ESTER

According to various estimates, from 20% to 30% of people with depression do not respond to traditional methods of treatment (drug therapy, psychotherapy, light therapy, etc.), therefore, in these cases, more radical methods are used. First of all, this is electroconvulsive therapy (ECT), which began to be used in the thirties of the twentieth century.
  For many diseases, ECT remains the most effective and safe therapy. To date, according to foreign psychiatrists, ECT is ideally suited 80% of patients. It is widely used to treat mental, narcological and neurological diseases.
   
The device is intended for electroconvulsive (electroconvulsive) therapy in a number of mental, narcological and neurological diseases with a series of unipolar rectangular current pulses passing through the corresponding brain structures and affecting its neurons. An electrical impulse that causes a therapeutic epileptiform seizure in the brain stimulates the hypothalamus and structures of the limbic system, increasing the secretion of peptides (for example, the hypothetical eutimesin peptide) involved in mood regulation. In this case, a fairly rapid decrease in the vegetative manifestations of depression occurs.
  The device allows you applying a series of unipolar rectangular current pulses to the brain structures using special electrodes installed monolaterally, bilaterally (bifrontally) on the patient’s head.
  It can be used in psychiatric clinics and hospitals.
