EEG Prediction and Clinical Efficacy of tDCS in Major Depression (DM-TDCS-PREDIC)

3. juli 2026 oppdatert av: Ionclinics & Deionic SL

Clinical Efficacy of tDCS in Major Depression: A Controlled Clinical Trial and Analysis of Electrophysiological Biomarker Predictors

The purpose of this randomized controlled trial is to investigate the non-inferiority, and possible superiority, of a high-dose home-based tDCS protocol compared with a conventional home-based protocol, and to assess its cost-effectiveness, in patients with major depression.

As a secondary aim, we aim to assess the predictive value of baseline EEG for clinical response to high-dose home-based tDCS treatment in patients with major depression.

  • Demonstrate the ability to apply home-based tDCS appropriately, either independently or with the help of a carer.
  • Have access to an electronic device with a camera to enable monitoring of the intervention, as well as to contact the participant.
  • Have the ability and willingness to commit to the study team to complete all phases of the study.
  • Volunteer to participate and sign the specific informed consent form for this study.

Exclusion Criteria:

  • Patients with a current manic episode as determined by the Young Mania Rating Scale (YMRS), or a psychotic episode as defined by the MINI scale.
  • Patients who answer 'yes' to questions 4, 5 or 6 of the Columbia Suicide Severity Rating Scale (C-SSRS), a risk assessment and identification tool.

  • Any previous hospitalisation for suicidal behaviour.
  • Presenting with current chronic or severe insomnia (< 4 hours' sleep per night) or sleep apnoea.
  • Presence of any structural lesion (e.g., any structural neurological condition or more subcortical lesions than would be expected for their age, or having suffered a stroke affecting the stimulated area or connected areas) or any other clinically significant abnormality that may affect safety, participation in the study, or confound the interpretation of study results, as determined by the investigator.
  • History or presence of any other condition or comorbidity associated with TDM: cardiac or neurological conditions, cognitive impairment.
  • History of or current diagnosis of any other mental disorder: obsessive-compulsive disorder, bipolar disorder (type 1 or 2), anxiety disorder, agoraphobia, eating disorders, personality disorders.

Intervensjon / Behandling
Eksperimentell: High-dose home-tDCS
Enhet: High-dose home-tDCS
Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique in which a weak direct current (2 mA) is applied to the scalp via electrodes. The anode will be applied to F3 (left dorsolateral prefrontal region) and the cathode to F8 (right supraorbital region). The application of tDCS will be carried out at home in this group. Each session will consist of 20 minutes of stimulation. Dose: 3 weeks, daily. (1) 1st week - 3 times per day; (2) 2nd Week - 2 times per day; (3) 3rd week - 1 time per day (total of 42 sessions).
Aktiv komparator: Conventional home-tDCS
Enhet: Conventional home-tDCS
Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique in which a weak direct current (2 mA) is applied to the scalp via electrodes. The anode will be applied to F3 (left dorsolateral prefrontal region) and the cathode to F4 (left dorsolateral prefrontal region), described by Woodham et al., 2024. The application of tDCS will be carried out at home in this group. Each session will consist of 30 minutes of stimulation. Dose: (1) Week 1 to 3: 1ss/day for 5 days; (2) Week 4 to 10: 1ss/day for 3 days (total 36 sessions).
