| Name | progressive multifocal leukoencephalopathy | 
| Definition | A viral infectious disease that involves reactivation of JC polyomavirus (Betapolyomavirus secuhominis) in immune-compromised individuals which causes the loss of white matter (which is made up of myelin, a substance the surrounds and protects nerve fibers) in multiple areas of the brain. The symptoms include hemiparesis, aphasia, dysarthria, hemianopia, cognitive impairment and coma.  https://www.ninds.nih.gov/health-information/disorders/progressive-multifocal-leukoencephalopathy, http://www.merck.com/mmpe/sec16/ch217/ch217f.html, http://www.merriam-webster.com/medical/progressive%20multifocal%20leukoencephalopathy  |
