Study on the Clinical Efficacy of Transcranial Strong Alternating Current (Hi-tACS) in Patients With Neuroimmune Diseases With Insomnia

26. april 2026 oppdatert av: Xuanwu Hospital, Beijing
This study aims to comprehensively evaluate the therapeutic effects of high-intensity transcranial alternating current stimulation (hi-tACS) on insomnia symptoms in patients with idiopathic inflammatory demyelinating disorders (IIDDs) by analyzing both the overall disease characteristics of IIDDs and individual patient variability. Additionally, the study will investigate the neuroimmunomodulatory mechanisms of hi-tACS. The findings are expected to provide evidence for the clinical application of hi-tACS in managing insomnia in IIDDs and offer new insights for personalized treatment strategies.

Våpen og intervensjoner

Deltakergruppe / Arm
Intervensjon / Behandling
Eksperimentell: Neuromodulation Group
Participants receive active transcranial alternating current stimulation (tACS) using the Nexalin ADI device. Electrodes are placed on the forehead (Fp1, Fpz, Fp2 areas of the international 10-20 system; electrode size 4.45 cm × 9.53 cm) and on bilateral mastoids (two electrodes, each 3.18 cm × 3.81 cm). Each session lasts 40 minutes, once daily, for 4 consecutive weeks (5 days intervention + 2 days rest, total 20 sessions). After completing the 20 sessions, there is a 4-week follow-up period without any treatment. At the end of week 4 and at 1 month and 2 months post-treatment, participants are asked about discomfort, abnormal sensations, seizure occurrence, and treatment acceptability.
Enhet: high-intensity transcranial alternating current stimulation, hi-tACS
Operations are performed by trained and qualified researchers using the Nexalin ADI device. For both real and sham treatments, 1 electrode (4.45 cm × 9.53 cm) is placed on the prefrontal lobe (corresponding to the Fp1, Fpz, and Fp2 regions of the International 10-20 system scalp EEG recording electrodes), and 2 electrodes (3.18 cm × 3.81 cm each) are placed on the bilateral mastoids (one on each side). Each participant receives 20 sessions of tACS intervention under the same guiding instructions, once daily for 40 minutes, for 4 consecutive weeks (5 intervention days + 2 rest days per week). After completing 20 consecutive treatments, participants enter a 4-week observation follow-up period without any treatment.
Placebo komparator: Sham Neuromodulation Group
Participants receive sham stimulation using a device identical in appearance, buttons, electrodes, odor, and weight to the active device, but no current is delivered. Both participants and investigators are blinded to group assignment. The sham device produces an initial similar sensation to real stimulation to maintain blinding. The treatment schedule (once daily, 40 minutes per session, 20 sessions over 4 weeks) and follow-up assessments are identical to those in the active group.
Enhet: Sham hi-tACS
The sham treatment device is identical to the real device in all aspects (appearance, buttons, electrodes, odor, weight, etc.) except that it does not emit electrical current. Neither participants nor researchers can distinguish between the real and sham devices by appearance. This design creates an initial sensory experience similar to actual stimulation while maintaining the double-blind nature of the study.
