Biological psychopathology attempts to explain psychiatric disorders using multiple levels of analysis from the genome to brain functioning to behavior. Although closely related to clinical psychology, it is fundamentally an interdisciplinary approach that attempts to synthesize methods across fields such as neuroscience , psychopharmacology ...
Risk factors for mental illness include psychological trauma, adverse childhood experiences, genetic predisposition, and personality traits. [7] [8] Correlations between mental disorders and substance use are also found to have a two way relationship, in that substance use can lead to the development of mental disorders and having mental disorders can lead to substance use/abuse.
A huge amount of research has been carried out within the framework of the medical model and this has greatly increased our understanding of the possible biological factors underpinning psychological disorders. However, much of the evidence is inconclusive and findings can be difficult to interpret.
In the biological tradition, psychological disorders are attributed to biological causes. In the psychological tradition, disorders are attributed to faulty psychological development, and to social context. [2]: 26 The medical or biological perspective holds the belief that most or all abnormal behavior can be attributed to a medical factor ...
The p factor is modelled in the Hierarchical Taxonomy of Psychopathology. Although researchers initially conceived a three-factor explanation for psychopathology generally, subsequent study provided more evidence for a single factor that is sequentially comorbid, recurrent/chronic, and exists on a continuum of severity and chronicity. [15]
Biological psychiatry or biopsychiatry is an approach to psychiatry that aims to understand mental disorder in terms of the biological function of the nervous system.It is interdisciplinary in its approach and draws on sciences such as neuroscience, psychopharmacology, biochemistry, genetics, epigenetics and physiology to investigate the biological bases of behavior and psychopathology.

Furthermore, in all animals, the nervous system is the organ of behavior. Therefore, every biological and behavioral variable that influences behavior must go through the nervous system to do so. Present-day research in behavioral neuroscience studies all biological variables which act through the nervous system and relate to behavior. [10]
