O.; SOEIRO-DE-SOUZA, M.; MORENO, D.; MORENO, R. A.Objective: Bipolar disorder (BD) is characterized by high levels of childhood trauma as well as of cognitive dysfunction. Our aim is to investigate the association between these two factors in bipolar patients and in healthy controls. Methods: A total of 35 patients with BD in euthymia, aged between 18 and 40 years old, were recruited at Hospital das Clinicas in São Paulo, Brazil. Ninety four healthy volunteers (HC) (predominantly medical students) aged between 18 and 40 years old, with no current or past history of psychiatric disorder, were recruited from the University of São Paulo. Information about early life stress was obtained using the Childhood Trauma Questionnaire (CTQ). Cognitive function was assessed through a comprehensive and standardized neuropsychological test battery, including social cognition – Facial Emotional Recognized (FER). Results: In the BD group we observed: that physical abuse was significantly associated with reduced scores on verbal recall (p = 0.04) and with fewer recognized of “fear” faces (p = 0.02); sexual abuse and physical neglect were significantly associated with reduced scores on executive function scales (p = 0.02 to p = 0.04); emotional neglect was significantly associated only with reduced scores on recognized of “anger” faces; emotional abuse was significantly associated with reduced scores on attentional process (p = 0.02), verbal task from the Wechsler Abbreviated Scale of Intelligence (WASI) (p = 0.01), and recognized “anger” faces; pshysical neglect was yet significantly associated with reduced scores on verbal and performance tasks and IQ from the WASI (p = 0.02 to p < 0.001), and FER scores on the Emotion Hexagon (Hx) tests and e Ekman 60 Faces (EK60) total scores. In the control HC, Emotional Neglect and Physical Neglect was significantly associated with reduced scores on verbal and performance tasks and IQ from the WASI (p = 0.02 to p < 0.001), working memory (p = 0.01) and executive function (p = 0.01to p = 0.007); Emotional Neglect and Sexual Abuse was significantly associated with reduced scores on verbal fluency; and significantly reduced scores on FER was observed in emotional abuse (p = 0.03), Physical Neglect (p = 0.04 to p = 0.008) and Sexual Abuse (p = 0.04). Discussion: Our results indicate that childhood trauma is associated with a reduction in cognitive function across cognitive domains in patients with BD and HC, in particular social cognition, working memory and executive function as well as general cognition.conferenceObject Influence of childhood trauma on personality development in bipolar patients and healthy controls(2013) MONTEIRO, R.; BIO, D. Soares; SOEIRO-DE-SOUZA, M.; MISSIO, G.; MORENO, D.; MORENO, R. A.Objective: Bipolar disorder (BD) is characterized by high levels of childhood trauma and they can be detrimental in relation to the formation of personality. The aim of this study is to investigate the association between childhood trauma and BD personality compared to healthy controls (HC). Methods: A total of 27 euthimic BD patients, aged between 18 and 40 years old, were recruited at Hospital das Clinicas in São Paulo, Brazil. Twenty HC (predominantly medical students) aged between 18 and 35 years old, with no current or past history of psychiatric disorder, were recruited from the University of São Paulo. Information about early life stress was obtained using the Childhood Trauma Questionnaire (CTQ). Personality Formation was assessed through NEO-PI-R personality test – based on the Big Five personality traits: Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness to Experience. Results: In the BD group the main significant associations were: physical abuse with concientiousness (p = 0.03); emotional neglect with agreeableness (p =0.03) and emotional abuse with conscientiousness (p = 0.04). There were no significant differences in HC group. Comparing BD and HC physical abuse was associated with concientiousness (p = 0.03) and emotion Neglecent was associated with agreeableness (p = 0.03). Discussion: Our results indicate that childhood trauma can be associated with personality traits in BD patients but not in HC, mainly regarding concientiousness and emotional neglect.- MRI investigation of a 6-week trial of lithium in medication-free patients with bipolar depression(2014) ZANETTI, M.

H.; MORENO, R. A.Background: One of the many cognitive deficits reported in Bipolar Disorder (BD) patients is facial emotion recognition (FER), which has recently been associated with dopaminergic catabolism. Catechol-O-methyltransferase (COMT) is one of the main enzymes involved in the metabolic degradation of dopamine (DA) in the prefrontal cortex (PFC). The COMT gene polymorphism rs4680 (Val 158 Met) Met allele is associated with decreased activity of this enzyme in healthy controls. The objective of this study was to evaluate the influence of Val158 Met on FER during manic and depressive episodes in BDI patients and in healthy controls. Materials & Methods: 64 BD type I patients (39 in manic and 25 in depressive episodes) and 75 healthy controls were genotyped for COMT rs4680 and assessed for FER using the Ekman 60 Faces (EK60) and Emotion Hexagon (Hx) tests. Results: Bipolar manic patients carrying the Met allele recognized fewer surprised faces, while depressed patients with the Met allele recognized fewer angry and happy faces. Healthy homozygous subjects with the COMT Met allele had higher FER scores on the Hx total score, as well as on disgust and angry faces than other genotypes. Conclusion: This is the first study suggesting that COMT rs4680 modulates FER differently during BD episodes and in healthy controls. This provides evidence that PFC DA is part of the neurobiological mechanisms of social cognition. DA receptor stimulation alterations during BD mood episodes might explain the contrasting results found in BD compared to controls. Further studies on other COMT polymorphisms that include euthymic BD patients are warranted.
