Benign Paroxysmal Positional Vertigo

Benign Paroxysmal Positional Vertigo (BPPV) is a mechanical vestibular disorder characterized by brief, episodic vertigo triggered by specific changes in head position relative to gravity. It is the most common cause of peripheral vertigo in adults, resulting from the displacement of otoconia within the semicircular canals of the inner ear.

BPPV is primarily idiopathic. However, secondary causes include head trauma, viral labyrinthitis, prolonged bed rest, or inner ear surgery. It involves the detachment of calcium carbonate crystals (otoconia) from the utricular macula.

The condition is caused by canalithiasis or cupulolithiasis. Dislodged otoconia enter the semicircular canals (most commonly the posterior canal). When the head moves, these particles shift, causing endolymphatic flow that deflects the cupula, triggering an abnormal vestibular signal and nystagmus.

BPPV is most common in individuals aged 50–7

1. It shows a female predilection (approximately 2:1). The lifetime prevalence is estimated at 2.4%.

Age, female gender, history of head trauma, migraines, Meniere’s disease, vestibular neuritis, and sedentary lifestyle.

A. Early Symptoms

• Mild dizziness


• Occasional imbalance B. Common Symptoms


• Brief episodes of spinning vertigo (seconds to minutes)


• Triggered by rolling in bed, looking up, or bending over


• Nausea C. Advanced Symptoms


• Chronic instability


• Persistent lightheadedness


• Falls (in elderly patients) D. Emergency Symptoms


• Vertigo accompanied by focal neurological deficits (slurred speech, weakness, ataxia)


• Loss of consciousness


• Sudden hearing loss

Nystagmus (typically torsional and upbeat) triggered by the Dix-Hallpike maneuver.

A. Clinical Assessment: Dix-Hallpike maneuver (for posterior canal) or Supine Roll test (for horizontal canal).
B. Laboratory Testing: Generally not required.
C. Imaging Studies: Reserved for atypical presentations to rule out central pathology.
D. Functional Tests: VNG (Videonystagmography).
E. Biopsy Findings: None.
F. Genetic Testing: Not indicated.
G. Differential Diagnosis: Meniere’s disease, Vestibular migraine, Vertebrobasilar TIA, Vestibular neuritis.

None specifically required for routine diagnosis.

MRI Brain/Internal Auditory Canal: Used only if central nervous system involvement is suspected (e.g., non-fatigable nystagmus or focal neurological deficits).

• Vestibular Migraine: Usually lacks the strict positional triggers of BPPV.
• Vestibular Neuritis: Characterized by constant, prolonged vertigo.
• Brainstem Stroke: Features neurological "red flags" and persistent symptoms.

Falls, especially in the elderly; driving accidents; anxiety or avoidance behaviors.

A. Lifestyle Modifications: Sleeping with head elevated, avoiding triggering positions.
B. Preventive Measures: Avoiding head trauma.
C. Medical Treatment: Generally ineffective; vestibular suppressants (meclizine) may be used for symptom control but hinder vestibular compensation.
D. Surgical Treatment: Posterior canal plugging (extremely rare).
E. Interventional Procedures: Epley Maneuver, Semont Maneuver.
F. Rehabilitation: Vestibular rehabilitation exercises (Brandt-Daroff).
G. Emergency Management: Evaluation for central causes if symptoms are persistent.

Excellent. High rates of success with canalith repositioning maneuvers. Recurrence is common (approx. 30% within a year).

No specific primary prevention. Secondary prevention involves regular repositioning maneuvers if recurrence occurs.
