Cerebellar clamp occurs shortly after (within hours) of an acute unilateral vestibular injury. Cerebellar degeneration, injury or sedation could definitely affect compensation. Also, things like fatigue, stress, anxiety, illness or change in vestibular function can trigger decompensation.
What is vestibular decompensation?
Vestibular Decompensation means there is a reversal of the central compensation process that has previously occurred in the brain to correct for inner ear damage – or vestibular system damage. Vestibular decompensation occurs due to a lack of head motion.
What can affect compensation for vestibular disease?
Cerebellar degeneration, injury or sedation could definitely affect compensation. Also, things like fatigue, stress, anxiety, illness or change in vestibular function can trigger decompensation.
What can cause decompensation of the cerebellar clamp?
Cerebellar clamp occurs shortly after (within hours) of an acute unilateral vestibular injury. Cerebellar degeneration, injury or sedation could definitely affect compensation. Also, things like fatigue, stress, anxiety, illness or change in vestibular function can trigger decompensation.
How does the brain compensate for vestibular damage?
After the initial compensation phase, the cerebellum slowly releases the clamp, gradually allowing more signals from the inner ear to pass to the brain. The brain can then fine-tune its calculations in order to account for differences between the signals received from damaged versus undamaged vestibular organs.
How long does vestibular decompensation last?
Most patients make a slow but full recovery over two to three months. Even after a few months, it is possible to experience some slight dizziness particularly with movements or turning the head quickly.
What triggers vestibular disorders?
Infections. Inner ear problems, such as poor circulation in the ear. Calcium debris in your semicircular canals. Problems rooted in your brain, such as traumatic brain injury.
What can damage vestibular system?
Ear infections may also cause damage to the vestibular and hearing structures of the inner ear, including the nerves that transmit signals from the ear to the brain. High doses or long-term use of certain antibiotics can be ototoxic, meaning they cause permanent damage to the inner ear.
How does vestibular nerve get damaged?

What is the condition that affects the nerve that sends sound and balance information from your inner ear to your brain?
Vestibular neuritis: A viral infection somewhere else in your body, such as chickenpoxor measles, can bring on this disorder that affects the nerve that sends sound and balance information from your inner ear to your brain. The most common symptoms are sudden dizziness with nausea, vomiting, and trouble walking.
What is the link between the inner ear and the brain?
A link between your inner ear and your brain helps you keep your balance when you get out of bed or walk over rough ground. This is called your vestibular system.
What are the symptoms of vertigo?
Dizzinessand trouble with your balance are the most common symptoms, but you also can have problems with your hearing and vision. Common Vestibular Disorders. Benign paroxysmal positional vertigo (BPPV): This is the most common cause of positional vertigo, a sudden feeling that you’re spinning or swaying.

How long does it take for vestibular compensation to occur?
For most patients, the movements made during normal daily activities are enough to achieve chronic (long-term) vestibular compensation, usually in two to four weeks after the injury has occurred.
What does it mean when the brain forgets the fine tuning it developed during the chronic compensation phase?
Decompensation simply means that the brain has ‘forgotten’ the fine-tuning it developed during the chronic compensation phase described above. Events that can provoke decompensation include a bad cold or the flu, minor surgery, or anything that interrupts normal daily activity for a few days, such as long trips.
What happens after the initial compensation phase?
After the initial compensation phase, the cerebellum slowly releases the clamp, gradually allowing more signals from the inner ear to pass to the brain. The brain can then fine-tune its calculations in order to account for differences between the signals received from damaged versus undamaged vestibular organs.
What happens when the brain recognizes that the signals being received from the ears are incorrect?
Researchers theorize that after this initial period, the brain recognizes that the signals being received from the ears are incorrect and turns the signals down through a process called the cerebellar clamp.
Why do we need to compensate for injuries?
First, the brain must continue to receive signals from the balance organs so that it can learn how to interpret different head movements. Thus, movements must not be avoided, because they create the signals the brain needs to compensate for the injury. Second, the areas of the brain that are responsible for compensation must not be damaged.
Can anti-dizziness medications slow down the process of compensation?
Any medication that makes the brain sleepy, including all of the anti-dizziness medications, can slow down or stop the process of compensation, so they are often not appropriate for long-term use.
What is vestibular compensation?
Vestibular Compensation. Vestibular compensation is often referred to as central compensation. In the world of vestibular function, central generally refers to brain function, while peripheral generally refers to ear function. This is an important distinction because in many cases of peripheral or inner ear dysfunction, ...
What causes decompensation?
Decompensation (return of symptoms) can be triggered by fatigue, sedating medications or alcohol, and/or complex environments such as a busy grocery store.
How do the right and left vestibular nuclei communicate?
The right and left vestibular nuclei communicate with each other through commissural connections. With any head movement there is an increase in discharge to the vestibular nuclei on one side, with a corresponding decrease in discharge on the opposite side.
What is normal vestibular function?
Normal Vestibular Function. In a normal functioning vestibular system, when the head is still, the discharge at the level of the vestibular nuclei is equal; therefore, the eyes are still when the head is still. Again, in a normal functioning vestibular system, when the head moves, the activity at the level of the vestibular nuclei changes.
What causes sudden reduction of output?
A sudden injury to the labyrinth such as a vestibular neuritis causes a sudden reduction in output from the affected side. This results in asymmetric discharge at the level of the vestibular nuclei even while the head is still. This is perceived as persistent motion, resulting in eye movements known as nystagmus.
How long does it take for nystagmus to reduce?
This process involves dampening of the neural activity between the brain and the healthy inner ear, resulting in gradually reduced asymmetric input. This process is characterized by gradual reduction in intensity of vertigo and nystagmus over 24 to 72 hours following onset of the vestibular injury.
What causes a stable inner ear?
Stable inner ear dysfunction most often occurs as a result of vestibular neuritis/labyrinthitis, but can also occur from vesti bular dysfunction related to Ménière’s disease or related treatments such as intra-tympanic gentamicin or vestibular nerve section. In these situations the responsiveness of the labyrinth may be permanently reduced.
How long does it take for vertigo to return after a balance system injury?
For many patients, dizziness and vertigo will return months or years after compensating for a balance system injury. It is critical for the physician to find out what type of dizziness and vertigo the patient has. If the patient describes another severe attack of spinning with unsteadiness and nausea lasting hours to days, this suggests that a second injury has occurred to the balance system, such as another viral infection or an attack of Ménière’s disease or secondary endo-lymphatic hydrops. These conditions require diagnosis and medical treatment. If the patient reports that dizziness occurs after particular movements and lasts seconds to a few minutes, this suggests that de-compensation has occurred. De-compensation simply means that the brain has ‘forgotten’ the fine-tuning it developed during the chronic compensation phase described above.
What happens during the acute compensation phase?
During the acute compensation phase, the cerebellum slowly releases the clamp, gradually allowing more signals from the inner ear to pass to the brain. The brain can then fine-tune its calculations in order to account for differences between the signals received from damaged versus undamaged vestibular organs. Such compensation can’t occur if the cerebellar clamp remains in place.
Why are movements not necessary?
Two things are required in order to compensate for an injury. First, the brain must receive signals from the balance organs. Thus, movements must not be avoided, because movements create the signals the brain needs to compensate for the injury. Second, the balance areas of the brain must be capable of change.
What does it mean when your brain is decompensated?
Decompensation simply means that the brain has 'forgotten' the adaptation that it put in place to restore you to a normal life. Any interruption to your daily routine, a cold, flu or stress may trigger Decompensation. Despite the absence of any infection, you will be stripped back to the symptoms that you initially had. This will manifest itself as dizziness or disequilibrium lasting seconds to minutes after certain movements.
Is decompensation the same as recovery?
Recovery from Decompensation is exactly the same as it would be from your original condition but is much FASTER. Unfortunately, the brain will quickly associate certain environmental situations as triggers for "dizzy spells" and can lead to Panic Attacks which can also cause dizziness. This convinces the patient that the original condition has returned. In the case of Decompensation, this is in fact untrue.
