Citicoline, also CDP-choline, is a molecule with psychostimulating and nootropic activity, that is, it is able to increase the cognitive abilities of the individual. Citicoline carries out its activity at the level of alterations in neuronal metabolism, at the level of neurotransmission and at the level of haemodynamic disorders; therefore, it induces a better general level on cerebral metabolism, favors the use of oxygen in the brain and normalizes the threshold values of both the awakening reactions and the neuro-myoelectric transmission.
