Current Understanding of Compulsive Sexual Behavior Disorder and Co-occurring Conditions: What Clinicians Should Know about Pharmacological Options.

Compulsive sexual behavior disorder (CSBD) has recently been recognized as a psychiatric disorder. Pharmacological treatments for CSBD have received little study and thus have limited empirical support. The main objective of the present work is to review existing literature on the efficacy of different drugs on the symptomatology of CSBD, including the subtype of problematic pornography use (PPU). The main pharmacological approaches to treating CSBD have included opioid antagonists (naltrexone and nalmefene), selective serotonin reuptake inhibitors (paroxetine, citalopram, fluoxetine, and sertraline), mood stabilizers (topiramate), tricyclic antidepressants (clomipramine), serotonin antagonist and reuptake inhibitors (nefazodone), and N-acetylcysteine. Since people with CSBD may experience different co-occurring disorders, these should be considered when choosing the best pharmacological treatment. Pharmacological therapy for CSBD/PPU has been suggested as an adjunct to psychological therapies, which, for the moment, have the most empirical evidence. However, to evaluate the efficacy of most of the drugs presented in this narrative review, data to date have only been available from case studies. Thus, empirical support is scant and generalizability of results is limited, highlighting the need for more research in this area.

The prevalence of impulsive compulsive behaviors in patients treated with apomorphine infusion: a retrospective analysis / Prevalência de comportamentos impulsivo-compulsivos em pacientes tratados com infusão de apomorfina: análise retrospectiva

ABSTRACT Background: Impulsive compulsive behaviors (ICBs) can affect a significant number of Parkinson's disease (PD) patients. Objective: We have studied brain samples from a brain bank of PD patients who received apomorphine via continuous infusion in life to assess the prevalence and outcome of ICBs. Methods: A search on the Queen Square Brain Bank (QSBB) database for cases donated from 2005 to 2016 with a pathological diagnosis of idiopathic PD was conducted. Notes of all donors who used apomorphine via continuous infusion for at least three months were reviewed. Clinical and demographic data were collected, as well as detailed information on treatment, prevalence and outcomes of ICBs. Results: 193 PD cases, 124 males and 69 females, with an average age at disease onset of 60.2 years and average disease duration of 17.2 years were reviewed. Dementia occurred in nearly half of the sample, depression in one quarter, and dyskinesias in a little over 40%. The prevalence of ICBs was 14.5%. Twenty-four individuals used apomorphine infusion for more than three months. Patients on apomorphine had younger age at disease onset, longer disease duration, and higher prevalence of dyskinesias. The prevalence of de novo ICB cases among patients on apomorphine was 8.3%. Apomorphine infusion was used for an average of 63.1 months on an average maximum dose of 79.5 mg per day. Ten patients remained on apomorphine until death. Conclusions: Apomorphine can be used as an alternative treatment for patients with previous ICBs as it has low risk of triggering recurrence of ICBs.

RESUMO Antecedentes: Comportamentos impulsivo-compulsivos (CICs) podem acometer uma parcela significativa de indivíduos com doença de Parkinson (DP). Objetivo: Nós estudamos amostras de tecido cerebral de uma população de pacientes com DP de um banco de cérebros que receberam apomorfina por infusão contínua em vida, com a finalidade de avaliar a prevalência e o desfecho dos CICs. Métodos: Uma pesquisa no banco de dados do Banco de Cérebros de Queen Square foi conduzida à procura de doações recebidas entre 2005 e 2016 com diagnóstico anatomopatológico de DP idiopática. Os prontuários de todos os doadores que usaram apomorfina por infusão contínua por um período mínimo de três meses foram revisados. Dados clínicos e demográficos foram coletados, assim como informações detalhadas sobre o tratamento, prevalência e desfecho dos CICs. Resultados: 193 casos de DP, 124 do sexo masculino e 69 do sexo feminino, com idade média de início da doença de 60,2 anos e tempo médio de duração da doença de 17,2 anos, foram revisados. Aproximadamente metade dos casos apresentaram demência, um quarto depressão, e um pouco mais de 40% discinesias. A prevalência de CICs foi 14,5%. Vinte e quatro indivíduos usaram infusão de apomorfina por mais de três meses. Os pacientes que usaram apomorfina apresentaram DP mais cedo, maior duração da doença, e uma maior prevalência de discinesias. A prevalência de novos casos de CICs entre pacientes usando apomorfina foi de 8,3%. Infusão de apomorfina foi usada em média por 63,1 meses a um dose máxima média de 79,5 mg por dia. Dez pacientes permaneceram usando apomorfina até o óbito. Conclusões: Apomorfina pode ser usada como opção de tratamento alternativo para pacientes que apresentarem CICs no passado considerando seu baixo risco de causar recorrência de CICs.

Clomipramina no tratamento da perseguição compulsiva da cauda em Bull Terrier - relato de caso / Clomipramine in the treatment of compulsive tail pursuit in bull terrier - case report

A perseguição compulsiva da cauda consiste em um distúrbio caracterizado por movimentos giratórios em círculos, lentos a rápidos com ou sem foco na cauda. É uma desordem comportamental comumente observada em cães da raça Bull Terrier, sendo mais frequente em machos, com início entre três e seis meses de idade. O diagnóstico é realizado com base no histórico do paciente junto com exames físico, neurológico e laboratoriais. O tratamento pode ser feito por meio do manejo ambiental e da retirada de fatores estressantes aliados a medicamentos antidepressivos. O objetivo deste artigo é relatar o caso de um Bull Terrier que apresentava perseguição compulsiva da cauda e teve evidente melhora clínica 75 dias após início do tratamento com clomipramina. A melhora foi ainda maior após a orquiectomia. A clomipramina consiste em um antidepressivo tricíclico promissor no tratamento de perseguição compulsiva da cauda em cães, devendo-se associar alteração no manejo ambiental e evitar gatilhos que induzam frustração, ansiedade e conflito.(AU)

The compulsive pursuit of the tail is characterized by a rotating movement in circles, slow to fast with or without focus on the tail. It is a disorder commonly observed in bull terrier dogs, being more frequent in males, beginning between 3 and 6 months of age. Diagnosis can be made based on patient history along with physical, neurological, and laboratory tests. Treatment can be done through environmental management and withdrawal of stressors allied with antidepressant drugs. The objective of this article is to report the case of a Bull Terrier that had compulsive pursuit of the tail and had evident clinical improvement 75 days after starting treatment with clomipramine. The improvement was even greater after orchiectomy. Clomipramine is the promising tricyclic antidepressant in the treatment of compulsive tail chasing in dogs. It should be associated with changes in environmental management and avoid triggers that induce frustration, anxiety and conflict.(AU)

The impact of the SSRIs on personality traits and compulsive behaviors - Case reports

Some personality traits and compulsive behaviors can been affected by the SSRIs. Five personality traits and/or compulsive behaviors were selected for study: 1) interpersonal sensitivity; 2)perfectionism; 3) irratability/impulsivity; 4) pathological jealousy and 5) compulsions to exercise and/or to work. Five cases are reported in which the effects of SSRIs (fluoxetine or paroxetine) may have induced personality changes. Perfectionism, pathological jealousy and compulsions to exercise and/or to work were markedly altered
