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.
