Brief summary: Insomnia disorder (ID) is a significant public health problem worldwide, with nearly a third of the general population experiencing insomnia symptoms in their lifetime. Therefore, finding a safe, effective, and easy-to-use non-pharmacological method for treating ID is urgent. Repetitive transcranial magnetic stimulation (rTMS) has been used to varying degrees in many neurological and psychiatric diseases and has broad application prospects for treating ID.θ-burst stimulation is characterized by cluster stimulation.Continuous stimulation (cTBS) mainly has inhibitory effects on the cortex. The inhibition of motor-evoked potentials can last for 60 minutes, which is longer-lasting, has a lower stimulation intensity, and is shorter in duration than traditional rTMS. There are no reports on clinical studies of cTBS treatment for ID. So far, sleep research has mainly focused on the interconnections between the neocortex and subcortical structures, while cerebellar activity has been largely overlooked.The mechanism of rTMS treatment for insomnia with the cerebellum as the target is unclear. This study proposes to apply cTBS mode to the cerebellar dentate nucleus for rTMS treatment in patients with ID to explore its effectiveness and safety in improving insomnia disorder.


Eligibility criteria: Inclusion Criteria:

* All participants aged from 18 to 60 years old; all participants met diagnostic criteria for insomnia disorder according to the Diagnostic and Statistical Manual of Mental Disorders-V (DSM-V), and scored \>10 on PSQI , ≤14 on the Hamilton Anxiety Scale (HAMA), and ≤17 on the Hamilton Depression Scale (HAMD); no sleep-affecting drugs were taken 1 month before or during the trial (non-prescription sleep medication, benzodiazepines or hypnotics, ect.); patients can cooperate to complete the treatment and related examination items; all subjects signed informed-consent forms before enrolling in the trial.

Exclusion Criteria:

* The patient is unable to cooperate with the completion of treatment and examinations; there are other types of sleep disorders; a history of psychotropic drug or alcohol dependence or abuse in the last 2 years; have undertaken trans-meridian travel across more than two time zones or worked night shifts in the preceding one month or during the trial period; plan surgical treatment within 1 month before or during the trial; evidence of neurological or other physical diseases such as respiratory, cardiac, renal, hepatic, endocrinal diseases and other psychiatric diseases as assessed by clinical history, physical examination or routine laboratory tests; pregnancy or breastfeeding women; any contraindication for rTMS (including implanted metal and devices in the body, and history of epilepsy); concurrent other clinical trials; patient or family member withdraws informed-consent.
