The paper presents original study results of cognitive changes associated with aging in the absence of neurodegenerative, vascular and other significant for cognition disorders in period from 50 to 85 years. It was shown that aging is associated with moderate memory decrease predominantly because of retrieval deficit but not acquisition insufficiency. It was also shown that aging is associated with non-severe executive dysfunction (lack of planning and control). According usual neuropsychological approaches pattern of cognitive changes described above reflects anterior cortical dysfunction or/and impaired interaction between frontal lobes and subcortical basal ganglia. Shows what physiological changes occur with age in the field of memory and executive functions, which is of great clinical importance for the differential diagnosis of normal aging and early stages of common in the elderly cerebral diseases.
该论文展示了在50至85岁期间,不存在神经退行性、血管性及其他对认知有显著影响的疾病情况下,与衰老相关的认知变化的原始研究结果。结果表明,衰老主要与因检索缺陷而非获取不足导致的中度记忆减退有关。研究还表明,衰老与非严重的执行功能障碍(缺乏计划和控制)有关。根据常见的神经心理学方法,上述认知变化模式反映了前额叶皮质功能障碍或/和额叶与皮质下基底神经节之间的相互作用受损。研究显示了在记忆和执行功能领域随着年龄增长会发生哪些生理变化,这对于正常衰老与老年人常见脑部疾病早期阶段的鉴别诊断具有重要的临床意义。
