Demographic-Dependent Risk of Developing Severe Novel Psychiatric Disorders after Concussion

Current guidelines for patients experiencing a concussion or mild traumatic brain injury (mTBI) often focus on conservative care and observation. However, mTBI may increase the risk of severe novel psychiatric disorders (NPDs) within 180 days, and long-term management of mTBI should include psychiatric evaluation in patient populations. Retrospective cohort analysis was conducted using 8 years of the Nationwide Readmission Database. All individuals who were admitted for concussion and were readmitted within 180 days were queried. This cohort was then subdivided based on age, sex, and whether they experienced loss of consciousness (LOC) to control for demographic-dependent confounding. A binary decision tree provided recommendations for patients who may be at risk of developing severe NPDs. Analysis included 12,080 patients who experienced concussion. Males and females with LOC had higher rates of depression in all age quartiles within 180 days (
