I started writing this while having Tysabri infusion number 16.

As part of each treatment the MS Nurses have to ask a series of standard questions. Are you allergic to anything. Have you had any infections, cold/flu symptoms, that kind of thing.

One question always provides an opportunity for hilarity: how has your mood been?  

Oh I'm as up and down / miserable as ever. Chortle.

This is because the delightful PML brain infection (Progressive multifocal leukoencephalopathy, sprung from the JC virus) can cause personality change as one of it's first symptoms.

And due to Tysabri's efficiency in stamping on any foreign agents in the Central Nervous System (including the body's own immune system), once it takes hold PML can lead to severe neurological disabilities and - TA-DAAAH! - death. Marvellous.

The Nurse recently told me a story about another MS patient. He was known to be miserable, antagonistic and aggressive to his family and his care team. A proper arsehole.

After a few months on Tysabri he became noticeably more cheerful. He started being more pleasant to live with, stopped picking fights, laughed easily.

The nurses noticed this, became concerned and sent him for an MRI scan which showed the early stages of PML.

Luckily they caught it in time. I wonder how he is now?
