RESUMEN
La Alteración Cognitiva Leve es un estado de transición entreel envejecimiento normal y la enfermedad de Alzheimer y espor ello una condición de riesgo para la demencia. La serotoninay sus receptores tienen un papel importante en los procesosde aprendizaje y memoria. El receptor 5HT2A está localizadopredominantemente en áreas frontales e hipocampales. En esteestudio hemos valorado la influencia del genotipo del polimorfismoT102C del gen 5HT2A en el rendimiento cognitivo de unamuestra de 59 sujetos con Alteración Cognitiva Leve. Los sujetosheterocigotos (T102/C102) para este polimorfismo puntuabansignificativamente menos en el Mini-Mental, pruebas dememoria visual y verbal y en funciones premotoras, sugiriendoque este genotipo sería un nuevo marcador genético de riesgoen la alteración cognitiva
ABSTRACT
Mild Cognitive Impairment (MCI) is a transitional statebetween normal aging and Alzheimer’s disease and thus, it is ahigh-risk condition for dementia. Serotonin and its receptorsare associated with memory and learning processes. The5HT2A receptor is expressed in prefrontal cortex and hippocampus,above all. We have studied the role of the polymorphismT102C in the 5HT2A gene in cognition in a sample of 59MCI subjects. Those individuals carrying the heterozygous variant(T102/C102) performed significantly worse in the Mini-Mental State Examination, visual and verbal memory tests aswell as premotor functions. These results suggest that this genotypecould be a new genetic risk factor for cognitive impairmentin the elderly
