The prognosis is poor when this manifests with serious neurological manifestations like seizures and obtundation. Evidence in effective management is sparse. [cureus.com]

Prognosis Dialysis disequilibrium syndrome is usually self-limited, with symptoms resolving in a short interval. The prognosis is generally favorable, and dialysis does not need to be stopped in the majority of cases. [statpearls.com]

Historically, even with swift intervention, cerebral herniation due to DDS carries a grim prognosis. [hindawi.com]

Etiology Etiological subtypes of DES have been reported and include type 1 (CAMRQ1), 2 (CAMRQ2), 3 (CAMRQ3) and 4 (CAMRQ4) which are attributed to mutations in VLDLR (9p24), CA8 (8q12.1), WDR81 (17p13.3) and ATP8A2 (13q12) genes, respectively. [orpha.net]

Although the exact pathogenesis of DDS is still debatable, multifactor pathophysiological mechanisms have been postulated like reverse urea effect, accumulation of idiogenic osmoles and paradoxical acidosis in the cerebrospinal fluid [2,5]. [cureus.com]
