Biological psychiatry also called as biopsychiatry is a field in biochemistry and an approach used by psychiatry for better understanding of mental disorders with specific attention to biological functions performed by the nervous system. Biological psychiatry is the study of drugs that affect minds and involves not only biochemistry but also pharmacology, neuroscience, physiology and genetics. All these fields help to form theories that help to comprehend the biological basis of psychopathology as well as abnormal behaviors.

Biological psychiatry generally focuses upon behavioral disorders in which the nervous system pathology is visible such as neuritis, cerebral palsy, epilepsy, encephalitis, multiple sclerosis and Parkinson’s disease. Biological psychiatry at times overlaps with neurology and the approach neuropsychiatry which deals with the behavioral disturbances in terms if obvious brain disorder. Biological psychiatry term and research papers are mostly written in Vancouver style but can also be written in CSE/CBE Style and ACS writing styles depending upon the required word sizes and related specifications.

Biological psychiatry and associated approaches to mental disorders mostly overlap each other. Biological psychiatry is particularly significant in the developing and prescribing of drug based interventions for mental illnesses as biological psychiatry exclusively deals with the understanding of biological function. Psychiatrists usually prescribe not only drug intervention in practice but psychological therapies for effective treatment. Biological psychiatry has been practiced since ancient Greeks but the specific term of Biological psychiatry came into use in a 1953 peer-reviewed literature. This term is less popular in U.K than in the U.S.
