Single Session Personalized Aperiodic Transcranial Alternating Current Stimulation (PandA-tACS) for Antenatal Depression (PandA)

1 września 2026 zaktualizowane przez: University of North Carolina, Chapel Hill

Single Session Personalized Aperiodic Transcranial Alternating Current Stimulation (PandA-tACS) for Antenatal Depression: A Randomized, Sham-Controlled Trial (R61 Phase)

The purpose of this pilot trial is to primarily assess safety, feasibility, and tolerability of PandA-tACS in antenatal depression and determine whether a single PandA-tACS session produces greater left dlPFC aperiodic slope flattening (reduction) from pre- to post-stimulation than IAF-tACS and sham.

Szczegółowy opis

The purpose of this study is to evaluate the safety, feasibility, tolerability, and brain effects of a single session of a personalized form of non-invasive brain stimulation called PandA-tACS in individuals with antenatal depression. PandA-tACS uses each participant's own EEG activity to create an individualized stimulation waveform. Participants will be females aged 18-45 years who are 14-32 weeks pregnant with a viable, low-risk singleton pregnancy and meet criteria for unipolar, non-psychotic major depressive disorder. Participants must be at low suicide risk, and be able to complete study procedures.

Participants will complete screening, informed consent, clinical assessments, pregnancy safety review, and high-density EEG recordings. Eligible participants will attend one in-person stimulation visit and will be randomized to receive PandA-tACS, individualized alpha-frequency tACS, or sham stimulation. Stimulation will be delivered through scalp electrodes while participants are monitored by trained study staff. EEG, symptom ratings, blood pressure, pre-natal safety checks, and adverse event monitoring will be completed before and/or after stimulation. Optional MRI may be completed for electric-field modeling. Pregnancy and birth outcomes will be reviewed through the medical record.

Pozorny komparator: Inactive Sham (placebo)
Participants will receive sham tACS. Sham stimulation mimics all procedures used in active stimulation.
Participants will be fitted with the same electrode setup and receive sham (placebo) tACS delivered using the neuroConn DC Stimulator MC.
Aktywny komparator: Active IAF-tACS: Experimental Arm
Participants will receive active IAF-tACS delivered at the participant's individual alpha frequency, as measured by EEG. 2mA will be delivered at Cz, and 1 mA (antiphase) split between F3/F4 (in phase). IAF-tACS is delivered in 4 x blocks of 10 min, separated by 2 min HD-EEG.
Participants will be fitted with the same electrode setup and receive IAF-tACS delivered using the neuroConn DC Stimulator MC.
Eksperymentalny: Active PandA-tACS: Experimental Arm
Participants will receive active PandA-tACS delivered with the participant's flatter aperiodic slope, as measured by EEG. 2mA will be delivered at Cz, and 1 mA (antiphase) split between F3/F4 (in phase). PandA-tACS is delivered in 4 x blocks of 10 min, separated by 2 min HD-EEG.
