Understanding Osmotic Demyelination Syndrome

Osmotic demyelination syndrome (ODS), also called central pontine myelinolysis (CPM) and extra-pontine myelinolysis (EPM), is a demyelination of the pons region of the central nervous system that interrupts the flow of information within the brain and body.


R

Demyelination:

Destruction of myelin, the insulating layer around axons, essential for the proper functioning of the nervous system.
Demyelination

ODS is most often derived as a complication of treatment of patients with hypontremia (low serum sodium).


Correcting for hyponatremia too rapidly in the hospital can lead to:


myelin sheath

Acute damage of the myelin sheath in the pons area of the brain

Patient Care

Patient care is primarily supportive only

long-term disability

Serious long-term (chronic) disability and potentially death

No cure or treatment

There is no cure or specific treatment currently available


Clinical Signs and Symptoms


1

ODS is first diagnosed clinically and confirmed by MRI. However, it often takes days to several weeks after acute symptoms occur for confirmation of demyelination of the pons to be detected by MRI.
