Use of general practice before and after mild traumatic brain injury: a nationwide population-based cohort study in Denmark

摘要

ObjectivesTraumatic brain injury (TBI) is commonly seen in the emergency department (ED). Approximately 85%–90% of TBIs are mild (mTBI). Some cause symptoms such as headache, dizziness, anxiety, blurred vision, insomnia and concentration difficulties, collectively known as postconcussion syndrome (PCS). Some studies suggest that recovery from mTBI is complete. Others find that symptoms persist for months, even years. The aim of this study was to describe the use of general practice, before and after mTBI, as a proxy for symptoms in a large cohort.
