Depressive symptoms higher among children with ADHD

Friday, December 29th, 2006

Interesting study in children associating ADHD, social competence, and higher rates of depressive symptoms.

Prior research with both community and clinical samples has documented that rates of depression are significantly higher in children with ADHD than in other children. This is concerning because children with ADHD and depression, in addition to experiencing greater distress in the present are likely to have greater difficulty over the course of their development.

New Study on ADHD

Monday, December 4th, 2006

It is still not clear what causes ADHD. I’m asked this question so often and hope that someday we can answer it definitively. Meanwhile I would like to pass along what facts are available. We do know ADHD is a neurobiological condition and that genetics are are important factor. Researchers suspect that the brain neurotransmitter dopamine plays a role in the condition since many of the medications used to treat ADHD increase dopamine levels in certain areas of the brain. Prior studies have also shown higher than normal levels of dopamine transporter in a part of the brain called the striatum. However, newly released results from a brain-imaging study done in collaboration with Mt Sinai School of Medicine in New York, indicate that high levels of dopamine transporter did NOT correlate with ADD symptoms. In otherwords, the results are contradictory. That does not imply dopamine is not involved in symptoms of ADHD, but does suggest that dopamine transporter levels alone cannot account for symptoms of ADHD.

Subjects in this study had never received medication for their ADHD symptoms. Results will be published in an upcoming article in the journal called Neuroimage and a summary can be viewed at the address below. http://www.playfuls.com/news_003113_ADHD_Study_Results_Are_Released.html

New Research reports key to happiness: Think of three good things that happened today and analyze why they occurred.

Wednesday, November 29th, 2006

This research is really exciting and a great example of what we discuss with folks who have ADHD in cognitive behavioral therapy to help increase well being.

Associated Press: There’s no shortage of advice in how to become a happier person, as a visit to any bookstore will demonstrate. In fact, Martin Seligman of the University of Pennsylvania and colleagues have collected more than 100 specific recommendations, ranging from those of the Buddha through the self-improvement industry of the 1990s.

Video games and brain chemistry

Tuesday, November 28th, 2006
A recent  study of adolescents finds that violent video games stir up the brain’s motional-response center while reducing activity in regions linked to self-control. “After playing a violent video game, these adolescents had an increased activity in the amygdala, which is involved in emotional arousal,” Mathews said. “At the same time, they had decreases in activity in parts of the brain which are involved in self-control,” he added. The findings were to be presented Tuesday in Chicago at the annual meeting of the Radiological Society of North America. (more…)

Sorry kids…..new research shows school tests do enhance learning!

Wednesday, November 22nd, 2006

Taking tests tends to not be an area of strength for students with ADHD, particularly if they are not recieving accommodations. A study in the November issue of the Journal of Experimental Psychology reported that school tests do help kids remember what they’ve learned — even information that’s not on the tests. In three experiments with 54 to 84 undergraduates, researchers at Washington University, St. Louis, concluded that students who wrote tests had better enhanced long-term recall of all material they studied, while students who weren’t tested recalled much less of what they’d studied, even after they were given extra time to review the material. They said that exams are more than just a way of scoring students — they’re a “powerful memory enhancer,” too. While it was known that testing strengthened students’ subsequent recall of the tested material, this study also found that typical classroom tests — as opposed to high-stakes standardized tests — also boost recall of material that’s not included in a test.

The researchers also found that the use of memory strategies during learning may be especially helpful when students are writing short-answer and essay exams, which tend to rely on the recall of a range of information.

Happiness improves our health!

Monday, November 13th, 2006

Recent research from Carnegie Mellon this week strengthens the importance of addressing well-being in our patients with ADHD. We have known for a long time that people’s lives and level of happiness are often negatively impacted by symtoms of ADHD. By managing symptoms and improving well-being, people may also be improving their general health.

Depression Study

Thursday, November 2nd, 2006

Landmark govt. study examines depression

Depression and ADD commonly occur together in both children and adults. The above link provides newly released information regarding the use of medications to treat depression. Published in the American Journal of Psychiatry Nov issue, this large government funded study on depression reminds us that anti-depressant medications may take time to be effective. It is helpful to note this was not a pharmaceutical company funded study. There were over 3,500 adult patients enrolled in the trial which makes this a more representative sample of what we see in everyday practice. The study concludes that 2/3rds of patients suffering from depression can be helped by medication if they are willing to go through several anti-depressant medication trials and willing to wait long enough for the medication to be effective. The message for all of us is one of patience.
