Will my kitten make it to adulthood?

I rescued a preemie orphan from a terrible place, and she was in awful shape. She was 3 weeks old, weighed 1 1/2 ounces, had fly eggs from her ribs to her butt so thick you couldn't even see her skin. In addition, she had a wolf worm in her front leg, 2 punctures where another cat bit her, fleas, and was abandoned on top of an ant hill, cold, and dehydrated. She (miraculously) overcame these things with some TLC, as she is one tough cookie.

But at about 5-6 weeks old (she weighed about 6 oz), she started showing terrible neuro symptoms, limp from the shoulders up, very spastic movement in the back legs, and head pressing. I took her too work with me, as it was a Saturday and my vet (and back-up vet) were out of town. A certified vet tech gave her fluids, and said it was all we could do. She made it to Monday, when I was able to get her to the vet first thing. The vet thought it might have been coccidia that spread to her spinal cord, and treated her accordingly. Though she went partially blind temporarily, she made it thru, and is now 8 weeks and 1 lb, and she got her first shots yesterday (yay!). I don't take a day for granted, and love her to death, but i was wondering how likely it is, with all these complications, for her to grow old?
