Adverse effects’ questionnaire (early evaluation).

Adverse Effects Questionnaire (AEs-Q) items	Active ( subjects)				Sham ( subjects)

Data represent the number of subjects, both for active and sham tDCS sessions, that reported the specific adverse effects at T1 (immediately after tDCS) and at T2 (90 min after tDCS); if adverse effects were present, the intensity were reported (0 = absent, 1 = mild, 2 = moderate, 3 = severe).
