RESUMEN
Insomnia is the second most common psychiatric disorder in clinical practice, and more than one-third of adults may experience different forms of insomnia during their lifetime, but the root causes behind insomnia need further clarification. Early evidences from twins and family studies had shown that insomnia can be attributed to genetics. In recent years, with the rapid development of gene sequencing technology, Nature Genetics had published several consecutive articles focusing on insomnia and genes, confirming that genetic factors played an important role in the occurrence and development of insomnia. Therefore, the recent research progresses on insomnia and circadian rhythm, cytokines, neurotransmitters, and other related genes were summarized in this review, which could help to understand the pathogenesis of insomnia and develop precise treatment strategies.
RESUMEN
Non-invasive brain stimulation (NIBS) is one of the fastest-growing fields of medicine today. Recent studies have highlighted the potential of NIBS as an innovative, safe, and cost-effective treatment method applied to insomnia. Starting from treatment mechanism and clinical effect, we summarize the current research status of repetitive transcranial magnetic stimulation and transcranial electrical stimulation, the two most common NIBSs used in insomnia treatment, and analyze the existing research limitations and its future development direction, in order to provide references for further promoting the clinical application of NIBS in insomnia treatment.
