Dopamine regulates mood, muscle movement, and nerve control. It plays a vital role in the brain’s pleasure and achievement system. Excessive dopamine could negatively affect your brain, decreasing the desire to complete difficult tasks such as writing or reading. Such imbalances in dopamine could lead to mental health problems such as depression. Serotonin is just another neurotransmitter present in the brain. Its purpose is to regulate your mood, sleep cycle, body temperature, and hormonal activity. In addition to regulation, serotonin aides digestion. An imbalance in serotonin could also lead to mental health problems such as depression. Dopamine and serotonin both play a vital role in regulating and maintaining homeostasis. But excessive amounts of dopamine and serotonin could lead to an addictive personality.
