What is PML?
PML (Progressive multifocal leukoencephalopathy) is caused by a virus that affects the central nervous system. PML usually occurs in people whose immune systems have been severely weakened. It leads to an irreversible decline in neurologic function and death.
Symptoms may include unusual weakness, loss of coordination, changes in vision, difficulty speaking and personality changes. There is no known effective prevention or treatment.
