The most vexing problem in hyponatremic conditions is to differentiate the syndrome of inappropriate secretion of antidiuretic hormone (SIADH) from cerebral/renal salt wasting (C-RSW). Both have identical clinical parameters but diametrically opposite therapeutic goals of water- restricting water-logged patients with SIADH or administering salt and water to dehydrated patients with C-RSW. While C-RSW is considered a rare condition, the report of a high prevalence of C-RSW in the general hospital wards creates an urgency to differentiate one syndrome from the other on first encounter. We decided to identify the natriuretic factor (NF) we previously demonstrated in plasma of neurosurgical and Alzheimer diseases (AD) who had findings consistent with C-RSW. ⋯ Hpr-WSP may be the NF in C-RSW which should be developed as a biomarker to differentiate C-RSW from SIADH on first encounter, introduces a new syndrome of C-RSW in AD and can serve as a proximal diuretic to treat congestive heart failure.
