Abstract

According to the Barany Society classification of vestibular symptoms, positional dizziness or vertigo is defined as dizziness or vertigo triggered by and occurring after a change of head position in space relative to gravity. Thus, positional dizziness or vertigo should be differentiated from orthostatic dizziness or vertigo, which is triggered by and occurs upon rising. Benign paroxysmal positional vertigo (BPPV) is the most common positional vertigo and accompanied by a characteristic paroxysmal positional nystagmus. But a problem occasionally encountered in clinical practice is the presence of a positive history of BPPV with a negative diagnostic maneuver for positional nystagmus. Orthostatic hypotension may be dependent upon various neurogenic and non-neurogenic disorders and conditions. Combination of non-pharmacological and pharmacological treatment improve orthostatic tolerance.
