Differential diagnosis of orthostatic dizziness with persistent postural-perceptual dizziness and its underlying mechanisms.

ABSTRACT: Persistent postural-perceptual dizziness (PPPD) is characterized by one or more symptoms of dizziness, unsteadiness, or non-spinning vertigo, which persist on most days for at least 3 months. The most common symptom of PPPD worsens when standing or walking, often leading to confusion with other forms of orthostatic dizziness (OD). There are some main differential diagnosis as follows: hemodynamic OD, postural orthostatic tachycardia syndrome, vestibular syncope, BPPV, bilateral vestibulopathy, primary orthostatic tremor, sensory neuropathy, neurodegenerative disorders, cerebral small vessel disease associated with gait disorders, dizziness due to cardiac problems, orthostatic cerebral hypoperfusion syndrome, intracranial hypotension, and the possible mechanisms by which these diseases are
