阿尔茨海默病所致痴呆

定义

阿尔茨海默病所致痴呆是最常见的痴呆形式。起病隐匿，通常以记忆障碍为初始主诉症状。其特征性病程是认知功能从以前水平缓慢稳定地下降，随病情发展，出现其他认知领域（如执行功能、注意力、语言、社会认知和判断、精神运动速度、视觉感知或视觉空间能力）的损害。阿尔茨海默病所致痴呆在发病初期可能伴有精神和行为症状，如情绪低落和冷漠，后期可能伴有精神症状、易激惹、攻击性、意识模糊、步态和行动异常以及癫痫发作。基因检测阳性、家族史和认知能力逐渐下降都提示患有阿尔茨海默病所致痴呆。

Dementia due to Alzheimer disease is the most common form of dementia. Onset is insidious with memory impairment typically reported as the initial presenting complaint. The characteristic course is a slow but steady decline from a previous level of cognitive functioning with impairment in additional cognitive domains (such as executive functions, attention, language, social cognition and judgment, psychomotor speed, visuoperceptual or visuospatial abilities) emerging with disease progression. Dementia due to Alzheimer disease may be accompanied by mental and behavioural symptoms such as depressed mood and apathy in the initial stages of the disease and may be accompanied by psychotic symptoms, irritability, aggression, confusion, abnormalities of gait and mobility, and seizures at later stages. Positive genetic testing, family history and gradual cognitive decline are suggestive of Dementia due to Alzheimer disease.
