Assessment and Management of Concussion at 1 Month Post-Injury

Systematic Assessment Approach

The American College of Emergency Physicians recommends using a standardized symptom checklist, such as the Rivermead Post-Concussion Symptoms Questionnaire, to systematically evaluate physical, cognitive, and emotional symptoms 1, 2
The most prevalent persistent symptoms at 1 month are fatigue (17.2%) and forgetfulness (14.6%), according to the Praxis Medical Insights guidelines 3
Documenting symptom severity on a 0-4 scale can help track recovery trajectory over time, as suggested by the Annals of Emergency Medicine 1, 2

Female gender is the strongest predictor of persistent symptoms beyond 3 months, according to the Praxis Medical Insights guidelines 4
Previous psychiatric history, such as depression, anxiety, or PTSD, is also a risk factor for prolonged recovery 4
High initial symptom burden at the time of injury is associated with a higher risk of persistent symptoms 4
A GCS score <15 at initial presentation is also a risk factor for prolonged recovery, as reported by the Annals of Emergency Medicine 2

The Praxis Medical Insights guidelines recommend immediately initiating graded aerobic exercise at 60-70% maximum heart rate for 15-20 minutes daily, gradually increasing duration and intensity as tolerated 4, 3, 5
Exercise should be performed below the threshold that exacerbates symptoms, and complete rest should not be prescribed at this stage 4, 3, 5
Vestibular rehabilitation, including habituation exercises, adaptation exercises, and balance training, can help improve physical functioning and readiness to return to activities 3, 5

For persistent headache, the Praxis Medical Insights guidelines recommend continuing acetaminophen 650-1000mg every 6 hours as needed, and adding NSAIDs if acetaminophen alone is insufficient 4
For neck pain with headache, spinal manual therapy, such as mobilization or manipulation of the cervical spine, can help reduce pain and improve return to activities 3, 5
For visual symptoms, oculomotor vision treatment, including vergence training, accommodative training, and eye movement exercises, can help improve visual function 3, 5
For cognitive symptoms, gradually increasing duration and intensity of cognitive activities as tolerated, with the goal of increasing participation without significantly exacerbating symptoms, is recommended 3

Providing systematic, individualized information about symptom management, expected recovery course, and self-care strategies can help reduce overall symptom burden and prevent memory problems, according to the Praxis Medical Insights guidelines 3

Referral to a concussion specialist or sports medicine physician is recommended if symptoms persist beyond 3 weeks from initial injury, significantly worsen despite conservative management, or if the patient plans to return to contact sports 4, 3

Most patients (80-85%) recover completely within 3 months of injury, while 15-20% experience persistent symptoms beyond 3 months, constituting post-concussion syndrome, according to the Praxis Medical Insights guidelines 4, 5
Problems may persist for at least 6 months and require continued medical care, social assistance, and financial support during recovery, as reported by the Annals of Emergency Medicine and Praxis Medical Insights guidelines 2, 3

In the first week after a mild concussion, memory deficits are most pronounced, with forgetfulness being one of the most common cognitive complaints together with attention and concentration problems【6】.

For individuals who develop persistent post‑concussion symptoms, memory problems can continue for at least six months and typically require ongoing medical care and social support【7】.

Female gender is the strongest predictor of persistent cognitive (including memory) symptoms after mild concussion【8】.
Pre‑existing psychiatric conditions such as depression, anxiety, or PTSD markedly increase the risk of prolonged memory problems following mild concussion【8】.
An initial Glasgow Coma Scale score below 15 is associated with a higher likelihood of prolonged memory symptoms【7】.
Loss of consciousness at the time of injury raises the risk of persistent cognitive (memory) complaints【7】.

Forgetfulness is the most frequently reported memory problem, affecting approximately 14.6 % of patients at follow‑up after mild concussion【7】.

Patients who present with the combination of headache, nausea, and dizziness have a 50 % probability of developing post‑concussion syndrome (including memory impairment) by six months post‑injury【6】.
