Diabetes mellitus (DM) is the group of metabolic disorders that has as a common characteristic the disregulation of blood glucose levels, invariably leading to hyperglycemia. This disease has become the most frequent in the adult population, mainly in developing countries, causing several serious consequences such as cardiovascular and renal diseases, factors responsible for a high mortality rate of the individuals affected. In addition that consequences, which are better investigated and described in the literature, other types of complications are observed. Clinical and experimental studies demonstrate that both type 1 and type 2 diabetes mellitus may contribute to the development of cognitive deficits and dementias. However, the mechanisms that lead to such disorders are not yet fully understood. A study using the non-selective non-steroidal anti-inflammatory, indomethacin, has shown that aspects related to impaired neuronal plasticity in diabetes can be reversed, demonstrating that these disorders may be modulated by neuroinflammatory changes. The aim of the present study was to evaluate the influence of chronic treatment with indomethacin on memory and learning in a murine model of type 1 diabetes mellitus (T1DM). Using the open field test, Y-maze test and Morris water maze test we investigated the indomethacin effects on behaviors changes after aloxan inducing T1DM. Indomethacin significantly decrease related behaviors to the anxious state in Open field test. This treatment also reversed space work memory deficits in the Y-maze test, and learning and spatial memory deficits in the Morris Water Maze. Thus, it can be concluded that chronic treatment with indomethacin has beneficial effects on the cognition of mice submitted to type 1 diabetes mellitus.
