On the other hand, the mood disorder is even more retrievable if they fall under the category of identical twins. Other biological theories revolve around the brain and its neurotransmitters, for example, within the ventral striatum people with bipolar disorder tend to have a sensitivity to reward cues (Lin, 2016). This allows them to be much more reactive or sensitive to things as well as seek out immediate gratification rather than pay attention to long-term consequences. Such behavior may be due to the dysregulated dopamine system found within their neurotransmitters. In relation, the psychological theories focus on the idea of rewarding as well but also punishment and stress.
