How about a quick tour through the brain...

Here is a quick run through the brain and the relationship to behavior.  Please never try to diagnose anyone.
If there is damage to the brain stem (the area in the back of the head near the bony areas) there can be disorientation, frustration and anger.  With damage to the limbic system, which is a little higher up, there can be explosive rage (PTSD) and problems with the other emotions and affect.  When the temporal lobes, which are over the ears, is damaged then seizures can appear and a number of behavioral disorders.  The frontal lobes, which is in the front part of the brain, can be easier to damage.  This can result in a lack of emotional control decreased judgement, increased impulsiveness, irritability and aggression.

LENS neurofeedback can help with these problems,  It is gentle and effective.  Come to my open house on June 22 between 4 and 7 at 224 E. Willamette.  I will teach you about this system.
