I heard about a case of this yesterday (although I had heard of it before) and quick look at a neurology book I happened to see this morning reveals that it can occur after a viral or bacterial infection, so it is of interest to this blog.
Here is some information about Guillain Barré syndrome, also known as acute inflammatory or postinfective polyradiculoneuropathy):
NHS Direct Health Encyclopaedia
Guillain Barré Syndrome Support Group
Who was Guillain? And Barré? (Information from whonamedit.com)
(Pedantic linguistic note: I know I have missed off the accent in the title of this post but if I include it, I fear it will not be found in searches for "barre").
