What is the purpose of this trial?

This trial explores a combination treatment for individuals experiencing attention issues after a mild traumatic brain injury (mTBI), with or without PTSD. It combines computer-based attention training (APT) and magnetic stimulation (iTBS, or Intermittent Theta Burst Stimulation) to evaluate their effectiveness in improving attention problems. Participants will join one of four groups, each testing different combinations of these treatments to determine the most effective approach. Eligible participants have experienced mTBI for at least three months and face attention challenges in daily life. As an unphased trial, this study provides a unique opportunity to contribute to innovative research that could enhance attention treatments for mTBI patients.

Will I have to stop taking my current medications?

The trial requires that you stop taking certain medications, such as CNS stimulants, during participation. If your mental health medication dosage has changed in the last 30 days, you may not be eligible. Please consult with the trial team for specific guidance on your medications.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that Attention Process Training (APT) is safe and well-tolerated. It improves attention skills after brain injuries, such as concussions, without causing significant side effects.

Intermittent theta burst stimulation (iTBS) is also safe. It effectively treats conditions like PTSD and depression by using short magnetic pulses to stimulate the brain. Studies report no major safety concerns, and participants usually handle the treatment well.

Both APT and iTBS have strong safety records. For those considering joining a trial, these treatments have been studied and found to be safe. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments because they combine neuromodulation and cognitive training to tackle concussion and PTSD in a new way. Unlike standard treatments that often focus on medication or traditional therapy, this approach uses intermittent theta-burst stimulation (iTBS) targeting the brain's dorsolateral prefrontal cortex, potentially enhancing brain plasticity and cognitive function. Additionally, the Attention Process Training (APT) program offers a novel computer-based cognitive training experience. Together, these treatments could offer faster and more effective relief from symptoms by directly engaging and retraining the brain's pathways.

What evidence suggests that this trial's treatments could be effective for concussion and PTSD?

Research has shown that both APT (Attention Process Training) and iTBS (intermittent theta-burst stimulation) hold promise for alleviating symptoms of mild traumatic brain injury (mTBI) and PTSD (post-traumatic stress disorder). APT has successfully improved attention and cognitive skills in individuals with brain injuries, regardless of the injury's severity or timing. iTBS, meanwhile, quickly alleviates PTSD symptoms and has demonstrated positive effects on depression. In this trial, participants will be assigned to different treatment arms to evaluate these therapies' effects. Some will receive real APT combined with real iTBS, while others will receive placebo versions of one or both treatments. Early evidence suggests that combining these therapies could significantly enhance attention and cognitive skills. ^{3 6 7 8 9}

Trial Overview

The study tests the combined effect of attention processing training (APT) with intermittent theta burst stimulation (iTBS), against placebos for each treatment. It aims to assess improvements in attention among those with mTBI plus PTSD and understand changes in their neurocognitive systems.

How Is the Trial Designed?

Group I: real APT+ real iTBS Experimental Treatment 2 Interventions

real APT+ real iTBS included 30 1-hour treatment sessions will be provided 3/week. Sessions will be conducted for 10 weeks. APT-III is a computer based cognitive training program. iTMS will be applied at 5Hz rate; each burst consists of 3 pulses delivered at 50Hz rate. The bursts are applied for 2s with 8s inter-burst-intervals, for a total of 600 pulses. The total stimulation time per session is approximately 192s (\~ 3 minutes). Participants randomized to active iTBS will receive stimulation at the right dorsolateral prefrontal cortex at 80% active motor threshold .

Group II: placebo APT+ real iTBS Active Control 2 Interventions

30 1-hour treatment sessions will be provided 3/week. Sessions will be conducted for 10 weeks. Placebo APT-III is a computer based active control cognitive training program. Bursts of TMS pulses will be applied at 5Hz rate; each burst consists of 3 pulses delivered at 50Hz rate. The bursts are applied for 2s with 8s inter-burst-intervals, for a total of 600 pulses. The total stimulation time per session is approximately 192s (\~ 3 minutes). Participants randomized to active iTBS will receive stimulation at the right DLPFC at 80% active motor threshold .

Group III: real APT + placebo iTBS Active Control 2 Interventions

30 1-hour treatment sessions will be provided 3/week. Sessions will be conducted for 10 weeks. APT-III is a computer based cognitive training program. Participants randomized to placebo iTBS will not receive any iTBS stimulation.

Group IV: placebo APT+ placebo iTBS Active Control 2 Interventions

30 1-hour treatment sessions will be provided 3/week. Sessions will be conducted for 10 weeks. Placebo APT-III is a computer based active control cognitive training program. Participants randomized to placebo iTBS will not receive any iTBS stimulation.
