Resumen
Introducción: la depresión es un trastorno psiquiátrico prevalente que impacta significativamente la calidad de vida de los individuos afectados. A pesar de los avances en los tratamientos farmacológicos, existen limitaciones tanto en su eficacia como en la duración de sus efectos terapéuticos. En este contexto, la psilocibina ha emergido como una herramienta prometedora en intervenciones psicoterapéuticas asistidas, lo que ha impulsado un creciente interés en su estudio dentro de modelos clínicos integrados.
Materiales y métodos: se realizó una revisión de la literatura actual sobre los efectos de la psilocibina en el tratamiento de la depresión. Se incluyeron estudios clínicos y experimentales que documentan los efectos cognitivos y conductuales de la psilocibina en voluntarios sanos y en pacientes con trastorno depresivo mayor, así como los mecanismos moleculares involucrados.
Resultados: los estudios revisados sugieren que la psilocibina modula los receptores de serotonina 5-HT2A y reorganiza las redes cerebrales asociadas con el procesamiento emocional y la autorregulación. Las pruebas neuropsicológicas iniciales indican que la psilocibina facilita la presencia de un sesgo positivo en el procesamiento emocional.
Discusión: los hallazgos indican que la psilocibina no solo presenta efectos antidepresivos, sino que también promueve una mayor adaptación psicológica mediante la modificación de la conectividad cerebral. La combinación de psilocibina con psicoterapia podría potenciar los cambios en la flexibilidad psicológica y en la regulación emocional.
Conclusiones: la psilocibina muestra un potencial terapéutico relevante en el manejo de la depresión; sin embargo, resulta necesario investigar más a fondo sus efectos a largo plazo y su posible integración en tratamientos convencionales.
