Philip Shaw, M.D., Ph.D., of the National Institute of Mental Health, Bethesda, Md., and team compared 105 children who suffered from ADHD, average age 10.1, to 103 children who did not have ADHD.  They used MRI (magnetic resonance imaging) and DNA tests.  64% of the ADHD children were followed up six years later. </DIV><BR /><DIV>
The scientists found that those with the 7-repeat form of DRD4 tended to have thinner tissue in the right orbitofrontal/inferior prefrontal and posterior parietal cortex - parts of the brain that deal with attention.  This was the case for both the children with ADHD and the controls.</DIV></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.medicalnewstoday.com/articles/79300.php">
They also found that similar areas were also generally thinner among the children with ADHD, compared to the controls.</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/B9F764C0-1C40-4707-BBDB-EC459BB7C7F7/blog/" title="blog or email this clip"><img src="http://content9.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
