RESUMO
La correcta identificación de las emociones básicas (alegría, miedo, asco, tristeza, sorpresa e ira) desempeña un importante papel en las relaciones sociales y conductas ligadas a la propia supervivencia. En la Enfermedad de Alzheimer (EA) la capacidad de reconocimiento emocional podría estar ya alterada en fases iniciales. Por ello, el objetivo principal del presente trabajo fue realizar una revisión sistemática de la literatura acerca del reconocimiento emocional en personas con EA, identificando posibles variables moduladoras. Se realizó una búsqueda en las bases de datos Web of Science y PsycINFO. Después de aplicar los criterios de inclusión-exclusión se seleccionaron un total de 28 artículos. Las imágenes estáticas fueron los estímulos más utilizados para evaluar el reconocimiento de las emociones básicas, especialmente las fotografías desarrolladas por Paul Ekman y colaboradores. Los resultados de la revisión indican que las personas con EA generalmente muestran déficit del reconocimiento emocional, aunque los datos no son concluyentes. Ello podría estar relacionado con la diversidad de metodologías aplicadas. En relación con las variables evaluadas (sexo y edad) se pone de manifiesto la necesidad de futuras investigaciones que estudien de forma sistemática cómo estos factores pueden modular el reconocimiento emocional en pacientes con EA.(AU)
The correct identification of basic emotions (joy, fear, disgust, sadness, surprise and anger) plays an important role in social relationships and behaviors linked to one's survival. In Alzheimer's disease (AD), the ability to recognize emotions may already be impaired at early stages of the disease. Therefore, the main objective of the present study was to carry out a systematic review of the literature on facial emotional recognition in people with AD, identifying possible modulating variables. A search on the Web of Science and PsycInfo databases was carried out. After applying the inclusion-exclusion criteria, a total of 28 articles were selected. Static images were the most used stimuli to evaluate the recognition of basic emotions, especially the photographs developed by Paul Ekman and collaborators. Results of the present review indicate that people with AD generally display deficits in emotional recognition, although data are not conclusive, which could be related to the diversity of methodologies applied. In relation to the variables evaluated (sex and age), the need of further research in order to study how these factors could modulate emotional recognition in AD patients is highlighted.(AU)

BACKGROUND: The study of emotion recognition could be crucial for detecting alterations in certain cognitive areas or as an early sign of neurological disorders. OBJECTIVE: The main objective of the study is to characterize research development on emotion recognition, identifying the intellectual structure that supports this area of knowledge, and the main lines of research attracting investigators' interest. METHODS: We identified publications on emotion recognition and dementia included in the Web of Science Core Collection, analyzing the scientific output and main disciplines involved in generating knowledge in the area. A co-citation analysis and an analysis of the bibliographic coupling between the retrieved documents elucidated the thematic orientations of the research and the reference works that constitute the foundation for development in the field. RESULTS: A total of 345 documents, with 24,282 bibliographic references between them, were included. This is an emerging research area, attracting the interest of investigators in Neurosciences, Psychology, Clinical Neurology, and Psychiatry, among other disciplines. Four prominent topic areas were identified, linked to frontotemporal dementia, autism spectrum disorders, Alzheimer's disease, and Parkinson's and Huntington disease. Many recent papers focus on the detection of mild cognitive impairment. CONCLUSION: Impaired emotion recognition may be a key sign facilitating the diagnosis and early treatment of different neurodegenerative diseases as well as for triggering the necessary provision of social and family support, explaining the growing research interest in this area.
