Heres some of the info from the Brain Institute.org I was talking about:
Frontal Lobe Damage
Have you ever been told your personality is "left brain dominant" or maybe "right brain dominant"? Do consider your actions to be driven by your emotions or logic? If you identify yourself as left brain or right brain dominant chances are you are aligning yourself with the areas of the brain that control the functions that best describe you. Well what if you suffer a traumatic brain injury (TBI) to the area of your brain that you feel is more dominant? Will your personality change? Will your mood be effected? Will you have to learn to write with your other hand? To answer these questions you must understand the different hemispheres of the brain and determine how the severity of the TBI will affect them.
A frontal lobe brain injury refers to a traumatic brain injury that affects the front area of your brain. This is your brain’s largest lobe.
