Traumatic brain injury (TBI) impacts approximately 1.7 million people in the U.S. each year, with causes ranging from falls and car accidents to sports injuries and blasts. The course Traumatic Brain Injury: An Overview of Etiology, Symptoms, and Treatment provides a concise yet comprehensive look at TBI, offering valuable insights for healthcare professionals, caregivers, and families aiming to support those affected.

TBI can present as mild concussions or severe injuries, with symptoms like headaches, confusion, or seizures that may not always appear on CT or MRI scans, complicating diagnosis. Secondary complications, such as brain swelling or increased intracranial pressure, can worsen outcomes if not addressed promptly. The course explores these challenges, detailing how to identify critical signs—like rapid neurological decline or pupillary changes—and understand injury mechanisms, from falls in older adults to blast injuries in veterans.

Through real-world examples, such as Marcus, a carpenter whose recovery relied on coordinated efforts from nurses, therapists, and social workers, the course illustrates the importance of interdisciplinary care. It covers essential tools like the Glasgow Coma Scale for assessing injury severity, the limitations of imaging, and evidence-based interventions for both acute and long-term care. Special emphasis is placed on unique populations: children at risk for shaken baby syndrome, seniors prone to fall-related injuries, and veterans dealing with blast injuries and PTSD.

With practical strategies and trusted resources, this course equips learners to enhance TBI care, from emergency response to chronic management, ultimately helping those affected regain independence and quality of life.
