tDCS for Late-Life Depression
High-Dose Spaced Bilateral tDCS for Late-Life Depression: Open-Label Pilot Study
The purpose of this research study is to determine the effectiveness of Transcranial direct current stimulation (tDCS) therapy in the treatment of participants with Late-life depression (LLD).
The study will evaluate feasibility, safety, and tolerability of high-dose (6mA) bilateral tDCS delivered as three daily sessions, 3 times a week, for 3 weeks in older adults (60 y/o and older) with late-life depression.

Beskrivelse
Inclusion Criteria:
Participants must meet all of the following criteria:
- age 60 years or older;
- diagnosis of unipolar major depressive disorder according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), confirmed by the Mini International Neuropsychiatric Interview (MINI);
- score of 17 or higher on the 17-item Hamilton Depression Rating Scale (HDRS-17) at screening;
- stable antidepressant regimen for at least four weeks prior to enrollment, if applicable;
- capacity to provide informed consent;
- Clinical Dementia Rating scale of 0 or 0.5.
Exclusion Criteria:
Participants meeting any of the following criteria will be excluded:
- contraindications to tDCS including metallic cranial implants, skin conditions at electrode sites (eczema, open wounds, burns, lesions), or history of adverse reaction to tDCS;
- contraindications to magnetic resonance imaging (MRI) including pacemaker, cochlear implants, ferromagnetic implants, or claustrophobia;
- history of seizures or epilepsy;
- bipolar disorder, psychotic disorders, or severe personality disorder;
- dementia or MoCA score below 17;
- substance use disorder within the past six months;
- neuromodulation treatment including electroconvulsive therapy (ECT), transcranial magnetic stimulation (TMS), tDCS, or vagus nerve stimulation (VNS) within the past six months;
- active suicidal ideation with plan or intent requiring a higher level of care;
- concurrent use of medications that substantially lower seizure threshold;
- pregnancy.

Tidsramme |
|---|---|---|
|
Target engagement
Tidsramme: 6 weeks
|
Resting-state fMRI measures functional connectivity between the DLPFC and subgenual anterior cingulate cortex (sgACC). The DLPFC-sgACC connectivity is a biomarker of depression that predicts treatment response to neuromodulation. Target engagement would be a significant change in DLPFC-sgACC connectivity. |
6 weeks

Clinical - HDRS-17
Tidsramme: 6 weeks
|
Clinical outcomes are assessed using the HDRS-17 at baseline, weeks 1-5, and week 6.
Response is defined as ≥50% reduction in HDRS-17 from baseline.
Remission is defined as HDRS-17 ≤7.

Correlation of Stimulation Dose With Change in HDRS 17 Scores
Tidsramme: 6 weeks
|
Exploratory dose-response analyses will examine correlations between the device stimulation and the changes in clinical outcomes (HDRS-17). This is assessed by correlating achieved baseline E-field (Structural MRI (T1- and T2-weighted) values) and changes in clinical outcomes measured by Hamilton Depression Rating Scale-17 item (HDRS-17). Change in HDRS 17 is defined as the difference between baseline and post-treatment scores at 6 weeks. Correlation analyses (Pearson or Spearman coefficients) are used to quantify the relationship. |
