Treatment for mild concussion in the past has been limited to bed rest. Previous studies have noted that bed rest following a concussion does not improve recovery time and, if continued for too long, can negatively impact recovery. Some pilot projects have reported promising findings such as decreased 30-day mortality with progesterone. Through a meta-analysis of non-surgical interventions following a mild TBI, Nygren-de Boussard et al. found that there are poor randomized controlled trials or comparison groups to indicate any intervention can provide therapeutic benefit. Furthermore, evidence supports a more individualized approach when treating post-concussive symptoms.
