Diagnostic Criteria for Benign Paroxysmal Positional Vertigo

  • Vertigo associated with a characteristic mixed torsional and vertical nystagmus provoked by the Dix-Hallpike test

  • A latency (typically of 1 to 2 seconds) between the completion of the Dix-Hallpike test and the onset of vertigo and nystagmus

  • Paroxysmal nature of the provoked vertigo and nystagmus (i.e., an increase and then a decline over a period of 10 to 20 seconds)

  • Fatigability (i.e., a reduction in vertigo and nystagmus if the Dix-Hallpike test is repeated)

 

Common Causes of Vertigo

  • Benign paroxysmal positional vertigo

  • Meniere´s disease (hydrops endolymphayic)

  • Vestibular neuronitis (labyrinthitis)

Neurologic disorders

  • Migraine-associated dizziness

  • Vertebrobasilar insufficiency

  • Panic disorders
