Primary Progressive Aphasia is a neurodegenerative disorder primarily affecting language. We applied GABA-edited MRS to examine GABA changes with anodal tDCS to augment language-therapy for patients with PPA. With tDCS targeting the left inferior frontal gyus, we see a decrease in IFG GABA following the intervention. No changes were observed in the sham group. While all patients showed improvements with language therapy, those receiving tDCS showed greater improvements that were maintained at 2 months follow-up. This work supports the use of tDCS to augment language therapy in PPA.
