There are indeed 'standardized (psychological) tests' for ADHD. Such testing is conducted by licensed psychologists and medication interventions are monitored by PHYSICIANS, board certified pediatricians and child psychiatrists - not chiropractors. In addition, the standards for suspecting the disorder are well documented. There is a genetic marker for ADHD. That the ADHD brain functions differently is evident on a PET scan. For ACCURATE information on ADHD, go to the National Institute of Mental Health Web site and request the free copy of the current ADHD research, in booklet form. (Look under "publications.")
ADHD is FEDERALLY RECOGNIZED disability.
Be wary of 'opinions' expressed by those who do not have ADHD-specific education and training and are clearly
not qualified if they say such things as "there is no standardized test for ADHD."
