What causes leukoencephalopathy?

What causes leukoencephalopathy?

Progressive multifocal leukoencephalopathy (PML) is a disease of the white matter of the brain, caused by a virus infection that targets cells that make myelin–the material that insulates nerve cells (neurons).

What is a leukoencephalopathy disease?

Leukoencephalopathy with vanishing white matter is a progressive disorder that mainly affects the brain and spinal cord (central nervous system). This disorder causes deterioration of the central nervous system’s white matter, which consists of nerve fibers covered by myelin.

Is leukoencephalopathy fatal?

Progressive multifocal leukoencephalopathy (PML) is a rare and often fatal viral disease characterized by progressive damage (-pathy) or inflammation of the white matter (leuko-) of the brain (-encephalo-) at multiple locations (multifocal).

Can leukoencephalopathy be cured?

Treatment. The best way to treat PML is to fight whatever has made your immune system weak. You might take drugs that attack the virus that causes AIDS (HIV) or avoid drugs that affect your immune system.

How is leukoencephalopathy related to white matter diseases?

Leukoencephalopathy ( leukodystrophy -like diseases) is all of the brain white matter diseases, whether their molecular cause is known or not. Megalencephalic leukoencephalopathy with subcortical cysts. It can also refer to gene MLC1 or Megalencephalic leukoencephalopathy with subcortical cysts 1, a human gene related to the former disease.

How does progressive multifocal leukoencephalopathy affect the brain?

Progressive multifocal leukoencephalopathy (PML) is a disease that attacks part of your brain. It happens if your body can’t fight off disease the way it should. It damages your brain’s white matter — cells that make a substance called myelin. This protects your nerves, and losing it can make it harder for you to move, think, and feel sensations.

What kind of brain damage is toxic leukoencephalopathy?
