Central pontine myelinolysis (CPM), also known as Osmotic demyelination syndrome, is a neurological disease caused by severe damage of the myelin sheath of nerve cells in the brainstem, more precisely in the area termed the pons, predominately of iatrogenic etiology. It is characterized by acute paralysis, dysphagia (difficulty swallowing), and dysarthria (difficulty speaking), and other neurological symptoms.

It can also occur outside the pons.[1] The term "osmotic demyelination syndrome" is similar to "central pontine myelinolysis", but also includes areas outside the pons.[2]

Central pontine myelinolysis presents most commonly as a complication of treatment of patients with profound, life-threatening hyponatremia (low sodium). It occurs as a consequence of a rapid rise in serum tonicity following treatment in individuals with chronic, severe hyponatraemia who have made intracellular adaptations to the prevailing hypotonicity.[3] Hyponatremia should be corrected at a rate of no more than 12-20 mmol/L of sodium per day to prevent central pontine myelinolysis.[3]

Although less common, it may also present in patients with a history of chronic alcoholism or other conditions related to decreased liver function. In these cases, the condition is often unrelated to correction of sodium or electrolyte imbalance.
