¿Influye el trauma infantil en el reconocimiento de las emociones faciales independientemente del diagnóstico de trastorno mental grave? / Can childhood trauma influence facial emotion recognition independently from a diagnosis of severe mental disorder?

INTRODUCCIÓN: El reconocimiento de las expresiones faciales (REF) es un componente fundamental en la interacción social. Sabemos que dicho REF se encuentra alterado tanto en los pacientes con trastorno mental grave (TMG) como en los que padecen antecedentes de trauma infantil. MATERIAL Y MÉTODOS: Pretendemos analizar la posible relación entre la existencia de trauma en la infancia más allá de la presencia de un TMG, medido mediante la escala CTQ y el reconocimiento de las expresiones faciales, en una muestra con tres tipos de sujetos (n=321): controles sanos (n=179), pacientes con TLP (n=69) y primeros episodios psicóticos (n=73). Así mismo, se recogieron variables clínicas y datos sociodemográficos. Se analizó dicha relación mediante una técnica de regresión multivariante ajustando por el sexo, la edad, el CI, el consumo actual de tóxicos y el grupo al que pertenece el sujeto. RESULTADOS: El trauma sexual y/o físico en la infancia se relacionó de forma independiente de la existencia de TMG con un peor ratio de REF total, además de con una peor tasa de reconocimiento en las expresiones de felicidad. Además, los sujetos con antecedentes de trauma en la infancia atribuyeron con mayor frecuencia expresiones de enfado y miedo a las caras neutras y felices, independientemente de otras variables. CONCLUSIONES: La existencia de trauma en la infancia parece influir de manera independiente al TMG en la capacidad de los sujetos de reconocer expresiones faciales. Dado que el trauma es un factor prevenible y con un tratamiento específico, se debería prestar atención a la existencia de este antecedente en las poblaciones clínicas

INTRODUCTION: Facial emotion recognition (FER) is a fundamental component in social interaction. We know that FER is disturbed in patients with severe mental disorder (SMD), as well as those with a history of childhood trauma. MATERIAL AND METHODS: We intend to analyze the possible relationship between the existence of trauma in childhood irrespective of a SMD, measured by the CTQ scale and facial expression recognition, in a sample of three types of subjects (n=321): healthy controls (n=179), patients with BPD (n=69) and patients with a first psychotic episode (n=73). Likewise, clinical and socio-demographic data were collected. The relationship was analyzed by a technique of multivariate regression adjusting for sex, age, IQ, current consumption of drugs and group to which the subject belonged. RESULTS: Sexual and/or physical trauma in childhood related independently to the existence of SMD with a worse total FER ratio, as well as to a worse rate of recognition in expressions of happiness. Furthermore, the subjects with a history of childhood trauma attributed expressions of anger and fear more frequently to neutral and happy faces, irrespective of other variables. CONCLUSIONS: The existence of trauma in childhood seems to influence the ability of subjects to recognize facial expressions, irrespective of SMD. Trauma is a preventable factor with specific treatment; therefore, attention should be paid to the existence of this background in clinical populations

The relationship between theory of mind deficits and neurocognition in first episode-psychosis.

Research suggests that theory of mind (ToM) deficits are related to chronic psychosis and to first-episode psychosis (FEP) independently of other neurocognition domains. The aim of this study was to measure the differences in ToM area in a Spanish population of FEP sample (N = 32) and in a healthy control group (N = 32). A further aim was to describe the relationship between different domains of neurocognition, psychotic symptoms and social functioning with ToM in this sample. ToM was assessed with the MASC task. Estimated IQ with a short version of the WAIS III, Rey-Osterrieth Complex figure, Trail Making Test, Stroop test and Wisconsin Carting Sorting test were used to assess neurocognition. Psychotic symptoms were assessed with Community Assessment of Psychic Experiences (CAPE) in both groups and with PANSS scale in FEP group. GAF and Cannon-Spoor scales were used to measure social functioning before and after onset of psychosis. FEP showed important deficits in ToM domain compared to controls. A worse executive functioning was associated with worse scores in ToM task. However, no relation was found between positive or negative psychotic symptoms and ToM or social functioning and ToM. In our sample neurocognition tests were strongly related to ToM domain independently of other variables.

Differences in Facial Emotion Recognition between First Episode Psychosis, Borderline Personality Disorder and Healthy Controls.

BACKGROUND: Facial emotion recognition (FER) is essential to guide social functioning and behaviour for interpersonal communication. FER may be altered in severe mental illness such as in psychosis and in borderline personality disorder patients. However, it is unclear if these FER alterations are specifically related to psychosis. Awareness of FER alterations may be useful in clinical settings to improve treatment strategies. The aim of our study was to examine FER in patients with severe mental disorder and their relation with psychotic symptomatology. MATERIALS AND METHODS: Socio-demographic and clinical variables were collected. Alterations on emotion recognition were assessed in 3 groups: patients with first episode psychosis (FEP) (n = 64), borderline personality patients (BPD) (n = 37) and healthy controls (n = 137), using the Degraded Facial Affect Recognition Task. The Positive and Negative Syndrome Scale, Structured Interview for Schizotypy Revised and Community Assessment of Psychic Experiences scales were used to assess positive psychotic symptoms. WAIS III subtests were used to assess IQ. RESULTS: Kruskal-Wallis analysis showed a significant difference between groups on the FER of neutral faces score between FEP, BPD patients and controls and between FEP patients and controls in angry face recognition. No significant differences were found between groups in the fear or happy conditions. There was a significant difference between groups in the attribution of negative emotion to happy faces. BPD and FEP groups had a much higher tendency to recognize happy faces as negatives. There was no association with the different symptom domains in either group. CONCLUSIONS: FEP and BPD patients have problems in recognizing neutral faces more frequently than controls. Moreover, patients tend to over-report negative emotions in recognition of happy faces. Although no relation between psychotic symptoms and FER alterations was found, these deficits could contribute to a patient's misinterpretations in daily life.
