Frontal iTBS for Impulsivity and Suicidal Ideation in Veterans With Mild Traumatic Brain Injury
What this study is about
The investigators hope to develop a treatment for suicidal ideation (SI), impulsivity and functional impairments (such as difficulties in social and work settings) that occur after a mild traumatic brain injury (mTBI). These conditions have been shown to be linked.
View original scientific description
The investigators hope to develop a treatment for suicidal ideation (SI), impulsivity and functional impairments (such as difficulties in social and work settings) that occur after a mild traumatic brain injury (mTBI). These conditions have been shown to be linked. The investigators are using a high-powered magnetic pulse, called intermittent theta burst stimulation (iTBS) applied to the head to see if it can improve these symptoms. The high-powered magnetic pulse causes certain cells in the brain to activate, which seems to strengthen connections between parts of the brain. The purpose of this research is to gather early information on the safety and effectiveness of iTBS provided to the front of the head for impulsivity, SI and functional deficits after mTBI. The investigators plan to use the data collected in this study to develop larger studies in the future. iTBS is FDA approved, but not for these specific symptoms, or in the specific location the investigators are placing it. The investigators are testing to see if its effective for the above conditions when applied to the front of the head.

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.
