NCT06053775

Brief Summary

The goal of this clinical trial is to test a home-delivered intervention that combines Non-Invasive Brain Stimulation techniques (transcranial direct and alternating current stimulation -tDCS and tACS-) and Online Cognitive Training (OCT) to treat depressive symptomatology and cognitive decline associated with breast cancer. The main questions aims to be answered are:

  • To analyze the efficacy and feasibility of the intervention to treat depressive symptomatology.
  • To analyze the efficacy and feasibility of the intervention to treat cognitive decline.
  • To evaluate the medium and long-term effects (1, 3 and 6 months) of intervention. An OCT program and a portable wireless tDCS/tACS system will be used to perform the intervention at home. Patients will be divided into four treatment groups, depending on whether they will receive the OCT applied independently or combined with tDCS/tACS active or sham. In addition, saliva samples will be collected to identify bomarkers predictive of treatment efficacy.

Secondary Outcomes (2)

  • Patient Reported Outcomes Measurement Information System (PROMIS) Cognitive Function 8a

Study Arms (4)

Online Cognitive Training

ACTIVE COMPARATOR

15 sessions of 20 minutes each one.Training will focus on the stimulation of several cognitive functions (attention, memory and learning, language, executive functions,processing speed, etc) through different exercises. The sessions will be adjusted to the individual performance level. The participant will perform these exercises from their computer or tablet, through the NeuronUp2GO platform, and the researcher will have access to all the session data.

Device: Online Cognitive Training

Transcranial Direct Current Stimulation

EXPERIMENTAL

tDCS: 15 daily sessions targeting left DLPFC (anode: F3, cathode: Fp2) Current intensity will be set at 2mA and will be applied for 20 minutes, with 15-second ramps up and down at the beginning and end of the stimulation period. During the session, the participant will be performing the OCT.

Device: Transcranial Direct Current StimulationDevice: Online Cognitive Training

Transcranial Alternating Current Stimulation

EXPERIMENTAL

tACS: 15 daily sessions targeting left DLPFC (anodes: F3, F4; frequency: 4Hz -theta-tACS-). Current intensity will be set at 2mA and will be applied for 20 minutes, with 15-second ramps up and down at the beginning and end of the stimulation period. Participant will be performing the OCT during stimulation.

Device: Transcranial Alternating Current StimulationDevice: Online Cognitive Training

tES sham

SHAM COMPARATOR

15 sessions of sham stimulation for 20 minutes, acting as a placebo control group. The electrode montage will be the same as that used in the active neuromodulation conditions: tDCS for half of the participants and tACS for the other half. In this sham stimulation condition, the current will only be delivered for a 15 seconds, at the ramp-up and ramp-down times at the beginning and end of the session. The OCT will also be the same as those performed by participants in the other groups

Masking Details
In this study, a double-blind design will be used, since the device used for the tDCS/tACS intervention allows for total blinding. The patient and the researchers involved in treatment will be blinded to the group of treatment (except for the OCT group). Evaluation and data analysis will be blinded to group assignment until the participant has completed the study. Only the members of the research team in charge of generating the randomization list will have access to the patient's intervention status.
