对认知障碍认识的常见误区

Common misunderstandings of cognitive impairment

认知障碍是临床常见问题,但是临床医生对一些概念的理解还存在误区,将痴呆定义为智能障碍综合征,单纯依据神经心理量表诊断认知障碍,认为轻度认知障碍是痴呆前期,失语患者不能诊断痴呆,卒中后认知障碍是卒中后六个月发生等,讨论和澄清这些问题,对于正确理解认知障碍的诊断,指导临床工作有重要意义。

Cognitive impairment is a common clinical presentation,however,clinicians still have some misunderstandings about some related concepts.Such as,dementia is defined as mental disorder syndrome,cognitive impairment is diagnosed solely on basis of neuropsychological scale,mild cognitive impairment is pre-dementia condition,patients with aphasia cannot be diagnosed as dementia,and post-stroke cognitive impairment is the cognition disorder that occurs six months after stroke.Discussing and clarifying these issues are important for the diagnosis of cognitive impairment and for guiding clinical practice.
