“…Mentre la maggior parte degli studi sul REF e stato condotto in persone affette da disturbo schizofrenico o depressivo, solo Bediou et al (2005a ) e Weniger et al (2004), confrontando questi due gruppi, riportano anomalie nel REF specifiche della schizofrenia.…”

“…Tuttavia, altri studi hanno riscontrato un alterato riconoscimento della paura e del disgusto in persone con schizofrenia (Bediou et al, 2005b), ma non nel riconoscimento dellafelicita (Mandal et al, 1998). E stato inoltre riscontrato che in soggetti con schizofrenia in remissione, 1'alterato riconoscimento emotivo delle espressioni facciali coinvolgeva soprattutto le emozioni di tristezza e di rabbia (Bediou et al, 2005a).…”

“…Inoltre, studi di neuro-imaging condotti su tali soggetti hanno evidenziato un'anomalia deH'integrita dei neuroni e una riduzione del volume a carico deiramigdala, dell'insula, del talamo e dell'ippocampo; ovvero gli studi hanno confermato un deficit nell'attivazione del sistema limbico in risposta allo stimolo emotivo (Lee et al, 2002). L'alterato REF nei soggetti schizofrenici contribuisce ad un funzionamento sociale deficitario e potrebbe predire un loro scarso funzionamento cognitivo (Bediou et al, 2005a). Anche gli studi sul riconoscimento delle emozioni nella depressione concludono che il deficit nel REF puo avere un correlato nelle alterazioni del funzionamento interpersonale (Lappanen et al, 2004;Surguladze et al, 2004) con sottese anomalie neurofisiologiche (Mikhailova et al, 1996).…”

“…Although research has described impairments in the processing of positive facial expressions, such as happiness [28,29], the most consistent findings involve negative ones [30][31][32]. Kohler et al [33] found higher error rates for the identification of sad faces than happy ones in SZ.…”

Schizophrenia is one of the most severe psychiatric conditions, often associated with deficits in social cognition. Social cognition deficits are predictors of functionality in patients and involve theory of mind, attributional style, social perception, and emotional processing. In particular, facial emotion processing (an important domain of emotional processing) seems to be particularly related to cognitive and social functioning, and to positive and negative symptoms. Patients with schizophrenia have difficulties in processing emotional faces; however, those impairments are still far from fully understood. In this review, we addressed the behavioural and neural correlates of facial emotion processing in schizophrenia. Despite studies showing impairments in both positive and negative faces, the most consistent findings involved negative faces. Moreover, patients with schizophrenia showed abnormalities in the social brain neural circuit during facial emotion processing. While some studies described hypoactivation of brain areas related to emotional processing, such as the amygdala, others reported hyperactivation, leading to a high number of inconsistencies. The findings are limited by the experimental designs used, and the clinical and demographic characteristics of patients. Despite such variable findings, there has been growing interest in developing psychosocial interventions focused directly on social cognitive impairments in schizophrenia, with potential impact on patient's ability to perceive emotional faces. We provide a critical perspective on current evidence and suggest new pathways of research. The understanding of the mechanisms underlying facial emotion processing in schizophrenia could enhance functionality and quality of life by providing innovative approaches to the interpersonal difficulties patients frequently experience.

Objective: The Accelerator program for Discovery in Brain disorders using Stem cells (ADBS) is a longitudinal study on five cohorts of patients with major psychiatric disorders from genetically high-risk families, their unaffected first-degree relatives, and healthy subjects. We describe the ADBS protocols for acquisition, quality assurance (QA), and quality check (QC) for multimodal magnetic resonance brain imaging studies. Methods:We describe the acquisition and QC protocols for structural, functional, and diffusion images. For QA, we acquire proton density and functional images on phantoms, along with repeated scans on human volunteer. We describe the analysis of phantom data and test-retest reliability of volumetric and diffusion measures.Results: Analysis of acquired phantom data shows linearity of proton density signal with increasing proton fraction, and an overall stability of various spatial and temporal QA measures. Examination of dice coefficient and statistical analyses of coefficient of variation in test-retest data on the human volunteer showed consistency of volumetric and diffusivity measures at whole-brain, regional, and voxel-level. Conclusion:The described acquisition and QA-QC procedures can yield consistent and reliable quantitative measures. It is expected that this longitudinal Pravesh Parekh and Gaurav V.
