摘　　要：目前,心理学、生物学、社会学等多个学科都在关注认知老化。文章从生物学的角度,论述了线粒体和认知老化的关系;介绍了线粒体在数量、分布及其能量供应,Ca2+浓度的维持,引发神经细胞凋亡,及线粒体基因等几个方面对认知老化产生的影响;描述了老化过程中线粒体功能失常引起的认知障碍;从而,为后人对认知老化产生机制的深入研究提供一定的理论依据。At present, many subjects, such as psychology, biology, sociology, etc, focus their attention on cognitive aging. From the point of view of biology, this paper mainly discussed the relation between the mitochondrion and cognitive aging. The mitochondrion as an important cell organ acts on the cognitive aging in many aspects, such as quantity, distribution, energy supply, Ca2+ concentrations, nerve cell apoptosis, and mitochondrial gene. When mitochondrial functions are abnormal in the aging course, the cognitive function may be influenced by the negative effects. These investigations may offer useful evidences for understanding the cognitive aging mechanism deeply.
