Central pontine myelinolysis

Central pontine myelinolysis is a neurologic disease caused by severe damage of the myelin sheath[?] of nerve cells in the brainstem, more precisely in the pons. The most common cause is the rapid correction of low blood sodium levels (hyponatremia). Some scholars postulate that the real cause might be the lack of a substance that is essential for brain activity and is lacking due to malnutrition. The fact that this condition is most frequently observed in patients with general ill health (alcoholism, cachexia[?] etc.) is in accordance with this assumption. Frequently observed symptoms in this disorder are weakness, double vision and loss of consciousness.
