![]() ![]() Spontaneous episodes of vertigo caused by abnormal bone growth in the middle ear and associated with conductive hearing loss Spontaneous episodes of vertigo associated with unilateral hearing loss caused by excess endolymphatic fluid pressure in the inner ear ![]() Spontaneous episodes of vertigo caused by inflammation of the vestibular nerve or labyrinthine organs, usually from a viral infection Transient triggered episodes of vertigo caused by dislodged canaliths in the semicircular canals Symptoms of vestibular neuritis are relieved with vestibular suppressant medications and vestibular rehabilitation. Treatment of Meniere disease includes salt restriction and diuretics. Benign paroxysmal positional vertigo can be treated with a canalith repositioning procedure (e.g., Epley maneuver). Laboratory testing and imaging are not required and are usually not helpful. The physical examination includes orthostatic blood pressure measurement, a full cardiac and neurologic examination, assessment for nystagmus, and the Dix-Hallpike maneuver. The HINTS (head-impulse, nystagmus, test of skew) examination can help distinguish peripheral from central etiologies. Central etiologies often require urgent treatment. Peripheral etiologies are usually benign. Evaluation focuses on determining whether the etiology is peripheral or central. Episodic vertigo not associated with any trigger may be a symptom of vestibular neuritis. Vertigo with unilateral hearing loss suggests Meniere disease. Episodic vertigo triggered by head motion may be due to benign paroxysmal positional vertigo. Patients have difficulty describing the quality of their symptoms but can more consistently identify the timing and triggers. However, the distinction between these symptoms is of limited clinical usefulness. It was traditionally divided into four categories based on the patient's history: vertigo, presyncope, disequilibrium, and light-headedness. Dizziness is a common yet imprecise symptom. ![]()
