The frontal lobe occupies the front third of the brain and serves as the executive control center for human behavior and cognition. This region is responsible for complex functions including planning, decision-making, problem-solving, impulse control, emotional regulation, and social behavior. When trauma damages the frontal lobe—whether through direct impact, acceleration-deceleration forces, or secondary injury from swelling and bleeding—these critical functions become impaired.
Frontal lobe injuries commonly occur in motor vehicle accidents, particularly in head-on collisions and T-bone accidents where the front or side of the head strikes the steering wheel, dashboard, or window. The injury can range from mild contusions to severe traumatic brain injury with permanent deficits. What makes frontal lobe injuries particularly insidious is that victims may appear physically fine while experiencing profound cognitive and behavioral changes that devastate their personal and professional lives.
Medical professionals classify frontal lobe injuries based on location and severity. Damage to the dorsolateral prefrontal cortex affects executive functions like planning and working memory. Injury to the orbitofrontal cortex impairs impulse control and social judgment. Damage to the medial frontal regions affects motivation and emotional regulation. Understanding the specific location and extent of injury is crucial for both treatment planning and legal claims.
