Psychopath brains differ even from ASPD

Reuters reports on how the brains of psychopathic criminals show distinctly less grey matter in the areas of the brain important for understanding the emotions of others.  These differences in brain structure were different even from other criminals who were diagnosed with antisocial personality disorder (ASPD).  Other interesting selections from the article:

• Damage to these areas is linked with a lack of empathy, a poor response to fear and distress and a lack of self-conscious emotions such as guilt or embarrassment.
• Research shows that most violent crimes are committed by a small group of persistent male offenders with ASPD. . . . Such people typically react in an aggressive way to frustration or perceived threats, but most are not psychopaths, the researchers wrote in a summary of their study, which was published in the Archives of General Psychiatry journal.
• There are clear behavior differences among people with ASPD depending on whether they also have psychopathy. Their patterns of offending are different, suggesting the need for a separate approach to treatment.
• "We describe those without psychopathy as 'hot-headed' and those with psychopathy as 'cold-hearted'," Blackwood explained.

I love that distinction between "hot-headed" and "cold-hearted."  I'm going to have to start using those terms all of the time when explaining about how I don't quite consider myself to have ASPD.  And our buddy Bob Hare should be happy about this seeing as he is always going on about how the two are quite distinct.
