 39.8% of the patients with central vestibular disorders
Vestibular rehabilitation therapy were efficient in 51.1% of patient when used alone
Diet and feeding habit change improve vertigo in 42.2% patients with vestibulopathies
Gananca et al. Brazilian Journal of Otorhinolaryngology 2007;73(1):12-8
INTEGRATED THERAPY
Integrated Vestibular Therapy (IVT)
A combination therapeutic modalities of Specific Treatment, Symptomatic Treatment, Vestibular Rehabilitaton Therapy, Diet Control and Life-style changes, brought about 96 % of vertigo improvement.
CONCLUSIONS
Balance function depends on the integrity of vestibular, visual and somatosensory systems. Disorder of these system (s) leads to dizziness, which includes 4 types: Vestibular Vertigo, Nonvestibular Vertigo, Presyncope, and Disequilibrium.
Treatment of vertigo includes etiologic, symptomatic, vestibular rehabilitative therapies, dietary and life habit control, and conditioning physical exercise.
Integrated Vestibular Therapy (IVT) proved to bring better resolution of vertigo compared to single therapy
Thank You
Vestibular Rehabilitation Therapy (VRT)Definition VRT is a specific form of physical therapy designed to promote habituation and compensation for deficits related to balance disorders.
VRT is effective in : - Peripheral vestibular hypofunction, unilateral and bilateral - Central balance disorders.
VRT: GOALS GOALS :Improve balance Minimize falls Decrease subjective sensations of dizziness Improve stability during locomotion Reduce overdependence on visual and somatosensory inputs Improve neuromuscular coordination Decrease anxiety and somatization due to vestibular disorientation
BY : improving vestibular function and promoting mechanisms of central adaptation and compensation

a. Semont ManeuverAlso called the liberatory maneuver
The patient is rapidly moved from lying on one side to lying on the other
Roughly an 80% cure rate (Herdman et al, 1993).
Takes about 15 minutes to complete.
Instructions For Patients After Office Treatment (1) (Epley or Semont Maneuvers)
1. Wait for 10 minutes after the maneuver is performed before going home -To avoid "quick spins, brief bursts of vertigo as debris repositions itself immediately after the maneuver. - Don't drive yourself home.
2. Sleep semi-recumbent for the next two nights - Sleep at 45 angle - During the day, keep head vertical
Instructions For Patients After Office Treatment (2) (Epley or Semont Maneuvers)
3. For at least one week, avoid provoking head positions that might bring BPPV on again: - Use 2 pillows when you sleep - Avoid sleeping on the "bad" side - Don't turn your head far up or far down - Be careful to avoid head-extended position - Try to stay as upright as possible. -. Do not start doing the Brandt-Daroff exercises immediately or two days after the Epley or Semont maneuver, unless specifically instructed otherwise by your doctor.
4. At one week after treatment, put yourself in the position that usually makes you dizzy. Position yourself cautiously and under conditions in which you can't fall or hurt yourself..
c. Brandt-Daroff maneuver
1 repetition = maneuver done to each side in turn (4x30 second = 2 minutes) 1 set = 5 repetition (5x2 minute = 10 minutes)
Schedule : 3 sets per day 2 weeks - Morning set : 5 repetitions (10 minutes) - Noon set : 5 repetitions (10 minutes) - Evening set : 5 repetitions (10 minutes) Success rate : 95% Complete relief: mostly after 30 sets ( 10 days) Recurrence: 30% in 1 year may + 1 set per day (Amin et al, 1999).

781.) Betahistine does not sedate. It has no antagonistic effects on H1 Receptors which controls wakefulness (sleep patterns and state of alertness). Betahistine stimulates H1 receptors instead of blocking them so pts remain alert. 2) Betahistine has no affinity for H2 Receptors it does not stimulate H2 receptors (which are found in the stomach) to any great extent so betahistine is generally free from gastric side effects. So far no H3 receptors have been discovered in the stomach, which might explain why no indirect H2 effects are seen. 3) Betahistine has specific interaction with H3 & H1 receptors.
4. Latihan Brandt-Daroff: Mulai dengan duduk tegak (posisi 1), lalu ber-gerak Then move into the side-lying position (position 2), with the head angled upward about halfway. ke posisi samping berbaring ( posisi 2), dengan kepala miring ke atas sekitar setengah. An easy way to remember this is to imagine someone standing about 6 feet in front of you, and just keep looking at their head at all times. (6) Cara mudah untuk mengingat ini adalah membayangkan seseorang berdiri sekitar 6 kaki di de-pan Anda, dan dan pertahankan untuk menatap kepalanya setiap saat. Tahan pada setiap posisi berbaring selama 30 detik atau sampai rasa pusing reda, Stay in the side-lying position for 30 seconds, or until the dizziness subsides if this is longer, then go back to the sitting position (position 3). jika hal ini lebih lama, kembali ke posisi duduk ( posisi 3 ).Stay there for 30 seconds, and then go to the opposite side (position 4) and follow the same routine. Menetap selama 30 detik, dan kemudian bergerak ke sisi berlawanan ( posisi 4 ) dan mengikuti rutinitas yang sama.

Otolith organs
Goebel JA. Otolaryngol Clin North Am 2000;33:48393.
103The vestibular system is the dominant sensory input guiding balanceThe dominate input into the balance system is from the vestibular system of the inner ear. This structure consists of the otolith organs (utricle and saccule maculae) and the semicircular canals, each in its own orientation (lateral, posterior and superior) (Goebel 2000; Shepard & Solomon 2000). Each semicircular canal originates from the utricle and terminates in the ampulla. Within each ampulla and otolith organ are a number of sensory hair cells that connect to the vestibular nerve, providing the brain with sensory information pertaining to the position and movement of the head.
Dysfunction of any aspect of the vestibular system will result in abnormal activation of the vestibular nerve, which may lead to vertigo.

NYSTAGMUSNystagmus is a constant, involuntary, cyclical movement of the eyeball.Type 1. Pendular (Ocular) nystagmus - Due to disturbance of visual fixation associated with loss of central vision, congenital or acquired. 2. Jerk (Vestibular) nystagmus - Due to disturbance of vestibular system, peripheral or central.
Neurophysiological mechanisms of VertigoThe main neurotransmitters in the vestibular nuclei : Cholinergic H1 histaminergic - Cholinergic system modulates the neural store - Histaminergic system stimulate the vomiting center Vestibular nuclei stimulate the vomiting center via histaminergic (H1) system.
- GABA as inhibitory signals from cerebellar Purkinje cells
- Adrenergic system inhibit vestibular activity.
- Serotonergic pathway, activated by stimuli from the gastrointestinal tract act on the vomiting center
- Dopamine (D2) agonist blocks chemoreceptor trigger zone Chemoreceptor trigger zone in the area postrema acts on the vomiting center

111Current management optionsBecause vertigo can result from a range of peripheral and central causes, appropriate treatment requires the identification of the most likely underlying pathology. Once this has been established, the principal aim of treatment must be to treat the underlying problem using surgery, pharmacotherapy, or, in the case of benign paroxysmal positional vertigo, particle repositioning procedures. If this is not possible (for example if a definitive cause cannot be identified) or if treating the cause will take some time, symptoms should be managed using pharmacotherapy, or long-lasting relief instigated by the use of vestibular rehabilitation exercises.

MODE OF ACTION BETAHISTINE1. Direct stimulation on H1 receptor in the inner ear blood vessel increasing local vasodilation as well as permeability solving the problem of endolymphatic hydrop.
2. Strong H3 receptor (autoreceptor) antagonist and increasing neurotransmitter histamine release at nerve ending in the inner ear more increase in vasodilating effect (Prophylactic effect)
3. Blocking of H3 receptor (heteroreceptor) in serotoninergic neurone Increasing serotonin release in the brainstem, which suppresses vestibular nuclei decreases vertigo (Symptomatic effect)
Betahistine is a weak H1 agonist and strong H3 antagonist

INFORMATIONS, COUNSELLING, REASSURANCE
H1 agonist dan H3 antagonistH1 dan H2 receptors act mainly at peripheral. Blocking of central receptors will induce sedative effect. H3 which is mainly found centrally is inhibitor of histamine autoreceptor at histaminic nerve terminal, it modulates release of histamine which stimlate release of exitatory neurotransmiter, glutamate and acethylcholine via stimulation of H1 receptor in the brain, thus unlike H1 antagonist which induce sedation, H3 antagonist has no sedative effect.
Vestibular Suppressants

1341.) Betahistine does not sedate. It has no antagonistic effects on H1 Receptors which controls wakefulness (sleep patterns and state of alertness). Betahistine stimulates H1 receptors instead of blocking them so pts remain alert. 2) Betahistine has no affinity for H2 Receptors it does not stimulate H2 receptors (which are found in the stomach) to any great extent so betahistine is generally free from gastric side effects. So far no H3 receptors have been discovered in the stomach, which might explain why no indirect H2 effects are seen. 3) Betahistine has specific interaction with H3 & H1 receptors.

138Treatment is dependent on vertigo typeWherever possible, treatment should be directed at the underlying cause of the disease. This table shows specific treatments that can target certain types of vertigo.
Treatment for Menieres diseases could involve: restriction of salt intake to 12 g daily, diuretics (hydrochlorothiazide, acetazolamide), and surgery if these treatments fail. Recently, transtympanic low-dose gentamicin has been increasingly used. Treatment for migraine could involve: beta-blockers (propranolol 120240 mg/day), calcium channel blockers (verapamil 120240 mg/day), and tricyclic amines (nortriptyline 75100 mg/day).Treatment for vertebrobasilar insufficiency or transient ischaemic attacks could involve aspirin 75330 mg/day or ticlopidine 500 mg/day.
