Orthostatic dizziness is a common type of dizziness. In general, orthostatic dizziness is provoked by standing or tilting, and subsided by supine position. The patient with orthostatic intolerance complains multiple symptoms such as dizziness, palpitation, lightheadness, fatigue and rarely syncope. Common orthostatic intolerance is orthostatic hypotension (classic, initial, transient, and delayed orthostatic hypotension) and postural orthostatic tachycardia syndrome. Transcranial Doppler is a noninvasive technique that provides real-time measurement of cerebral blood flow velocity. It can be useful for understanding the relationship between orthostatic symptoms and cerebral autoregulatory function. The reciprocal causal relationship between vestibular and autonomic dysfunction should always be kept in mind.

Abstract PDF: 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.
