Igor Koralnik from Rush University Medical Center: Progressive Multifocal Leukoencephalopathy a Continuing Problem Across Many Conditions

Progressive multifocal leukoencephalopathy, also known as PML is a problem which can affect a select number of patients with multiple sclerosis as well as other conditions which involve the immune system. What can be done to address the condition is still being determined by the medical community.

Igor N. Koralnik, MD, from Rush University Medical Center discussed what is known about the condition and what still needs to be learned during the annual ECTRIMS conference held in London. The virus, which can kill brain cells can be very difficult to treat as it is a progressive condition rather than a relapsing issue like that seen in multiple sclerosis. As a result, Koralnik said making the right diagnosis and addressing treatment quickly is very important. The treatment is further complicated because it can be triggered by some multiple sclerosis drugs including natalizumab.
