Bipolar disorder is a mental illness in which two psychopathological states are experienced alternately – apathy and euphoria (we then speak of a depressive phase and a manic phase).
One of the neurotransmitters – dopamine – is responsible for the occurrence of euphoria. This substance is associated with people's feelings of happiness and joy. These feelings appear when dopamine is increased in the structures of the central nervous system. The fact that dopamine works in a “euphorizing” way is proven by the fact that people who have its deficiencies may not be able to feel happiness and joy.
Mood changes range from extreme sadness to extreme joy. In the euphoric phase, patients suddenly become reckless and unceremonious. They then make risky and thoughtless decisions, and their rationalization ability decreases. They may also need contact with people. It also happens that outbursts of aggression accompany euphoria in bipolar disorder.
