From Postural Orthostatic Tachycardia Syndrome to Radiologically Isolated Syndrome

الملخص EN

Background.

Autonomic dysfunction is common in Multiple Sclerosis (MS) patients.

Most spinal cord lesions entail some degree of autonomic nervous system dysfunction.

MS patients may develop autonomic dysfunction later in their disease course.

Methods.

We report a patient with no prior history of MS presenting with orthostatic symptoms and diagnosed initially with postural orthostatic tachycardia syndrome (POTS).

Four months later, she was diagnosed with radiologically isolated syndrome (RIS).

The diagnosis was supported by imaging and CSF analysis.

Conclusion.

Our case sheds light on the need to consider autonomic dysfunction as an initial presentation of demyelinating pathology.

Larger trials are needed to outline the possible association between POTS and RIS.
