ModifiedElectraconvulsiveTherapy (MECT), which began in the early 1960s and is also known as spasm-free or twitch-free electroconvulsive therapy, was developed after ECT (electroconvulsive therapy, applied in 1938, is the stimulation of the head with a certain amount of electric current to cause loss of consciousness and generalized convulsive seizures in patients to It is an ancient and very effective method of treating mental disorders.) The treatment is based on a modified version of the method. Before treatment, an appropriate amount of muscle relaxant is injected, and then a certain amount of electric current is used to stimulate the brain to cause loss of consciousness, thus achieving no convulsive seizures and treating psychiatric disorders. Indications: (1) Patients with severe depression, obvious self-blame, self-guilt, self-injury, suicide attempts and behavior. (2) Excitement, agitation, impulsivity, injury and destruction of objects. (3) Refusal of food, disobedience, and nervous rigidity. (4) Those who have failed to respond to psychotropic medication or are intolerant to medication. Generally, three to four treatments can eliminate the severe negative perceptions and symptoms of rigidity. The literature shows that MECT is effective in 90% of patients with major depression, usually after 6 to 8 treatments; in 90% of patients with mania, usually after 8 to 10 treatments; and in 75% of patients with acute symptoms of schizophrenia.
