Home-Based Transcranial Direct Current Stimulation (tDCS) for Depression in Multiple Sclerosis (MS)
What this study is about
This project is a where neither patients nor doctors know which treatment is given, sham-controlled, parallel-treatment group$1, randomly assigned controlled trial. We will recruit n=170 people living with MS, who are experiencing an episode of depression in the context of a major depressive episode (MDE).
View original scientific description
This project is a double-blind, sham-controlled, parallel-arm, randomized controlled trial. We will recruit n=170 people living with MS, who are experiencing an episode of depression in the context of a major depressive episode (MDE). Using our remotely supervised (RS) tDCS protocol, enrolled participants will complete 30 days of 30-minute tDCS (2.0, DLPFC left anodal) while listening to mindfulness meditation. Over the course of the study, participants will complete assessments of depression and MS symptoms. Participants will be randomized 1:1 active:sham tDCS.
Interventions
DEVICE
Active tDCS
tDCS is a noninvasive brain stimulation technique that delivers a low-intensity electrical current (2.0 mA) through sponge electrodes placed on the scalp. For Active tDCS, the device is programmed to ramp up to 2.0 mA (for 30 seconds), provide constant current throughout session (29 minutes), and then ramp down (for 30 seconds) at the end.
DEVICE
Sham tDCS
tDCS is a noninvasive brain stimulation technique that delivers a low-intensity electrical current (2.0 mA) through sponge electrodes placed on the scalp. For Sham tDCS (or placebo) the device is programmed to ramp up to 2.0 mA (for 30 seconds) followed by a ramp down (30 seconds), with no current delivery for 28 minutes, and then ramp up (for 30-s) and down (for 30-s) at the end.
Primary outcome measures
Change in Hamilton Depression Rating Scale (HDRS-17)
Time frame: Baseline, Week 8 (End of Intervention)
HDRS-17 is a 17-item assessement of depression symptoms. Each item is rated on a Likert scale; the total score is the sum of responses and ranges from 0-52, with higher scores indicating greater levels of depression. A score of 0-7 is generally accepted to be within the normal range (or in clinical remission), while a score of 20 or higher indicates at least moderate severity.
Change in Hamilton Depression Rating Scale (HDRS-17)
Time frame: Baseline, Month 3
HDRS-17 is a 17-item assessement of depression symptoms. Each item is rated on a Likert scale; the total score is the sum of responses and ranges from 0-52, with higher scores indicating greater levels of depression. A score of 0-7 is generally accepted to be within the normal range (or in clinical remission), while a score of 20 or higher indicates at least moderate severity.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Age: 18-65 years (inclusive)
- Diagnosis: Confirmed diagnosis of multiple sclerosis (MS), including relapsing-remitting or secondary progressive subtypes
- Stable Medications: Stable use of antidepressant and disease-modifying therapies (DMTs) for at least 30 days prior to enrollment
- Stable Disease Activity: Defined as no clinical relapse, no new radiological disease activity, and no recent steroid treatment for at least 30 days prior to enrollment
- Provider Contact: Confirmed access to a local provider that has primary responsibility for the subjects' clinical care, and who is available for contact in case of increased subject risk due to depressive symptoms
- Technical Ability: Ability to use mobile devices and participate in remote, video-supervised sessions
Exclusion criteria
- Neurological or Medical Disorders: History of primary neurological disorder other than MS (e.g., stroke, Parkinson's disease, traumatic brain injury (TBI), intracranial mass, epilepsy, mild cognitive impairment (MCI), dementia), major psychiatric disorders (e.g., bipolar disorder, psychotic disorders), or serious medical conditions (e.g., myocardial infarction, thyroid disease, diabetes with complications, atrial fibrillation)
- Substance Use: Nicotine use (e.g., smoking or vaping) within the past 6 months
- Pregnancy and Breastfeeding: Currently pregnant, planning pregnancy during the study period, or breastfeeding. If able to become pregnant, participants will be required to use medically accepted birth control methods, including hormonal methods (e.g., pills, patches, implants), barrier methods (e.g., condoms or diaphragm with spermicide), intrauterine device (IUD), or abstinence. Participants will be advised not to become pregnant during the study.
- Seizure History: History of seizures or seizure disorder within the past 5 years
- Implanted Devices or Metal Objects: Presence of metal in the head/neck area (excluding dental fillings) or implanted medical devices (e.g., neurostimulators, pacemakers, defibrillators)
- Skin Conditions: Active skin disorders or skin sensitivity near electrode application sites
Where
- New York, New York

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
