What is Benign Paroxysmal Positional Vertigo (BPPV)?

BPPV is one of the most common causes of vertigo — the sudden sensation that you're spinning or that the inside of your head is spinning.

Benign paroxysmal positional vertigo (BPPV)(耳石移位) is one of the most common causes of vertigo — the sudden sensation that you're spinning or that the inside of your head is spinning. BPPV causes brief episodes of mild to intense dizziness. Usually, BPPV goes away on its own. If the sensation lasts more than 2 weeks, please consult a doctor. 

 

Cause of BPPV   

BPPV, or Benign Paroxysmal Positional Vertigo, is primarily caused by the displacement of tiny calcium crystals known as otoconia within the inner ear's sensory organ. 

Under normal circumstances, these otoconia remain securely positioned within the inner ear's sensory organ. However, when they become dislodged, they can freely move within the fluid-filled spaces of the inner ear, including the semicircular canals (SCCs) responsible for sensing head rotation. The posterior SCC is the most commonly affected due to its orientation. 


Symptoms of BPPV 

Here are some benign paroxysmal positional vertigo symptoms, including: 

  • Dizziness (related to head movements) 
  • Having balance problems 
  • Nausea and vomiting 
  • Nystagmus (rapid, involuntary eye movements) 

 

When to seek emergency care 

It is crucial to seek immediate medical attention if you encounter dizziness or vertigo in conjunction with any of the following symptoms: 

  • Severe headache or migraine 
  • High Temperature / Fever 
  • Having Trouble to speak 
  • Weakness in leg or arm
