Question

Quizplus · Accepted Answer

Bipolar disorder has the strongest evidence for a genetic link, with a heritability estimate of up to 80%. Studies have shown that individuals with a first-degree relative with bipolar disorder have a much higher risk of developing the disorder themselves, compared to individuals in the general population. While there is also evidence for genetic influences in other disorders such as major depressive disorder and PTSD, the strength of the evidence is not as strong as that for bipolar disorder. Antisocial personality disorder is also thought to have a genetic component, but environmental factors, such as childhood experiences of abuse and neglect, also play a significant role in the development of the disorder.
