Building on evidence for the biological roots of psychological disorders, modern research focuses on several key areas. A primary goal is genetic research, which aims to identify specific genes and mutations that confer risk for mental illness. Another major avenue is the use of sophisticated neural imaging technologies to detect and understand abnormalities in brain structure and function associated with various disorders. Additionally, significant advances in neurochemistry have allowed for deeper investigation into how neurotransmitters and hormones are connected to the development and symptoms of psychopathology.
