Concussive Symptoms in Emergency Department Patients Diagnosed with Minor Head Injury

Blast-related mild traumatic brain injury in the acute phase: Acute stress reactions partially mediate the relationship between loss of consciousness and symptoms

“…This change corresponded with increased somatic symptom severity and endorsement of more depressive symptoms than those without LOC [13]. This was consistent with evidence and clinical experience from sports medicine, rehabilitative and emergency department settings that has indicated that LOC predicted longer recovery time and increased symptoms [15][16][17][18][19][20][21][22][23][24].…”

Persistent problems 1 year after mild traumatic brain injury: a longitudinal population study in New Zealand

“…[4][5][6][7] A study of patients attending an emergency department after minor head injury revealed that 63% of participants reported experiencing post-concussion symptoms 1 month post-injury. 8 Longer-term studies suggest that symptoms may persist for up to 3 years after injury. 2,9,10 Further longitudinal studies are required, however, to improve understanding of the extent of difficulties experienced after mTBI and the recovery trajectory.…”

Risk of suicide after a concussion

“…50 Differentiating a weekend from a weekday concussion was based on the date of medical care, which closely corresponds to the date of injury. 51,52 For patients with multiple concussions, we used the date of the first concussion, such that each person was counted once in the analyses; repeat concussions were tracked for separate secondary analyses. Further data on duration of amnesia, loss of consciousness, mechanism of injury, severity of symptoms, delays in seeking care and standardized concussion assessment scores were not available.…”
