Abstract
Las conclusiones aportadas por la literatura clásica que ha abordado el estudio de las relaciones existentes entre un consumo habitual de cannabis y el rendimiento neuropsicológico no son concluyentes. El objetivo de este trabajo se ha centrado, por un lado, en analizar en qué medida afecta el consumo diario de cannabis a las funciones cognitivas de atención, memoria y funciones ejecutivas, y, por otro lado, al análisis de la relación existente entre la percepción subjetiva del funcionamiento cognitivo de los participantes, y el rendimiento real medido a partir de pruebas estandarizadas. Participaron un total de 20 jóvenes de entre 20 y 30 años, a quienes se les administró un cuestionario de autopercepción, y una serie de pruebas neuropsicológicas. Los resultados muestran que existe un déficit significativo en los componentes de atención selectiva, control inhibitorio, memoria operativa, aprendizaje, y recuperación de información de la MLP. Sin embargo, no se hallan diferencias estadísticamente relevantes para los componentes de atención sostenida, atención alternante, atención dividida, y flexibilidad cognitiva. Por otro lado, no se aprecia una relación estadísticamente significativa entre la autopercepción, y el rendimiento real.
The conclusions provided by the classic literature that has addressed the study of the relationship between regular cannabis use and neuropsychological performance are not 4 conclusive. The aim of this research has focused, on the one hand, on analyzing the extent to which daily cannabis consumption affects the cognitive functions of attention, memory and executive functions, and, on the other hand, on the analysis of the relationship between the subjective perception of cognitive functioning of the participants, and the actual performance measured from standardized tests. A total of 20 young people between 20 and 30 years of age participated, who were administered a self-perception questionnaire and a series of neuropsychological tests. The results show that there is a significant deficit in the selective attention, inhibitory control, working memory, learning, and information retrieval components of the MLP. However, no statistically relevant differences were found for the components of sustained attention, alternating attention, divided attention, and cognitive flexibility. On the other hand, there is no statistically significant relationship between selfperception and actual performance.
