The Addictive Potential of Sexual Behavior (Impulse) Review2 Page 1 of 9 Impulse: The Premier Journal for Undergraduate Publications in the Neurosciences Submitted for Publication January, 2018 The Addictive Potential of Sexual Behavior Heather Bool D’Youville College, Buffalo, New York This paper examines the addictive potential of sexual behavior through behavioral and neurophysiological mechanisms analogous to other formalized addictions. Sexual behavior refers to any action or thought preformed with the intention of sexual gratification, such as the consumption of explicit material, masturbation, fantasizing of sexual scenarios, and sexual intercourse. Addiction is defined by the presence of tolerance, preoccupation, withdrawal, dependence, and the continuation of behavior despite risk and/or harm. Sexual addiction demonstrates high relapse potential due to the frequency of reward-associated cues encountered in daily life, and the low effort and risk required for sexual pleasure. Currently, sexual addiction lacks a formal diagnosis despite behavioral, psychological, and physiological evidence. An official diagnosis recognized by a governing authority, such as the American Psychological Association, would offer greater access to treatment, funding for research, and exposure and education for the general public about this disorder.

  • Amphetamine Sensitization Alters Hippocampal Neuronal Morphology and Memory and Learning Behaviors
    Molecular Psychiatry https://doi.org/10.1038/s41380-020-0809-2 ARTICLE Amphetamine sensitization alters hippocampal neuronal morphology and memory and learning behaviors 1,2,5 1,2 1 Luis Enrique Arroyo-García ● Hiram Tendilla-Beltrán ● Rubén Antonio Vázquez-Roque ● 1 3 3 3 1 Erick Ernesto Jurado-Tapia ● Alfonso Díaz ● Patricia Aguilar-Alonso ● Eduardo Brambila ● Eduardo Monjaraz ● 2 4 1 Fidel De La Cruz ● Antonio Rodríguez-Moreno ● Gonzalo Flores Received: 12 November 2019 / Revised: 29 May 2020 / Accepted: 3 June 2020 © The Author(s), under exclusive licence to Springer Nature Limited 2020 Abstract It is known that continuous abuse of amphetamine (AMPH) results in alterations in neuronal structure and cognitive behaviors related to the reward system. However, the impact of AMPH abuse on the hippocampus remains unknown. The aim of this study was to determine the damage caused by AMPH in the hippocampus in an addiction model. We reproduced the AMPH sensitization model proposed by Robinson et al. in 1997 and performed the novel object recognition test (NORt) to evaluate learning and memory behaviors. After the NORt, we performed Golgi–Cox staining, a 1234567890();,: 1234567890();,: stereological cell count, immunohistochemistry to determine the presence of GFAP, CASP3, and MT-III, and evaluated oxidative stress in the hippocampus. We found that AMPH treatment generates impairment in short- and long-term memories and a decrease in neuronal density in the CA1 region of the hippocampus. The morphological test showed an increase in the total dendritic length, but a decrease in the number of mature spines in the CA1 region. GFAP labeling increased in the CA1 region and MT-III increased in the CA1 and CA3 regions.

L. de Zwart1*, B. F.

For the past quarter of a century, Frank et al.’s (1991) consensus-based definitions of major depressive disorder (MDD) episode, remission, recovery, relapse and recurrence have been the paramount driving forces for consistency in MDD research as well as in clinical practice. This study aims to review the evidence for the empirical validation of Frank et al.’s proposed concept definitions and to discuss evidence-based modifications. Methods. A literature search of Web of Science and PubMed from 1/1/1991 to 08/30/2017 identified all publications which referenced Frank et al.’s request for definition validation. Publications with data relevant for validation were included and checked for referencing other studies providing such data. Results. A total of 56 studies involving 39 315 subjects were included, mainly presenting data to validate the severity and duration thresholds for defining remission and recovery. Most studies indicated that the severity threshold for defining remission should decrease. Additionally, specific duration thresholds to separate remission from recovery did not add any predictive value to the notion that increased remission duration alleviates the risk of reoccurrence of depressive symp- toms.

DEBORAH CORLEY Sante´ Center for Healing, Argyle, Texas SARA E. POLLARD and JOSHUA N. HOOK University of North Texas, Denton, Texas JENNIFER P. SCHNEIDER Tucson, Arizona Disclosure as a process of both recovery and healing within commit- ted relationships is advocated by couple and addiction therapists. The traumatic impact for partners of an initial disclosure or discov- ery of betrayals has been well documented, but less is known about the impact of disclosure for sex addicts. The present study explored the experience of relapse and disclosure among sex addicts. Relapse was a common experience among sex addicts, and the disclosure of relapse had a range of consequences for the addict and the re- lationship. Voluntary disclosure of relapse (rather than the partner discovering relapses independently) was associated with positive relational outcomes. The majority of sexual behaviors engaged in by sexual addicts who are in a committed relationship are considered a violation of trust by their partners (Bird, Butler, & Fife, 2007; Kalichman & Cain, 2004; Young, Griffin-Shelley, Cooper, O’Mara, & Buchanan, 2000). This violation is also considered a betrayal and may be described as a secret sexual, romantic, or emotional involvement that violates the rules of and commitment to an exclusive re- lationship (Glass, 2002; Laaser, 2011; Whisman & Wagers, 2005). The most significant betrayals are those associated with repeated secrets, lies, decep- tions, and broken promises (Corley & Schneider, 2002; Corley, Schneider, Thanks to Dr.

Eran Shor and Kimberly Seida Department of Sociology, McGill University, Montreal, Quebec, Canada It is a common notion among many scholars and pundits that the pornography industry becomes “harder and harder” with every passing year. Some have suggested that porn viewers, who are mostly men, become desensitized to “soft” pornography, and producers are happy to generate videos that are more hard core, resulting in a growing demand for and supply of violent and degrading acts against women in mainstream pornographic videos. We examined this accepted wisdom by utilizing a sample of 269 popular videos uploaded to PornHub over the past decade.

The psychostimulant MPH is therapeutically used in the treatment of ADHD, but has been implicated in many pharmacological actions related to drug addiction and is considered to have abuse potential. Past work in our lab and others have shown substantial sex-differences in the neuropharmacological profile of MPH. Here a discussion of the relevant mechanisms of action of MPH and its relationship to neurotrophins and CPP are reviewed.

  • Use of DSM Paraphilia Diagnoses in Sexually Violent Predator Commitment Cases
    SPECIAL ARTICLE Use of DSM Paraphilia Diagnoses in Sexually Violent Predator Commitment Cases Michael B. First, MD, and Robert L. Halon, PhD There is legitimate concern in the psychiatric community about the constitutionality of sexually violent predator (SVP) commitment statutes. Such constitutionality depends on the requirement that a sexual offender have a mental abnormality that makes him commit violent predatory sex offenses and reflects almost exclusively a concern for public safety, with little regard for notions of clinical sensibility or diagnostic accuracy. However, given that mental health experts’ diagnostic opinions are, and will continue to be, important to the triers of fact in regard to the application of the SVP statutes, we describe valid means of making a DSM-IV-TR paraphilic diagnosis. We also provide a three-step approach for the judicious application of the diagnosis in the context of SVP commitment evaluations that emphasizes the importance of not making a paraphilia diagnosis based solely on the sexual offenses themselves. Finally, we discuss the appropriate use of a paraphilia NOS diagnosis in SVP cases. J Am Acad Psychiatry Law 36:443–54, 2008 In 1990, the state of Washington passed the first Despite several challenges to the constitutionality sexually violent predator (SVP) involuntary commit- of SVP statutes, the U.S. Supreme Court in two sep- ment statute, which was designed to allow for the arate rulings (Kansas v.
