Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Before the tACS treatment, a series of cognitive assessments and neuropsychological tests were obtained by a trained investigator to assess baseline. Each assessment will involve a set of assessment tools, the Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog) as the primary outcome measure and various other tasks and questionnaires to measure cognition (including MoCA,MMSE, DS, Stroop test, TMT, BNT-30, VFT, CDT,JLOT. Form H,HVOT), memory (CAVLT, LMT), emotion(HAMA-17,HAMD-14,GDS-30), behavioral and psychological symptoms(NPI), and treatment tolerability. All the tests are conducted in two days. The patient received resting EEG data collection. After the last treatment, the MoCA, and associative memory were obtained, as well as the Global Index of Safety to assess adverse events of the treatment. Patients were instructed to focus their answers on the past 14 days. The patients had also receiving a battery measure of neuropsychological tests, resting EEG. Two months after the last treatment, participants were interviewed to obtain the same assessment as before. They were instructed to focus their answers on the past months.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
transcranial alternating current stimulation-Real
Participants will receive real tACS once daily for 14 days
Transcranial alternating current stimulation
Transcranial alternating current stimulation (tACS) is a non-invasive brain stimulation tool that alters cortical excitability and activity via application of weak alternating currents.
transcranial alternating current stimulation-Sham
Participants will receive sham tACS once daily for 14 days
Sham transcranial alternating current stimulation
In the sham condition, tACS was delivered only during the ramp-up and ramp-down periods (30s); no current was delivered during the 30-minute intervention.
