“…A more detailed inspection of these impairments revealed that although the sensitivity to detect a specific emotion was preserved, the specificity was affected, ie schizophrenia patients exhibited problems in rejecting faces with other than the target emotional expression . Furthermore, deficits in emotion processing correlate with the severity of psychotic symptoms (Kohler et al, 2000;Schneider et al, 1995). At the same time, they are relatively stable over the course of disease (Addington and Addington, 1998;Kohler et al, 2003) and were reported to be already present in subjects at risk for psychosis (Habel et al, 2004;Kee et al, 2004;Seiferth et al, 2008;van't Wout et al, 2004).…”

“…Focusing on facial emotion perception many studies could show deficits in the processing of emotional facial expressions in schizophrenia patients (Feinberg et al, 1986;Heimberg et al, 1992;Kohler et al, 2003;Mueser et al, 1997;Penn et al, 2000;Schneider et al, 1995Schneider et al, , 2006.

“…Aspects of emotion processing addressed in this context include the perception and expression of one's own emotions and the discrimination of other people's emotions in mimic, gesture, or speech. Accordingly, several studies have demonstrated that deficits in recognizing, assessing, and experiencing emotions are part of the neuropsychological deficit profile of schizophrenia patients (Schneider et al, 1995).…”

Emotion discrimination deficits represent a well-established finding in schizophrenia. Although imaging studies addressed the cerebral dysfunctions underlying emotion perception in adult patients, the question of trait vs state characteristics is still unresolved. The investigation of juvenile patients offers the advantage of studying schizophrenia at an age where influences of illness course and long-term medication are minimized. This may enable a more detailed characterization of emotion discrimination impairments and their cerebral correlates with respect to their appearance and exact nature. A total of 12 juvenile patients with early onset schizophrenia and matched healthy juveniles participated in this study. fMRI data were acquired during an emotion discrimination task consisting of standardized photographs of faces displaying happy, sad, angry, fearful, or neutral facial expression. Similar to findings in adult patients, juvenile patients exhibited reduced performance specificity whereas sensitivity was unaffected. Independent of the valence, their processing of emotional faces was associated with hypoactivations in both fusiform gyri and in the left inferior occipital gyrus. In addition, hyperactivations in patients were found in the right cuneus common to happy, angry, and fearful faces. Further, most distinct changes were present in juvenile patients when processing sad faces. These results point to a dysfunction in cerebral circuits relevant for emotion processing already prominent in adolescent schizophrenia patients. Regions affected by a decrease in activation are related to visual and face processing, similar to deficits reported in adult patients. These changes are accompanied by hyperactivations in areas related to emotion regulation and attribution, possibly reflecting compensatory mechanisms.

The significant impairments in facial expression in individuals with schizophrenia are not due to reduced emotional experience; individuals report emotional experiences equal to or possibly greater than individuals without a psychiatric diagnosis (Herbener, Song, Khine, & Sweeney, 2008;Kring, Kerr, Smith, & Neale, 1993), nor are they simply due to side effects of medication (Earnst et al, 1996;Putnam & Kring, 2007).…”

The expression of emotions and internal states by individuals with severe or profound intellectual disabilities is a comparatively under-researched area. Comprehensive or standardised methods of assessing or understanding the emotions and internal states within this population, whose ability to communicate is significantly compromised, do not exist.The literature base will be discussed and compared to that within the general population.Methods of assessing broader internal states, notably depression, anxiety, and pain within severe or profound intellectual disabilities are also addressed. Finally, this review will examine methods of assessing internal states within genetic syndromes, including hunger, social anxiety and happiness within Prader-Willi, Fragile-X and Angelman syndrome. This will then allow for the identification of robust methodologies used in assessing the expression of these internal states, some of which may be useful when considering how to assess emotions within individuals with intellectual disabilities.

“…Em estudo mais específico no que nos interessa, Frith e col. narraram estórias em que havia componentes afetivos e subjetivos dos personagens e que pacientes esquizofrênicos tinham muito mais dificuldade em recontar estes elementos do que os controles, dando a entender que, assim como os autistas, talvez os esquizofrênicos também tenham um problema com a teoria da mente 19 . Uma outra série de estudos mostra que pacientes esquizofrênicos têm grande dificuldade em lidar com emoções expressas por terceiros e com a repercussão destas sobre o seu próprio psiquismo, sobretudo quando muito pejorativas 20 . Neste estudo relaciona-se a presença de sintomas positivos (delírios, alucinações) com a propensão a se ter os processos cognitivos perturbados por afetos emocionalmente desagradáveis.…”

RESUMO -Testamos o grau de desagregação dislógica do discurso de dez pacientes esquizofrênicos não medicados que narravam fatos carregados emocionalmente ou neutros. As "narrativas emocionais" mostraram-se bem mais dislógicas do que as "narrativas neutras" e, para explicar estes fatos, evocamos: 1)Uma disjunção das conexões fronto-têmporo-límbicas que impediria um tratamento cognitivo adequado das emoções que seriam, desta forma, altamente disruptivas sobre os processos lógicos. 2)Uma disfunção da memória de trabalho/sistema supervisor atencional que induziria tanto a uma perda das conexões normais entre os fragmentos do discurso como a uma ausência de planificação estratégica das linhas globais do enunciado.PALAVRAS-CHAVE: esquizofrenia, transtornos do pensamento, neuropsicologia, psicopatologia, dislogia. Emotionally-loaded narrative increases dyslogia in schizophrenicsABSTRACT -We tested the degree of dyslogia in the narrative of ten schizophrenic non-medicated outpatients while they narrated emotionally-loaded or neutral facts. The "emotional narratives" were much more dyslogic than the "neutral narratives". In order to explain these facts we evoke: 1. A fronto-temporo-limbic connection dysfunction would disturb an adequate cognitive treatement of emotions that would be, in this way, highly disruptive over logical processes. 2. A working memory/supervisory attentional system dysfunction that would produce both a loss of the normal conections among the fragments of speech and a lack of global strategical planning of the thought.KEY WORDS: schizophrenia, thought disorders, neuropsychology, psychopathology, dyslogia.*Médico Psiquiatra-Assistente do Centro Médico-Hospitalar ASMIGO, Médico Psiquiatra-Pesquisador da Universidade Federal de Goiás (UFGO); **Assistente-Médico do Serviço de Psiquiatria ASMIGO (Divisão de Neuropsicologia); ***Médico pós-graduando do Serviço de Neurologia (HC/USP).

No entanto, observa-se hoje que esta concepção está seguramente ultrapassada e sabe-se a contento que estes doentes têm grandes dificuldades intelectuais.Os transtornos formais do pensamento na esquizofrenia só foram claramente elevados a um rol de importância diagnóstica a partir dos estudos de Schneider 3 , que descreveu com proficiência de detalhes a "barragem", o descarrilamento, a disfluência. Para Kraepelin, o sintoma fundamental da esquizofrenia era a apatia e a desvitalização 4 , ao passo que para Bleuler, o segundo grande teórico da doença, os sintomas cognitivos eram fruto secundário de um atentado mais profundo do eu (os sintomas primários). Schneider 5 cunhou o conceito de sintomas de primeira ordem na esquizofrenia, cuja base era o s...
