- Gene Triggers Obsessive Compulsive Disorder-Like Syndrome in Mice
-
August 22, 2007
•
Press Release
Using genetic engineering, researchers have created an obsessive-compulsive disorder (OCD) - like set of behaviors in mice and reversed them with antidepressants and genetic targeting of a key brain circuit. The study, by NIH-funded researchers, suggests new strategies for treating the disorder. - Behavioral Interventions Effective for Preschoolers with ADHD

Science Update
Two types of early interventions designed to reduce symptoms of attention deficit-hyperactivity disorder (ADHD) in preschoolers may be effective alternatives or additions to medication treatment, according to a recent NIMH-funded study. - New Studies Search for Clues to Mental Illness in Gatekeepers of Gene Expression
-

•
Science Update
What goes awry in the brain to cause mental illness may ultimately be traced to glitches in genes - but not necessarily the parts of genes commonly suspected. Rather than the areas of genes that code for proteins, the secrets may be hidden in mysterious short sequences of genetic material called microRNAs. - Half of Children With Autism May be Diagnosable Soon After Their First Birthday

•
Science Update
About half of children with autism spectrum disorders (ASD) can be diagnosed soon after their first birthday; others with the disorder may appear to develop normally until that age and then falter or regress during their second year, NIMH-funded researchers have discovered. - Parents' Diagnoses Help to Distinguish Childhood Bipolar Disorder from Severe Mood Dysregulation
-

•
Science Update
The parents of children who have bipolar disorder are more likely to have bipolar disorder themselves than the parents of children who have severe mood dysregulation (SMD). This finding challenges the notion of some research that suggests SMD is a type of more broadly defined childhood bipolar disorder. - Gene Predicts Better Outcome as Cortex Normalizes in Teens with ADHD

Science Update
Brain areas that control attention were thinnest in children with attention deficit hyperactivity disorder (ADHD) who carried a particular version of a gene in a study by NIMH. - New Technique Pinpoints Crossroads of Depression in Rat Brain
-

•
Science Update
NIMH-funded scientists have developed a new high-speed technique for imaging brain activity and used it to pinpoint a circuit signal in rats that may be at the crossroads of depression. - Success or Failure of Antidepressant Citalopram Predicted by Gene Variation
-
August 1, 2007
•
Press Release
A variation in a gene called GRIK4 appears to make people with depression more likely to respond to the medication citalopram (Celexa) than are people without the variation, a study by NIMH has found. - Faster-Acting Antidepressants Closer to Becoming a Reality
-
July 24, 2007
•
Press Release
A new study has revealed more about how the medication ketamine, when used experimentally for depression, relieves symptoms of the disorder in hours instead of the weeks or months it takes for current antidepressants to work. - Improvement Following ADHD Treatment Sustained in Most Children
-

Press Release
Most children treated in a variety of ways for attention deficit hyperactivity disorder (ADHD) showed sustained improvement after three years in a major follow-up study funded by NIMH.
