Attention-deficit diagnosis depends on kids’ birthdays, study shows

Kids who are young for their grade level are unusually likely to be diagnosed with attention-deficit hyperactivity disorder (ADHD) — a worrying sign that, for many kids, plain old immaturity has been misdiagnosed as a clinical disorder.

In two separate studies — both appearing in a forthcoming issue of the Journal of Health Economics — researchers at Michigan State University and at North Carolina State University analyzed the relationship between date of birth and ADHD diagnosis. Both studies found that, for kids with birthdays just before the kindergarten-eligibility cut-off date in their state, the odds of an ADHD diagnosis were much higher than for kids who start school almost a full year older, born just after the eligibility cut-off.

In the Michigan State study, for example, the youngest kids were found to have 60% greater risk of ADHD diagnosis, according to USA Today, which first reported the study results this morning. That newspaper reports that — based on these findings — nearly 1 million children may be misdiagnosed, simply because they are less mature than their classmates.

    Much better than the article on acupuncture. I suggest you learn more about your subject; perhaps a visit to an acupuncturist before you write.

    I strongly disagree. This article lacks through evidence, it main introduces a claim with weak premises. I wish more were written.

    Some children have behavioral issues due to maturity, age, lack of discipline, or problems at home but there are SOME children with real neurological disorders. It may manifest itself in withdrawn behavior or hyper behavior – it depends on the child. I like what Brain Balance has to say about the issue – http://www.brainbalancecenters.com . Strengthening brain communication through education, exercises, occupational therapy, etc. can make a big difference without drugs. I understand the difficult job that teachers have with 20 or more students who learn differently and at different levels. Never-the-less, it’s not as “easy” as every child with behavior or attention problems having ADHD. Some have sensory issues, etc.

    ADHD is NOT the whole story. ADHD has risen at the same level as diabetes and there is a llink! Blood sugar is the root cause link for ADHD and Alzhemiers. The drug makers control the health care and much of Washington

    A filmmaker has been reversing diabetes WITHOUT medication in much of the world and the USA drug makers are still silent on the story to the people http://spirithappy.wordpress.com/2010/04/28/type-2-diabetes-cure-2010-spirit-happy-diet-works-well/

    Prescribing mind altering drugs to children should be considered one of the most serious of crimes. A cursory study of children shows that a vast majority have a short attention span at a young age. How did this get classified as a “mental illness?” When drug companies and psychiatrists (charlatans that they are) got the idea there was money to be made. Turns out there are other things inserted into the lives of our children that can contribute to the “symptoms” of ADHD, such as pesticides, food additives and the like (http://organicconnectmag.com/wp/2010/08/risk-to-kids-from-toxic-pesticides-may-be-underestimated-study-finds/). For a rather sad if not a little bit scary exercise, ask a psychiatrist to list the documented symptoms of ADHD. They won’t be able to do it.
