APPsych AntiSocial Personality Disorder.

Transcript of APPsych AntiSocial Personality Disorder.
Many crimenals have been diagnosed
with this disorders, and many con-men, serial, and spree killers have been known to have this disorder. One of the first prominent researchers in the field was french physician Phillipe Pinel, who in 1806, noticed some symptons of his patients involving impulsive and damaging behavoir, without any signs of remorse. He coined the term, "la folie raisonnante" (insane without delirium.) James Cowles Prichard borrowed some of Pinel’s findings and coined the term moral insanity and in the 21st century it was changed into antisocial personality disorder. Nature VS nurture Biology of Sociopaths Scientists from the MRC Cognition and Brain Sciences Unit and the University of Cambridge used functional magnetic resonance imaging (fMRI) to measure and analyse the brain activity of teenage boys with either childhood-onset or adolescence-onset CD while they were shown images of angry, sad and neutral faces.
Teenagers showed very similar patterns of brain abnormality compared with teenagers without it. The scans showed less activity in the areas of the brain responsible for processing emotions in both types of CD. This may explain why teenagers with CD are insensitive to the distress of others and to social signals of aggression. The scientists also found that the more severe the aggression and antisocial behaviour in the teenagers, the greater the level of brain abnormality.
The study comprised 75 males aged 16-21 years old who were categorised in three groups: 27 individuals with childhood-onset conduct disorder, 25 with adolescence-onset conduct disorder and 23 healthy males as a control group. Twin Studies Studies In Denmark make discovery that identical twins were more likely to show correlations with antisocial behavoir than fraternal (51% compared to 30%).
Also, twins reared apart had tendencies to have correlations with antisocial behavoir. Chemicals of antisocial behavoir One project, carried out in a Romanian orphanage by Prof Mary Carlson, of Harvard Medical School, found lack of physical affection may cause an abnormal release of cortisol, the stress hormone that stunts physical stature and mental abilities, and may lead to agressive tendencies. Other Disorders associated with ASPD Narcassitic personality disorder
Schizophrenia Macdonald triad These behavioral characteristics are found in the childhood histories of individuals with sociopathic behavior:
1. Enuresis (bedwetting)
3. Torturing small animals
It was first identified by a forensic psychiatrist, John Marshall Macdonald in a 1963 paper in the American Journal of Psychiatry titled "The Threat to Kill". Passing on the genes “The Developmental Interface Between Nature and Nurture: A Mutual Influence Model of Child Antisocial Behavior and Parent Behaviors”:
studied the lives and psychology of adopted children’s upbringing in the adoptive parents’ home.
The study found that there was significant association between the biological parents’ psychological disorders and children’s antisocial behaviors.
it found that children whose biological parents had multiple disorders have a greater risk for showing antisocial behavior than children whose parents only had a single disorder. found that psychopaths may stem from "maternal depression". Mothers do not offer appropriate, affectionate, enviroments. Effects of motherly love Enviromental impact Psychopaths usually are shown to be raised in an area of poverty, in an abusive, unstable household, or with an individual with either an addiction or disorder lack of emotional bonds In foster care and adoption, depriving a young child of a significant emotional bond could damage his ability to form intimate and trusting relationships, which may explain why some adopted children are prone to develop ASP.
As young children, they may be more likely to move from one caregiver to another before a final adoption, and fail to develop sustaining emotional attachments to adult figures. -http://classictriads.com/macdonald-triad Macdoland triad info
i picked this source because it had a accurate definition of the macdonald triad. it explained it's effects and it's causes.
this source explained how attachment may be an underlying reasson for aspd.
the effects of having sustaining relationships may be a cause to how people with aspd cant
form emotional bonds.

this article described how maternal inlgfluences affects people with aspd. it also emphasises
how attachment plays a role in the develpoement of aspd. Lack of Discipline no or inappropriate discipline and lack of supervision have been linked to antisocial behavior in children. antisocial parents often lack the motivation to keep an eye on their children. The importance of parental supervision is also underscored when antisocials grow up in large families where each child gets proportionately less attention.

trouble staying employed and tend to work in menial jobs.Other sources state they often come from unstable families.
As children, they are often abandoned by their fathers and raised by domineering mothers.
They have high rates of suicide attempts.
From an early age, many are intensely interested in voyeurism, fetishism, and sadomasochistic pornography.
They were frequently bullied as children.
Some were involved in petty crimes, such as theft, fraud, vandalism, dishonesty or similar offenses. Motives to kill Visionary- Visionary serial killers suffer from psychotic breaks with reality, sometimes believing they are another person or are compelled to murder by entities such as the Devil or God. The two most common subgroups are "demon mandated" and "God mandated Mission-Oriented- justify their acts by getting rid of a certain type of person they perceive as undesirable, like homosexuals, prostitutes, or people of different ethnicity or religion; however, they are generally not psychotic.Some see themselves as attempting to change society. Hedonistic- seeks thrills and derives pleasure from killing. three subtypes of the hedonistic killer: "lust", "thrill" and "comfort" Power-Control- The main objective for this type of serial killer is to gain and exert power over their victim. abused as children, leaving them with feelings of powerlessness and inadequacy as adults. Female Killers Female serial killers are rare. They tend to murder men for material gain, are usually emotionally close to their victims, and generally need to have a relationship with a person before killing them. The methods they use for murder are low-profile, such as murder by poison (the preferred choice for killing).They commit killings in specific places, such as their home or a health-care facility, or at different locations within the same city or state Cases Jeffrey Dahmer John Wayne Gacy Dennis Nilson Elizabeth Bathory
