The Link Between ADHD and the Ability to See Ghosts

I am reading an interesting book by Caren B. Goode right now called Kids Who See Ghosts.  I'm not very far into the book, but it is well written and well researched.  It brings up some interesting neurological research that I was unaware of in the first chapter.  According to Goode,
          "Brain mapping using EEG topography has found that creativity and intuition are associated with theta waves usually linked with daydreaming or fantasizing.  Theta waves are calm states in which intellectual activity at the conscious level isn't occurring. Children and adults with ADHD produce excessive theta waves.  Most people, children and adults alike, who see ghosts experience theta waves or brain-wave states of relaxation and meditation.  People who practice psychic skills have learned to concentrate in these states and master their psychic ability."

One of my constant concerns when I was working as a child therapist was the over medication of young children.  As a therapist,  I wasn't given an opportunity to question the psychiatrists who are given most of the control in the field, but the standard of care for children who have any problems was to diagnosis them almost exclusively with ADHD and medicate them.  Every child I saw in therapy was also being medicated for ADHD, despite the fact that research shows that this medication suppresses growth and causes other side effects.  In my opinion,  many of the children being medicated for ADHD didn't actually even have it.  They had PTSD or adjustment disorders etc., but of course that is another matter.  The ones who did have ADHD were often high functioning and performing well in school, but their behavior was a problem so they were medicated because it is a quick and easy fix to children who don't conform.

This research brings to light other questions.  In a world where ADHD is diagnosed in every other child,  could we be suppressing children's potential.   There have been links seen between ADHD and creativity and if is Good is right then perhaps there also might be links between ADHD and psychic abilities.  Are we suppressing our children's potential when we medicate them into silent, compliant behavior?   Are we shutting out the portion of their mind that might let them see beyond the concrete into a more abstract and deep world of ghosts and beauty?
