Study summary

A number of studies from the literature suggest important behavioral, psychosocial, or radiologic changes occur following significant neurologic events or interventions such as stroke, neurosurgery, medications, radiation, systemic therapy, or injury. The purpose of this study is to describe these changes with advanced neurologic imaging and targeted neurologic and neuropsychiatric assessments. This is a non-interventional observational study of minimal risk to participants as there is no medical intervention. The results of this study will be used to inform patients, scientists, and society in the development of future treatments.

Read the detailed description

Functional magnetic resonance imaging (fMRI) and diffusion tensor tractography (DTI) have rapidly expanded since its emergence two decades ago. fMRI is well established as the single most powerful method for detecting changes in neural activity in vivo, albeit indirectly by detection of changes in blood oxygenation level dependent (BOLD) signals that reflect hemodynamic changes subsequent to neural activity. A conventional fMRI experiment involves the comparison of two or more brain states followed by statistical tests to identify which brain regions were involved in a particular task. The identification of patterns of highly correlated low-frequency MRI signals in the resting brain provides a powerful approach to delineate and describe neural circuits, and an unprecedented ability to assess the manner in which distributed regions work together to achieve specific functions. Since the first reports of temporal correlations in BOLD baseline signals, several distinct cortical long-range networks have been identified and characterized in the resting state, including a default mode network. Moreover, observations of altered resting state connectivity in several disorders and as a function of behavior or cognitive skills suggest these correlations reflect an important level of brain organization and may play a fundamental role in the execution and maintenance of various brain functions. DTI is also an exceedingly important imaging modality that has elucidated the neural connectivity inherent between various cortical and subcortical structures. DTI is routinely used and has enhanced our understanding of functional connections between various parts of the brain. Prior to interventions, DTI is commonly obtained, so that interventionists can avoid critical circuitry. There is suggestion that both fMRI and DTI imaging is influenced by organic or interventional variables, however this is understudied. The neuroscientists and clinicians would greatly value information that would expand our working knowledge of the basic neural substrates and functional neural changes that occur in patients organically or after interventions. A non-invasive, non-interventional, observational study is needed to show the changes that happen to patients organically or in standard of care settings. A greater working understanding of the neural connectivity and changes that happen in the brain is of great future benefit to patients, science, and society as well as future therapeutic development such as post-stroke care, rehabilitation, post-traumatic brain injury, or post-treatment care in the brain that has previously been influenced by intervention or disease.

Study population

VUMC adult patients with neurologic disease or patients with neurologic interventions such as neurosurgical procedures or radiation therapy. Men and women of any ethnicity, race or socioeconomic status who meet inclusion criteria will be offered enrollment into the study. Patient will be greater than 18 years of age and meet inclusion and exclusion criteria. Patients eligible for this study will include patients with neurologic events, including but not limited to stroke, depression, infections, psychiatric disease. Intervention is not part of this study, however, patients receiving neurologic interventions, such as neurosurgical procedures or radiation therapy, would be eligible.

Ran from Aug 2020 to primary completion in Feb 2024, 41 months.

Of 26 observational studies under Obsessive-Compulsive Disorder, half reached primary completion within 68 months of starting (the median), counting those still running; a quarter within 41 and three quarters within 84. This study's 41 months is below that.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 6, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
