Traumatic Brain Injuries and Concussions

These flashcards cover key concepts from the lecture on traumatic brain injuries and concussions, including definitions, symptoms, protocols, and preventive measures.

Traumatic Brain Injury (TBI)

Damage to the brain from an external physical force that can result from a violent blow, jolt, strike, or penetrating injury to the head.

Concussion

A type of mild TBI that can range in severity and can have long-term serious impacts.

Metabolic Cascade

A series of physiological changes that occur in the brain after a concussion, affecting balance and delivery of energy.

Second-Impact Syndrome (SIS)

A condition where an individual sustains a second head injury before recovering from the initial trauma, which can be extremely dangerous.

Signs of a Concussion

Symptoms such as confusion, poor balance, slurred speech, and loss of consciousness indicating a possible concussion.

Long-term Symptoms of Concussion

Symptoms that persist beyond 3 months after a concussion, requiring Cognitive Rehabilitation Therapy (CRT) for management.

Return to Play Protocol

A six-step process for safely reintegrating athletes into physical activity after a concussion.

Baseline Concussion Testing

Pre-injury assessment used to evaluate an athlete's cognitive function, allowing comparison with post-injury performance.

Cognitive Rehabilitation Therapy (CRT)

A therapeutic approach tailored to help individuals recover cognitive functions affected by concussions.

Risk Factors for Concussions

Groups at higher risk for concussions include children under 4, teenagers in recreational activities, older adults, and athletes in collision sports.

Signs and Symptoms of Concussion

Headache, dizziness, nausea, confusion, mood changes, and difficulty concentrating are common indicators of a concussion.

Prevention of Concussions

Strategies include wearing protective gear during sports, practicing safety precautions, and educating individuals about the signs and symptoms.
