Brief Summary

Primary Progressive Aphasia (PPA) is an untreatable neurodegenerative disorder that disrupts language functions. Available therapies are mainly symptomatic and recently attention has been gained by new techniques that allow for noninvasive brain stimulation such as transcranial direct current stimulation (tDCS). The primary objective of this study is to evaluate whether the application of Active tDCS (anode over the left dorsolateral prefrontal cortex- DLPFC with the cathode over the right supraorbital region) to the scalp during individualized language training, would improve naming abilities in the agrammatic variant of PPA (avPPA) more than use of one methodology alone. The effect of treatment on the clinical symptoms will be related to changes in brain activity (Magnetic Resonance Imaging, MRI and Functional near-infrared spectroscopy fNIRS) and in biological markers, using a multimodal approach. Finally, we will assess the long-term effects of this approach.
