6 de agosto de 2018 actualizado por: Jae-Hong Lee, Asan Medical Center

A Prospective, Three-arm, Parallel Design, Controlled Trial to Assess Efficacy of Cognitive Training in Subjective Memory Impairment

This study evaluates the efficacy of cognitive training in subjects with subjective memory impairment. The first group will receive cognitive training and lifestyle modification in combination, the second group will receive only lifestyle modification, and the third group will receive no intervention.

Descripción general del estudio

Descripción detallada

Subjective memory impairment is currently thought to be a risky state of progression to Alzheimer's disease. This study aims to confirm whether cognitive training in subjective memory impairment would show improvement in the subjective and objective cognition. We include subjects with normal cognition but complained subjective feeling of memory decline and conduct cognitive training programs combined with lifestyle modifications for 3 months. We evaluate the neuropsychological tests and questionnaires about subjective improvement after 3 months of interventions.
