“The review represents the analysis of works about role of endogenous cannabinoid (EC) system in the neuro- degenerate diseases (ND), in which the cellular death and disturbances of neuronal functions of the hippo- campus, neocortex and striatum are observed. Here, the diseases.ofAlzheimer, of Parkinson, of Hangtington, and the temporal lobe epilepsy are considered. In recent years the fundamental role of EC system in regu- lation of neuroexcitability, energy metabolism, inflammatory and many other processes has been opened in ND pathogenesis. It points to possibility of development of therapeutic approaches which use the prepara- tions for activation of EC system. In the review various mechanisms of cellular survival and their reparations provided to EC system during action of pathological factors are stated.”
