Meier Laboratory

The Meier Lab seeks to identify mechanisms of the acute and chronic effects of mild traumatic brain injury, including sport-related concussion. Using a variety of approaches鈥攊ncluding advanced magnetic resonance metrics (e.g., fMRI, diffusion imaging, structural imaging), blood-based biomarkers, and clinical/behavioral testing鈥攚e look to answer questions such as: how long does it take the brain to recover following an acute mTBI, what are the physiological mechanisms associated with prolonged recovery following mTBI, and what are the cumulative effects of repetitive sport-related concussion on the brain?

Research Areas

Cumulative Effects of Concussion and Contact-Sport Participation

ACC connectivity and KYNA/QUIN relationship significantly different in persons with prior concussion history

The Meier Lab is actively involved in determining the effects, if any, of repeat concussion and contact-sport participation on brain function and structure. Our group was among the first to demonstrate that subtle differences in brain structure (e.g., smaller volumes) and function鈥攕uch as altered resting state connectivity, more psychological symptoms鈥攁re present in otherwise healthy college-aged athletes with prior concussion compared to athletes without concussion. Similar associations have also been observed in athletes with extensive contact sport experience compared to those with no contact sport experience. These results were limited to football players in relatively small sample sizes. One of our actively funded projects (R01NS102225; PI: Meier) involves replicating these findings and extending them to non-football and female athletes. This project will determine the relationship amongst concussion/contact sport history, brain structure and function, and blood-based biomarkers of a common immunoregulatory pathway that has been implicated in a variety of psychiatric and neurodegenerative diseases.

Blood-Biomarkers in mTBI and Concussion

Concussion Biomarkers

The Meier Lab is actively investigating the potential utility of blood-based biomarkers in concussion and mTBI. Blood-based biomarkers have promise as objective markers to supplement current clinical practice for decisions regarding injury diagnosis and identifying individuals at risk for prolonged recovery. For example, we have demonstrated that brain-injury markers, such as GFAP, are elevated following sport-related concussion and improve the discrimination of concussed athletes compared to discrimination using symptoms alone. In addition, we have shown that inflammatory markers, while not specific to concussion, are predictive of symptom-duration following concussion. Ongoing work funded by the NIH continues to identify novel markers and investigate the utility of these markers in other cohorts, such as women and military service academy members (R21NS118169; R21NS099789; PI: Meier).

In addition to their potential clinical utility, blood-based biomarkers can also help identify potential physiological mechanisms that put individuals at risk for developing negative outcomes following concussion and mTBI. Several of our recent and ongoing projects have focused on blood levels of a common immunoregulatory pathway known as the kynurenine pathway. While this pathway has been linked with a variety of psychiatric and neurodegenerative diseases, its role in mTBI has been underappreciated. The Meier Lab is investigating the association of blood levels of neuroactive kynurenine pathway metabolites with psychiatric sequelae observed acutely and chronically following TBI (R21NS099789; R01NS102225; PI: Meier).

Neuroimaging of mTBI and Concussion

Neuroimaging Concussion

Neuroimaging currently provides the most direct approach to studying the effects of TBI on the brain. The Meier Lab uses advanced MRI metrics—including task-based fMRI, resting state fMRI, diffusion MRI, arterial spin labeling, and structural MRI—to characterize the acute effects of mTBI and sport-related concussion on brain function and structure, as well as the time course of their recovery. Given our involvement in various MRI studies of concussion across several cohorts, we are also focused on leveraging and harmonizing MRI data from multiple prior projects to facilitate analyses of sport-related concussion on a scale that may not be feasible with single-site studies—e.g., potential moderating effects of sex.

The CARE Consortium is a large, multi-site effort focused on characterizing the acute, intermediate, and cumulative/chronic effects of concussion and head impact exposure in NCAA athletes and military service academy members using head impact sensors, advanced MRI, blood-based biomarkers and genetics, and clinical testing, and the Meier Lab is critically involved in the blood and MRI biomarker work of the CARE Consortium Studies, including CARE 1.0, CARE 2.0, and CARE-SALTOS Integrated.
