Perception of Recovery After Pediatric Mild Traumatic Brain Injury Is Influenced by the “Good Old Days” Bias: Tangible Implications for Clinical Practice and Outcomes Research†

Recovery from mild traumatic brain injury (mTBI) is primarily based on the resolution of post-concussive symptoms back to a premorbid level. However, the "good old days" bias means fewer premorbid symptoms are retrospectively recalled, thus skewing the determination of recovery relative to pre-injury. The objectives of this study were to investigate the "good old days" bias in pediatric mTBI and demonstrate the implications of this bias on …
