In plain language
Traumatic brain dysfunction after force to the head or body transmits to the brain during sport.
Clinical Significance & Management
Prolonged strict rest is generally discouraged. After 24–48 hours of relative rest, gradually resume daily activity and light aerobic exercise as tolerated. Avoid collision and fall risks; contact sport requires staged assessment and clearance.
Symptoms & Clinical Presentation
Headache, dizziness, attention or balance disturbance
Etiology & Injury Mechanisms
- Acceleration-deceleration forces from head, neck or body impact
Diagnostics & Imaging Guide
Multidomain clinical assessment; imaging to exclude more serious injury
Treatment Options
Immediate removal and assessment, then relative rest and progressive activity
Rehabilitation Milestones & Timeline
Rehabilitation depends on the diagnosis, procedure and associated injuries. Progression requires assessment of healing, symptoms and function; elapsed time or a single test cannot determine readiness for sport.
Progressive rehabilitation
Gradual learning and exercise; medical clearance for contact risk
Evidence-Based Clarifications
Loss of consciousness and abnormal routine imaging are not required.
