The study, titled "Meta-Cognitive Therapy," is now published in the American Journal of Psychiatry. http://phys.org/news189179627.html Medicine & Health Tue, 30 Mar 2010 15:10:01 EST news189179627 (PhysOrg.com) -- Many elementary-aged children with clinically elevated attention problems in one grade no longer demonstrate these problems the following year in their new classroom, according to a study led by researchers at Duke University. http://phys.org/news188504431.html Medicine & Health Mon, 22 Mar 2010 19:40:01 EST news188504431 A new study suggests a trend toward developing hyperactivity among typically developing elementary-school-aged siblings of autistic preschoolers and supports the notion that mothers of young, autistic children experience more depression and stress than mothers with typically developing children. http://phys.org/news187276918.html Medicine & Health Mon, 08 Mar 2010 13:22:26 EST news187276918 A genetic link between schizophrenia and autism is enabling researchers to study the effectiveness of drugs used to treat both illnesses. http://phys.org/news186214402.html Medicine & Health Wed, 24 Feb 2010 06:13:45 EST news186214402 Scientists know little about how the brain creates and controls emotions - an uncertainty that presents a major obstacle in the effort to develop treatments for emotional disorders. "The study of the brain science of emotion is in its infancy," says Howard Hughes Medical Institute (HHMI) investigator David Anderson, "yet emotional and psychiatric disorders continue to take an enormous toll on human society." http://phys.org/news185943692.html Medicine & Health Sun, 21 Feb 2010 07:40:01 EST news185943692 Until now, attention-deficit/hyperactivity disorder (ADHD) was related to alterations in the brain affecting attention and cognitive processes. Spanish researchers at Universitat Autňnoma de Barcelona and the Vall d'Hebron University Hospital for the first time have discovered anomalies in the brain's reward system related to the neural circuits of motivation and gratification. In children with ADHD, the degree of motivation when carrying out an activity is related to the immediacy with which the objectives of the activity are met. This would explain why their attention and hyperactivity levels differ depending on the tasks being carried out. http://phys.org/news184414655.html Medicine & Health Wed, 03 Feb 2010 10:30:01 EST news184414655 ADHD, or attention-deficit/hyperactivity disorder, is among the costliest of behavioral disorders. Its combination of inattention, impulsivity and hyperactivity leads to accidental injuries, school failure, substance abuse, antisocial behavior and more. Yet despite nearly a century of study, the disorder's roots remain mysterious. http://phys.org/news183906394.html Medicine & Health Thu, 28 Jan 2010 13:20:06 EST news183906394 The adverse effects of prenatal alcohol exposure on behavioral, cognitive, and social development can lead to a range of symptoms referred to as fetal alcohol spectrum disorder (FASD). Attention and cognition problems seen in individuals with a history of prenatal alcohol exposure often resemble those linked to attention deficit hyperactivity disorder (ADHD). An assessment of these disorders has found that while children with FASD may meet the behavioral criteria for ADHD, their attention difficulties differ in subtle but important respects. http://phys.org/news183834884.html Medicine & Health Wed, 27 Jan 2010 17:40:15 EST news183834884 Children who are mixed-handed, or ambidextrous, are more likely to have mental health, language and scholastic problems in childhood than right- or left-handed children, according to a new study published today in the journal Pediatrics. http://phys.org/news183546926.html Medicine & Health Mon, 25 Jan 2010 00:00:01 EST news183546926 (PhysOrg.com) -- Scientists at the Queensland Brain Institute have found a way to measure the attention span of a fly, which could lead to further advances in the understanding of attention-deficit hyperactivity disorder (ADHD) and autism in humans. http://phys.org/news183227083.html Medicine & Health Wed, 20 Jan 2010 17:00:01 EST news183227083 (PhysOrg.com) -- Two brain areas fail to connect when children with attention deficit hyperactivity disorder attempt a task that measures attention, according to researchers at the UC Davis Center for Mind and Brain and M.I.N.D.
