Sociopaths

The relationship between diverse early traumatic events and psychopathy was studied in 194 male inmates. Criminal history transcripts were revised, and clinical interviews were conducted to determine the level of psychopathy using the Psychopathy Checklist-Revised (PCL-R) Form, and the Early Trauma Inventory was applied to assess the incidence of abuse before 18 years of age. Psychopathic inmates presented a higher victimization level and were more exposed to certain types of intended abuse than sociopathic inmates, while the sum of events and emotional abuse were associated with the PCL-R score...

The maintenance of appropriate social behavior is a very complex process with many contributing factors. Social and moral judgments rely on the proper functioning of neural circuits concerned with complex cognitive and emotional processes. Damage to these systems may lead to distinct social behavior abnormalities. When patients present with dysmoral behavior for the first time, as a change from a prior pervasive pattern of behavior, clinicians need to consider a possible, causative brain disorder. The aim is to explore sociopathy as a manifestation of dementia...

Although anecdotal case accounts suggest that evidence concerning Antisocial Personality Disorder (APD), sociopathy and psychopathy is frequently introduced by the prosecution in capital murder trials, to date there has been no systematic research to determine the actual prevalence, role, or perceived impact of such evidence in these cases. Survey data collected from attendees at a national capital mitigation conference (n=41) indicated that prosecution evidence concerning APD was quite prevalent, with "sociopath" and "psychopath" labels being introduced less frequently...

Theoretical models of public stigma toward mental illness have focused on factors that perpetuate stigma toward the general label of "mental illness" or toward a handful of specific illnesses, used more or less interchangeably. The current work used the Stereotype Content Model (Fiske, Cuddy, Glick, & Xu, 2002) to examine how one facet of public stigma--stereotype content--differs as a function of specific mental illnesses. Participants were recruited online from across the U.S. Study 1 demonstrated that the overarching category of people with mental illness was perceived as relatively incompetent, but not very hostile (i...

Individuals who engage in corrupt and immoral behavior are in some ways similar to individuals with psychopathy. Normal people refrain from engaging in such behaviors because they tie together the moral value of society and the risk of punishment when they violate social rules. What is it, then, that allows these immoral individuals to behave in this manner, and in some situations even to prosper? When there is a dysfunction of somatic markers, specific disadvantageous impairments in decision-making arise, as in moral judgment, but, paradoxically, under some circumstances, the damage can cause the patient to make optimal financial investment decisions...

Although well-known from head trauma and acute strokes, sociopathic behavior from dementia is less known and understood. This study reviewed 33 dementia patients who had been in trouble with the law. They were divided into two groups: 22 who committed impulsive sociopathic acts and 11 who committed non-impulsive acts. The impulsive patients demonstrated nonviolent acts, such as disinhibited sexual behavior or pathological stealing, and had disproportionate frontal-caudate atrophy on neuroimaging. The majority of non-impulsive patients demonstrated agitation-paranoia, sometimes with reactive aggression, delusional beliefs, or aphasic paranoia, and had advanced memory and other cognitive impairment...

Poor insight is a ubiquitous phenomenon in psychosis with great repercussions on clinical practise and the outcomes of patients. Poor insight comprises "state" and "trait" components. This paper targeted predictors of global insight and insight dimensions at baseline in the drug-naïve status of first-episode psychosis patients and during a 6-month follow up after episode remission. Seventy-seven consecutive and previously unmedicated patients with first-episode schizophrenia-spectrum disorders (FESSD) completed baseline and 6-month insight, premorbid, symptomatological and neuropsychological assessments...

BACKGROUND: Insight in psychosis and schizophrenia is considered a complex biopsychosocial phenomenon. Premorbid personality is regarded by some authors as part of the substrate to many psychiatric phenomena, but it is not clear if this applies to insight. AIM: To examine longitudinal relationships between personality traits and insight dimensions in first-episode psychosis. METHODS: One hundred consecutive antipsychotic-naïve first-episode nonaffective psychotic patients admitted to hospital were included in the study...

Brain disorders can lead to criminal violations. Patients with frontotemporal dementia (FTD) are particularly prone to sociopathic behavior while retaining knowledge of their acts and of moral and conventional rules. This report describes four FTD patients who committed criminal violations in the presence of clear consciousness and sufficiently intact cognition. They understood the nature of their acts and the potential consequences, but did not feel sufficiently concerned to be deterred. FTD involves a unique pathologic combination affecting the ventromedial prefrontal cortex, with altered moral feelings, right anterior temporal loss of emotional empathy, and orbitofrontal changes with disinhibited, compulsive behavior...

This study was designed to assess the baseline noradrenergic turnover of subgroups of postwithdrawal abstinent alcoholics and healthy controls. The method chosen was an overnight fasting urine sample of the breakdown product of norepinephrine, MHPG, related to urinary creatinine. A comparison was made with platelet monoamine oxidase activity and also within subgroups of the study population. This study found no difference between alcoholics and controls, nor between subgroups of postwithdrawal alcoholics in their level of urinary MHPG corrected for creatinine, and no significant correlation with major subject characteristics or with platelet monoamine oxidase...

Morality may be innate to the human brain. This review examines the neurobiological evidence from research involving functional magnetic resonance imaging of normal subjects, developmental sociopathy, acquired sociopathy from brain lesions, and frontotemporal dementia. These studies indicate a "neuromoral" network for responding to moral dilemmas centered in the ventromedial prefrontal cortex and its connections, particularly on the right. The neurobiological evidence indicates the existence of automatic "prosocial" mechanisms for identification with others that are part of the moral brain...

Almost everything you know about heroin addiction is wrong. Not only is it wrong, but it is obviously wrong. Heroin is not highly addictive; withdrawal from it is not medically serious; addicts do not become criminals to feed their habit; addicts do not need any medical assistance to stop taking heroin; and contrary to received wisdom, heroin addiction most certainly is a moral or spiritual problem. A literary tradition dating back to De Quincey and Coleridge, and continuing up to the deeply sociopathic William Burroughs and beyond, has misled all Western societies for generations about the nature of heroin addiction...

The purpose of this study is to attempt to indicate a possible process by which a sociopathic personality emerges. It is contended that sociopathic behavior can be understood in relation to the emergence of the self and the concomitant ability to take the role of the other. For the purposes of this study the sociopath is conceptualized as one who is deficient in role-taking ability, that is, he is unable to judge his own behavior from the viewpoint of another person. The socialization process is considered crucial in the emergence of the self and the ability to take the role of the other...

BACKGROUND: A dysfunction in brain serotonin turnover is a well-established factor associated with the impulsive and sociopathic behavior in alcoholics. The conjuncted alterations in functioning of serotonin transporter (SERT) may play a role in the regulation of emotional balance, judgement, and the adverse behavioral effects of ethanol misuse. These traits may be related to serotonergic regulation in the amygdala and prefrontal cortex. METHODS: The binding of [(3)H]citalopram to SERT was evaluated in the amygdala of Cloninger type 1 and 2 alcoholics (n = 17), and nonalcoholic control subjects (n = 10) by postmortem whole-hemisphere autoradiography...

A 130-item personality inventory (the Psychological Screening Inventory, Lanyon, 1970) was used to obtain a novel measure of perseveration coupled with affirmative set. Acquiescent Perseveration (AP), a quantitative behavioral metric, is the sum of the lengths of True (T) response runs 4 and longer, doubling T runs 9 and longer. With male subjects, a one-way ANOVA comparison of heterogeneous organics with five non-organic control groups (normals, neurotics, sociopaths, personality disorders, and schizophrenics) showed mean AP differences greater than ...

OBJECTIVE: To investigate the basis of disturbed moral judgment in patients with frontotemporal dementia (FTD). BACKGROUND: FTD is characterized by difficulty in modulating social behavior. Patients lack social propriety and may perform sociopathic acts. In addition, FTD patients often lack empathy for others. These findings suggest alterations in the nature of morality in patients with FTD. METHOD: We administered an inventory of moral knowledge and two moral dilemmas to 26 patients with the frontal variant of FTD, 26 patients with Alzheimer disease (AD), and 26 normal control subjects...

AIMS: To establish an alcohol-dependent drinker's clinical typology, based on patients attending the Alcoholism Unit of Santa Maria's General Hospital in Lisbon, Portugal. METHODS: A multivariate statistical analysis was used to extract the typology solution. RESULTS: We obtained five factors: Anxiopathic, typifies anxious functioning; Heredopathic, congregates familiar and genetic influences on alcoholism; Thimopathic, typified by affective symptomatology; Sociopathic, characterized by disruptive behaviours under alcohol influence; and Adictopathic, isolates younger individuals who consume alcohol and other types of psychoactive substances...

As human society is mainly cooperative, it is not clear how antisocial personality disorder (APD) persists. The current explanation is that sociopaths are cheaters who maximize their fitness by taking advantages from others. Although this argument is valid, we show here that society also benefits from APD. We propose that the old phylogeny of punishment, the fact of being a full member of society, the frequency of the disorder, genetics, linkage between two "contradictory" DSM IV criteria for the disorder, and the necessity for society to fight against antisocial behavior, play positive roles for society and/or human groups, especially in the ancestral environment...

BACKGROUND: It is not understood why some patients with frontotemporal dementia (FTD) manifest sociopathic behavior. OBJECTIVE: To examine the prevalence and characteristics of sociopathic behavior in FTD patients as compared to those with Alzheimer's disease (AD). METHODS AND PARTICIPANTS: We surveyed a group of FTD patients and a group of AD patients for sociopathic behavior, evaluated the characteristics surrounding their acts, and compared the groups on neuropsychological tests and functional neuroimaging...
