Introduction



Dr. Andrea Knight, a pediatric rheumatologist at the Hospital for Sick Children (SickKids), and the University of Toronto, recently won the 2026 Lupus Canada Catalyst Grant for her study, “A New Approach to Functional Brain Imaging in Childhood-Onset Lupus”, which aims to understand what causes cognitive dysfunction in children and adolescents with systemic lupus erythematosus (SLE) using optically pumped magnetoencephalography (OPM-MEG), a noninvasive neuroimaging technique. The Lupus Canada Catalyst Grant provides one year of funding to researchers to support innovative research.


Dr. Knight is well recognized in the field of lupus, and was previously awarded:

• Chair for the Canada Research Tier 2 for Mental Health in Childhood Chronic Disease at the Canada Institute of Health Research Lupus Research

• Alliance Career Development Award to Promote Diversity in Lupus Research

• Lupus Foundation of America Mary Betty Stevens MD Young Investigator Prize

• Edmond L Dubois Memorial Lectureship and Investigator Award from the Rheumatology Research Foundation

A New Approach



OPM-MEG is a new non-invasive neuroimaging technology that uses a wearable helmet to measure the tiny magnetic fields generated by brain electrical activity with millisecond precision. Unlike traditional tracking systems, like Superconducting Quantum Interference Devices (SQUID-MEG) or electroencephalography, OPM-MEG tracks magnetic fields using laser-based quantum technology and can operate at room temperature. The OPM-MEG is optimal for adolescent research because it employs an adjustable 3-D-printed wearable cap, allowing patients a wide range of movement.


Dr. Knight's study plans to use OPM-MEG to track differences in brain activity between lupus and non-lupus patients in conjunction with cognitive and blood biomarkers to clarify the cognitive differences between young lupus patients and other individuals. Ultimately, the goal is to “develop and test systematic approaches utilizing multi-level biomarkers for early detection and targeted, individualized treatment of neuropsychiatric disorders in SLE.”





Why It Matters: An Underrecognized Field



Though they only consist of 10-20% of all lupus diagnoses, young children and adolescents tend to experience more aggressive lupus. And though symptoms such as fatigue, emotional functioning challenges, and concentration difficulties can negatively affect a patient's mental health during critical stages of development, these issues are often ignored.


Additionally, children may have an increased risk of declining cognitive abilities due to SLE-related brain inflammation. Dr Knight reports that she often comes across “many young people with lupus who struggle with fatigue, concentration, and emotional functioning, impacting their schooling and day-to-day life. These issues are often under-recognized.”, and hopes that her research can gather foundational data in a non-invasive way to understand why cognitive dysfunction occurs.


In time, she aims to translate this data into meaningful improvements in care. Similarly, Leanne Mielczarek, CEO of Lupus Canada, believes that Dr. Knight's research has the potential to inform more effective interventions and support strategies by advancing our understanding of how lupus affects cognitive function at an early age. Mielczarek hopes that Dr. Knight's research will alleviate the struggles that children and adolescents living with lupus face.





Conclusion



Although the intersection between psychiatric health and lupus has been widely ignored, Dr. Knight paves the way for new research and developments using innovative non-invasive technologies such as OPM-MEG. She hopes her research will improve quality of life for lupus patients and provide clarity on future treatment plans.
