"I Use Weed for My ADHD": A Qualitative Analysis of Online Forum Discussions on Cannabis Use and ADHD.

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) is a risk factor for problematic cannabis use. However, clinical and anecdotal evidence suggest an increasingly popular perception that cannabis is therapeutic for ADHD, including via online resources. Given that the Internet is increasingly utilized as a source of healthcare information and may influence perceptions, we conducted a qualitative analysis of online forum discussions, also referred to as threads, on the effects of cannabis on ADHD to systematically characterize the content patients and caregivers may encounter about ADHD and cannabis. METHODS: A total of 268 separate forum threads were identified. Twenty percent (20%) were randomly selected, which yielded 55 separate forum threads (mean number of individual posts per forum thread = 17.53) scored by three raters (Cohen's kappa = 0.74). A final sample of 401 posts in these forum threads received at least one endorsement on predetermined topics following qualitative coding procedures. RESULTS: Twenty-five (25%) percent of individual posts indicated that cannabis is therapeutic for ADHD, as opposed to 8% that it is harmful, 5% that it is both therapeutic and harmful, and 2% that it has no effect on ADHD. This pattern was generally consistent when the year of each post was considered. The greater endorsement of therapeutic versus harmful effects of cannabis did not generalize to mood, other (non-ADHD) psychiatric conditions, or overall domains of daily life. Additional themes emerged (e.g., cannabis being considered sanctioned by healthcare providers). CONCLUSIONS: Despite that there are no clinical recommendations or systematic research supporting the beneficial effects of cannabis use for ADHD, online discussions indicate that cannabis is considered therapeutic for ADHD-this is the first study to identify such a trend. This type of online information could shape ADHD patient and caregiver perceptions, and influence cannabis use and clinical care.

Investigating the developmental and behavioral consequences of maternal immune activation on affected offspring

Maternal infection during pregnancy increases the risk of several neuropsychiatric disorders later in life, many of which have a component of dopaminergic (DA) dysfunction, including schizophrenia, autism spectrum disorders (ASD), and attention deficit hyperactivity disorder (ADHD). The majority of DA neurons are found in the adult midbrain; as such the midbrain is a key region of interest regarding these disorders. The literature is conflicting regarding the behavioral alterations following maternal immune activation (MIA) exposure, and the cellular and molecular consequences of MIA on the developing midbrain remain to be fully elucidated. Thus, this thesis aimed to establish the consequences of acute and mild MIA on offspring dopamine-related behaviors, as well as the associated cellular and molecular disturbances of MIA on offspring midbrains. We utilized a rat model of MIA using low dose (50μg/kg, I.P.) of LPS administered at different gestational ages. Our first study indicated that MIA at later gestational ages significantly increased pro-inflammatory IL-1β expression, and reduced HSD11B2 expression in the placenta, which is an important regulator of fetal development. In utero LPS exposure at later gestational ages also impaired the growth of neurons from affected offspring. This study identified key gestational stages during which MIA resulted in differential effects. We utilized these time points in subsequent studies, the next of which investigated neurobehavioral outcomes following MIA. Our results from that study showed that motor differences occurred in juvenile offspring following MIA at E16 only, and these differences were compensated for in adolescence. Then, there was a decline in motor behavior capabilities in adulthood, again only for animals exposed to MIA on E16 (and not E12). Furthermore, our results also demonstrated adolescent and adult offspring that were exposed to MIA at E12 had diminished responses to amphetamine in reward seeking behaviors. In our final study, we aimed to investigate the molecular and cellular changes following MIA which might explain these behavioral alterations. This final study showed a differential inflammatory response in fetal midbrains depending on gestational age of exposure as well as differential developmental alterations. For example, LPS exposure at E16 resulted in decreased VM neurosphere size after 7DIV and this was associated with an increased susceptibility to neurotoxic effects of pro-inflammatory cytokines for VM neurospheres and VM DA neurons treated in culture. In utero LPS exposure at E16 also reduced DA neuron count of fetal VM, measured by TH staining. However, there were no differences in DA neuron number in juvenile, adolescent, or adult offspring. Similarly, LPS exposure did not alter cell number or morphology of glial cells in the midbrains of affected offspring. In conclusion, this thesis indicated later rat pregnancy (E16) as vulnerable time for MIA to affect the development of the nigrostriatal pathway and subsequent behavioral outcomes, possibly implicating a role for MIA in increased risk for disorders associated with motor behavior, like PD. These effects may be mediated through alterations in the placenta and altered inflammatory mediators in the offspring brain. This thesis has also shown that MIA in earlier rat pregnancy (E12) results in altered mesocorticolimbic function, and in particular MIA on E12 resulted in a differential response to amphetamine in affected offspring, which may implicate a role for MIA in increasing the risk for disorders associated with this pathway, including drug tolerance and addiction.

Reward circuitry dysfunction in psychiatric and neurodevelopmental disorders and genetic syndromes: animal models and clinical findings.

This review summarizes evidence of dysregulated reward circuitry function in a range of neurodevelopmental and psychiatric disorders and genetic syndromes. First, the contribution of identifying a core mechanistic process across disparate disorders to disease classification is discussed, followed by a review of the neurobiology of reward circuitry. We next consider preclinical animal models and clinical evidence of reward-pathway dysfunction in a range of disorders, including psychiatric disorders (i.e., substance-use disorders, affective disorders, eating disorders, and obsessive compulsive disorders), neurodevelopmental disorders (i.e., schizophrenia, attention-deficit/hyperactivity disorder, autism spectrum disorders, Tourette's syndrome, conduct disorder/oppositional defiant disorder), and genetic syndromes (i.e., Fragile X syndrome, Prader-Willi syndrome, Williams syndrome, Angelman syndrome, and Rett syndrome). We also provide brief overviews of effective psychopharmacologic agents that have an effect on the dopamine system in these disorders. This review concludes with methodological considerations for future research designed to more clearly probe reward-circuitry dysfunction, with the ultimate goal of improved intervention strategies.

Obstetric mode of delivery and child psychological development

Background/aims: Objective of the current thesis is to investigate the potential impact of birth by Caesarean section (CS) on child psychological development, including autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), behavioural difficulties and school performance. Structure/methods: Published literature to date on birth by CS, ASD and ADHD was reviewed (Chapter 2). Data from the UK Millennium Cohort Study (MCS) were analysed to determine the association between CS and ASD, ADHD and parent-reported behavioural difficulties (Chapter 3). The Swedish National Registers were used to further assess the association with ASD, ADHD and school performance (Chapters 4-6). Results: In the review, children born by CS were 23% more likely to be diagnosed with ASD after controlling for potential confounders. Only two studies reported adjusted estimates on the association between birth by CS and ADHD, results were conflicting and limited. CS was not associated with ASD, ADHD or behavioural difficulties in the UK MCS. In the Swedish National Registers, children born by CS were more likely to be diagnosed with ASD or ADHD. The association with elective CS did not persist when compared amongst siblings. There was little evidence of an association between birth by elective CS and poor school performance. Children born by elective CS had slight reduction in school performance. Conclusions: The lack of association with the elective CS in the sibling design studies indicates that the association in the population is most probably due to confounding. A small but significant association was found between birth by CS and school performance. However, the effect may have been due to residual confounding or confounding by indication and should be interpreted with caution. The overall conclusion is that birth by CS does not appear to have a causal relationship with the aspects of child psychological development investigated.

Personcentrerad omvårdnad för familjer där barn har ADHD En litteraturstudie

Bakgrund: Attention deficit hyperactivity disorder (ADHD) är den vanligaste neuropsykiatriska diagnosen bland barn, prevalens ca 5%. ADHD kan skapa en myriad svårigheter som ibland är svåra att koppla till kärnsymtomen. Miljö och bemötande är viktiga faktorer. Syfte: Syftet med följande studie har varit att beskriva hur specialistsjuksköterskan i psykiatrisk vård kan anpassa den personcentrerade omvårdnaden för barn och familjer där barn har ADHD. Metod: Litteraturstudie av tolv kvalitativa artiklar. Resultat: Tre huvudteman och tre underteman identifierades, 1)Problem, svårighet och avsaknad med underteman; medicinering, psykosocialt och information. 2) Insats, stöd och behov 3) Sjuksköterskeinsats. Svårigheter kring medicinering, kränkningar och att hitta eftersökt information ses. Behovet av struktur, förstående nyckelpersoner och information i ett familjeperspektiv är stort. Sjuksköterskeinsatsen är mångfacetterad, den innefattar att fånga upp och förstå de problem och svårigheter patienten upplever, utbilda, förklara och ge saklig information i ett sociokulturellt kontext till patient och familj. Slutsats: Psykiatrisjuksköterskan måste känna till och respektera varje individs upplevelse av vad som är problemskapande. Struktur, förutsägbarhet, kunskap och en förstående omgivning är nyckelfaktorer för att skapa god personcentrerad omvårdnad för familjer där barn har ADHD.

How do Young People with ADHD Perceive their Condition: An Interpretative Phenomenological Analysis

Attention Deficit Hyperactivity Disorder (ADHD) is one the most prevalent of childhood diagnoses. There is limited research available from the perspective of the child or young person with ADHD. The current research explored how young people perceive ADHD. A secondary aim of the study was to explore to what extent they identify with ADHD. Five participants took part in this study. Their views were explored using semi-structured interviews guided by methods from Personal Construct Psychology. The data was analysed using Interpretative Phenomenological Analysis (IPA). Data analysis suggests that the young people’s views of ADHD are complex and, at times, contradictory. Four super-ordinate themes were identified: What is ADHD?, The role and impact of others on the experience of ADHD, Identity conflict and My relationship with ADHD. The young people’s contradictory views on ADHD are reflective of portrayals of ADHD in the media. A power imbalance was also identified where the young people perceive that they play a passive role in the management of their treatment. Finally, the young people’s accounts revealed a variety of approaches taken to make sense of their condition.

A violência escolar e a sua relação com diferentes psicopatologias

Desde há alguns anos a esta parte, muito se tem discutido a temática do Bullying nas atuais sociedades modernas e industrializadas. Com o avanço da técnica e do conhecimento científico, só recentemente se lhe dá a devida atenção, dado os danos que pode causar a médio e longo prazo em todos os intervenientes nesse fenómeno de exteriorização da violência. Embora se tenham desenhado múltiplas estratégias para a sua explicação e combate, continua a ser um tema muito atual, pois embora pesem os modelos de intervenção de certa forma já padronizados, há sempre a necessidade de os adaptar ao contexto de cada caso. Desta forma este tema continua e continuará a ser alvo de estudo e aprofundamento. Neste trabalho, analisaremos toda a temática do Bullying, desde a sua conceptualização, passando pela sua etiologia, fatores de risco, intervenientes, bem como o seu diagnóstico, combate e prevenção. Partindo da premissa de que este tema envolve uma série de variáveis que vão para além dos problemas comportamentais e/ou da indisciplina, tais como variáveis culturais, sociofamiliares, escolares, pessoais/psicológicas e psicopatológicas, é nesta ultima variável que iremos focar mais especificamente o nosso trabalho, nomeadamente no estabelecimento de uma correlação entre o Bullying e a Perturbação de Défice de Atenção e Hiperatividade. Nos alunos mais jovens, o défice de atenção com hiperatividade, a depressão bem como a ansiedade, são problemas paralelos ao Bullying. Dado o facto de as crianças com estas caraterísticas serem mais vulneráveis à violência, pois têm dificuldades de integração no seio escolar e/ou no grupo de pares, podemos afirmar desde já e com bastante veemência que estas pertencem a um grupo com um enorme fator de risco para se envolver em comportamentos relacionados com o Bulliyng em toda a sua abrangência.

Childhood Attention Problems and the Development of Comorbid Symptoms at the Transition to High School: The Mediating Role of Parent and Peer Relationships

Children with Attention-Deficit/Hyperactivity Disorder (ADHD) are at increased risk for the development of depression and delinquent behavior. Children and adolescents with ADHD also experience difficulty creating/maintaining high quality friendships and parent-child relationships, and these difficulties may contribute to the development of co-morbid internalizing and externalizing symptoms in adolescence. However, there is limited research examining whether high quality friendships and parent-child relationships mediate the relation between ADHD and the emergence of these co-morbid symptoms at the transition to high school. This study examines the mediating role of relationship quality in the association between ADHD and depressive symptoms/delinquent behaviors at this developmentally significant transition point. Results revealed significant indirect effects of grade 6 attention problems on grade 9 depressive symptoms through friendship quality and quality of the mother-child relationship in grade 8. Interventions targeting parent and peer relationships may be valuable for youth with ADHD to promote successful transitions to high school.

Relatório de estágio : Centro de Apoio ao Desenvolvimento Infantil, CADIn

O presente relatório descreve a prática profissional desenvolvida no Centro de Apoio ao Desenvolvimento Infantil (CADIn), no âmbito do Ramo de Aprofundamento de Competências Profissionais (RACP), enquadrado no 2º Ano do 2º Ciclo de Reabilitação Psicomotora, correspondente ao ano letivo 2014/2015. O trabalho desenvolvido no CADIn foi realizado, principalmente, junto de crianças e jovens com Dificuldades de Aprendizagem Específicas (DAE). As DAE, de origem neurobiológica e intrínsecas ao indivíduo, caracterizam-se por um conjunto de traços heterogéneos que se manifestam na aquisição e uso das competências auditivas, da fala, da leitura, da escrita, do raciocínio e/ou matemáticas. Podem coexistir com outras perturbações, como é o caso da Perturbação de Hiperatividade e Défice de Atenção (PHDA). A heterogeneidade dos perfis de aprendizagem de crianças com DAE torna o processo de intervenção um desafio permanente. Neste sentido, a intervenção psicomotora surge como uma resposta que permite o desenvolvimento holístico do indivíduo, viabilizando a apropriação dos processos simbólicos. O relatório está organizado em Enquadramento da Prática Profissional, que inclui o Enquadramento Teórico e o Enquadramento Institucional, e Realização da Prática Profissional, onde são abordados dois estudos de caso, de uma forma mais detalhada.

Intervenção do professor titular da sala de aula do primeiro ano do primeiro ciclo perante a inclusão de crianças com Perturbação de Hiperatividade e Défice de Atenção

A Perturbação de Hiperatividade e Défice de Atenção possui três características essenciais: Défice de Atenção, Impulsividade e Hiperatividade. Ou seja, é uma problemática neuro-comportamental, manifestada na infância onde as crianças ostentam um modelo comportamental assente no excesso de atividade motora (hiperatividade), de falta de atenção e de impulsividade. Torna-se necessário então que, o professor adopte estratégias de trabalho com estas crianças facilitando assim a sua inclusão. Este estudo tem como principais objetivos: Identificar as opiniões do professor titular da sala de aula do primeiro ano do primeiro ciclo perante a inclusão de crianças com PHDA; Descrever as estratégias do professor titular da sala de aula do primeiro ano do primeiro ciclo perante a inclusão de crianças com PHDA. A orientação metodológica adotada relaciona-se com uma abordagem qualitativa. Este estudo é constituído por 10 professores a quem foi feita uma entrevista para se recolherem os dados. Foi feito o tratamento dos dados, os quais foram analisados e discutidos. As conclusões indicam que, ao nível da formação inicial, as Escolas de Ensino Superior e as Universidades devem incorporar nos seus cursos de Professores do Primeiro Ciclo uma disciplina que aborde exaustivamente, em cada semestre, as Necessidades Educativas Especiais, abrangendo não só a teoria, como também a prática. Sugere-se ainda que exista formação contínua no âmbito das NEE, a começar pelo professor logo após o término do curso superior, independentemente da sua situação profissional, e em cada área escolar, antes do início do ano letivo, depois das turmas estarem formadas, por forma a cada docente participar naquela onde se abordará a NEE ou as NEEs que existirão na sua sala, sendo focadas estratégias de trabalho com estas crianças visando o sucesso escolar. Constatou-se também que a maioria dos entrevistados leva a cabo práticas de integração e de inclusão, embora se perceba alguma confusão entre integração e inclusão.

Registro de pacientes con distrofinopatías en Colombia

INTRODUCCIÓN. La distrofia muscular de Duchenne es una enfermedad neuromuscular con una herencia recesiva ligada al X que afecta a 1 de cada 3500 niños nacidos vivos. Se produce por mutaciones en el gen DMD que codifica para la distrofina. Se caracteriza por manifestaciones clínicas variables típicas de una distrofia muscular proximal progresiva. OBJETIVO. Realizar el primer registro en Colombia de los pacientes identificados con distrofinopatías, teniendo en cuenta características clínicas y paraclínicas, así como las mutaciones causales de esta patología. METODOLOGÍA Es un estudio descriptivo, transversal, de la revisión de historias clínicas de los pacientes con diagnóstico de DMD atendidos en la consulta de Genética de la Universidad del Rosario durante los años 2006 a 2015. RESULTADOS Se identificaron 99 pacientes, de los cuales 56 (56,56%) corresponden al fenotipo Duchenne y 12 (12,12%) al Becker. No fue posible clasificar a 31 pacientes (31,3%) por falta de datos clínicos. La edad de inicio de los síntomas fue en promedio de 4,41 años. Las mutaciones más frecuentes fueron las deleciones (69%), seguidas por las mutaciones puntuales(14%), las duplicaciones (11%) y por otras mutaciones (4%). CONCLUSIONES Este registro de distrofinopatías es el primero reportado en Colombia y el punto de partida para conocer la incidencia de la enfermedad, caracterización clínica y molecular de los pacientes, garantizando así el acceso oportuno a los nuevos tratamientos de medicina de precisión que permitan mejorar la calidad de vida de los pacientes y sus familias.
