Abstract

OBJECTIVE: Transcranial magnetic stimulation (TMS) uses a medical device that applies magnetic pulses noninvasively to the cortex of the brain to depolarize neurons. We tested its safety and efficacy in young persons with a diagnosis of attention-deficit/hyperactivity disorder (ADHD). METHODS: Transcranial magnetic stimulation was applied to the right prefrontal cortex at 10 Hz, at 100% of the observed motor threshold, for 2000 pulses per session, in a 10-session course over 2 weeks in a sham-controlled crossover design (n=9). There was 1 week of no TMS between the active and sham phases. Safety of TMS was assessed by means of serial audiometry, neuropsychological testing, and electroencephalogram (EEG) at baseline, midpoint, and end point of the study. Efficacy was assessed as a primary outcome by changes in the Clinical Global Impression-Improvement (CGI-I) scale and secondarily by change in the ADHD-IV scale. RESULTS: Transcranial magnetic stimulation was found to be safe, with no serious adverse events and no discontinuations due to adverse effects. All randomized subjects completed the full course of sessions. There were no significant changes in auditory thresholds or in electroencephalographic assessments. Neuropsychological testing showed no significant differences between active and sham groups. There was an overall significant improvement in the clinical global impression of improvement and the ADHD-IV scales across the study phases (active and sham TMS combined; P<0.01), but the change between active and sham TMS phases did not differ. CONCLUSION: Transcranial magnetic stimulation was found to be safe, with no serious adverse events observed in this pilot study. Improvement in symptoms was observed across the combined phases of the study, although there was no difference between the active and sham forms of TMS. Effects of clinical importance should be further assessed in larger controlled studies.

  • In Weaver et al. (2012), clinical improvement was shown in both sham and real rTMS groups, suggesting placebo effects, while no effects were observed for neuropsychological or EEG measures.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
