Check our this site with lots of accounts of cat's who've had strokes. Mine had one last week. He developed a sudden weakness in the rear left leg of his body. He is not able to use it properly and the vet determined there was no break or damage and that it was probably a stroke. We are having to adjust as he can't jump up to where he normally eats etc. When it first happened, he started walking by leaning on a wall, cabinets, etc. To support himself. It doesn't seem to have affected him mentally and he appears to be learning to compensate. I hope this is more helpful than the other charming person who answered you. The vet didn't offer any treatment for this.
