Schizophrenia and brain chemistry
Two neurotransmitters that are needed for brain function are dopamine and serotonin, which play a crucial role in emotional health.
Many scientists believe that too much dopamine in certain parts of the brain can cause symptoms such as hallucinations and delusions. Sometimes these symptoms are referred to as the “positive symptoms” of Schizophrenia.
Too little dopamine in other parts of the brain can cause symptoms such as a lack of emotion, lack of energy, and lack of motivation. These symptoms are often called the “negative symptoms” of Schizophrenia.
