Dialysis disequilibrium syndrome
In nephrology, dialysis disequilibrium syndrome, commonly abbreviated DDS, is the occurrence of neurologic signs and symptoms, attributed to cerebral edema, during or following shortly after intermittent hemodialysis.
Classically, DDS arises in individuals starting hemodialysis due to chronic renal failure and is associated, in particular, with "aggressive" (high solute removal) dialysis. However, it may also arise in fast onset, i.e. acute, renal failure in certain conditions.
