Apart from traditional medication and psychotherapy, European and American clinical research findings showed that TMS provides great results for depression and insomnia. In 2013, scientists divided 120 chronic insomnia patients into three groups and received 1) TMS therapy, 2) drug therapy (Estazolam), and 3) cognitive behavioral therapy for two weeks. Results show that patients treated with TMS experienced a 25% increase in sleep time. In addition, their prolongation of rapid eye movement (REM sleep) and slow-wave sleep (slow-wave sleep) improved by 80% compared with before treatment, which was a greater improvement than the other groups. Clinical studies reported that hyperactivity of cortex in patients with insomnia. Therefore, having efficient slow-wave-sleep is especially helpful for more effective memory consolidation, fatigue reduction, and general restoration. The same study also confirmed that TMS can help reduce the brain’s stress hormone – cortisol to near-healthy levels.

Neuroscientists have integrated 28 studies – a total of 2357 individuals with insomnia. All of which received 2-4 weeks of TMS and the results showed a significant improvement in their sleep quality. It is believed that TMS can be used to complement or even replace traditional drug therapy and psychotherapy to regulate the activity of neurotransmitters, reduce excitability by stimulating the relevant area and  increase the neuroplasticity of the brain.
