Most researchers agree that brain and environmental factors probably contribute as well.

Genetic Factors

Considerable research in multiple families, adoption, and twin studies has focused on the question of bipolar disorder's heritability—whether bipolar disorder can be inherited.

This is important for genetic theories because identical twins occur when one fertilized egg splits in two, meaning that they share the same genetic material. Fraternal twins, on the other hand, come from separate fertilized eggs, so their inherited genes can be different.

There is overwhelming evidence that bipolar disorder can be inherited and that there is a genetic vulnerability to developing the illness.
