Benign Paroxysmal Positional Vertigo

Benign paroxysmal position vertigo (BPPV) is a disorder characterized by brief, recurrent bouts of vertigo. Vertigo is a sensation of spinning, whirling or turning. Individuals often feel as if the room is moving or spinning and they can lose their balance and have difficulty standing or walking. During the vertigo spells, affected individuals often have abnormal eye movements as well (nystagmus). BPPV is most often triggered by changes in head position. The severity of the disorder varies. In some people, it only causes mild symptoms, while in others it can potentially cause more severe, even debilitating symptoms. BPPV may disappear but sometimes it persists recurrently for many months. Most affected individuals can be easily and effectively treated by non-invasive methods such as canalith (or canalolith) repositioning maneuvers. However, BPPV may recur even after effectively treated. BPPV is believed to be caused by the displacement of small calcium carbonate crystals within the inner ear. These tiny crystals originate from the gravity and acceleration sensing structures and become inappropriately located in one of three semicircular canals, which are tiny, interconnected, looped tubes that serve to detect movements of the head and play a role in helping the body maintain balance. The exact, underlying cause of this displacement is not always known (idiopathic). Recurrences are possible because additional calcium can become dislodged. The treatment maneuvers move the calcium particles back to the main vestibule, the chamber from which they originated. This stops the vertigo. However, the maneuvers do not prevent the shedding of additional calcium crystals in the future.[rx]

Benign Paroxysmal Positional Vertigo, or BPPV, is a common inner ear problem that causes dizziness and imbalance. In this article, we’ll explain BPPV in plain English, covering its types, causes, symptoms, diagnostic tests, treatments, and drugs. Our goal is to make this complex topic easy to understand and accessible for everyone.[rx]

Benign Paroxysmal Positional Vertigo (BPPV) is a condition where you feel sudden spinning or dizziness, often when you change the position of your head. It happens because tiny calcium crystals in your inner ear get out of place. This can happen for various reasons, and we’ll explore those next.

Types of BPPV

BPPV mainly has two types:

1. Posterior Canal BPPV: This is the most common type, where the dizziness happens when you tilt your head backward or lie down.
2. Horizontal Canal BPPV: With this type, the dizziness occurs when you turn your head sideways.

Now, let’s dive into what causes BPPV.

Causes of BPPV

Researchers believe that most cases of BPPV are caused by abnormalities affecting the inner ear. The inner ear contains the cochlea, which converts sound pressure from the outer ear into nerve impulses that are sent to the brain via the auditory canal. The inner ear also contains a vestibular apparatus for balance that includes of the semicircular canals. Fluid moves through these canals enabling the brain to detect turning movements of the head.[rx]

Two additional structures found in the inner ear are the utricle and saccule (otolith organs). The utricle and saccule are fluid-filled sacs or cavities that detect acceleration movements of the head including gravity. The utricle and saccule contain small calcium carbonate crystals. For unknown reasons, in individuals with BPPV these crystals may partially erode and small pieces of the crystals fall off and end up in one of the adjoining semicircular canals. Within the canals, these crystals may stimulate specialized sensing organ of the inner ear tubes that is called the cupula. This results in the body being sensitive to certain head position changes that normally would not cause dizziness. Basically, the brain is sent powerful asymmetric nerve signals that resemble the kind of asymmetry associated with spinning. This gives a patient the same sensation that would occur with spinning.[rx]

Two specific theories proposed in regard to the underlying cause of BPPV are the canalithiasis and cupulolithiasis theories. These proposed mechanisms are not mutually exclusive and there is scientific evidence that both occur, but that canalithiasis is more common than cupulolithiasis. Canalithiasis refers to calcium crystals that are freely mobile within the semicircular canals and, whenever the head changes position, these crystals move through the canal. As these crystals move, they are believed to drag the fluid within the canals, known as endolymph, behind them. As the endolymph moves through the canals, it stimulates the hair cells of the cupula causing vertigo and nystagmus. When the head is not moving, the crystals (and therefore the endolymph) do not move as well. Consequently, there is no stimulation of the cupula and no associated vertigo or nystagmus. It is believed that these crystals eventually dissolve or fall back into the vestibule (the cavity at the entrance to one of the canals). Canalithiasis appears to best explain most cases of BPPV.[rx]

Cupulolithiasis refers to crystals that have become stuck or attached to the cupula in one of the three semicircular canals, usually the posterior canal. BPPV caused by cupulolithiasis is believed to account for the more persistent cases of BPPV that do not respond as well to positioning treatments.[rx]

Several things can cause those pesky ear crystals to misbehave and lead to BPPV. Here are 20 common causes:

1. Aging: As we get older, our inner ear can become more sensitive to changes in position.
2. Head injuries: A blow to the head can dislodge the crystals.
3. Ear infections: Infections can affect the inner ear and lead to BPPV.
4. Ear surgery: Past ear surgeries might disrupt the ear’s balance.
5. Meniere’s disease: People with this condition are more prone to BPPV.
6. Viral infections: Some viruses can affect the inner ear.
7. Dehydration: Not drinking enough water can trigger BPPV.
8. Prolonged bed rest: Staying in bed for a long time can cause ear crystals to shift.
9. Certain medications: Some drugs can affect your inner ear balance.
10. Migraines: People with migraines are more at risk.
11. Osteoporosis: Weaker bones can lead to BPPV.
12. Vestibular neuritis: This condition can damage the inner ear.
13. Stress: High stress levels can worsen BPPV symptoms.
14. Blood vessel problems: Issues with blood flow to the inner ear can contribute.
15. Alcohol and caffeine: Overconsumption can trigger BPPV.
16. Inactivity: Lack of physical activity may increase the risk.
17. Genetics: Family history can play a role.
18. High salt diet: Too much salt can affect fluid balance in the inner ear.
19. Neck problems: Neck injuries or conditions can lead to BPPV.
20. Dental procedures: Certain dental work might cause BPPV symptoms.

Next, let’s explore the common symptoms of BPPV.

Symptoms of BPPV

BPPV can bring about several uncomfortable symptoms, including:

1. Vertigo: A feeling of spinning or dizziness when you move your head.
2. Nausea: Feeling sick to your stomach because of the dizziness.
3. Vomiting: In some cases, the nausea can lead to throwing up.
4. Loss of balance: Difficulty staying upright and a risk of falling.
5. Nystagmus: Rapid eye movements, often when you experience vertigo.
6. Disorientation: Feeling confused and disoriented during an episode.
7. Anxiety: Feeling anxious due to the unpredictable nature of the symptoms.
8. Sweating: Excessive sweating during an episode.
9. Headache: Sometimes, BPPV can trigger headaches.
10. Tinnitus: Ringing or buzzing sounds in the ears.
11. Hearing loss: Temporary or permanent hearing changes are rare but possible.
12. Fatigue: Feeling tired after experiencing BPPV episodes.
13. Unsteadiness: A sensation of unsteadiness even between episodes.
14. Difficulty concentrating: Concentration can be challenging during episodes.
15. Motion sensitivity: Increased sensitivity to movement.
16. Neck pain: Some individuals may experience neck discomfort.
17. Blurry vision: Vision can become unclear during episodes.
18. Lightheadedness: Feeling light-headed during an episode.
19. General discomfort: An overall sense of feeling unwell.
20. Depression: Long-term BPPV can lead to feelings of depression due to its impact on daily life.

Vertigo in individuals with BPPV usually lasts less than 30 seconds. Vertigo can lead to unsteadiness and a loss of balance. Additional symptoms can develop including lightheadedness, dizziness, nausea, vomiting, and blurred vision. Nausea or a feeling of queasiness can persist for a short time even after the sensation of vertigo has passed.[rx]

A common associated finding with BPPV is nystagmus, an eye movement disorder characterized by rapid, involuntary movements of the eye. The eyes may be described as jumping or twitching in certain directions. Nystagmus associated with BPPV is fatigable meaning that if one repeats the position change that induced the original vertigo and nystagmus, after time nystagmus lessens in severity.[rx]

Now, let’s move on to the diagnostic tests used to identify BPPV.

Diagnostic Tests for BPPV

Doctors use various tests to diagnose BPPV. Here are 20 common ones:
