Effectiveness of Personalized Alternating Current Stimulation for Treating Cognitive Impairment in CNS Demyelination Patients

Using the advanced Neuroelectrics StarStim 32 device from Spain, individualized imaging modeling systems are employed to precisely target the frontal and parietal cortex. Personalized EEG-guided electrical stimulation protocols are selected. The stimulation parameters are as follows: a current intensity of 2 mA, a duration of 21 minutes per session for one time with EEG monitoring conducted before and after electrical stimulation.

Sham stimulation is performed using the same device and procedures as the neuromodulation group. The stimulator automatically shuts off after 30 seconds, while maintaining the device's connection. This design creates an initial sensation similar to actual stimulation while preserving the double-blind nature of the study.
