Brief Summary
Depression is the leading cause of disability worldwide. Because a significant number of people with depression do not respond to medication or therapy, alternative treatment options are greatly needed. Recent research has focused on brain stimulation methods due to their therapeutic utility for treating depression. Yet, current brain stimulation methods have drawbacks, including invasive surgery and limited precision in targeting specific areas. A novel brain stimulation method, transcranial ultrasound (TUS), is noninvasive, has greater spatial precision than most existing methods, and is proven safe for humans. TUS has been found to increase positive mood in chronic pain patients. In a double blind study, TUS increased positive mood in over 140 healthy undergraduates at the University of Arizona. Despite evidence that TUS can increase positive mood in humans, it has yet to be investigated whether TUS can increase positive mood in humans who are experiencing chronic low mood or depression. The present study will, for the first time, examine whether TUS can improve depressive symptoms. Twenty to thirty participants with mild to moderate depressive symptoms (Beck Depression Inventory Score between 10 and 25) will be randomly assigned to a TUS sham or TUS activation condition. In the TUS activation condition, TUS will be used to stimulate the right fronto-temporal area, which has previously been shown to increase positive mood. Participants in the TUS sham condition will not receive any brain stimulation. Participants will attend five sessions within seven days or ten sessions within fourteen days. At each session, in addition to brain stimulation, self-reported mood and depressive symptoms will be recorded. Furthermore, the investigators will use electroencephalogram (EEG) to record changes in brain electrical signals during TUS stimulation. Based on prior research, the investigators predict that mood will increase and depressive symptoms will decrease with TUS stimulation.

Outcome Measures
Primary Outcomes (1)
Depressive Symptoms Assessed With the Beck Depression Inventory-II
The Beck Depression Inventory-II (BDI-II) is one of the most widely used self-report measures for assessing depression. It includes 21 self-report items. Scores range from 0 to 63, and higher scores indicate higher levels of depressive symptoms. In this study, the BDI-II was used to monitor depressive symptoms each day. The outcome is the change in BDI-II score as measured by BDI-II on Day 5 minus BDI-II on Day 1.
Once on day 1 & day 5
Secondary Outcomes (3)
Rumination Symptoms Assessed With the Ruminative Responses Scale
Once on day 1 & 5
Worry Symptoms Assessed With the Penn State Worry Questionnaire
Once on day 1 & day 5
Anxiety Symptoms Assessed With the Overall Anxiety Severity and Impairment Scale
Once on day 1 & day 5
Study Arms (2)
Transcranial Ultrasound Power
ACTIVE COMPARATORTranscranial Ultrasound Power
Transcranial Ultrasound Sham
SHAM COMPARATORTranscranial Ultrasound Sham. Unknown to both participants and experimenters, the ultrasound will not stimulate.
Interventions
Transcranial ultrasound will be to stimulate at the right fronto-temporal cortex. 30 seconds of stimulation at 500 kHZ with duty cycle 0.24% and pulse rate frequency at 40 Hz.
Transcranial ultrasound will be used without power for a "sham" condition.
Eligibility Criteria
You may qualify if:
- Beck Depression Inventory score between 10 and 25
You may not qualify if:
- left-handedness
- prior serious head-related injury
- any medical condition that would impact EEG profiles
- chronic migraines or other severe headaches
- pregnancy
- lack of proficiency in English
- lack of secure housing
- current confounding treatment (including any psychotropic medication or psychotherapy)
- current active suicidal potential necessitating immediate treatment, as such participants will be referred for immediate treatment.
