Brain difference in psychopaths identified
Professor Declan Murphy and colleagues Dr Michael Craig and Dr Marco Catani from the Institute of Psychiatry at King's College London have found differences in the brain which may provide a biological...
View ArticleAntibodies to strep throat bacteria linked to obsessive compulsive disorder...
A new study by researchers at Columbia University Mailman School of Public Health's Center for Infection and Immunity indicates that pediatric obsessive-compulsive disorder (OCD), Tourette syndrome...
View ArticleSex-based prenatal brain differences found
Prenatal sex-based biological differences extend to genetic expression in cerebral cortices. The differences in question are probably associated with later divergences in how our brains develop. This...
View ArticleBefore or after birth, gene linked to mental health has different effects
Scientists have long eyed mutations in a gene known as DISC1 as a possible contributor to schizophrenia and mood disorders, including depression and bipolar disorder. Now, new research led by Johns...
View ArticleCanine compulsive disorder gene identified in dogs
A canine chromosome 7 locus that confers a high risk of compulsive disorder susceptibility has been identified through a collaboration between the Behavior Service at the Cummings School of Veterinary...
View ArticleReceptor variant influences dopamine response to alcohol
A genetic variant of a receptor in the brain's reward circuitry plays an important role in determining whether the neurotransmitter dopamine is released in the brain following alcohol intake, according...
View ArticleHigher anxiety, depression among women may have basis in cell signals
There may be a biological reason why depression and other stress-related psychiatric disorders are more common among women compared to men. Studying stress signaling systems in animal brains,...
View ArticleGene links to anorexia found
Scientists at The Children's Hospital of Philadelphia have identified both common and rare gene variants associated with the eating disorder anorexia nervosa. In the largest genetic study of this...
View ArticleRestoring emotional memory in a rat model of major depressive disorder
Deficits in emotional memory processing associated with major depressive disorder (MDD) are shown to be reversible by distinct antidepressants, shows researchers at Karolinska Institutet in an animal...
View ArticleGene variants in autism linked to brain development
New research on the genomics of autism confirms that the genetic roots of the disorder are highly complicated, but that common biological themes underlie this complexity. In the current study,...
View ArticleResearchers create stem cells from schizophrenia patients
Using skin cells from adult siblings with schizophrenia and a genetic mutation linked to major mental illnesses, Johns Hopkins researchers have created induced pluripotent stem cells (iPS cells) using...
View ArticleAre teenagers wired differently than adults?
Parents have long suspected that the brains of their teenagers function differently than those of adults. With the advent of magnetic resonance imaging, or MRI, we have begun to appreciate how the...
View ArticleRwandan genocide survivors provide new insights into resilience and PTSD
