Inclusion Criteria:
* Diagnosis of PPA according to the current consensus criteria proposed by Gorno-Tempini et al., 2011), based on the presence of progressive language impairment as the most prominent and primary cause of functional decline and the exclusion of other medical, psychiatric, or non-neurodegenerative causes,a s well as early prominent memory, visuoperceptual or behavioral disturbances;
* Diagnosis of one of the three variants of PPA (non-fluent, semantic, or logopenic) according to the consensus criteria (Gorno-Tempini et al., 2011), based on the language profile and supported by neuroimaging (FDG-PET or MRI).
* Clinical Dementia Rating scale equal or less than 1;
* The language impairment is the main neurological deficit for the patient.
Exclusion Criteria:
* Patient diagnosed with a condition other than PPA that could cause language impairment;
* History of epilepsy or presence of focal epileptiform pathology on EEG recording; ·Contraindications related to the treatments or procedures to be used (TMS and tDCS), such as ferromagnetic material, pregnancy, or breastfeeding;
* Terminal illness or active malignancy;
* Alcohol or substance abuse within the past year;
* Major psychiatric disorders (schizophrenia, schizoaffective disorders, bipolar disorder, obsessive-compulsive disorder, or personality disorders);
