tDCS Intervention in Breast Cancer Survivors With and Without Obesity Reporting Cognitive Impairment
Sponsor: University of Helsinki
Summary
The goal of this intervention is to investigate whether transcranial Direct Current Stimulation (tDCS) can alleviate Cancer-Related Cognitive Impairment (CRCI) in breast cancer survivors, as measured by changes in brain structures and cognitive performance. To assess the efficacy of tDCS, the investigators will compare outcomes between participants receiving active stimulation and those receiving sham stimulation (a placebo condition where participants believe they are receiving stimulation, but are not). Participants will: * Undergo a baseline MRI session * Receive either active or sham tDCS for six weeks * Undergo a follow-up MRI session * Complete cognitive tests and respond to psychosocial questionnaires before, during, and after the tDCS intervention

Interventions
active tDCS
The anodal electrode will be placed over the left DLPFC (F3), and the cathodal electrode will be placed over the right supraorbital area (FP2). The current will be gradually ramped up to 2mA over 30 seconds, held constant at 2mA for 29 minutes, and then gradually ramped down to 0mA over the final 30 seconds.
sham tDCS
The anodal electrode will be placed over the left DLPFC (F3), and the cathodal electrode will be placed over the right supraorbital area (FP2). The current will be initially ramped up to 2mA over 30 seconds and immediately ramped back down to 0mA.
