Brief summary: The goal of this clinical trial is to test a new brain stimulation treatment target for individuals with depression plus at least one additional psychiatric disorder. The main question is to understand the safety profile of a non-invasive form of brain stimulation called accelerated intermittent theta burst stimulation when it is targeting the posterior parietal cortex. Additional questions focus on whether this stimulation improves symptoms of depression and other psychiatric disorders as well as whether this stimulation changes brain function.

Detailed description: Psychiatric disorders are often studied individually. However, up to half of individuals who meet criteria for one psychiatric disorder also meet criteria for another. These individuals are difficult to diagnose and treat. Relative to those with one disorder, individuals with two or more have worse treatment outcomes, more functional impairment, and a greater risk of premature death.

Neuromodulation treatments like transcranial magnetic stimulation (TMS) work when routine psychotherapy and medications have not worked, but they typically target one disorder at a time. In fact, the TMS field is largely focused on strategies to make TMS more precise by targeting individual symptoms within a diagnosis. This strategy is important, but it may be difficult to scale and optimize in the setting of real-world psychiatric comorbidity. For example, there are 227 possible ways to meet criteria for major depressive disorder, complicating precision TMS strategies for individuals with or without comorbid disorders.

In this study, the investigators are moving in a different direction by targeting the brain network shared across psychiatric disorders in treatment-seeking individuals with more than one psychiatric disorder. This approach is based upon prior work. In a 2023 Nature Human Behavior study, the investigators analyzed four independent datasets with coordinate and lesion network mapping to test for a brain network shared across psychiatric disorders. They found that atrophy coordinates across six psychiatric disorders (193 studies) mapped to a common brain network defined by positive connectivity to the anterior cingulate and insula, and by negative connectivity to posterior parietal and lateral occipital cortices. The investigators verified that this transdiagnostic network was robust to leave-one-diagnosis-out cross validation and specific to atrophy coordinates from psychiatric versus neurodegenerative disorders (72 studies). Lesion-induced damage to this network correlated with the number of post-lesion psychiatric diagnoses in an independent dataset (194 patients). The transdiagnostic network also aligned with neurosurgical ablation targets for psychiatric disorders (4 targets), suggesting possible therapeutic relevance and generating testable hypotheses for neuromodulation. Importantly, the candidate TMS target that emerges from this transdiagnostic network is also a critical node of the convergent depression network that was derived across 14 independent datasets. This target has not been robustly tested for major depressive disorder (MDD) or transdiagnostic symptoms.

In this open-label pilot trial, the investigators will test the hypothesis that modulating the transdiagnostic network with transcranial magnetic stimulation (TMS) will be safe and tolerable. Secondary outcomes will assess changes in the cumulative burden of psychopathology in individuals with MDD plus at least one additional psychiatric disorder. This approach is novel in three important ways: 1) This study will enroll, not exclude, individuals with multiple psychiatric illnesses. Most clinical trials selectively enroll individuals with a single diagnosis, a strategy that does not generalize to real-world settings where psychiatric comorbidity is common and difficult to treat. 2) The transdiagnostic target was validated with causal sources of information (i.e., brain lesions, neurosurgical ablation). In other words, this study will optimize the "where to stimulate" factor. TMS targets are usually derived from functional neuroimaging studies that identify correlates of illness. These correlates could cause, compensate for, or be epiphenomena of treatment or other variables, an interpretation that matters for TMS. 3) The investigators will use the most rapid-acting and robust TMS protocol. In other words, they will optimize the "how to stimulate" factor. Conventional TMS protocols require scalp-targeted treatments delivered weekdays for 6-8 weeks. By contrast, the accelerated intermittent theta burst (iTBS) protocol in this study is adapted from Stanford Accelerated Intelligent Neuromodulation Therapy (SAINT), which consists of MRI-guided treatment delivered 10 times a day for 5 days.
