Overview
Concussion with loss of consciousness (LOC) involves a transient alteration of mental status following a traumatic brain injury, often characterized by impaired consciousness lasting seconds to minutes 1.Diagnosis
Clinical assessment focusing on history of head trauma and observed changes in mental status.
Neurological examination to identify signs of altered consciousness, focal deficits, or worsening symptoms.
Imaging (CT/MRI) typically reserved for cases with persistent symptoms, worsening condition, or suspicion of intracranial pathology 1.Management
Initial Management: Immediate removal from play/activity, rest, and monitoring in a quiet environment.
Symptom-Limited Activity: Gradual return to normal activities based on symptom resolution, avoiding cognitive and physical overexertion 1.
Medication: No specific pharmacological treatment recommended for acute management; symptomatic relief with analgesics if needed (e.g., acetaminophen) 1.Special Populations
Pediatrics: Similar management principles apply, with emphasis on gradual return to play protocols tailored to age and symptom recovery 1.
Elderly: Increased vigilance for delayed onset of symptoms and comorbid conditions affecting recovery and management 1.Key Recommendations
Immediate Removal from Activity: Remove individuals from physical activities post-concussion with LOC until fully asymptomatic 1 (Evidence: Strong).
Gradual Return to Play: Implement a stepwise return-to-play protocol based on symptom-free intervals 1 (Evidence: Strong).
Avoid Cognitive Overload: Limit cognitive and physical demands until symptoms resolve to prevent exacerbation 1 (Evidence: Moderate).References
