Algorithm for the diagnostic evaluation of dizziness. (HINTS = head-impulse, nystagmus, test of skew.)
Questions regarding the timing (onset, duration, and evolution of dizziness) and triggers (actions, movements, or situations) that provoke dizziness can categorize the dizziness as more likely to be peripheral or central in etiology. Findings from the physical examination can help confirm a probable diagnosis. A diagnostic algorithm can help determine whether the etiology is peripheral or central
TiTrATE is a novel diagnostic approach to determining the probable etiology of dizziness or vertigo. The approach uses the Timing of the symptom, the Triggers that provoke the symptom, And a Targeted Examination. The responses place the dizziness into one of three clinical scenarios: episodic triggered, spontaneous episodic, or continuous vestibular.
