One Twin Was Hurt, the Other Was Not. Their Adult Mental Health Diverged.

Twins provide valuable insights to research psychologists studying the effects of genetics, environment, and life experiences. In a recent study, researchers found that childhood trauma plays a significant role in the divergence of mental illness experiences in twins. The study, conducted on adult twins in Sweden, revealed that those who reported childhood trauma were more than twice as likely to be diagnosed with a psychiatric illness. Each additional adverse experience further increased the odds of a mental illness diagnosis. These findings highlight the impact of early trauma on mental health outcomes.
