摘要翻译：
本文在Fokker-Planck方程的基础上，给出了最近[Cressoni et al.，Phys.Rev.Lett.98，070603(2007)和Sch\“Utz and Trimper，Phys.Rev.E70，045101(2004)]为Alzheimer行为和相关现象而引入的具有记忆的随机游动的解析公式，并给出了精确解。为此导出的时滞微分方程的解可以产生对数周期振荡，与以前发表的计算机模拟结果相当吻合。在此基础上，还构造了几个方向的推广。

英文摘要：
An analytic formulation of memory-possessing random walks introduced recently [Cressoni et al., Phys. Rev. Lett. 98, 070603 (2007) and Sch\"utz and Trimper, Phys. Rev. E 70, 045101 (2004)] for Alzheimer behavior and related phenomena is provided along with exact solutions on the basis of Fokker-Planck equations. The solution of a delay-differential equation derived for the purpose is shown to produce log-periodic oscillations and to coincide rather accurately with previously published computer simulation results. Generalizations along several directions are also constructed on the basis of the formalism.
