Frontal Lobe Injury Symptoms

The frontal lobe section of your brain is known as your "emotional center." It not only controls emotion, it is also where your personality is formed. This area plays a role in memory, controlling movement and judgment, as well as social and sexual behavior. If this area becomes injured, it can affect many functions in the body. The type and severity of symptoms you develop depend on exactly which section of the frontal lobe is injured.
