[Benign paroxysmal positional vertigo]

Area of Science:

• Neurology
• Otolaryngology
• Vestibular Science

Background:

• Benign paroxysmal positional vertigo (BPPV) is the leading cause of vestibular vertigo.
• This condition arises from displaced otoconia (calcium carbonate crystals) entering the semicircular canals.
• The primary symptom is recurrent vertigo triggered by changes in head position.

Purpose of the Study:

• To summarize the etiology, diagnosis, and treatment of BPPV.
• To highlight the importance of differentiating BPPV from central vertigo.

Main Methods:

• Review of diagnostic provocative tests, specifically the Dix-Hallpike maneuver.
• Description of canalith repositioning maneuvers, such as the Epley maneuver, based on affected canal.

Main Results:

• The Dix-Hallpike maneuver is crucial for diagnosing BPPV.
• Specific repositioning maneuvers effectively treat BPPV once diagnosed.
• Distinguishing BPPV from central vertigo is clinically significant.

Conclusions:

• BPPV is a common, treatable cause of vertigo.
• Accurate diagnosis via specific maneuvers is essential.
• Timely differentiation from central vertigo prevents misdiagnosis and ensures appropriate management.
