(1) On the edge of psychopathy (Jim Fallon admits lack of empathy and care) and (2) Mirror pain and touch synesthesia: people who feel the pain of others


BBC: All in the Mind (1/5/2012)

Professor James Fallon tells Claudia Hammond his tale of self-discovery: a story with some dark and disturbing turns involving psychopaths and brain scans, family skeletons, some very personal genetic revelations and the power of parental love.
Two people who experience mirror-pain and mirror-touch synaesthesia explain what it's like to see someone being hurt and feeling the sensation of pain or touch in the same place themselves. Michael Banissy, a neuropsychologist at University College, London talks about his research on this strange phenomenon. He looked at what's happening in the brains of these people and discovered that they are also extra-empathetic emotionally.

A realistic description of a person with affective empathy disorder

In Siri Hustvedt's novel What I loved  (2003) you can find a fascinating literary description of a person suffering from a serious empathy disorder ("Mark Wechsler").

G. Bedi e.a. (2010): "Is Ecstasy an "Empathogen"? Effects of ±3,4-Methylenedioxymethamphetamine on Prosocial Feelings and Identification of Emotional States in Others"


 

Abstract

Background: Users of ±3,4-methylenedioxymethamphetamine (MDMA), "ecstasy," report that the drug produces unusual psychological effects, including increased empathy and prosocial feelings. These "empathogenic" effects are cited as reasons for recreational ecstasy use and also form the basis for the proposed use of MDMA in psychotherapy. However, they have yet to be characterized in controlled studies. Here, we investigate effects of MDMA on an important social cognitive capacity, the identification of emotional expression in others, and on socially relevant mood states. Methods: Over four sessions, healthy ecstasy-using volunteers (n = 21) received MDMA (.75, 1.5 mg/kg), methamphetamine (METH) (20 mg), and placebo under double-blind, randomized conditions. They completed self-report ratings of relevant affective states and undertook tasks in which they identified emotions from images of faces, pictures of eyes, and vocal cues. Results: MDMA (1.5 mg/kg) significantly increased ratings of feeling "loving" and "friendly", and MDMA (.75 mg/kg) increased "loneliness". Both MDMA (1.5 mg/kg) and METH increased "playfulness"; only METH increased "sociability". MDMA (1.5 mg/kg) robustly decreased accuracy of facial fear recognition relative to placebo. Conclusions: The drug MDMA increased "empathogenic" feelings but reduced accurate identification of threat-related facial emotional signals in others, findings consistent with increased social approach behavior rather than empathy. This effect of MDMA on social cognition has implications for both recreational and therapeutic use. In recreational users, acute drug effects might alter social risk-taking while intoxicated. Socioemotional processing alterations such as those documented here might underlie possible psychotherapeutic benefits of this drug; further investigation of such mechanisms could inform treatment design to maximize active components of MDMA-assisted psychotherapy.

Early prefrontal cortex damage and impairment of moral capacities: a psychopathy-like syndrome


“No behavioral abnormalities were observed until the age of three years, when she was first noted to be largely unresponsive to verbal or physical punishment. Her behavior became progressively disruptive, so much so that, by age 14, she required placement in the first of several treatment facilities. Her teachers considered her to be intelligent and academically capable, but she routinely failed to complete assigned tasks. Her adolescence was marked by disruptive behavior in school and at home (for example, failure to comply with rules, frequent loud confrontations with peers and adults). She stole from her family and from other children and shoplifted frequently, leading to multiple arrests. She was verbally and physically abusive to others. She lied chronically. Her lack of friends was conspicuous. She ran away from home and from treatment facilities. She exhibited early and risky sexual behavior leading to a pregnancy at age 18. Contingency management in residential treatment facilities and the use of psychotropic medication were of no help. After repeatedly putting herself at physical and financial risk, she became entirely dependent on her parents and on social agencies for financial support and oversight of her personal affairs. She did not formulate any plans for her future and she sought no employment. Whenever employment was arranged, she was unable to hold the job due to lack of dependability and gross infractions of rules. Affect was labile and often poorly matched to the situation, but superficial social behavior was unremarkable. She never expressed guilt or remorse for her misbehavior. There was little or no evidence that she experienced empathy, and her maternal behavior was marked by dangerous insensitivity to the infant’s needs. She blamed her misdeeds and social difficulties on other people, and she denied any difficulties with cognition or behavior.”

Neuroscientist James Fallon on the brain of psychopaths and his own brain


Dr. FALLON: And I took a look at my own PET scan and saw something a little disturbing that I did not talk about.
HAGERTY: What he didn’t want to reveal was that his orbital cortex looks inactive.
Dr. FALLON: If you look at the PET scan, I look just like one of those killers.
HAGERTY: Fallon cautions that this is a young field. Scientists are just beginning to understand this area of the brain. Still, he says, the evidence is accumulating that some people’s brains predispose them toward violence, and that psychopathic tendencies may be passed down from one generation to another.
Which brings us to the next part of this family experiment. Along with brain scans, Fallon also tested each family member’s DNA for genes that are associated with violence and impulsivity. He looked at 12 genes and zeroed in on something called the MAOA gene. It’s also known as the warrior gene because it regulates serotonin in the brain.
Serotonin affects your mood, and many scientists believe that if you have a certain version of the warrior gene, your brain won’t respond to the calming effects of serotonin.
Dr. FALLON: So this is the MAO gene. And we can see here my daughter, son, daughter, daughter, brother, brother, wife, brother.
HAGERTY: Everyone in his family has the low aggression variant, except…
Dr. FALLON: I’m like 100 percent here. I have the pattern, a risky pattern. In a sense, I’m a born killer.
