Serotonin syndrome is caused by an excessive amount of serotonin in a person’s system. Serotonin is a neurotransmitter and hormone also known as the “happiness hormone.” It is given this name because it is the hormone that makes us feel happy, reduces pain sensations, and is also used as a reward by the brain to encourage survival-related behaviors such as eating, exercising, and having sex. Overall, serotonin is a very positive hormone.
