Abstract
We present the case of a lady in her early 20s who developed over a few weeks progressive appendicular and limb ataxia and dysarthria. She was found to have a high titer of voltage-gated calcium channel antibodies (VGCCAs) and was started on immunosuppressive and immunomodulating therapy with no further worsening of her neurological status. Subsequent testing revealed that she was also TG6 antibody-positive, and a gluten-free diet was added to her management, following which improvement in cerebellar N-acetyl-aspartate (NAA) concentration (an index of neuronal health/integrity) was noted on magnetic resonance spectroscopy (MRS), while her clinical picture remained static.
