BPPV

What is BPPV?

Benign Paroxysmal Positional Vertigo (BPPV) is one of the most common causes of vertigo, characterized by brief episodes of dizziness or a spinning sensation triggered by specific changes in head position. It occurs when tiny calcium carbonate crystals, called otoconia, become dislodged from their usual location in the utricle of the inner ear and move into the semicircular canals. These misplaced crystals interfere with the normal movement of fluid within the canals, sending false signals to the brain about the body’s position and balance. This leads to a sensation of spinning or imbalance, especially when turning over in bed, looking up, or bending down. Although BPPV can be alarming, it is typically not serious and can often be effectively treated with simple repositioning maneuvers. BPPV treatment usually focuses on these repositioning exercises to guide the crystals back to their correct location.

Causes

In many patients, the spinning starts suddenly without any apparent cause. This is called Primary BPPV. However, some conditions can increase the risk of BPPV like:

  • Head injury
  • Prolonged bed rest
  • Ear infections
  • After surgery
  • Migraine

The incidence of BPPV increases with advancing age. A deficiency of Vitamin D also increases the risk of getting BPPV.

Symptoms

  •  Dizziness or spinning usually brought on by a change of position like turning in bed or bending down
  •  Unsteadiness or Imbalance
  •  Nausea or vomiting

Though the episodes of spinning usually last for less than a minute, patients may feel unsteady or heavy headed.

Diagnosis

Certain positional tests like the Dix-Hallpike and Supine Roll tests are performed, preferably under the guidance of VNG, to diagnose BPPV and identify the position of the displaced crystal. BPPV treatment typically follows the confirmation of diagnosis through these positional tests. BPPV may co-exist with other vestibular problems which cause dizziness like Vestibular neuritis, Meniere’s disease, Vestibular migraine, etc. Hence, a thorough vestibular evaluation is advised to ensure appropriate BPPV treatment is provided and to rule out other possible causes.

Treatment of BPPV

Repositioning Maneuvers:
BPPV is a mechanical disorder of the inner ear caused by displacement of calcium carbonate crystals. The BPPV treatment involves a repositioning of these crystals back to their original position in the utricle. Various repositioning maneuvers have been described for BPPV treatment. A few common maneuvers are highly effective in managing BPPV:

  • Epley’s Maneuver
  • Semont’s Maneuver
  • Barbeque Maneuver
  • Zuma Maneuver
  • Gufoni Maneuver

A correctly done maneuver can provide relief to most patients of BPPV.

Post Treatment Care

After the repositioning maneuver, the patient is asked to come for a follow-up visit to make sure that all displaced crystals have been repositioned. Some patients may require additional maneuvers. Some patients experience dizziness after the treatment of BPPV which can be treated with Vestibular Rehabilitation.

Prevention & Lifestyle Tips

While BPPV cannot always be fully prevented, certain lifestyle changes and precautions may help reduce the risk of recurrence and improve overall balance health.

 

Tips to Prevent Recurrence:

    1. Maintain Healthy Vitamin D Levels:
      Research has linked Vitamin D deficiency with a higher risk of BPPV recurrence. Ensuring adequate levels through safe sun exposure, a balanced diet rich in Vitamin D (e.g., fatty fish, eggs, fortified foods), or supplementation as advised by your doctor may help prevent relapses.

    2. Be Mindful of Head Movements:
      After undergoing repositioning therapy, it is advisable to avoid sudden or jerky head movements and rapid changes in position, particularly when getting out of bed or bending over. While not a guaranteed preventive measure, cautious movement may reduce the chances of symptom recurrence.

  • Sleep Modifications (Post-Treatment Considerations):
  • Elevate Your Head: Sleeping with an extra pillow to keep the head slightly raised for a few days after treatment may help prevent the crystals from shifting again.

  • Avoid Sleeping on the Affected Side: Temporarily refraining from lying on the side that previously triggered symptoms may also be beneficial, especially during the initial recovery period.

  1. Vestibular Rehabilitation and Balance Training:
    Incorporating gentle balance exercises such as gaze stabilization, habituation exercises, or guided Vestibular Rehabilitation Therapy (VRT) may strengthen the vestibular system and help reduce sensitivity to head movements. These should be undertaken under professional supervision if symptoms persist.

  2. Stay Physically Active:
    Prolonged bed rest or physical inactivity can predispose individuals to recurrent episodes of BPPV. Engaging in regular, safe physical activity such as walking or light aerobic exercises supports general balance and vestibular function.

Manage Underlying Health Conditions:
Certain conditions like osteoporosis, migraine disorders, or chronic ear infections have been associated with an increased risk of BPPV. Addressing and managing these underlying factors can potentially reduce the chances of recurrence.

Can BPPV Be Treated at Home?

Canalith repositioning maneuvers can be safely performed by many individuals with benign paroxysmal positional vertigo (BPPV), so long as they are educated on the procedure before proceeding to perform it at home. When used appropriately, these exercises are simple, carry relatively low risk, and may hasten the resolution of symptoms.

With that said, home treatment cannot substitute professional examination in some instances. When vertigo is disproportionately acute, recurrent, or features with neurological manifestations, such as imbalance, speech impairment, or visual impairment, then it is necessary to consult a doctor. A physician is able to diagnose whether the dizziness is caused by BPPV or some other disease.

Step-by-Step: Epley Maneuver for BPPV (Right Ear Example)

One of the most widely recommended exercises to perform on BPPV, more particularly when the right ear is involved, is the Epley maneuver. It is aimed at repositioning loose calcium crystals present in the semicircular canals to a more stable area inside the inner ear that no longer causes vertigo.

Steps:

  1. Sit up with your legs straight on your bed.
  2. Turn your head 45° to the right.
  3. Lie down rapidly with your head dangling a little over the end of the bed; keep still a minute and a half.
  4. Keep your head without turning it; turn your head 90 to the left; hold 30 seconds.
  5. Lay down on your side with your nose downward; 30 seconds.
  6. Gradually sit down again.

This maneuver can be done two to three times a day until the symptoms disappear or as instructed by your healthcare provider.

How Long Does BPPV Treatment Take?

In many cases, relief of vertigo may be achieved only in one or two sessions of repositioning. Others might need repetitive exercises in a number of days or weeks, before they can feel better. Your doctor may prescribe follow-up exercises, vestibular rehabilitation therapy, or periodic check-ups to lower the chances of recurrence even after the symptoms have improved.

Is BPPV Treatment Safe for Older Adults?

Older adults are more likely to be affected by BPPV; repositioning maneuvers are generally safe and effective in patients. Caution is however required when used with pre-existing conditions of severe arthritis, spine problems or vascular disease as some movements of the head and neck may not be well received by patients. In this instance, adjustments to the maneuvers or controlled therapy within a clinical facility can be more suitable. Do not try to treat other illnesses at home without first consulting with a medical practitioner.

Prevention & Recurrence Management

BPPV may reoccur despite successful treatment, but some lifestyle interventions and exercises can be used to reduce the rate of episodes:

  • Do not keep yourself in a position that usually causes vertigo (e.g. lying on your back with your head tilted).
  • Lay down with your head raised slightly with extra pillows.
  • Add balance exercises and vestibular rehabilitation exercises into your daily routine.
  • Periodically schedule appointments with your health care provider, most so when you have regular or recurring episodes.

When to Seek Urgent Care

BPPV is not life threatening in itself but it is important to differentiate between it and other conditions which may exhibit dizziness. Attend to the doctor as soon as possible when vertigo is accompanied by any of the following:

  • Severe or acute headache.
  • Brief blurred vision or vision loss.
  • Difficulty talking or speech is slurred.
  • One side of the body may be weak, numb, or even paralyzed.

These signs could be evidence of a neurological crisis like stroke and need immediate assessment.
