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.
