Effects of Transcranial Temporal Interference Stimulation on Risky Decision-making and Impulse Control in Gambling Disorder
Sponsor: Shanghai Mental Health Center
Summary
The purpose of this research is to investigate the effect of transcranial temporal interference stimulation (tTIS) targeting the dorsal anterior cingulate cortex in patients with gambling disorder.

Interventions
tTIS on dACC, theta frequency (5 Hz)
Device: Transcranial electric stimulation device The first pair of electrodes continuously outputs a current with a frequency of f1 = 2 kHz, while the second pair continuously outputs a current with a frequency of f2 = 2.006 kHz. According to the principle of time-domain coherence, an alternating electric field with a frequency of f2-f1 = 6 Hz can be generated in the target area. The experimental group receives a stimulation intensity of 2mA for 20 minutes. The optimal electrode position and current parameters are determined by using the MIDA head electric field model.
tTIS on dACC, High frequency
The first pair of electrodes continuously outputs a current with a frequency of f1 = 2 kHz, while the second pair continuously outputs a current with a frequency of f2 = 2 kHz. The sham group receives a stimulation intensity of 2mA for 20 minutes. The optimal electrode position and current parameters are determined by using the MIDA head electric field model.
