Insomnia is one of the most common sleep problems,and its prevalence rate has been increasing in re-cent years.At present,cognitive behavioral therapy and drug therapy remain the main treatment methods for insomnia in clinical practice,but they are associated with the problems such as high treatment costs and great side effects.Transcra-nial direct current stimulation exerts a therapeutic effect on insomnia by imposing microelectric current stimulation to change cortical excitability,improve synaptic plasticity,increase slow wave activity,and regulate cerebral blood flow,with a favorable safety profile and mild side effects.Therefore,it may become a valuable treatment method.This article analyzes the application of transcranial direct current stimulation in the treatment of insomnia in terms of safety,instruc-tions,and mechanism of action,so as to provide new ideas for the clinical treatment of insomnia disorder.
