I have heard large doses of Vit E really helps with any neuro damage.
Best of luck!!
In addition to using anti-protozoal medications, some experts recommend supplementing with 6,000-9,000 IU per day of vitamin E. Although no control trials have been done to support this, Blythe points out that, "Vitamin E has been shown in people and horses to augment or make the immune system work better. Vitamin E may help the immune system do the final killing (of the parasite) where antibiotics don't destroy all of it."
