From Helene Epstein:

Just an FYI: It seems that water intoxication is often confused with other causes of hyponatremia. Rapid differentiation of the conditions is critical to assure the correct treatment is instituted promptly. This information comes from a recently published study by researchers at NYU Winthrop Hospital writing in the July, 2018 issue of the American Journal of the Medical Sciences. Abstract here: <https://www.amjmedsci.com/article/S0002-9629(18)30128-9/pdf <https://www.amjmedsci.com/article/S0002-9629(18)30128-9/pdf> <https://www.amjmedsci.com/article/S0002-9629(18)30128-9/pdf <https://www.amjmedsci.com/article/S0002-9629(18)30128-9/pdf>>>

“An estimated 5 percent to 30 percent of all hospital in-patients worldwide have some form of hyponatremia. Misdiagnoses involving cerebral salt wasting are especially common, since the condition is typically thought to be tied to brain injury or disease", though the cited study found that a majority of patients with "cerebral salt wasting" actually had no neurological findings. The authors also argue for a change in terminology.

Best,
Helene
