This drawing of the brain shows the lobes or major areas of the brain. How we act, feel, think, communicate, and move are controlled by different areas in the brain. When any of these areas or lobes is damaged by an injury, the functions that they control are affected. Although health care professionals talk about the lobes as if they were separate, there are a lot of connections between different areas of the brain. Any interruption of the connections can also result in changes in how the brain works.
Injury to the brain can cause several kinds of problems. The next section describes some of these problems and how they are treated.
