Inclusion criteria
Inclusion criteria: (1) According to the "Chinese Classification and Diagnostic Criteria of Mental Disorders, 3rd Edition (CCMD-3)", the patient meets the diagnostic criteria for generalized anxiety disorder during a depressive episode, and also meets the diagnostic criteria for insomnia, including both A and B criteria. The patient also meets the diagnostic criteria for generalized anxiety disorder (GAD) in the "Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5)". (2) The patient meets the diagnostic criteria for depression and insomnia in the "Standards for Diagnosis and Therapeutic Effect of Traditional Chinese Medicine Diseases and Syndromes" (ZY/T001.1-001.9-94, issued by the State Administration of Traditional Chinese Medicine on June 28, 1994), specifically the syndrome types of liver qi stagnation and heart-kidney disharmony. The patient also meets the diagnostic criteria for chronic insomnia disorder in the "International Classification of Sleep Disorders, Third Edition (ICSD-3)" or DSM-5, characterized by difficulty falling asleep, maintaining sleep, or early awakening, occurring on at least three nights per week for at least three months. (3) The patient is aged 18 to 60 years old, right-handed, and has at least a junior high school education. (4) The patient has a score of 14 or higher on the 14-item Hamilton Anxiety Scale (HAMA). (5) The patient has a total score of 7 or higher on the Pittsburgh Sleep Quality Index (PSQI). (6) The patient has a disease duration of at least 6 months and has not received anti-anxiety medication, traditional Chinese medicine, physical or psychological treatment in the past 6 weeks. (7) The patient has a total score of 7 or lower on the Hamilton Depression Rating Scale (HAMD), and a mandatory score of 0 on the item for suicidal ideation. (8) The severity of insomnia is confirmed through a baseline full-night polysomnography (PSG), meeting at least one of the following criteria: sleep onset latency (SOL) > 30 minutes, wake after sleep onset (WASO) > 30 minutes, or sleep efficiency (SE) < 85%. (9) The patient has sufficient cognitive ability to understand the content of the scales and sign the informed consent form, and voluntarily participates in this study. Only patients who meet all the inclusion criteria above can be included in this study. The research team invited specialized doctors from the Department of Psychosomatic Medicine to provide systematic training on the inclusion and exclusion criteria and clinical scales to the researchers. The Hamilton Anxiety Scale and Hamilton Depression Scale are scored by specialized doctors.
Exclusion criteria
Exclusion criteria: (1) A score of more than 7 on the 17-item Hamilton Depression Rating Scale (HAMD); (2) Anxiety attacks secondary to other mental or physical disorders and those with severe psychotic symptoms; (3) A previous diagnosis of intellectual disability, schizophrenia, bipolar disorder, substance abuse (such as alcohol dependence), or other mental disorders; (4) A history of epilepsy or a strong positive family history of epilepsy, brain organic diseases, or severe physical diseases; (5) Those who have been taking anti-anxiety or anti-depression drugs within 6 weeks (including 6 weeks); (6) Pregnant, planning to become pregnant, or breastfeeding; (7) Those with concurrent skin lesions or skin diseases, severe diabetes, tumors, or severe organ dysfunction or serious internal diseases such as liver, kidney, cardiovascular, endocrine, respiratory system, hyperthyroidism, and hematological system diseases; (8) Those with contraindications for MRI such as pacemakers, heart stents, claustrophobia, or recent hair dyeing. (Note: Those who meet this criterion will not be included in the neuroimaging mechanism subgroup but can remain in the main clinical trial cohort) Those with structural brain abnormalities before enrollment, such as intracranial space-occupying lesions, brain malformations, severe stroke (affecting brain structure), or other central or peripheral nerve diseases. (Note: Those who meet this criterion will not be included in the neuroimaging mechanism subgroup but can remain in the main clinical trial cohort) (9) Those with other organic sleep disorders, such as restless legs syndrome (RLS). (10) Those diagnosed with obstructive sleep apnea (OSA) based on baseline polysomnography (PSG), with an apnea-hypopnea index (AHI) > 5 times per hour. (11) Those with periodic limb movement disorder (PLMD), with a periodic limb movement sleep index (PLMSI) > 15 times per hour. (12) Those with evidence of paradoxical insomnia (poor perception of sleep state), with baseline PSG parameters not reaching the threshold for insomnia severity: sleep onset latency (SOL) = 30 minutes, wake after sleep onset (WASO) = 30 minutes, or sleep efficiency (SE) = 85%. (13) Those with irregular sleep patterns or currently engaged in long-term night shift work. Any individual meeting any of the above criteria will be excluded from the study.
