Individuals with a history of traumatic brain injury report increased risk of chronic pain. Following TBI, photosensitivity is also a common symptom of chronic pain and is prevalent in other forms of chronic pain. Based on their Neurobehavioral Symptom Inventory results, the TBI group was divided into 120 symptomatic TBI participants and 113 asymptomatic TBI participants. The Symptom Impact Questionnaire Revised and the Michigan Body Map surveyed showed a significant increase on self-reported chronic pain measures in comparison to a-TBI and no-TBI participants, including the Symptom Impact Questionnaire Revised and the Michigan Body Map. Despite differences in chronic pain reports, pain sufferers' stories remained, groups maintained similar pressure-pain thresholds. Moreover, s-TBI participants were more sensitive to light, and VPT was correlated with SIQR rankings among all participants. These results show that photosensitivity is linked to self-reported chronic pain and disability in people with chronic TBI symptomatology.

A variety of psychopathological and neurobehavioral disorders have been attributed to traumatic brain injury. Moderate and severe TBI can cause personality changes such as impulsivity, acute irritability, affective instability, and apathy. Mild TBI, once thought of as a benign condition, is now known to be linked with a variety of affective signs, suicidality, and the onset or new onset of several psychiatric disorders, including posttraumatic stress disorder and major depressive disorder. TBI-related mental health disorders have a multitude of physical and etiological aspects, and recent epidemiological and mechanistic research has emphasized this.
