International Theta-Burst Transcranial Magnetic Stimulation for PTSD United States, 2019 50 10 days of sham-controlled iTBS, followed by 10 unblinded sessions. Analysis from both participants and clinicians were recorded. Depression decreased outside of sham treatments. Significant positive changes found within PTSD-related symptoms, depression, social and occupational function. Concluded that iTBS appears to be a promising new treatment for PTSD.
International Repetitive Transcranial Magnetic Stimulation for Functional Tremor: A Random Double-Blind, Controlled Study France, 2019 33  2 month duration of active/sham repetitive TMS therapy. Depression and Anxiety were reported to decrease in active trials when compared to sham. TMS continued to decrease these symptoms over a longer period of time (up to 12 months).
International Online Repetitive Transcranial Magnetic Stimulation During Working Memory In Younger and Older Adults: a randomized within-subject comparison United States, 2019 47 Over a few weeks with only active TMS therapy applied. More studies needed into TMS in developing memory enhancement, with the likelihood that it will provide benefits to the patients.
International Effects of High-Frequency Neuronavigated Repetitive Transcranial Magnetic Stimulation in Fibromyalgia Syndrome: a Double-Blinded, Randomized Controlled Study United States, 2020 20 20 Participants split into 2 groups, one receiving TMS therapy, and the other receiving sham treatment. Fibromyalgia and visual analog-scale stiffness improved in the TMS group. Further studies needed to conclude about long-term effects of TMS.
International Repetitive TMS in Alcohol Dependence: study protocol of a randomized controlled clinical trial of efficacy and working mechanisms Netherlands, 2019 80 A randomized, single blind, controlled trial. 10 sessions of either active or sham treatments. TMS was shown to help with alcohol dependency, with an improvement in symptoms of anxiety and depression.
International Efficacy and Safety of Deep Transcranial Magnetic Stimulation for Obsessive-Compulsive Disorder: a Prospective Multicenter Randomized Double-Blind Placebo-Controlled Trial United States, 2019 99 Two groups of either active or sham treatment over the course of 6 weeks. There was a significant reduction in symptoms according to the Yale-Brown Obsessive Compulsive Scale in the group with active treatment when compared to the sham treatment. In a 1-month follow up, 45.2% of patients had a positive response in the active treatment group when compared to the sham group (11.1%).
International Effect of Repetitive Transcranial Magnetic Stimulation on Treatment-Resistant Major Depression in US Veterans: a Randomized Clinical Trial – United States, 2018 164 Double-blind, sham-controlled randomized trial over the course of 4 years. Up to 30 sessions for each participant, being allocated either a sham or genuine treatment. 81 had genuine treatment. 39% of veterans showed a remission in depressive symptoms.
International Effects of Repetitive Transcranial Magnetic Stimulation on Improvement of Mental Health and Clinical Parameters in Depressed Hemodialysis Patients: a Pilot Study 14 Active and sham treatments over the course of 4 weeks. The TMS treatment group showed a significant improvement in the Hamilton Depression Scale when compared to the sham group. Anxiety and Somatization symptoms were also reduced in the TMS group.
International Pain Trajectories of Dorsomedial Prefrontal Intermittent Theta Burst Stimulation Versus Sham Treatment in Depression United States, 2020 36 Randomized, blind trial with active and sham treatments. Pain reduction was found in the TMS group when compared to the sham group. This was constant throughout the trial.
UK Repetitive Transcranial Magnetic Stimulation for Depression: outcomes in a United Kingdom Clinical Practice United Kingdom, 2015 to 2017 73 Overview of rTMS therapy conducted between 2015 and 2017 The NHS show a similar trend found internationally – there is a significant improvement in depression and anxiety symptoms, according to the Hamilton Depression Scale. The study concludes that the NHS could make financial savings alongside patient improvement by investing in rTMS.
UK The London Psychiatry Centre Recovery Rates for Treatment-Resistant Depression with rTMS United Kingdom, 2020 252 252 participants conducted during a survey. 61% of patients went into remission, 59% of women and 62% of men had been deemed as ‘recovered’.
UK Connectivity Guided Theta Burst Transcranial Magnetic Stimulation versus Repetitive Transcranial Magnetic Stimulation for Treatment-Resistant moderate to severe Depression: study protocol for a randomised double-blind controlled trial (BRIGHTMIND) United Kingdom, 2020 368 368 participants in a double-blind trial, receiving one of two rTMS treatments. Both kinds of rTMS treatment were deemed effective in treating depression. Further studies into rTMS has also been suggested.
