A new study found that teenagers with brothers and sisters who display no symptoms of antisocial behavior also struggle to recognize certain emotions. This impaired emotion recognition may be a factor contributing to the increased risk of developing conduct disorder in these individuals.
Researchers found that certain symptoms of conduct disorder, such as high-intensity defiant behavior, aggression, and destruction of property, indicate a higher likelihood of problems persisting into school age. Early diagnosis and treatment are crucial to help young children avoid recurring issues.
Researchers at UCLA have discovered a genetic link between PTSD and two gene variants, COMT and TPH-2. These variants may contribute to the onset and persistence of the disorder, suggesting that heredity influences a person's risk of developing PTSD. The findings could lead to faster diagnosis and better treatment for survivors.
