How would you stat this 'poison'?

[Storyteller01]

The idea is a future based 'poison' consisting of fast growing/cloning nerve tissue. The idea is that it would create erratic connections with the creatures own nervous system, causing unpredictable spasms and possibly death from misfiring/misdirected nerve clusters. The effect would last until the the targets immne system cleared out the offending nerve tissue.

Sounds like Dex drain to me (involuntary spasms interfering with fine and eventually gross motor control).

And I'd probably consider it a Disease rather than a Poison as it does damage over a longer period of time.
