Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: To test the hypothesis that cerebrospinal fluid (CSF)/ serum albumin ratios are increased in violent offenders. SUBJECTS AND METHODS: In a previous study of violent offenders, we found significantly higher CSF/serum album ratios (as a sign of increased blood-brain barrier permeability) in violent offenders than in healthy controls. For the present replication study, we recruited a new group of 28 violent offenders, aged 45 years or younger, and 20 new control subjects. RESULTS: The albumin ratio was again significantly higher in the offender group (mean 6.2) than in the control group (mean 4.6) (P = 0.012). Substance abuse or current medication did not appear to explain this finding. CONCLUSION: Increased CSF/serum albumin ratios are an unspecific sign of neurological dysfunction in subgroups of violent offenders.

Ingår i: Psychiatry research. - : Elsevier BV. - 0165-1781 .- 0925-4927 .- 1872-7123. ; 156:1, s. 87-90

Tidskriftsartikel (refereegranskat)abstract
- Since cross-sectional brain-imaging studies demonstrating frontotemporal cerebral hypoactivity in violent offenders have generally been carried out around the time of trial and sentencing, the findings might be influenced by the stressful situation of the subjects. It seems that no group of offenders with this finding has yet been followed longitudinally. We have re-examined nine offenders convicted of lethal or near-lethal violence in whom single photon emission tomography (SPECT) previously had demonstrated frontotemporal hypoperfusion. The mean interval between the initial and the follow-up examination was 4 years. The initially observed hypoactivity was found to have remained virtually unchanged at follow-up: no mean change in the group exceeded 5% in 12 assessed regions of interest. Although preliminary due to the small sample size, this study suggests that frontotemporal brain hypoactivity is a trait rather than a state in perpetrators of severe violent crimes.

Tidskriftsartikel (refereegranskat)abstract
- Attempting to avoid some of the most common methodological problems involved in research on sexual child abuse, we collected data on crimes, perpetrators, and sanctions in all convicted cases of sexual child abuse in a defined population during a 5-year period. This approach provided amply documented and ascertained cases with precise definitions and descriptions of the crimes involved, no clinical referral bias, and minimal dependence on memory effects. The results are valid for the small proportion of cases that lead to conviction in the context of Swedish legislation. Structured data were collected from the court dossiers in all cases of sexual crimes against minors (less than 15 years of age) tried and sentenced at the courts in the Västra Götaland region of Sweden between 1993 and 1997. The total number of 496 sentences for sexual crimes during the study period included 203 cases of sexual child abuse (40.8%) with 283 victims and 196 perpetrators, all men. Girls were victims in 85% of the cases, boys in 12%, and boys as well as girls in 3%. Sexual penetration had occurred in 54.5% of cases and the total proportion of hands-on crimes was 83%. Most perpetrators, 72%, were well known to the child. The most severe offenses took place within the family. A wide range of acts were classified as sexual child abuse, but most common was sexual penetration of a female child by her biological father or a family friend.

Age at onset of substance abuse: a crucial covariate of psychopathic traits and aggression in adult offenders.
- 2007

Ingår i: Psychiatry research. - : Elsevier BV. - 0165-1781 .- 1872-7123. ; 153:2, s. 195-8
-
Tidskriftsartikel (refereegranskat)abstract
- To examine age at onset of substance abuse in relation to other factors of relevance to criminal behavior, we compared Life History of Aggression (LHA) scores, traits of psychopathy according to the Psychopathy Checklist--Revised (PCL-R), and violent recidivism in 100 violent offenders with early (before the age of 18) versus late onset of abuse or dependence. Of 56 subjects with a history of alcohol and/or drug abuse, an early onset was ascertained in 31. The duration of abuse did not correlate with the LHA and PCL-R scores or with violent recidivism, but the age at onset correlated strongly with all these factors and also remained their strongest correlate in multivariate models including childhood-onset attention deficit/hyperactivity disorder, conduct disorder, and drug abuse as covariates. Strong mathematical associations with aggression, psychopathy, and recidivism pointed to age at onset of substance abuse as a marker of possible complications that require preventive social, educational and medical measures.

Tidskriftsartikel (refereegranskat)abstract
- Aims: This prospective study was designed to replicate previous findings of an association between the platelet monoamine oxidase B (MAO-B) activity and factors of relevance for criminal behaviour in a well-documented clinical study population. Methods: Subjects (n = 77, aged 17-76 years, median 30 years) were recruited among consecutive perpetrators of severe interpersonal violent and/or sexual crimes referred to forensic psychiatric investigation. Participants were extensively investigated by structured psychiatric, psychological and social workups, including state-of-the-art rating instruments and official records, and with laboratory tests including venous blood sampling for determination of MAO-B activity. A subset of 36 individuals had lumbar punctures to measure cerebrospinal fluid concentrations of monoamine neurotransmitter metabolites. Results: Platelet MAO-B activity did not show any significant correlation with assessments of childhood behavioural disorders, substance abuse, or psychosocial adversity, nor with any crime-related factors, such as scores on the Life History of Aggression Scale, the Psychopathy Checklist or recidivistic violent crime. No significant correlation was found between MAO-B and any of the monoamine metabolites. Analyses in subgroups of smokers/non-smokers did not change this overall result. Conclusions: The findings of the present study did not support the use of MAO-B as a biological marker for aggression-related personality traits or as a predictor for violent recidivism among violent offenders.

Life History of Aggression scores are predicted by childhood hyperactivity, conduct disorder, adult substance abuse, and low cooperativeness in adult psychiatric patients.

Tidskriftsartikel (refereegranskat)abstract
- The prevention of aggressive behaviours is a core priority for psychiatric clinical work, but the association between the diagnostic concepts used in psychiatry and aggression remains largely unknown. Outpatients referred for psychiatric evaluations of childhood-onset neuropsychiatric disorders (n = 178) and perpetrators of violent crimes referred to pre-trial forensic psychiatric investigations (n = 92) had comprehensive, instrument-based, psychiatric assessments, including the Life History of Aggression (LHA) scales. Total and subscale LHA scores were compared to the categorical and dimensional diagnoses of childhood and adult DSM-IV axis I and II mental disorders, general intelligence (IQ), Global Assessment of Functioning (GAF), and personality traits according to the Temperament and Character Inventory (TCI). Overall, the two groups had similar LHA scores, but the offender group scored higher on the Antisocial subscale. Higher total LHA scores were independently associated with the hyperactivity facet of attention-deficit/hyperactivity disorder (AD/HD), childhood conduct disorder, substance-related disorders, and low scores on the Cooperativeness character dimension according to the TCI. IQ and GAF-scores were negatively correlated with the LHA subscale Self-directed aggression. Autistic traits were inversely correlated with aggression among outpatients, while the opposite pattern was noted in the forensic group. The findings call for assessments of aggression-related behaviours in all psychiatric settings.

Early Criminal Recidivism Among Mentally Disordered Offenders.
- 2012
-
Ingår i: International journal of offender therapy and comparative criminology. - 1552-6933.
-
Tidskriftsartikel (refereegranskat)abstract
- Criminal recidivism was studied during 2 years in a Swedish population-based cohort (N = 318) of mentally disordered male offenders who had undergone a pretrial forensic psychiatric investigation, been convicted in subsequent trials, and been sentenced to forensic psychiatric treatment (FPT; n = 152), prison (n = 116), or noncustodial sanctions (n = 50). Recidivism was analysed in relation to index sanctions, levels of supervision, diagnoses, and criminological factors. Significantly lower recidivism in the FPT group was related to lower crime rates during periods at conditional liberty in this group alone, and recidivism was significantly more common among offenders with at least one of the two diagnoses of substance abuse disorder and personality disorder than among those with psychotic or other mental disorders alone. Age at index crime and number of previous crimes emerged as significant predictors of recidivism. The results of this study suggest that the relapse rates depend as much on level of supervision as on individual characteristics.

Tidskriftsartikel (refereegranskat)abstract
- Objective: To describe criminal recidivism, especially violent recidivism, in a long-term follow-up of mentally disordered offenders sentenced to different types of sanctions. Subjects and methods: A population-based Swedish cohort of male offenders referred to pre-trial psychiatric investigations between 1988 and 1995, was sentenced to forensic psychiatric treatment (n = 163), prison (n = 120), or noncustodial sanctions (n = 52). They were followed from the beginning of their sanctions until the end of June, 2008, through official health and crime registers. Survival analyses were used to compare time until violent recidivism across different sanctions and mental disorders, and predictors of violent recidivism were investigated using univariate comparisons, a multivariate Cox regression analysis and Receiver Operating Characteristic (ROC) curves. Finally, all criminal reconvictions until the end of follow-up were assessed (a total time period of 13 to 20 years). Results: Forty-seven percent of all subjects were reconvicted for violent crimes during follow-up. There were no significant differences between sanction groups. By contrast, diagnostic groups that included substance abuse had significant effects, and stood out as the strongest predictor of violent reconvictions together with the number of previous violent crimes, and age at the first registered criminal offence. Variables identified in the multivariate model together predicted violent recidivism with an area under the ROC curve of 0.72, while the corresponding figure for the age at onset of criminality as the sole predictor was 0.71. Among the different sanction forms for different time periods, time in hospital and prison were significantly less associated with violent recidivism compared to time in conditional release/probation.

Tidskriftsartikel (refereegranskat)abstract
- Rates of recidivism and types of recidivist crime have varied greatly in follow-up studies of child sexual abusers. In this long-term study of a population-based cohort (n = 193) and a nationwide clinic-referred study group (n = 166) of child sexual abusers, rates of recidivism and associations between index descriptors and outcomes were compared between intra-familial offenders and extra-familial offenders. Overall, 9.8% relapsed into sexual offence, 12.4% relapsed into violence and 2.6% relapsed into both types of offences in the population-based cohort. Corresponding numbers for the clinic-referred group were 13.9, 10.8 and 4.2%. Extra-familial offenders at index were significantly more likely to relapse into both sexual and violent criminality than intra-familial offenders, but no differences were found in rates of hands-off and hands-on crimes. Analysis of receiver operating characteristics showed that age at first conviction predicted sexual, violent and any criminality, with areas under the curve ranging from .67 to .80.

- Neurobiological markers in cerebrospinal fluid (CSF) and in serum, previously found to co-vary with destructive personality traits in violent offenders, were explored in a general population sample of 21 patients undergoing knee surgery. Results on the Karolinska Scales of Personality (KSP) and the Temperament and Character Inventory (TCI) were compared with CSF/serum albumin ratios and serum concentrations of beta-trace protein (beta TP) (as markers for blood-brain barrier (BBB) permeability), to CSF/serum albumin ratios between the dopamine and serotonin metabolites homovanillic acid (HVA)/5-hydroxyindoleacetic acid (HIM) and to CSF and serum ratios between activated thyroid hormone (T3) and its precursor T4. Serum beta TP concentrations correlated with CSF/serum albumin ratios (P=0.018), but not with preoperative serum creatinine concentrations. Serum beta TP correlated significantly with Monotony Avoidance and Impulsiveness: CSF HVA/5-HIAA ratios with Irritability and low Cooperativeness. The beta TP is a potential serum marker for the integrity of the BBB that does not necessitate lumbar puncture. Thyroid hormones did not correlate with personality traits. As reported in forensic psychiatric patients, aggressive, unempathic personality traits were thus associated with increased dopaminergic activity in relation to the serotonergic activity and impulsivity to increased BBB permeability also in a general population group.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- The development of forensic psychiatric risk assessments is discussed from a clinical point of view using the example of Sweden. A central task in forensic psychiatry has traditionally been to identify dangerous, mentally disordered subjects considered to be prone to commit violent acts. Over time, “dangerousness” has been reworded into “risk”. Nevertheless, such assessments have generally been based on the psychiatric factors characterising the individual patient, while group interaction, situational factors, or social and cultural circumstances, such as the availability of alcohol and drugs, have been largely overlooked. That risk assessments have a focused on people with a diagnosis of “mental disorder” and been used as grounds for coercive measures and integrity violations has somehow been accepted as a matter of course in the public and political debate. Even the basic question whether offenders with a mental disorder are really more prone to criminal recidivism than other offenders seems to have been treated light-handedly and dealt with merely by epidemiological comparisons between groups of persons with broad ranges of psychosocial vulnerability and the general population. Legal texts, instructions and guidelines from the authorities in charge are often vague and general, while actors in the judicial system seem to put their trust in psychiatric opinions. The exchange of professional opinions, general public expectations, and judicial decision processes poses a huge risk for misunderstandings based on divergent expectations and uses of terminology.

Mentally disordered criminal offenders in the Swedish criminal system
- 2010

Ingår i: International Journal of Law and Psychiatry. - : Elsevier BV. - 0160-2527. ; 33:4, s. 220-226
-
Tidskriftsartikel (refereegranskat)abstract
- Historically, the Swedish criminal justice system conformed to other Western penal law systems, exempting severely mentally disordered offenders considered to be unaccountable. However, in 1965 Sweden enforced a radical penal law abolishing exceptions based on unaccountability. Mentally disordered offenders have since then been subjected to various forms of sanctions motivated by the offender's need for care and aimed at general prevention. Until 2008, a prison sentence was not allowed for offenders found to have committed a crime under the influence of a severe mental disorder, leaving forensic psychiatric care the most common sanction in this group. Such offenders are nevertheless held criminally responsible, liable for damages, and encumbered with a criminal record. In most cases, such offenders must not be discharged without the approval of an administrative court. Two essentially modern principles may be discerned behind the “Swedish model”: first, an attempted abolishment of moral responsibility, omitting concepts such as guilt, accountability, atonement, and retribution, and, second, the integration of psychiatric care into the societal reaction and control systems. The model has been much criticized, and several governmental committees have suggested a re-introduction of a system involving the concept of accountability. This review describes the Swedish special criminal justice provisions on mentally disordered offenders including the legislative changes in 1965 along with current proposals to return to a pre-1965 system, presents current Swedish forensic psychiatric practice and research, and discusses some of the ethical, political, and metaphysical presumptions that underlie the current system.

- Changes in the metabolism of tryptophan, other amino acids, and steroid hormones have been implicated in aggression. We compared tryptophan, competing long amino acids (CAAs), and cortisol in serum (S) and CSF in 22 violent offenders and 15 healthy controls. Offenders had significantly increased S-L-tryptophan, S-free tryptophan, S-CAAs, S-cortisol and CSF-cortisol, indicating abnormal neurophysiological processes. Larger studies on the interplay between violence, serotonin precursors, and stress hormones need to integrate personality traits, life situations, and physiological adaptation.

Tidskriftsartikel (refereegranskat)abstract
- To describe lifetime mental disorders among perpetrators of severe inter-personal crimes and to identify the problem domains most closely associated with aggression and a history of repeated violent criminality, we used structured interviews, clinical assessments, analyses of intellectual functioning, medical and social files, and collateral interviews in 100 consecutive subjects of pretrial forensic psychiatric investigations. Childhood-onset neuropsychiatric disorders [attention-deficit/hyperactivity disorder (AD/HD), learning disability, tics and autism spectrum disorders] affected 55% of the subjects and formed complex comorbidity patterns with adult personality disorders [including psychopathic traits according to the Psychopathy Checklist (PCL-R)], mood disorders and substance abuse. The closest psychiatric covariates to high Lifetime History of Aggression (LHA) scores and violent recidivism were the PCL-R scores and childhood conduct disorder (CD). Behavioral and affective PCL-R factors were closely associated with childhood AD/HD, CD, and autistic traits. The results support the notion that childhood-onset social and behavioral problems form the most relevant psychiatric symptom cluster in relation to pervasive adult violent behavior, while late-onset mental disorders are more often associated with single acts of violent or sexual aggression.

- We assessed a total range of peripheral thyroid hormone fractions, binding globulins, and thyroid-active antibodies in 37 medication-free, violent or sexual offenders, aged 17-45 years, to describe possible mechanisms involved in the thyroid metabolism of aggressive men. The ratio between T3 and T4 correlated with ratings of psychopathy, indicating increased peripheral deiodination as a biological covariate to callous personality traits. Autoimmune antibodies, hepatic failure, abnormal binding globulins, or substance abuse did not affect the association.

Reduced frontotemporal perfusion in psychopathic personality.

Tidskriftsartikel (refereegranskat)abstract
- Several brain-imaging studies have found associations between aberrant functioning in the frontal and temporal lobes and violent offending. We have previously reported decreased frontotemporal perfusion unrelated to psychosis, substance abuse, or current medication in 21 violent offenders. In the present study, we compared the regional cerebral blood flow (rCBF) in a new group of 32 violent offenders to scores on the Psychopathy Checklist-Revised (PCL-R), which rates two aspects of psychopathy: disturbed interpersonal attitudes (Factor 1) and impulsive antisocial behavior (Factor 2). A recently proposed model has split Factor 1 into a new Factor 1 (deceitful interpersonal style), a new Factor 2 (affective unresponsiveness), and a Factor 3, which approximately corresponds to the old Factor 2. The rCBF was assessed by single-photon emission computed tomography (SPECT) with technetium-99m-d,l-hexamethylpropyleneamine oxime (HMPAO) in regions of interest (ROIs) placed in accordance with fusioned magnetic resonance images (MRI) and SPECT scans. Significant negative correlations were found between interpersonal features of psychopathy (the old and especially the new Factor 1) and the frontal and temporal perfusion. The two most clearly associated ROIs were the head of the caudate nuclei and the hippocampi. These findings in a group of violent offenders living under the same conditions, which reduced the number of state-related confounders, add to the evidence indicating that aberrant frontotemporal activity may be a factor in violent behavior.

Tidskriftsartikel (refereegranskat)abstract
- The present study was designed to replicate previously reported findings of abnormal frontal and/or temporal cerebral blood flow in violent offenders and to control for the influence of major mental disorder (MMD), substance abuse, and current medication. HMPAO-SPECT-CBF and MRI scans from pretrial forensic psychiatric investigations of 21 subjects convicted of impulsive violent crimes were retrospectively re-evaluated. In 16/21 subjects, visual assessment of SPECT scans showed some hypoperfusion in the temporal and/or frontal lobes. MRI showed no corresponding structural damage. Quantified regional cerebral blood flow (rCBF) in defined regions of interest was compared between index cases and 11 healthy control subjects. Index subjects had significant reductions in the right angular gyrus and the right medial temporal gyrus, bilaterally in the hippocampus, and in the left white frontal matter, but they had significantly increased rCBF in the parietal association cortex bilaterally. The aberrations were as frequent and severe among the subjects without MMD, substance abuse, and current medication (n=7) as in the entire group of index subjects.

Tidskriftsartikel (refereegranskat)abstract
- Childhood conduct disorder (CD) and adult psychopathic traits according to the Psychopathy Checklist Revised (PCL-R) were the closest psychiatric covariates to repeated violent crimes and aggression among offenders under forensic psychiatric investigation in Sweden. As psychopathy is not included in the present psychiatric diagnostic systems, we compared total and factor PCL-R scores to Axis I disorders, including childhood-onset neuropsychiatric disorders, and to Axis II personality disorders, to establish the convergence of psychopathic traits with other psychiatric diagnoses, and to identify possible unique features. Psychopathic traits were positively correlated with bipolar mood disorder and negatively with unipolar depression. The total PCL-R scores as well as the Factor 2 (unemotionality) and Factor 3 (behavioral dyscontrol) scores were significantly correlated with attention-deficit/hyperactivity disorder, Asperger's syndrome/high-functioning autistic traits, CD, substance abuse, and the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Cluster B personality disorders. The interpersonal Factor 1 showed none of these correlations and may capture features that are specific to psychopathy, distinguishing core psychopathy from other diagnostic definitions.
