Does SARS-CoV-2 Infection Increase Risk of Neuropsychiatric and Related Conditions? Findings from Difference-in-Differences Analyses.

The COVID-19 pandemic has been associated with increased neuropsychiatric conditions in children and youths, with evidence suggesting that SARS-CoV-2 infection may contribute additional risks beyond pandemic stressors. This study aimed to assess the full spectrum of neuropsychiatric conditions in COVID-19 positive children (ages 5-12) and youths (ages 12-20) compared to a matched COVID-19 negative cohort, accounting for factors influencing infection risk. Using EHR data from 25 institutions in the RECOVER program, we conducted a retrospective analysis of 326,074 COVID-19 positive and 887,314 negative participants matched for risk factors and stratified by age. Neuropsychiatric outcomes were examined 28 to 179 days post-infection or negative test between March 2020 and December 2022. SARS-CoV-2 positivity was confirmed via PCR, serology, or antigen tests, while negativity required negative test results and no related diagnoses. Risk differences revealed higher frequencies of neuropsychiatric conditions in the COVID-19 positive cohort. Children faced increased risks for anxiety, OCD, ADHD, autism, and other conditions, while youths exhibited elevated risks for anxiety, suicidality, depression, and related symptoms. These findings highlight SARS-CoV-2 infection as a potential contributor to neuropsychiatric risks, emphasizing the importance of research into tailored treatments and preventive strategies for affected individuals.
