Assessment Procedures
- Medical history:
- Important to determine possible injury context (sports, fall, etc.).
- SCAT (Sport Concussion Assessment Tool):
- A standardized checklist used in athletics.
- Includes questions on symptoms such as:
- Headache, dizziness, nausea.
- Confusion, irritability, anxiety.
- Fatigue, amnesia.
- Helps evaluate the severity of symptoms.
Neurologic Exam
- Includes assessment of:
- Vision, hearing.
- Strength and sensation.
- Balance and coordination.
- Reflexes.
- Memory and concentration (cognitive testing).
When to Hospitalize
- Signs indicating serious injury:
- Severe headache, seizures, repeated vomiting.
- These require immediate imaging and hospitalization.
- Monitoring:
- Keep the patient overnight if symptoms are severe.
- Watch for increasing intracranial pressure.
- Treatment is directed at preventing secondary injury from swelling or pressure.
Mild Concussion
- No loss of consciousness or altered awareness.
- Symptoms last 2–3 days.
- Full recovery expected.
- Return-to-play protocol:
- Gradual return after symptoms resolve.
- Re-emergence of symptoms leads to sidelining and further rest.
- Baseline testing in athletes helps monitor injury severity.
Post-Concussion Protocol
- Rest initially.
- Gradual reintegration into activity.
- Continued symptom monitoring.
- If symptoms recur, pause activity again.
Severe or Prolonged Concussion
- Classic concussion often involves temporary loss of consciousness (minutes to hours).
- Longer symptoms:
- Weeks to months or longer.
- Called post-concussion syndrome.
- Symptoms include:
- Insomnia, depression, sensitivity to noise and light.
- Forgetfulness, concentration issues.
- Avoidance of screens and stress.
Management
- Full rest of the brain.
- Avoiding alcohol, screens, and stressful stimuli.
- Usually improves over time; some cases take months or over a year.
Summary
- Concussion diagnosis is supported by symptom assessment and baseline tests.
- Proper management involves initial rest and a gradual return to activity.
- Post-concussion syndrome can be long-lasting, requiring patience and supportive care.
