BrainWaves: A Neurology Podcast


Feb 16, 2017

In 1959, Adams and colleagues described a few patients who developed a rapid flaccid quadriparesis following fluid resuscitation for malnutrition and chronic alcoholism. Twenty years later, we learned that this occurs as a consequence of rapid correction of hyponatremia. But this isn't the only cause of the osmotic demyelination syndrome... Hear Dr. Joshua VanDerWerf discuss the history and clinical relevance of this unusual critical care scenario.
