Postural orthostatic tachycardia syndrome in a patient with relapsing-remitting optic-spinal multiple sclerosis: A case report and discussion of possible mechanism

ABSTRACT

Postural orthostatic tachycardia syndrome (POTS) is characterized by orthostatic intolerance, a presentation of autonomic dysfunction which is frequently observed in the patients with multiple sclerosis (MS). Nevertheless, to date, there have been a few studies focusing on POTS in MS patients and the underlying pathomechanism. We present a 28-year-old woman with relapsing-remitting opticspinal multiple sclerosis who also suffered POTS and discuss the possible pathomechanism of POTS in MS.
