The painful reality of cerebellar ataxia is that, in the great majority of cases, you won’t know you have it until you start tripping over your own feet, drifting into walls, or wetting your pants. Once it shows itself, your cerebellum likely is already shrunken and damaged. Halting all wheat and gluten ingestion at this point is only likely to keep you out of the assisted living facility. All of this due to the muffins and bagels you so crave.
