Reported side effects of rTMS are minor events, mainly related with cephalagia, changes in the stimulation threshold of hearing, tinnitus, local erythema, syncopal episodes and in some cases mild and transient cognitive disorders related to the area stimulated [48-51]. The most important complication described has been possible induction of seizures (<0.1%); however these seizures have not been associated with sequels or with development of epilepsy [52-54]. There are some medical and non-medical contraindications to its use, such as, the presence of metal endo-cranial, cardiac pacemakers or hearing, as well as cardiac arrhythmias, intracranial hypertension, use of medications that lower the seizures threshold and personal or family history of epilepsy [55].
