Plasmapheresis to treat Osmotic Demyelination Syndrome from overly rapid plasma sodium correction.

: Osmotic demyelination syndrome results from overly rapid serum sodium correction and is often iatrogenic. We report a 50-year-old hypertensive woman on Indapamide presenting with malaise, dizziness and serum sodium less than 100mmol/l who developed osmotic demyelination syndrome after correction of the hyponatremia. Good neurological recovery was seen after plasmapheresis.
