自发沟通的手臂手势进行了评估老年患者可能阿尔茨海默病(AD)和健康对照(NC)。基于语音和手势产生于共同的语义概念表征的概念,预期与AD中的语义记忆障碍相关的定性相似的语言和手势交流障碍。尽管相同的数量和速率的手势,AD和NC组产生了质的不同类型的手势。AD患者产生了更多的模糊手势,更少的手势是指隐喻,而不是具体的内容,更少的概念复杂的双手手势。手势清晰度受损与语言/概念障碍的严重程度和干扰生产的哑剧动作的测试,idetherelimb肢体失用症。结果是一致的假设,即中央语义概念障碍的基础上类似的语言和手势交流障碍的AD。
Spontaneous communicative hand-arm gestures were evaluated in elderly patients with probable Alzheimer's disease (AD) and healthy controls (NC). Based on the notion that speech and gestures arise from common semantic-conceptual representations, qualitatively similar linguistic and gestural communicative impairments were expected in association with semantic memory impairment in AD. Despite equal quantity and rate of gesturing, AD and NC groups produced qualitatively different types of gestures. Patients with AD produced proportionately more referentially ambiguous gestures, fewer gestures referring to metaphoric as opposed to concrete contents, and fewer conceptually complex bimanual gestures. Impaired gestural clarity correlated with severity of linguistic/conceptual impairments and disturbed production of pantomimic movements on a test of ideomotor limb apraxia. Results are consistent with the hypothesis that a central semantic-conceptual disorder underlies the similar linguistic and gestural communication impairments in AD.
