Objective: This study investigated olfactory function disorder in Canadian potential AD patients through measuring the detection threshold and recognition threshold, of the potential AD patients and the matched controls by Five Odorants Test; and evaluated whether the senile plaques, neurofibrillary tangles and neuropil threads , which were the typical pathological changes of AD, presented in the olfactory mucosa of potential AD patients.

老年性痴呆中有75%为阿尔茨海默病(Alzheimer's disease， AD)，AD 是一种神经细胞退行性疾病，原因不明，临床以进行性记忆丧失和后天获得的知识丧失，病程逐渐发展直至完全丧失生活能力为特征。其病因是多原性的。尽管AD 的描述已达90 年之久，但要在早期检出此病仍是一个难题，所以，改进其临床诊断程序、途径非常重要。当今广泛用于AD 诊断的诸多标准中均未明确提及嗅觉的改变，然而众多国外文献资料表明，几乎所有的AD 患者发病早期甚至在临床前期即表现嗅觉识别阈的改变，可见对此深入研究有助于AD 患者的早发现、早诊断。

This paper firstly analyses the limitations of traditional potential field methods in dynamic environment,and based on this analysis,the traditional potential field is improved by introducing the concept of velocity potential field .
