Modified Suanzaoren Decoction Versus Eszopiclone for the Treatment of Chronic Insomnia Disorder

Not Applicable
Completed
Conditions
Chronic Insomnia Disorder
Interventions
Registration Number
NCT06452953
Lead Sponsor
Central South University
Brief Summary

The purpose of this study is to observe the cognitive function and clinical efficacy of modified Suanzaoren decoction and eszopiclone in the treatment of chronic insomnia disorder patients, and to investigate the possible neural mechanisms using MRI techniques.

Detailed Description

The subjects were enrolled and divided into two treatment groups using the randomized numeric table method. Each group received either modified Suanzaoren decoction or eszopiclone treatment for a period of 4 weeks. General demographic data were collected, and changes in sleep, mood, cognitive function, and rs-fMRI before and after treatment were observed. Assessment tools included the Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), Hamilton Anxiety Scale (HAMA), and Hamilton Depression Scale (HAMD) for subjective measures, as well as the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) and polysomnography (PSG) for objective evaluation.

Primary Outcome Measures
NameTimeMethod
The improvement of insomnia before and after treatment was assessed using the Pittsburgh Sleep Quality Index4 weeks

The Pittsburgh Sleep Quality Index (PSQI) is a self-reported questionnaire that assesses sleep quality and disturbances over a one-month time interval. It consists of 19 items that generate seven "component" scores: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction.

Secondary Outcome Measures
NameTimeMethod
The anxiety condition before and after treatment is evaluated by Hamilton Anxiety Rating scale4 weeks

The Hamilton Anxiety Rating Scale (HAM-A) is a widely used tool for assessing the severity of anxiety symptoms in individuals. It consists of 14 items that measure various aspects of anxiety, including psychological, physical, and behavioral symptoms.

The cognition function before and after treatment is evaluated by Repeatable Battery for the Assessment of Neuropsychological Status4 weeks

The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) is a widely used neuropsychological assessment tool designed to evaluate cognitive function across various domains. It consists of 12 subtests that assess attention, language, visuospatial/constructional abilities, and immediate and delayed memory.

The sleep condition before and after treatment is reflected using polysomnography4 weeks

Polysomnography is a comprehensive test used to diagnose sleep disorders. It records various body functions during sleep, including brain waves, eye movements, muscle activity, heart rhythm, and breathing patterns. This information helps clinicians evaluate sleep quality and diagnose sleep disorders such as sleep apnea, insomnia, and REM behavior disorder.

The depression condition before and after treatment is evaluated by Hamilton Depression Rating scale4 weeks

The Hamilton Depression Rating Scale is a widely used tool to measure the severity of depression in individuals. It consists of 17 items that assess various symptoms of depression, such as mood, guilt, suicidal thoughts, and sleep disturbances. Each item is scored based on the severity of the symptom, and the total score indicates the overall severity of depression, with higher scores indicating more severe depression.
