Abstract The Alzheimer's disease (AD) is characterized by ²-amyloid (²A) and hyperphosphorilated Tau protein deposition in the nervous tissue, which compromises cognitive functions, with repercussions over cognition and behavior. One of the physiopathological hypothesis to explain this injury involves the increase in the oxidative stress and in the following decrease of telomere length. Telomeres are considered a "biological clock" of cells in this tissue, and its shortening associates with precocious senescence of both neuron and glial cells. Positive evidences in the use of lithium in the AD treatment have been shown by various studies. It is believed that various cell paths are modified by this metal. Among them, one which is responsible for decreasing reactive oxygen species (ROS) production, leading to a possible path to reduce oxidative stress over cells, and, therefore, maintaining their physiologic functions.
