Worldwide, 3󈝸% of children are affected with the disorder. Key symptoms of ADHD include age-inappropriate hyperactive and impulsive behaviour and/or a reduced ability to focus attention. Clinically, three different ADHD subtypes are classified, a primarily inattentive subtype, a primarily hyperactive/impulsive subtype, and a combined subtype in which patients show deficits in both domains. At the level of the brain, small aberrations in both structure and activity of specific brain regions, as well as the connectivity between brain regions have been observed in children and adults with ADHD (Valera et al., 2007; Schneider et al., 2006; Makris et al., 2008; Pavuluri et al., 2009; Broyd et al., 2009). http://www.physorg.com/news172215581.html Medicine & Health Tue, 15 Sep 2009 06:41:20 EST news172215581 A brain-imaging study conducted at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory provides the first definitive evidence that patients suffering from attention deficit hyperactivity disorder (ADHD) have lower-than-normal levels of certain proteins essential for experiencing reward and motivation. http://www.physorg.com/news171652613.html Medicine & Health Tue, 08 Sep 2009 18:17:27 EST news171652613 (AP) -- Calls to poison control centers about teens abusing attention-deficit drugs soared 76 percent over eight years, sobering evidence about the dangerous consequences of prescription misuse, a study shows. http://www.physorg.com/news170307731.html Medicine & Health Mon, 24 Aug 2009 05:00:01 EST news170307731 (AP) -- China is investigating the death of a teenager who was allegedly beaten to death in a camp designed to treat Internet addiction, state media said. http://www.physorg.com/news168777628.html Technology Thu, 06 Aug 2009 12:10:04 EST news168777628 A study in the Aug.1 issue of the journal Sleep found that alcohol consumption during pregnancy and small body size at birth predict poorer sleep and higher risk of sleep disturbances in 8-year-old children born at term.
