International audience. Abstract Background Suicide is a major public health issue and the majority of those who attempt suicide suffer from mental disorders. Beyond psychopharmacotherapy, seizure therapies and noninvasive brain stimulation interventions have been used to treat such patients. However, the effect of these nonpharmacological treatments on the suicidal ideation and incidence of suicidality remains unclear. Here, we aimed to provide an update on the effects of seizure therapies and noninvasive brain stimulation on suicidality. Methods We conducted a systematic review of the literature in the PubMed, EMBASE, Cochrane Central Register of Controlled Trials, Elsevier ScienceDirect, and Wiley Online Library databases using the MeSH terms “Electroconvulsive Therapy”, “Magnetic Seizure Stimulation”, “repetitive Transcranial Magnetic Stimulation”, “transcranial Direct Current Stimulation”, “Cranial Electrostimulation” and “suicide”. We included studies using seizure therapies and noninvasive brain stimulation as a main intervention that evaluated suicidality, regardless of diagnosis. Results Among 1,019 records screened, 26 studies met the inclusion criteria using either electroconvulsive therapy ( n = 14), magnetic seizure therapy ( n = 2), repetitive transcranial magnetic stimulation ( n = 9), or transcranial direct current stimulation ( n = 1). We observed that studies reported significant results, suggesting these techniques can be effective on the suicidal dimension of mental health pathologies, but a general statement regarding their efficacy is premature due to limitations. Conclusions Future enquiry is necessary to address methodological limitations and evaluate the long‐term efficacy of these methods both alone and in combination with pharmacotherapy and/or psychotherapy.
