Are you suffering from depression? If yes, then your teenage kid may be prone to higher risk-taking and rule-breaking behaviour that can make them rebellious and disobedient, says a study.According to researchers, parental depression contributes to greater brain activity in areas linked to risk taking in adolescent children, leading to more rule-breaking behaviours."This is the first evidence to show that parental depression influences children's behaviour through the change in the adolescent's brain," said lead study author Yang Qu from University Of Illinois at Urbana-Champaign.
