Concussion – Management
- The majority (80–90%) of concussions resolve in 7–10 days. However, recovery time may be longer in adolescents and children.
- Historically, patients were advised to rest (cognitively and physically) until symptoms resolved.
- Current guidelines indicate after 24–48 hours of physical and cognitive rest, patients should attempt light physical and cognitive activity as long as symptoms are stable or improving.
Return to activity
- Stage 1: Initial Rest
- Physical and cognitive rest for 24–48 hours in a quiet environment with limited distractions (pending acute symptom resolution).
- Complete physical and cognitive rest for over 48 hours is generally not recommended, as there is no evidence that this is beneficial.
- Stage 2: Gradual Increase in Activity Level as Tolerated
- Perform simple tasks around the home, read, or do light physical activity (ie. walking or riding a stationary bike).
- Symptoms usually get slightly worse with increased activity level, but these symptom changes tend to go away within a day. If symptoms are persistently worse with increased activity, return to the previous level of activity.
- Stage 3: Full Return to Activity
- Gradually taper off extra rest breaks.
- Do not return to risky activities where another concussion could occur, such as contact sports or dangerous job tasks, until symptoms have fully resolved.
- 30–80% of patients with mild to moderate TBI will experience at least one symptom of postconcussion syndrome (See Concussion Diagnosis).
- Treatment includes management of headache, sleep disturbances, and psychologic and cognitive complaints that can occur after concussion.
- Headache is the most common symptom following a concussion.
- Acetaminophen and NSAIDs are reasonable adjuncts to cognitive and physical rest during the first few days after injury, but can be ineffective or cause medication-overuse headaches if used regularly after the initial stages of injury.
- Amitriptyline has been widely used for post-traumatic tension-type headaches, and for symptoms such as irritability, dizziness, depression, fatigue, and insomnia.
- An inpatient program of repetitive IV dihydroergotamine and metoclopramide may provide relief of refractory chronic post-traumatic headaches.
Criteria For Hospital Admission
- Patients at risk for immediate complications from head injury, including patients with:
- GCS <15
- Abnormalities on head CT (eg, intracranial hemorrhage, ischemia, mass effect, midline shift)
- Bleeding diathesis or oral anticoagulation
- Neurologic deficit
- Recurrent vomiting.
Criteria For Safe Discharge Home
- Outpatient observation may be permitted for the patient whose neurologic condition is unlikely to deteriorate.
- There is substantial evidence that patients with a GCS = 15, normal examination and head CT, and no predisposition to bleeding are unlikely to suffer subsequent neurologic deterioration.
