Nootropic drugs and aging.Acta Psychiatr Belg. 1983 Jul-Aug; 83(4):349-58.AP
Nootropics are drugs which ameliorate the functional "plasticity" of the central nervous system. The nootropic drug acts at the telencephalic level through a series of bioenergetic, hemorheological, microcirculatory and neurochemical mechanisms. As to this, recent data show a facilitation by piracetam, of the efficiency of the central cholinergic system.
