An apparatus and a related method for the deep brain stimulation have been invented wherein the parameters of the stimulation supplied at the human nervous system level are adjusted and optimized continuously by the analysis of the bioelectric signals coming from the tissue adjacent the stimulation electrode itself, adapting the therapy continuously and in line to the patient's clinical state. The apparatus is constituted at least by an electro-catheter ( 1 ) implantable in a patient's brain and equipped with four contacts ( 4, 5, 6, 7 ). Then, there is at least a stimulation module ( 9 ) which generates the stimulating signal ( 15 ) sent to the electro-catheter ( 1 ) and in particular to one of the contacts thereof ( 6 ). The electro-catheter ( 1 ) contemporarily sends a signal characterizing the brain activity coming from the tissue involved by the stimulating signal ( 15 ) to an acquisition module ( 8 ). The characterizing signal is used to determine the feedback of the stimulation parameters ( 15 ) and, consequently, to adapt the therapy continuously to the patient's clinical state.
