What is progressive multifocal leukoencephalopathy (PML)?

ANSWER

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.
