Tysabri: Multiple Sclerosis Medication Linked to 13th Brain Infection Case

Biogen Idec Inc., a biotechnology company, announced Friday that another patient who was taking its Tysabri multiple-sclerosis medicine is infected with progressive multifocal leukoencephalopathy, or PML. Their announcement marks the 13th case of the infection in patients taking Tysabri. Three other patients have already died from taking the medication and contracting PML.
