A new study brings new knowledge of structural changes in the brain associated with psychosis a condition usually accompanied by chronic antisocial and violent behavior.
An international research team, from well-known institutions in Germany and the United States, has used advanced neuro-imagemental techniques in combination with Atlas Julich of the Brain to analyze which regions of the brain differ in people with psychopathic traits, writes SciTechDaily.
This study included 39 men diagnosed with psychopaths, who were compared to a similar age - control group and other characteristics. Researchers used the psychopathic Control List (PCL-R), a popular instrument that separates psychopathic traits into two main categories: Interpersonial and effective features (such as lack of empathy and pathological lies) and antisocial behavior and life-style deviate, the AP broadcasts, Periscope.
The results showed that participants with stronger signs of antiSocial behavior had a reduced volume in various areas of the brain, including subcotical structures such as basic spectres, thalamus, and the base area of the brain, as well as parts of the middle brain, cerbell, and regions of the Orbitropal cortex and insulin. These parts are involved in important functions such as emotional adjustment, impulse control, decision making, and social behavior.
Meanwhile, the links between the interpersonial traits of psychosis and the changes in the brain were weaker and more variable from person to person. Some changes were noted in the Orbitroporal cortex, dorsolatal frontal, and the left hippocampus, but without a clear and common pattern.
The study also found an overall reduction of brain volume in psycho-agents, with special changes in right-wing subculum, a part of the hippocampus playing a key role in memory processes.
The authors of the study point out that these findings provide solid evidence of a neurobiological link between antisocial behavior and structural changes in the human brain.
