Prognosis


Newline Maker

What is the prognosis for individuals diagnosed with progressive multifocal leukoencephalopathy (PML)?

The mortality rates for those with HIV-PML have fallen dramatically from approximately 90 percent to around 50 percent according to most reports. For non-AIDS individuals with PML, the prognosis remains grim; the disease usually lasts for months and 80 percent die within the first 6 months, although spontaneous improvement has been reported.  Those who survive PML can be left with severe neurological disabilities.[1]
