Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The circadian rhythm characteristics of sleep cycle and neuroendocrine in patients with chronic disorder of consciousness show different degrees of disorder, and the relationship between this disorder and consciousness level is unclear.The researchers used HD-tDCS to treat patients with chronic disturbance of consciousness who intervened in circadian rhythm, and used a variety of methods such as EEG, fMRI, protein metabolism, ERP and micro-expression to explore the mechanism of improving the state of consciousness of HD-DCS and the relationship between circadian rhythm and patients' consciousness level

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The sleep status (\> 24 hours) of patients with chronic disturbance of consciousness was recorded with the revised coma recovery scale revised (CRS-R) and Polysomnography (PSG). The sleep cycle of patients with chronic disturbance of consciousness was judged by the open and close eyes cycle and EEG.

Patients with circadian rhythm treated with or without blue light stimulation and melatonin were treated with HD-tDCS. EEG, fMRI, protein metabolism, ERP and micro expression data were recorded before and after treatment.Explore the mechanism of improving the state of consciousness of HD-DCS and the relationship between circadian rhythm and patients' consciousness level

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

tDCS and melatonin intervention

In real tDCS, the current was increased to 2 mA from the onset of stimulation and applied for 20 minutes. Participants were given a 3-mg fast-release oral dose of melatonin.

Group Type EXPERIMENTAL

Melatonin

Intervention Type DRUG

Participants assigned to the melatonin group were given a 3-mg fast-release oral dose of melatonin administered at approximately 21:00

HD-tDCS

Intervention Type OTHER

Direct current was applied using a battery-driven constant-current stimulator through saline-soaked surface sponge electrodes (7cm×5cm) with the anode placed over the left DLPFC (F3 according to the 10-20 international EEG system) and the reference cathode placed over the right supraorbital region (Fp2). During real tDCS, the current was increased to 2 mA from the onset of stimulation and applied for 20 minutes

tDCS intervention

In real tDCS, the current was increased to 2 mA from the onset of stimulation and applied for 20 minutes.

Group Type EXPERIMENTAL

Placebo

Intervention Type OTHER

Participants in this group were treated according to a protocol identical to those receiving active medication at approximately 21:00. For the sham tDCS groups, the same stimulation parameters were employed, except that the stimulator had a built-in placebo mode; when it was activated, two ramp fade-in/fade-out periods in the beginning and the end of sham stimulation mimicked the somatosensory artifact of real tDCS
