The Effects of Acute Transcranial Direct Current Stimulation on Attentional Bias in Pedophilic Disorder: A Preregistered Pilot Study.

Objectives: Individuals with pedophilic disorder (PD) experience personal and interpersonal difficulties and are at risk of sexually offending against children. As such, innovative and empirically validated treatments are needed. Recent studies have indicated that men who have sexually offended against children (SOC) with PD display an automatic attention bias for child-related stimuli as well as reduced activity in the dorsolateral prefrontal cortex (dlPFC), a brain area involved in cognitive control, including control over sexual arousal.

Measuring Pedophilic Sexual Interest.

Introduction: Pedophilic sexual interest is an important risk factor in sexual offender recidivism and remains a key component in the clinical assessment of child sexual offenders and people diagnosed with pedophilia. Despite concerns about the absence of universally accepted standardized clinical assessment methods, there are a number of established techniques aimed at assessing people with sexual interest in children.

Aim: To provide a foundation from which to understand existing methods available for the assessment of people with pedophilic sexual interests, including strengths and limitations of each approach.

Pedophilic brain potential responses to adult erotic stimuli.

Cognitive mechanisms associated with the relative lack of sexual interest in adults by pedophiles are poorly understood and may benefit from investigations examining how the brain processes adult erotic stimuli. The current study used event-related brain potentials (ERP) to investigate the time course of the explicit processing of erotic, emotional, and neutral pictures in 22 pedophilic patients and 22 healthy controls. Consistent with previous studies, early latency anterior ERP components were highly selective for erotic pictures.

Commentary: Zoophilia and the law.

We support the observation of Holoyda and Newman that common definitions of zoophilia are confusing and that legal definitions of bestiality and sentencing implications are inconsistent. We take issue with their contention that the finding of a history of sex with animals may be a significant risk factor for future harm to humans. We oppose their recommendation for new laws against bestiality to improve psychiatric knowledge about zoophilia.

Persons with intellectual disabilities and problematic sexual behaviors.

Persons with intellectual disabilities who have been identified because they committed a sexual offense may have done so because of a sexual paraphilia. However, special consideration in assessment is required to determine whether the offense is caused by a paraphilia alone or whether other factors relating to the individual's intellectual disabilities may be especially significant. This article reviews some factors that have been identified as significant and provides an overview of treatment approaches from multiple perspectives.

Can sexual offenders be treated?

There are many misconceptions about sexual offender treatment. This is not only a problem in the lay press and media but is also a problem amongst mental health professionals. In part, this relates to the inadequate teaching about sexual deviation in medical schools and psychiatric residency programs and even in forensic psychiatric fellowships.

The role of central and peripheral hormones in sexual and violent recidivism in sex offenders.

Hormonal factors are important in multifactorial theories of sexual offending. The relationship between hormones and aggression in nonhumans is well established, but the putative effect in humans is more complex, and the direction of the effect is usually unclear. In this study, a large sample (N = 771) of adult male sex offenders was assessed between 1982 and 1996.

A pilot study of electrocortical activity in dysfunctional anger: decreased frontocortical activation, impaired attention control, and diminished behavioral inhibition.

Dysfunctional anger, though not a primary clinical diagnosis per se, does present clinically as a pathological mood for which treatment is sought. Few studies have probed the neurocortical correlates of dysfunctional anger or assessed if cognitive processes, such as attention, are altered in dysfunctional anger. Though dysfunctional and high trait anger appears to be associated with biased processing of anger-eliciting information, few studies have examined if dysfunctional anger modulates attention more generally.

Resting electrocortical activity in adults with dysfunctional anger: a pilot study.

Although dysfunctional anger is not a DMS diagnosis, some individuals present with dysfunctional anger, to the exclusion of other psychiatric disorders, as the primary clinical feature. However, our understanding of the neural basis of dysfunctional anger is limited. Though previous work has examined electroencephalographic (EEG) activity in individuals with high trait anger, and in youth with disorders consistent with dysfunctional anger, no studies have assessed EEG activity in adults with dysfunctional anger.

Sexual affordances, perceptual-motor invariance extraction and intentional nonlinear dynamics: sexually deviant and non-deviant patterns in male subjects.

Sexual arousal and gaze behavior dynamics are used to characterize deviant sexual interests in male subjects. Pedophile patients and non-deviant subjects are immersed with virtual characters depicting relevant sexual features. Gaze behavior dynamics as indexed from correlation dimensions (D2) appears to be fractal in nature and significantly different from colored noise (surrogate data tests and recurrence plot analyses were performed).

Diagnostic values of polysomnography in forensic medicine.

A man accused of a first-degree murder of a two-year-old girl claimed that he had not been conscious during the time of the alleged murder. The possibility that he may have committed the crime while "sleepwalking" was raised. The forensic psychiatrist looked to the sleep disorders facility to conduct polysomnographic investigation of the accused in order to investigate the possibility that he had a parasomnia.

Manic-depressive and pure manic states after brain lesions.

Although mania is a rare complication of brain lesions, recent reports have emphasized the importance of lesion location and genetic predisposition in these patients. In the present study we compared patients who developed a bipolar affective disorder (i.e.

Anosognosia and major depression in 2 patients with cerebrovascular lesions.

We report 2 patients who developed a neglect syndrome, anosognosia, and major depression immediately after a right hemisphere cerebrovascular lesion. These cases demonstrate that neglect, anosognosia, and major depression may coexist in the same patient, and that the presence of anosognosia does not preclude the patient's recognition of emotional impairment.

Mania after brain injury: neuroradiological and metabolic findings.

We present a consecutive series of 8 patients who developed a manic episode after a brain injury. Five patients had cortical lesions (4 with damage to the right basotemporal region, and 1 with bilateral damage to the orbitofrontal area). While the other 3 patients had subcortical lesions (white matter of the right frontal lobe, right anterior limb of the internal capsule, and right head of the caudate), a fluorodeoxyglucose positron emission tomography scan showed hypometabolism in the right lateral basotemporal region in all 3 patients.

Relationship between anxiety disorders and depressive disorders in patients with cerebrovascular injury.

The interaction between anxiety disorder and major depressive disorder in patients with cerebrovascular lesions was examined in a controlled, 2 x 2 study design. A consecutive series of 24 patients who met criteria for major depression only were compared with 6 patients who met criteria for both major depression and generalized anxiety disorder, and 45 patients who did not meet criteria for either major depression of generalized anxiety. Among patients with positive computed tomographic scans, the anxious-depressed group (n = 19) showed a significantly higher frequency of cortical lesions, while patients with major depression only (n = 15) had a significantly higher frequency of subcortical (basal ganglia) strokes.
