Question

Quizplus · Accepted Answer

Both mood disorders (such as bipolar disorder and major depressive disorder) and schizophrenic disorders (such as schizophrenia and schizoaffective disorder) have been found to have a strong genetic component in their development. This has been supported by studies of families and twin studies. Eating disorders such as anorexia nervosa and bulimia nervosa do have some genetic components, but they also have significant cultural and environmental factors. Dissociative disorders, such as dissociative identity disorder, have not been found to have a strong genetic component.
