ResumenAbstract original adicciones vol. xx, nº x · 2020La falta de consenso sobre si el consumo de cannabis favorece la neurocognición en pacientes con diagnóstico de esquizofrenia consumidores de esta sustancia, más los problemas metodológicos encontion in these patients, techniques such as fMRI and EEG have found brain impairment. Furthermore, regarding schizophrenia-diagnosed patients who use cannabis, some studies have shown less deterioration among cognitive domains, which may apparently be related with one of its components (CBD). Measuring brain connectivity can be useful for clarifying neurophysiological mechanisms of cognition in marihuana-using schizophrenia patients. Cognitive decline is generalized in schizophrenia patients and is considered fundamental for disease physiopathology.

Severe mental disorders continue to challenge and worry mental health professionals and researchers. The search for the underlying etiology, the fundamental pathophysiology, and the definitive treatment for these is still ongoing. Neuroimaging technologies contribute to the understanding of mental disorders and may emerge as a diagnostic tool. For this article, information on how severe mental illness has been studied using brain connectivity was tracked in the Web of Science database. After obtaining the results, the Tree of Science platform was used for bibliographic analysis. A general view of the topic of brain connectivity in mental illness was drawn, and some of the most critical findings in this search are presented. Some important aspects are discussed, such as the fact that the biological mechanisms that have been proposed to understand mental disorders, mainly mood disorders, generally had not included a neuropathological component. Finally, it is concluded that it is necessary to approach these disorders from transdisciplinary perspectives such as neuropsychiatry.

El objetivo de la investigación fue establecer las diferencias en el rendimiento frontal y ejecutivo en sujetos de 7 a 12 años que se encuentran en proceso de restablecimiento de derecho a cargo del Instituto Colombiano de Bienestar Familiar(ICBF) en la Clínica del Oriente, en comparacion con niños y adolescentes que viven con su familia biológica. En total, la muestra estuvo constituida por 40 niños, 20 en cada uno de los grupos mencionados. La evaluación se realizó mediante el Test Breve de Inteligencia de Kauffman (K-BIT) y la Batería Neuropsicológica de las Funciones Ejecutivas y Lóbulos Frontales (BANFE). Los resultados evidencian diferencias entre ambos grupos en las funciones de planeación, seguimiento de reglas, flexibilidad mental y memoria de trabajo.
