= The frontal lobe (Shown left in purple) controls emotions, = = judgments, sequencing events (multi-step tasks), interacting = = with others, facial expressions, the thinking process = = (ie. being able to conceive of and choose between complex = = alternatives in a social environment) and mood change (2). =


 * Children that experience head injury/trauma in the frontal lobe **
 *  area are also more susceptible. Toxins can also be a source to **
 *  the disorder. PCB's and lead are the most commonly found to **
 *  have a correlation to ADHD. **


 *  A child with ADHD may have a different brain structure than other **
 *  children.There can also be differences in areas of the brain that affect **
 *  attention and impulse control. The function of the chemicals dopamine **
 *  and norepinephrine may also be affected in these children. **


 *  These chemicals are the chemicals that help and deal with attention and **
 *  activity. These children's brains also develop about three years behind **
 *  other children. Their brains can change and therefore many children can **
 *  grow out of the disorder. Although adults can have the disorder it always **
 *  begins in childhood (4). **
