Extractions: (advertisement) Synonyms, Key Words, and Related Terms: osmotic myelinolysis Background: Adams et al described central pontine myelinolysis (CPM) as a unique clinical entity. They published their findings in 1958, observing that patients who suffered from alcoholism or malnutrition developed spastic quadriplegia, pseudobulbar palsy, and varying degrees of encephalopathy or coma from acute, noninflammatory demyelination that centered within the basis pontis. Contemporary physicians recognize that CPM occurs inconsistently as a complication of severe and prolonged hyponatremia, particularly when corrected too rapidly. Standard of care requires judicious treatment of electrolyte disturbances to reduce the incidence of osmotic myelinolysis. Pathophysiology: CPM is concentrated, frequently symmetric, noninflammatory demyelination within the central basis pontis. In at least 10% of patients with CPM, demyelination also occurs in extrapontine regions, including the mid brain, thalamus, basal nuclei, and cerebellum. The exact mechanism that strips the myelin sheath is unknown. One theory proposes that in regions of compact interdigitation of white and gray matter, cellular edema, which is caused by fluctuating osmotic forces, results in compression of fiber tracts and induces demyelination. Prolonged hyponatremia followed by rapid sodium correction results in edema. During the period of hyponatremia, the concentration of intracellular charged protein moieties is altered; reversal cannot parallel a rapid correction of electrolyte status. The term "osmotic myelinolysis" is more appropriate than "central pontine myelinolysis" for demyelination occurring in extrapontine regions after the correction of hyponatremia.

Causes, incidence, and risk factors Return to top The destruction of the myelin sheath that coats nerves inhibits impulse conduction within the cell and thus decreases its ability to communicate with other cells. The most common cause of central pontine myelinolysis is a rapid, drastic change in sodium levels in the body. Most commonly, this occurs when someone is being treated for low levels of sodium ( hyponatremia ) and the levels rise too fast, but it can occasionally occur when high levels of sodium in the body (hypernatremia) are corrected too quickly. This condition does not occur spontaneously; it is a complication of either treatment for other conditions or the other conditions themselves.

Extractions: *For Medical Professionals only, registration required Central pontine myelinolysis, (also called osmotic demyelination), demyelinating disorder found in alcoholics or in association with many systemic disorders with electrolyte abnormalities. Because of the common association with rapidly corrected hyponatraemia, the term "osmotic demyelination syndrome" has been proposed. The symptoms of central pontine myelinolysis are quadriparesis, pseudobulbar palsy and changing levels of consciousness, including coma and death. Histologically, the area of myelin breakdown is sharply demarcated and displays extensive loss of oligodendrocytes, infiltration with foamy macrophages and reactive astrocytosis. At MR the lesion is characterized by T2 hyperintensity in a central pontine location ( Fig.1

Extractions: Would like to know if any research is being done on this disease on the brain stem (pons). I have it plus it has caused down beat nystagmus which prevents me from driving. The psychological impact is terrible. I also would like to find someone with this disease. So far I have not. Answer Posted By: CCF Neuro[P] MD, RPS on Saturday, March 04, 2000 Central pontine myelinosis is usually results from changes in the osmolarity (electrolyte and protein concentration) in the brain versus the blood stream. The abnormal difference between the two causes the myelin surrounding the nerve processes to become unraveled. This inturn causes dysfunction of the nerves in this area. This is not a disease, but the result from an abnormality.

Extractions: She has improved from assisted standing to self-gait walking (500 meters) over 6 weeks. Able to stand up on her own from a few limited sitting positions. Her right hand is able to hold a small cup of water. Taking a deep breath to hold on is still a difficulty. Rollover on bed is still very difficult. The strongest part of the four limbs at right leg is still having difficulty for coordinated movement. I am obviously more interested to know any chances of speeding up the process of re-myelination before it is too late. I started reading about the myelin reformation. Unfortunately, I cannot find any resources that confirm positively the process in adult brain cells. Nor is there any authority to rule out the process or point to the timing of a brain damage like CPM or other brain disorders. I started giving her Omega-3 oil, colloidal form minerals, Vitamin B6, B12. I read about IgG that may act with adult Oligodendroglia for the re-myelination process. So I give her chewable tablets of colostrums which contained high concentration of Immunoglobulin G. All these, being health food supplements, in my mind, should have minimal side effects.

Extractions: Central pontine myelinolysis Injury to the pons (brainstem) usually due to excessively rapid correction of hypernatremia (excessive sodium in the blood). Hypernatremia is not uncommon in alcoholic patients who are relatively dehydrated. Cross section of the pons with evidence of central tissue death. Gregory Pinsky MD USC Neuropathology Central pontine myelinolysis in an alcoholic patient with an admitting serum sodium of 160 (normal up to 145). During correction of his hypernatremia with infusion of a dilute (low sodium) intravenous water solution the patient became progressively sleepier until her lapsed into a coma and died. The pons is swollen with abnormal white areas where myelinolysis (death of the myelin cells that normally surround neurons) has occured.

Causes and Risks The destruction of the myelin sheath inhibits impulse conduction along the nerve cell. The most common cause of this condition is rapid correction of low sodium levels in the body (hyponatremia). Less commonly, this also occurs from rapid correction of high levels of sodium in the body (hypernatremia). Risks include hyponatremia from any cause. Alcoholism Wernicke-Korsakoff syndrome , and general ill health and malnutrition associated with serious illnesses (cachexia) increase the risk of central pontine myelinolysis. This condition does not occur spontaneously, but it results from other conditions that cause the damage. Ency. home Disease C Please read this Important notice
