It could affect patients who take some prescription medicines that are able to cross the blood-brain barrier and cause abnormal thirst reception - in this scenario the central pontine myelinolysis is caused by polydipsia leading to low blood sodium levels (hyponatremia).In schizophrenic patients with psychogenic polydipsia, inadequate thirst reception leads to excessive water intake, severely diluting serum sodium. With this excessive thirst combined with psychotic symptoms, brain damage such as central pontine myelinolysis may result from hyperosmolarity caused by excess intake of fluids, (primary polydipsia) although this is difficult to determine because such patients are often institutionalised and have a long history of mental health conditions.It has been observed following hematopoietic stem cell transplantation.Central pontine myelinolysis may also occur in patients prone to hyponatremia affected by:

Severe liver disease (e.g., cirrhosis)
Liver transplant
Alcoholism
Hypokalemia
People with serum sodium <105 mEq/L
Severe burns
Malnutrition
Anorexia nervosa
Severe electrolyte disorders
HIV/AIDS
hyperemesis gravidarum
Hyponatremia due to peritoneal dialysis
Wernicke encephalopathy

Pathophysiology
The currently accepted theory states that the brain cells adjust their osmolarities by changing levels of certain osmolytes like inositol, betaine, and glutamine in response to varying serum osmolality. In the context of chronic low plasma sodium (hyponatremia), the brain compensates by decreasing the levels of these osmolytes within the cells, so that they can remain relatively isotonic with their surroundings and not absorb too much fluid. The reverse is true in hypernatremia, in which the cells increase their intracellular osmolytes so as not to lose too much fluid to the extracellular space.With correction of the hyponatremia with intravenous fluids, the extracellular tonicity increases, followed by an increase in intracellular tonicity.
