Brief Summary
The purpose of this study is to determine whether changes in sleep consolidation occur during home-based transcranial direct current stimulation (tDCS) in adults with moderate depression and whether these changes are temporally associated with improvements in depressive symptoms.

Outcome Measures
Primary Outcomes (1)
Change in sleep efficiency
Sleep efficiency (SE) is the percentage of time spent asleep while in bed. A healthy, normal efficiency is 85% or higher, with 90% or more considered very good. Low efficiency can indicate poor sleep quality.
Baseline, Post-Intervention (Week 5)
Secondary Outcomes (7)
Change in wake after sleep onset (WASO)
Baseline, Post-Intervention (Week 5)
Change in night-to-night variability in sleep efficiency
Baseline, Post-Intervention (Week 5)
Change in total sleep time
Baseline, Post-Intervention (Week 5)
Change in sleep latency
Baseline, Post-Intervention (Week 5)
Change in Montgomery-Åsberg Depression Rating Scale (MADRS-S) score
Baseline, Final Follow-Up Study Visit (Month 2)
- +2 more secondary outcomes
Study Arms (1)
Active transcranial direct current stimulation (tDCS)
EXPERIMENTALParticipants will complete a 20-session course of home-based left dorsolateral prefrontal cortex (DLPFC) transcranial direct current stimulation (tDCS) (2.0 mA, 30 minutes per session).
Interventions
Transcranial direct current stimulation delivers a gentle, low-intensity electrical current. The tDCS device is programmed to ramp up to 2.0 mA (for 30 seconds), deliver constant current throughout the session (29 minutes), and then ramp down (for 30 seconds) at the end of the session.
Eligibility Criteria
You may qualify if:
- Ability to read and understand study materials in English, as demonstrated by a standard score \>85 on the WRAT-5 Reading Recognition Subtest
- MADRS-S ≥18 during screening
- Confirmed diagnosis of MDD, based on clinician interview
- If taking antidepressant medication, the dose must be stable for at least 30 days prior to pre-screening.
- 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 OR confirmed acknowledgement and identification of local resources.
- Able to provide informed consent and comply with study procedures.
- Access to a quiet space suitable for home-based tDCS stimulation sessions.
You may not qualify if:
- Current major medical condition that, in the opinion of the study clinician, would interfere with study participation, safety, or interpretation of study outcomes.
- Current or past bipolar disorder, psychotic disorder, or current (past 6 months) alcohol or substance use disorder, as determined by clinician assessment at screening.
- Clinically significant suicidal ideation or behavior, based on clinician assessment and the Columbia-Suicide Severity Rating Scale (C-SSRS).
- Use of prescription or over-the-counter sleep-promoting medications or initiation of behavioral interventions specifically targeting sleep in the past 30 days from pre-screening.
- History of seizure disorder or epilepsy.
- Presence of an active implanted medical device above the neck (e.g., deep brain stimulator, cochlear implant) or non-MRI-compatible metallic implants in the head or neck region.
- Current use of prescription or over-the-counter sleep medications, or active participation in any behavioral or pharmacologic treatment specifically targeting sleep.
- Pregnancy and Breastfeeding: Currently pregnant, planning pregnancy during the study period, or breastfeeding o 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.
