Neurobiologically spoken, the supstrate of the mind is formed by neuronal networks, and dysregulated neurocircuitry can cause psychiatric disorders. Psychiatric disorders are diagnosed by symptom clusters that are the result of abnormal brain tissue, and/or activity in specialized areas of the brain. Dysregulated circuitry results from abnormal neural function, or abnormal neural connections from one brain area to another, which leads to neurotransmitter imbalances. Each psychiatric disorder has uniquely dysregulated circuitry and thereby unique neurotransmitter imbalance, such as: prefrontal cortical-limbic pathways in depression or prefrontal cortical-striatal pathways in schizophrenia ie. serotonin-norepinephrin-dopamin imbalance in depression, or dopamine hyperactivity in schizophrenia. Biological psychiatry has completely changed the farmacological treatment of psychiatric disorders, and new foundings in that field are supportive to futher more neuropsychopharmacological and nonpharmacological therapy studies, whish has as a result more safe and effective therapy for psychiatric disorders.
