There are numerous possible effects of a Traumatic Brain Injury (TBI). Researchers have examined the relationship between certain demographic characteristics like gender, age, and psychiatric history and post-injury symptoms. They have not explored the relationship between pre-injury resilience and mood and post-injury characteristics. Some researchers think that euthymic mood and high resilience protect against certain post-concussive symptoms, but further research must be conducted.
Researchers led a prospective study to examine this potential correlation. They obtained estimates of resilience and mood, as well as anxiety and post concussive symptoms from a control group as well as a group of TBI patients. They collected information on three occasions; at baseline, one week post-injury, and one month post-injury.
At baseline, each group exhibited similar characteristics. This was not the case at follow up. They differed in the areas of anxiety and post concussive symptom severity. Injury group and preinjury mood status were significant predictors of anxiety, mood and resilience.
