Praxia represents the totality of the gestures and movements necessary to perform complex voluntary actions in order to accomplish a goal. Praxia has two aspects: on the one hand, intentional activity and on the other hand a mnestic activity based on memorizing the succession over time and space of the various movements to be performed in order to accomplish the intentional action. Programming the fulfillment of a voluntary action in order to achieve a well-defined purpose proceeds gradually, at different successive levels. The first level is the conceptual one. The person aims to achieve a certain purpose, sets the purpose of the voluntary motor action. The second level is that of the kinetic formulation of action, gesture. The individual disintegrates from the mnesic stock of all kinetic formulas he has learned during his ontogenetic development those formulas that are most appropriate to achieve the proposed action. The third level includes central and peripheral motor innervation, pyramidal, extrapyramidal, cerebellar and medullary motoring ways, which are the peripheral performers of the voluntary action. At this level the harmonious interactions between the different muscles involved in the movements are established, as well as the harmonious innervation of the synergic muscles, fixators, agonists and antagonists. The study comprises 5 patients admitted in the clinic of psychiatry in Constan�a, who presented oro-facial-lingual apraxia, apraxic dysphasia and aphasia, appeared in various evolutionary phases of intracranial neoformative processes. Apraxia was due to the increase of the kinetic engraving threshold, to the laughter they are sequenced by the logic of gesture efficiency; the often repeated, deeply fixed, kinetic engraves are automated in time.The co-ordination needed to perform a gestional motor task in order to accomplish a determined action has significant psychological implications.
