Psychiatric medical literature cites the importance of etiological factors in the arterial hypertension break-out, showing that the tiredness, the psychic traumatism and the negative emotions go to the diminution of cortex’s functional capacity, with hypothalamic functional perturbations, which induce a hyper excitability and an important instability of vessel-regulatory function. The main cause seems to be the emotional tension which acts through the mediation of vegetative nervous system on vaso-motorial innervation. The personality of some individuals with arterial hypertension is calm on the outside, while on the inside it has an aggressive and hostile attitude, inducing a permanent condition of tension in organism. The psychological modifications of cardiovascular system within the mental stress (modifications often reversible), as well as the psychopathological perturbations quasiconstantly present exert a negative influence on the cortex, determining a series of symptoms grouped into a neuroastheniform syndrome, which leads to dispositional modifications of the patient.
