The effects of dementia etiology and severity on the confrontation naming ability of individuals with Alzheimer's, Huntington's, and Parkinson's diseases and multi-infarct dementia are investigated. Although naming impairment is reported as a consequence of dementing illness, confrontation naming is not found to be significantly impaired in mildly involved patients. Further, although moderate Huntington's and Parkinson's patients made more naming errors than normals, only moderate Alzheimer's disease patients are found to be significantly different. Regardless of etiology, most misnamings are found to be semantically related or semantically and visually related to the stimulus. Results challenge the theory that misnamings of dementia patients result primarily from misperception.
研究了痴呆病因和严重程度对患有阿尔茨海默病、亨廷顿病、帕金森病和多发梗死性痴呆患者的对物命名能力的影响。尽管有报道称命名障碍是痴呆症的后果，但在轻度受累患者中未发现对物命名有明显受损。此外，尽管中度亨廷顿病和帕金森病患者比正常人犯更多的命名错误，但仅发现中度阿尔茨海默病患者有显著差异。无论病因如何，大多数错误命名在语义上与刺激物相关，或在语义和视觉上与刺激物相关。研究结果对痴呆症患者的错误命名主要源于错误感知这一理论提出了挑战。
