Um capítulo esquecido na história da psicologia? sexualidades desviantes, psicopatologia e normalidade / A forgotten chapter in the history of psychology? deviant sexualities, psychopathology, and normality / ¿Un capítulo olvidado en la historia de la psicología? sexualidades desviadas, psicopatología y normalidad

Este artigo tem como objetivo produzir uma análise histórica sobre as intersecções entre Psicologia e sexualidade desviantes da norma no Brasil, de fins do século XIX a meados da década de 1980. Esta temporalidade foi escolhida por abarcar o surgimento das pesquisas científicas sobre sexualidade e desvios sexuais, a consolidação dos estudos psicológicos sobre a temática e o processo mais recente de despatologização da homossexualidade. Em termos teóricos e metodológicos, foram adotados os pressupostos da História Social da Psicologia e da historiografia das homossexualidades no Brasil. Desse modo, buscou-se compreender como as ideias, concepções e práticas psicológicas foram mudando ao longo do tempo, em conexão com as transformações socioculturais e políticas que ocorreram durante o século XX. Para isto, foram utilizadas fontes primárias e secundárias de pesquisa com vistas à produção de interpretações sobre as conexões entre as ideias, os atores e os eventos narrados. Argumenta-se, ao longo do artigo, que as ideias e práticas psicológicas estão intrinsecamente conectadas aos contextos socioculturais e políticos de seu tempo, sendo os movimentos dinâmicos e os conflitos presentes nesses contextos fatores determinantes para a sua constituição.(AU)

This article aims to produce a historical analysis of the intersections between Psychology and sexualities that deviate from the norm in Brazil, from the late 19th century to the mid-1980s. This period was chosen because it encompasses the emergence of scientific research on sexuality and sexual deviations, the consolidation of psychological studies on the subject and the most recent process of de-pathologization of homosexuality. Theoretically and methodologically, the assumptions of the Social History of Psychology and the historiography of homosexualities in Brazil were adopted. Therefore, we sought to understand how psychological ideas, conceptions and practices have changed over time, in connection with the sociocultural and political transformations that occurred throughout the 20th century. For this, primary and secondary sources of research were used to produce interpretations about the connections between the ideas, the actors and the narrated events. It is argued, throughout the article, that the psychological ideas and practices are intrinsically connected to the sociocultural and political contexts of their time, being the dynamic movements and conflicts present in these contexts determining factors for their constitution.(AU)

Directional Deep Brain Stimulation of the Posteromedial Hypothalamus for Refractory Intermittent Explosive Disorder: A Case Series Using a Novel Neurostimulation Device and Intraoperative Microdialysis.

BACKGROUND: Intermittent explosive disorder (IED) is a psychiatric disorder characterized by recurrent outbursts of aggressive behavior. Deep brain stimulation (DBS) in the posteromedial nucleus of the hypothalamus (pHyp) is an alternative therapy for extreme cases and shows promising results. Intraoperative microdialysis can help elucidate the neurobiological mechanism of pHyp-DBS. We sought to evaluate efficacy and safety of pHyp-DBS using 8-contact directional leads in patients with refractory IED (rIED) and the accompanying changes in neurotransmitters. METHODS: This was a prospective study in which patients with a diagnosis of rIED were treated with pHyp-DBS for symptom alleviation. Bilateral pHyp-DBS was performed with 8-contact directional electrodes. Follow-up was performed at 3, 6, and 12 months after surgery. RESULTS: Four patients (3 men, mean age 27 ± 2.8 years) were included. All patients were diagnosed with rIED and severe intellectual disability. Two patients had congenital rubella, one had a co-diagnosis of infantile autism, and the fourth presented with drug-resistant epilepsy. There was a marked increase in the levels of gamma-aminobutyric acid and glycine during intraoperative stimulation. The average improvement in aggressive behavior in the last follow-up was 6 points (Δ: 50%, P = 0.003) while also documenting an important improvement of the Short Form Health Survey in all domains except bodily pain. No adverse events associated with pHyp-DBS were observed. CONCLUSIONS: This is the first study to show the safety and beneficial effect of directional lead pHyp-DBS in patients with rIED and to demonstrate the corresponding mechanism of action through increases in gamma-aminobutyric acid and glycine concentration in the pHyp.

Instantaneous Respiratory Response of Gamer with High-Risk Internet Gaming Disorder during Game-Film Stimuli by Using Complementary Ensemble Empirical Mode Decomposition.

Gamers with Internet gaming disorder (IGD) dynamically regulate their psychophysiological responses during playing; however, analyzing instantaneous psychophysiological responses in these gamers has been limited by a lack of appropriate methods. We propose combining the Complementary Ensemble Empirical Mode Decomposition and Direct Quadrature methods to overcome this limitation. The related effect of abdominal breathing (AB) training (as a relaxing psychology method) on the distribution of instantaneous frequency (IF) was investigated by calculating median (IFmed), kurtosis (IFkurt) and skewness (IFskew), and 19 participants with high-risk IGD (HIGD) were found to have increased IFmed [massively multiplayer online role-playing game (MMORPG): 0.36 ± 0.08; first-person shooter game (FPSG): 0.34 ± 0.08] but decreased IFkurt (MMORPG: 5.98 ± 2.31; FPSG: 6.84 ± 4.61) and IFskew (MMORPG: 0.40 ± 0.69; FPSG: 0.64 ±1.04) during game-film stimuli compared with baseline and recovery states. After AB training, IFmed of these 19 participants (MMORPG: 0.24 ± 0.11; FPSG: 0.18 ± 0.06) decreased significantly. This study is firstly to observe the IF distribution of respiratory signal in gamers with HIGD; thus, this distribution may be used as a respiratory physiological marker of IGD risk.

Group therapy for excoriation disorder: Psychodrama versus support therapy.

BACKGROUND: Excoriation disorder (ED) is characterized by recurring excoriation of the skin resulting in tissue damage, usually associated with emotional deregulation. Psychotherapy is a valuable treatment; however, no studies emphasize the patients' interactional aspect, nor the potential benefit of group treatment. METHODS: We recruited a convenience sample of 38 individuals with ED according to DSM-5 criteria, in which 19 individuals proceeded to treatment, 10 with psychodrama group therapy (PGT), and 9 with support group therapy (SGT) in an open pilot study. RESULTS: The entire sample presented improvement of skin excoriation on both self-report and clinician rating and improvement of social adjustment; however, there was no difference between groups (ie, time × group interaction). Also, there was no relevant change for anxiety, depression, or emotional regulation throughout treatment. Emotional deregulation was associated with excoriation severity as well as depression, anxiety, and social maladjustment, both at the beginning and end of treatment. CONCLUSIONS: Although both groups showed improvement of skin picking, the results contradict our primary hypothesis that PGT would have a superior efficacy to SGT for patients with ED. The findings encourage future studies of group interventions for ED in larger samples with a focus on emotional regulation enhancement.

The efficacy of biofeedback approaches for obsessive-compulsive and related disorders: A systematic review and meta-analysis.

Biofeedback is applied to target excessive and/or deficient physiological signals to help patients identifying and self-managing their symptoms. Biofeedback has been employed in psychiatric disorders, including obsessive-compulsive disorder (OCD), mainly by using neural signals - neurofeedback. Recently, OCD has been integrated into the obsessive-compulsive and related disorders (OCD&RD) category (body dysmorphic, hoarding, trichotillomania/hair-pulling, and excoriation/skin-picking disorders). The efficacy of biofeedback for OCD&RD is still unknown. Our work provides a complete overview of publications assessing the therapeutic efficacy of biofeedback in OCD&RD with a systematic review and meta-analysis. We found ten studies involving 102 OCD participants (three randomized controlled trials) mostly applying neurofeedback (one publication used thermal biofeedback). Five neurofeedback studies were selected for meta-analysis (89 patients; two randomized controlled trials). The overall effect size within the treatment group varied between medium to large, but high heterogeneity and inconsistency values were found. The methodological quality was low indicating a high risk of bias. In conclusion, a beneficial effect of neurofeedback for OCD patients was found but also critical limitations on methodology, high heterogeneity among studies, and a putative reporting bias. Future research following high-quality guidelines should be conducted to address the efficacy of biofeedback approaches for OCD&RD.

Electro-acupuncture treatment for internet addiction: Evidence of normalization of impulse control disorder in adolescents.

OBJECTIVE: To observe the impacts of electro-acupuncture (EA) and psychological intervention (PI) on impulsive behavior among internet addiction (IA) adolescents. METHODS: Thirty-two IA adolescents were allocated to either EA (16 cases) or PI (16 cases) group by a randomized digital table. Subjects in the EA group received EA treatment and subjects in the PI group received cognition and behavior therapy. All adolescents underwent 45-d intervention. Sixteen healthy volunteers were recruited into a control group. Barratt Impulsiveness Scale (BIS-11) scores, Young's Internet Addiction Test (IAT) as well as the ratio of brain N-acetyl aspartate (NAA) to creatine (NAA/Cr) and choline (Cho) to creatine (Cho/Cr) were recorded by magnetic resonance spectroscopy before and after intervention respectively. RESULTS: The IAT scores and BIS-11 total scores in both EA and PI group were remarkably decreased after treatment (P<0.05), while EA group showed more significant decrease in certain BIS-11 sub-factors (P<0.05). Both NAA/Cr and Cho/Cr were significantly improved in EA group after treatment (P<0.05); however, there were no significant changes of NAA/Cr or Cho/Cr in PI group after treatment (P>0.05). CONCLUSIONS: Both EA and PI had significantly positive effect on IA adolescents, especially in the aspects of psychological experiences and behavioral expressions, EA might have an advantage over PI in terms of impulsivity control and brain neuron protection. The mechanism underlying this advantage might be related to the increased NAA and Cho levels in prefrontal and anterior cingulate cortices.

Alternative Therapies for Excoriation (Skin Picking) Disorder: A Brief Update.

Context • Excoriation (skin picking) disorder is characterized by the need or urge to pick, scratch, pinch, touch, rub, scrub, squeeze, bite, or dig the skin, and it can be a perplexing condition for the inexperienced physician. Treatments include pharmacotherapy, psychotherapy, and alternative therapies. Alternative therapies for excoriation disorder and other body-focused repetitive behaviors include yoga, aerobic exercise, acupuncture, biofeedback, hypnosis, and inositol and N-acetylcysteine, among others. Objective • This review article intended to review the current literature on the alternative therapies to provide a brief update on their benefits for the treatment of excoriation disorder for use in conjunction with psychotherapy and pharmacotherapy in the management of a challenging group of patients. Design • This review (focusing on literature published in the last 15 y, selected from a search of PubMed) critically considers the evidence for the use of alternative therapies in the treatment of excoriation disorder. Setting • This review was conducted at the National University of Asunción (San Lorenzo, Paraguay). Results • Results for yoga were as follows: This technique may influence the structure and functioning of the areas of emotional processing involved in the pathophysiology of excoriation disorder and other body-focused repetitive behaviors, such as trichotillomania. Although still limited, the current research team's use of yoga as a treatment has given useful results. Results for aerobic exercise were as follows: People suffering from excoriation disorder and other-body focused repetitive behaviors generally have a worsening of their behaviors in times of negative mood and anxiety. As exercise has qualities that allow individuals to improve their mood and reduce their anxiety, it is likely that it also can help reduce behaviors like hair pulling or scratching, and it should be considered to be an adjunctive therapy. Results for acupuncture were as follows: The mechanism of action of acupuncture increases serotonergic activity and releases endorphins in the hypothalamus and limbic region, which could be beneficial in patients with trichotillomania and excoriation disorder. Results for biofeedback were as follows: Several case reports have suggested the value of biofeedback in reducing tics, which bear some psychophysiological similarities to body-focused repetitive behaviors, such as trichotillomania and excoriation disorder. Results for hypnosis were as follows: When used as a channel for other types of interventions, such as psychotherapy, hypnosis can help counteract the stress that triggers the picking behaviors in some patients. Results for inositol and N-acetylcysteine were as follows: Although more research is needed, these are promising drugs that may be helpful in reducing the picking behavior. Conclusions • The review indicates that yoga, aerobic exercise, acupuncture, biofeedback, hypnosis, and inositol and N-acetylcysteine all show promise in the treatment of excoriation disorder and other body-focused repetitive behaviors, such as trichotillomania. In the current research team's experience, mainly yoga and aerobic exercise have been shown useful in combination with psychotherapy and pharmacotherapy. Obtaining solid evidence about the long-term beneficial effects of these alternative therapies for the treatment of excoriation disorder requires more investigation.

Religiosity is a moderator of the relationship between impulsivity and internalizing symptoms

Abstract Background There is growing interest in the role of religion in psychiatric disorders. Impulsivity is a psychological trait associated with acting without thinking, with a decision process favoring short-term outcomes without further consideration of its consequences, and is a risk factor for the development of mental disorders. Objective In this study, the objective was to analyze the role of religiosity as a possible moderator between the association of impulsivity and internalizing psychiatric symptoms. Methods The hypothesis was assessed in a cross-sectional study enrolling 366 adults evaluated using the abbreviated version of the Barratt Impulsiveness Scale-11, the Self Reporting Questionnaire-20, and the Duke Religion Index. Results Internalizing symptoms were significantly influenced by an interaction between religiosity and impulsivity. Religiosity acted as a protective factor against internalizing symptoms only for participants with high impulsivity. Discussion The results suggest a moderation role of religiosity in the association of impulsivity with internalizing symptoms.

Mindfulness and Rehabilitation: Teaching Yoga and Meditation to Young Men in an Alternative to Incarceration Program.

This study used participant/observation and open-ended interviews to understand how male participants (age 18-24 years) benefited from yoga and mindfulness training within an Alternative to Incarceration (ATI) program. Findings suggest that the male participants (age 18-24 years) benefited from the intervention through reductions in stress and improvements in emotion regulation. Several participants noted the importance of the development of an embodied practice for assisting them in managing anger and impulse control. The young men's narratives suggest that mindfulness-based interventions can contribute positively to rehabilitative outcomes within alternative to incarcerations settings, providing complementary benefit to existing ATI programs, especially for clients amenable to mindfulness training. With many jurisdictions expanding rehabilitation-focused interventions for young offenders, service providers should consider the potential positive contributions that mindfulness-based interventions can have for fostering desistance and reducing recidivism among justice system-involved populations.

Neural Correlates and Connectivity Underlying Stress-Related Impulse Control Difficulties in Alcoholism.

BACKGROUND: Stress triggers impulsive and addictive behaviors, and alcoholism has been frequently associated with increased stress sensitivity and impulse control problems. However, neural correlates underlying the link between alcoholism and impulsivity in the context of stress in patients with alcohol use disorders (AUD) have not been well studied. METHODS: This study investigated neural correlates and connectivity patterns associated with impulse control difficulties in abstinent AUD patients. Using functional magnetic resonance imaging, brain responses of 37 AUD inpatients, and 37 demographically matched healthy controls were examined during brief individualized imagery trials of stress, alcohol cue, and neutral-relaxing conditions. Stress-related impulsivity was measured using a subscale score of impulse control problems from Difficulties in Emotion Regulation Scale. RESULTS: Impulse control difficulties in AUD patients were significantly associated with hypo-active response to stress in the ventromedial prefrontal cortex (VmPFC), right caudate, and left lateral PFC (LPFC) compared to the neutral condition (p < 0.01, whole-brain corrected). These regions were used as seed regions to further examine the connectivity patterns with other brain regions. With the VmPFC seed, AUD patients showed reduced connectivity with the anterior cingulate cortex compared to controls, which are core regions of emotion regulation, suggesting AUD patients' decreased ability to modulate emotional response under distressed state. With the right caudate seed, patients showed increased connectivity with the right motor cortex, suggesting increased tendency toward habitually driven behaviors. With the left LPFC seed, decreased connectivity with the dorsomedial PFC (DmPFC), but increased connectivity with sensory and motor cortices were found in AUD patients compared to controls (p < 0.05, whole-brain corrected). Reduced connectivity between the left LPFC and DmPFC was further associated with increased stress-induced anxiety in AUD patients (p < 0.05, with adjusted Bonferroni correction). CONCLUSIONS: Hypo-active response to stress and altered connectivity in key emotion regulatory regions may account for greater stress-related impulse control problems in alcoholism.

Tricotilomanía: tratamiento psicodinámico de un caso / Trichotillomania: a case study in psychodynamic treatment / Tricotil·lomania: tractament psicodinàmic d’un cas

Se presenta la psicopatología de la tricotilomanía y otras conductas repetitivas centradas en el cuerpo, así como las claves de su tratamiento a través de la psicoterapia psicoanalítica breve aplicada a un caso. Se obtienen varias conclusiones: la paciente tricotilomaníaca, a pesar de aparentar baja mentalización, muestra una actividad imaginaria que permite el acceso al análisis de sus sueños; la fijación a un conflicto oral reprimido, que atañe al proceso arcaico de separación, formación del yo y diferenciación psique/soma, es el núcleo principal del trastorno; para el acceso y elaboración de los contenidos inconscientes es importante un trabajo terapéutico sobre la diada madre-hija (AU)

The psychopathology of trichotillomania and other repetitive behaviors focused on the body is presented. We describe the keys to their treatment, through a brief process of psychoanalytic psychotherapy applied to a case. Several conclusions are reached: the trichotillomaniac patient, despite appearing to have a low degree of mentalization, displays imaginary activity that allows for access to the analysis of his or her dreams; the fixation on a repressed oral conflict, associated with the archaic process of separation (on formation of the Ego and of the psyche / soma differentiation), is the core of this disorder; in order to help the patient access and process unconscious contents, it is important to undertake therapeutic work on the mother-daughter dyad (AU)

S’obtenen diverses conclusions: la pacient tricotil·lomaníaca, tot i aparentar baixa mentalització, mostra una activitat imaginària que permet l’accés a l’anàlisi dels seus somnis; la fixació a un conflicte oral reprimit, que pertoca al procés arcaic de separació, formació del jo i diferenciació psique/soma, és el nucli principal del trastorn; per l’accés i l’elaboració dels continguts inconscients, és important un treball terapèutic sobre la díada mare-filla

Transtorno explosivo intermitente: relato de caso com tratamento homeopático

Introdução: A homeopatia foi desenvolvida por Cristiano Frederico Samuel Hahnemann, médico alemão, vivido entre 1755 e 1843. Tem como objetivo avaliar de forma individualizada e integral o paciente, a fim de encontrar o melhor remédio homeopático que se assemelhe ao quadro do enfermo, partindo do princípio de que o “semelhante cura o semelhante”. A homeopatia se mostra como grande aliada nos tratamentos de saúde mental, uma vez que tem diversas opções de medicamentos, indicados de forma individualizada aos enfermos. Diante da crescente prevalência de transtornos de saúde mental na população mundial, nos deparamos com poucas opções de tratamentos alopáticos para tantas enfermidades distintas. Objetivo: Relatar um caso de tratamento homeopático em um paciente da Estratégia da Saúde da Família com quadro crônico de Transtorno Explosivo Intermitente. Metodologia: Estudo realizado a partir de um relato de caso atendido com homeopatia, medicamento nux vômica, em um quadro crônico de Transtorno Explosivo Intermitente. Realizada ainda revisão bibliográfica sobre o tema e correlação com a homeopatia. Resultado: O tratamento homeopático do caso relatado mostrou-se eficiente tanto para a abordagem mental, quanto para a síndrome dispéptica. Considerações finais: A homeopatia se mostra como grande aliada nos tratamentos de saúde mental, uma vez que tem diversas opções de medicamentos, indicados de forma individualizada aos enfermos. (AU)

Introduction: Homeopathy was developed by Christian Frederik Samuel Hahnemann, a German physician, lived between 1755 and 1843. It aims to evaluate individually and holistically the patient in order to find the best homeopathic remedy that resembles the patient's chart, assuming that "like cures like." Homeopathy shows to be a great ally in mental health treatment, since it has several options of medications indicated individually to the patient. Given the increasing prevalence of mental health disorders in the world population, we are faced with few options for allopathic treatments for many different diseases. Objective: To report a homeopathic treatment in case of a patient of the Family Health Strategy with a chronic condition of Intermittent Explosive Disorder. Methodology: A study carried out from a case report treated with homeopathy, medicine nux vômica, in a chronic condition of Intermittent Explosive Disorder. Still performed a literature review on the subject and correlation with homeopathy. Result: Homeopathic treatment of this case proved to be efficient for both the mental approach and the dyspeptic syndrome. Final Thoughts: Homeopathy shows to be a great ally in mental health treatment, since it has several options of medications indicated individually to the patient. (AU)

Apathy and Impulse Control Disorders: Yin & Yang of Dopamine Dependent Behaviors.

Neuropsychiatric symptoms are common non-motor symptoms in Parkinson's disease (PD). Apathy and impulse control disorders (ICD) are two opposite motivational expressions of a continuous behavioural spectrum involving hypo- and hyperdopaminergia. Both syndromes share pathological (decreased vs increased) dopamine receptor stimulation states. Apathy belongs to the spectrum of hypodopaminergic symptoms together with anhedonia, anxiety and depression. Apathy is a key symptom of PD which worsens with disease progression. Animal models, imaging and pharmacological studies concur in pointing out dopaminergic denervation in the aetiology of parkinsonian apathy with a cardinal role of decreased tonic D2/D3 receptor stimulation. ICDs are part of the hyperdopaminergic behavioural spectrum, which also includes punding, and dopamine dysregulation syndrome (DDS), which are all related to non-physiological dopaminergic stimulation induced by antiparkinsonian drugs. According to clinical data tonic D2/D3 receptor stimulation can be sufficient to induce ICDs. Clinical observations in drug addiction and PD as well as data from studies in dopamine depleted rodents provide hints allowing to argue that both pulsatile D1 and D2 receptor stimulation and the severity of dopaminergic denervation are risk factors to develop punding behavior and DDS. Imaging studies have shown that the brain structures involved in drug addiction are also involved in hyperdopaminergic behaviours with increase of bottom-up appetitive drive and decrease in prefrontal top down behavioural control.

Propiedades psicométricas de la versión española de la "Escala de atención y conciencia plena para adolescentes" (Mindful Attention Awareness Scale-Adolescents) (MAAS-A) / Psychometric properties of the Spanish version of the Mindful Attention Awareness Scale-Adolescents (MAAS-A)

El rasgo de conciencia plena ha recibido considerable atención debido a que numerosos estudios muestran que el entrenamiento en conciencia plena reduce los síntomas de numerosos problemas psicológicos, como la depresión. Recientemente el entrenamiento en meditación se ha extendido a adolescentes. Por ello la medición del rasgo de conciencia plena en adolescentes es importante. Este estudio evalúa las propiedades de la "Escala de atención y conciencia plena para adolescentes" (MAAS-A) en españoles. Participaron 1215 adolescentes (597 chicas y 618 chicos) entre 14 y 18 años, quienes completaron la MAAS-A junto con medidas de depresión, conducta antisocial, ira, consumo de alcohol y drogas y autocontrol. Los resultados confirman la estructura unidimensional de la MAASA y muestran correlaciones negativas significativas entre conciencia plena y los síntomas de depresión, la conducta antisocial, la ira, el consumo de drogas y el bajo autocontrol. Además, los adolescentes con síntomas de estado de ánimo depresivo grave puntúan significativamente más bajo en el rasgo de conciencia plena que los adolescentes sin síntomas, con síntomas ligeros y con síntomas oderados de depresión

Trait mindfulness has received considerable attention in recent years because several studies indicate that the training in mindfulness reduces the symptoms of several psychological problems such as depression. Recently, the training in mindfulness has been extended to samples of adolescents. Therefore, the measurement of trait mindfulness in adolescents has become relevant. In this study the psychometric properties of the Mindful Attention Awareness Scale- Adolescents (MAAS-A) are evaluated in Spanish adolescents. For this purpose, 1215 adolescents (597 girls and 618 boys) aged between 14 and 18 years old participated in this study. The adolescents completed the MAAS-A and measures of depression, antisocial behavior, anger, drug abuse and lack of self-control. The results confirm the one-factor structure of the MAAS-A. The trait of mindfulness is negatively correlated with symptoms of depression, antisocial behavior, anger, drug abuse and lack of self-control. Furthermore, the adolescents who display severe depressed mood score significantly lower on mindfulness than the adolescents without symptoms or with mild and moderate depressive mood

Effects of mindful eating training on delay and probability discounting for food and money in obese and healthy-weight individuals.

Obese individuals tend to behave more impulsively than healthy weight individuals across a variety of measures, but it is unclear whether this pattern can be altered. The present study examined the effects of a mindful eating behavioral strategy on impulsive and risky choice patterns for hypothetical food and money. In Experiment 1, 304 participants completed computerized delay and probability discounting tasks for food-related and monetary outcomes. High percent body fat (PBF) predicted more impulsive choice for food, but not small-value money, replicating previous work. In Experiment 2, 102 randomly selected participants from Experiment 1 were assigned to participate in a 50-min workshop on mindful eating or to watch an educational video. They then completed the discounting tasks again. Participants who completed the mindful eating session showed more self-controlled and less risk-averse discounting patterns for food compared to baseline; those in the control condition discounted similarly to baseline rates. There were no changes in discounting for money for either group, suggesting stimulus specificity for food for the mindful eating condition.

Hippocampal agenesis in an individual who engaged in violent criminal behaviors after discontinuing carbamazepine and paroxetine treatment.

Antidepressant discontinuation syndrome (ADS) occurs after abrupt discontinuation of an antidepressant medication. A 23-year-old man with right hippocampal agenesis demonstrated sexual crime (hypersexuality) since the age of eight and had been successfully treated with carbamazepine since the age of 13. He had required increased doses of paroxetine and carbamazepine owing to the development of an unstable affect after quitting his job. He abruptly stopped taking his medication for 3 days and his criminal behaviors re-emerged. We examined changes in brain structure and activity before and after medication cessation, using MRI and functional MRI (fMRI). The image of a girl in a swimsuit increased activity in the thalamus only after medication discontinuation. The alteration in thalamic activity might induce hypersexuality. We conclude that a primary hypersexuality had been suppressed with carbamazepine and paroxetine treatment, and the discontinuation of the medication caused the hypersexuality.

Impulse control disorders in Parkinson's disease.

Impulse control disorders (ICDs), a group of complex behavioral disorders, occur more commonly in Parkinson's disease (PD) patients than in the general population, with a reported prevalence up to 13.6% in some studies. The most common ICDs reported are pathological gambling (PG), hypersexuality (HS), compulsive shopping and compulsive eating. More than a quarter of the patients with ICDs have 2 or more behavioral addictions. These abnormal behaviors impair activities of daily living and have a negative impact on quality of life of patients and their families. As with many other non motor symptoms in PD, ICDs are frequently under-reported by patients and caregivers and may be under-recognized by the treating physicians. Treatment with dopamine agonists (DA) is the main risk factor for developing ICDs, and stimulation of mesolimbic D3 receptors by DA is thought to underlie their development. The DA effect seems to be a class effect and not specific for any DA. Levodopa can also induce ICDs but much less so than the DAs. The management of ICDs in PD is complex. Modifications in dopaminergic drug treatment are frequently necessary. In some cases alternative therapies such as atypical antipsychotics, antidepressants or deep brain stimulation if motor symptoms become incapacitating after adjustment of dopamine replacement therapy should be considered.

A randomized controlled trial of a novel self-help technique for impulse control disorders: a study on nail-biting.

Nail-biting is currently classified as an impulse control disorder not otherwise specified. Although seldom targeted as a primary symptom, nail-biting is often associated with somatic complications and decreased quality of life. The present study assessed the effectiveness of an innovative self-help technique, titled decoupling (DC). DC aims at attenuating pathological nail-biting by performing motor sequences that decouple and rearrange the behavioral elements involved in the habit. A total of 72 participants with excessive nail-biting were recruited via specialized self-help forums and were randomized to either DC or progressive muscle relaxation (PMR) groups after baseline assessment. Four weeks later, participants underwent a similar assessment as before and were asked to rate the effectiveness of the intervention. The primary outcome parameter was the Massachusetts General Hospital Scale (MGH) adapted. Relative to the PMR group, the DC group showed significant progress in withstanding the urge to bite their nails. Furthermore, they appraised the appearance of their nails as considerably less compromised at the end of the treatment relative to participants undergoing PMR. At statistical trend level, the DC group showed a significantly greater decline on the adapted MGH relative to PMR. Despite methodological limitations, the present study asserts that the effectiveness of DC, previously shown for trichotillomania, extends to nail-biting.

Deep brain stimulation of the orbitofrontal projections for the treatment of intermittent explosive disorder.

Intermittent explosive disorder (IED) is characterized by a dysfunction in the greater limbic system leading an individual to experience sudden aggressive behavior with little or no environmental perturbation. This report describes a procedure for the treatment of IED in a 19-year-old woman with a history of IED, having had episodes of severe violent attacks against family, dating to early childhood. Due to the severity and intractability of the illness, deep brain stimulation was performed, targeting the orbitofrontal projections to the hypothalamus. The patient's history and the procedure, management, and rationale are described in detail.
