Vertigo

Sometimes the world feels like it is spinning. You might feel like things are moving. This is called vertigo.

It can feel like you are swaying. This can make you feel sick. You might even feel like you want to throw up.

Vertigo can make it hard to walk. It often feels worse when you move your head.

Many people feel this way at some time. It happens more often to women. It also happens more as people get older.

Some people get it from being on a ship. Other people get it from spinning around. It is a very strange feeling!

Have you ever felt like the room is spinning? This feeling is called vertigo. It is the most common type of dizziness. People with vertigo feel like they or the objects around them are moving. It can feel like spinning or swaying. This can make people feel sick or even vomit. It can also make walking very hard.

Vertigo often comes from a problem in the vestibular system. This is the part of your body that helps you keep your balance. There are two main types. One type is called peripheral vertigo. This happens because of a problem in the inner ear. The most common cause is BPPV. This happens when tiny bits of calcium break off in the ear. These bits move into the ear canals and trick the brain.

The other type is called central vertigo. This happens when there is an issue in the brain. This can be caused by things like a brain injury or a tumor. Central vertigo can be very severe. It may make it hard for a person to stand up. Vertigo is common. About 7.5% to 10% of people will have it in their lives.

Vertigo is a specific type of dizziness that feels very strange. It is the sensation that you or the world around you is moving. This movement might feel like spinning or swaying even when you are still. It can cause many other symptoms like nausea or vomiting. Some people also feel sweaty or have a hard time walking. This feeling often gets worse when a person moves their head. It is a very common issue for many people. About 7.5% to 10% of people will experience vertigo in their lives.

Vertigo usually happens because of a problem in the vestibular system. This system is the part of your body that handles balance. Doctors divide vertigo into two main groups based on where the problem is. The first group is called peripheral vertigo. This happens because of an issue in the inner ear. It can be caused by things like a common cold or a viral infection. Other causes include things like physical trauma or even certain medicines.

One common cause of peripheral vertigo is called BPPV. This stands for benign paroxysmal positional vertigo. It happens when tiny bits of calcium carbonate break off inside the ear. These bits move into the semicircular canals and trick the brain. BPPV is the most common cause of all peripheral vertigo. Most episodes of BPPV last less than one minute. Doctors can often use a test called the Dix-Hallpike maneuver to find it.

There is another type called central vertigo. This type comes from an issue in the central nervous system. This means the problem is in the brain or the brainstem. Central vertigo can be very serious and hard to manage. It might make it very difficult for a person to stand up. It can also cause things like double vision or slurred speech. Some causes include brain tumors, migraines, or even a stroke.

Many different things can cause these dizzy feelings. For example, Ménière's disease can cause vertigo along with ringing in the ears. This condition might also cause hearing loss. Vestibular neuritis is another cause that can last for several days. It is often thought to be caused by a viral infection. People can also feel dizzy after being on a ship for a long time. This is a type of motion sickness that affects the balance system.

Vertigo is a specific sensation of movement when a person is actually stationary. It often feels like the world is spinning or swaying around the individual. This sensation is different from general dizziness and is the most common type of dizziness reported. Vertigo can cause several physical reactions, such as nausea, vomiting, and perspiration. It often makes walking difficult and typically worsens when a person moves their head. This condition is quite common in the general population. Approximately 7.5% to 10% of people experience vertigo at some point. About 5% of people experience it within any given year. It is more frequent in women and becomes more common as people age.

Medical professionals classify vertigo based on where the dysfunction is located. The first category is peripheral vertigo, which involves the vestibular system in the inner ear. This system includes the semicircular canals, the vestibule, and the vestibular nerve. The second category is central vertigo, which arises from the central nervous system. This means the issue is located in the brain or the brainstem, such as the cerebellum. Doctors also use other classifications, such as objective vertigo, where stationary objects seem to move. Subjective vertigo is when the person feels they are moving themselves. Pseudovertigo is an intense feeling of rotation inside the person's own head.

Peripheral vertigo is often caused by issues within the inner ear structures. Benign paroxysmal positional vertigo, or BPPV, is the most frequent cause. BPPV accounts for 32% of all peripheral vertigo cases. It occurs when tiny pieces of calcium carbonate break off from the otoconial membrane. These pieces enter a semicircular canal and create a false sensation of motion. Other peripheral causes include Ménière's disease, which accounts for 12% of cases. This disease may involve an increase in endolymphatic fluid within the ear. Vestibular neuritis is another cause, often linked to viral infections of the inner ear. This condition can cause vertigo that lasts for several days.

Central vertigo is generally more serious and involves the central nervous system. It can be caused by lesions in the brainstem or the cerebellum. Common causes include strokes, brain tumors, or multiple sclerosis. Central vertigo may also result from migraines or epilepsy. Unlike peripheral vertigo, central vertigo may not improve quickly. It is often associated with more severe neurological deficits. These can include slurred speech, double vision, or numbness. In some cases, the imbalance is so severe that people cannot stand or walk.

To diagnose vertigo, doctors use several specialized medical tests. They often look for nystagmus, which is a period of rapid, involuntary eye movements. The Dix-Hallpike maneuver is a common test used to identify BPPV. For more complex cases, doctors might use the HINTS test at the bedside. This test combines three specific physical examinations to differentiate between central and peripheral causes. Other tools include electronystagmography (ENG) to study eye movements. Doctors may also use CT scans or MRIs to look at the brain. To check hearing, they might use pure tone audiometry or other auditory tests.

Neurochemistry plays a major role in how the body processes balance. There is a three-neuron arc that drives the vestibulo-ocular reflex, or VOR. This reflex helps the eyes stay steady during head movement. Six primary neurotransmitters are involved in this process. Glutamate helps maintain the resting discharge of vestibular neurons. Acetylcholine acts as an excitatory signal in both peripheral and central synapses. GABA is thought to be an inhibitory neurotransmitter in certain parts of the system. Other chemicals like dopamine and norepinephrine help the brain compensate for balance issues.

Understanding vertigo helps connect the study of the ears to the study of the brain. It shows how the vestibular system must communicate perfectly with the central nervous system. When this communication breaks down, the sensation of movement occurs. This connection is vital for maintaining posture and stability. Whether the cause is a tiny piece of calcium or a brain lesion, the result is a disruption of our sense of place in the world.
