Rate of ADHD Diagnosis has Increased 66% in 10 Years.

Tuesday, March 20th, 2012

This new study shows a 66% increase in the diagnosis of ADHD over the last 10 years, an even bigger increase in the rise of ADHD than was previously thought. I am appalled that the author’s oversimplified explanation is that this is simply due to an increased awareness of ADHD. This implies, of course, that over-diagnosis is no part of this at all. Clearly he has not read the study posted march 7 showing that simply being born in December rather than January increases the chance of being diagnosed with ADHD by 31% in boys and 70% in girls.

Rate of ADHD Diagnosis up 66%.

Cell phones exposure during pregnancy linked to hyperactivity in mice.

Monday, March 19th, 2012

The study below showed that the pregnant mice exposed to radiation from a cell phone near the cage had offspring that were more likely to have behavioral problems similar to ADHD. Given the level of cell phone use this is a little concerning. Of course it is a long way from one mouse study to proving this will be a problem in humans, but to be safe I would suggest pregnant women not carry their cell phones next to their body on a regular basis.

Youngest Children in Class Misdiagnosed with ADHD

Wednesday, March 7th, 2012

A new research study, from Canda, showing that the youngest children in a class are much more likely to be diagnosed with ADHD and treated with medication. In Canada, where Jan 1 is the cutoff, boys born in December were 30% more likely to receive an ADHD diagnosis and 41% more likely to receive a medication than boys born in January!!! For girls it was WORSE, they were 70% more likely to receive a diagnosis and 77% more likely to receive medication. What does this show? To a large extent, WE ARE UNABLE TO DISTINGUISH ADHD FROM SIMPLY BEING YOUNGER AND A LITTLE LESS MATURE. It is frightening to contemplate how many families are told they have impaired children and need a lifetime of medication simply based on what time of year they were born!

this is the second study confirming the same point. In a U.S. study in 2011, the youngest kindergartners were 60 percent more likely to be diagnosed with ADHD than the oldest children in the same grade. Overall, that study found that about 20 percent — or 900,000 — of the 4.5 million children currently identified as having ADHD likely have been misdiagnosed. Both of these articles should be shared with anyone working with ADHD children.

New Research Confirms Video Games Increase ADHD Symptoms

Tuesday, March 6th, 2012

Video and ADHD 2012 -Another research study demonstrates that video games contribute to worsening symptoms of ADHD. In this study over 3000 children and teenagers in Singapore were followed for over 3 years. the results clearly show that increased video game time led to worsening ADHD symptoms. It also showed that children with ADHD were more likely to spend more time playing video games, so it is a negative 2-way cycle. Violent video games were worse, but the impact on ADHD was negative whether the games were violent or not.
This is not the first study showing the negative effect of video games on ADHD, but the large numbers of children studied make it a strong one. The size of the effect was not large, but was larger, for example, than that of any gene associated with ADHD.
the authors offer several hypothesis for why video games should worsen ADHD symptoms, the most likely, it seems to me, is the “excitement” hypothesis. This is the idea that video games are so exciting, and have so much dramatic feedback, that school instruction and usual learning tasks (like doing homework) pale by comparison. However the research itself could not determine if this was the actual cause.
BOTTOM LINE: Video game time in children with ADHD should be carefully controlled and violent videos discouraged.
