Central pontine myelinolysis

Central pontine myelinolysis (CPM), also known as Osmotic demyelination syndrome or Central pontine demyelination, 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.
