Could a single day of TMS plus a pill ease suicidal thoughts in BPD?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Assessment of pregnancy will be completed during the 1-week prior to the administration of DCS (i.e., taken the night before TMS treatment), where relevant and according to MGB IRB policy. * Participants with contraindications to TMS (e.g., metal in head or neck area), or at increased risk for adverse events (e.g., seizure history or markedly heightened risk factors for seizures, serious medical problems, implanted devices) will be excluded. * Participants with a known allergy to DCS will be excluded from the study. * No patients with involuntary hospitalization status will be recruited for the study. * No individuals who are not proficient in English will be recruited for the study * Subject does not have a PCP
