Doubt is Cast on the Contribution of Older Fathers’ Gene Mutations to Increased Mental Illness Risk in Their Children
Children born to older fathers have a higher risk of developing mental illnesses such as schizophrenia and autism spectrum disorders. Now, a new study suggests that age-related genetic mutations… Read More
Studies Find Many Genetic Links to Neuroticism
Researchers have long known that neuroticism—a personality trait characterized by a tendency toward negative emotions as well as anxiety, anger, envy, guilt and depression—is influenced by genetics.… Read More
Pathways That May be Disrupted in People with OCD
A genetic study of children with obsessive-compulsive disorder (OCD) and their parents, reported March 29, 2016 in Translational Psychiatry, has yielded important hints about genes and biological… Read More
By flipping a genetic switch, researchers were able to eliminate some autism-like behaviors in adult mice, suggesting that the adult brain might still have some degree of plasticity and that some… Read More
Researchers have developed a new model for studying schizophrenia by genetically engineering mice that produce high levels of a human protein, NRG1-IV, in the brain. NRG1-IV, a protein that helps… Read More
