The mental lexicon is the stock of words, in long-term memory, as an association of syntactic, semantic, and phonological/orthographic structures. Being able to access word meaning rapidly and flexibly is essential for efficient communication and it involves highly specialized brain networks. Its breakdown is present in different neurodegenerative diseases, such as Primary Progressive Aphasia (PPA), Frontotemporal Dementia (FTD), and Progressive Supranuclear Palsy (PSP). Transcranial direct current stimulation can help improve language deficits in these diseases. We compared the language deficits of these patients with controls and looked for the effects of tDCS on such deficits.
