[Transcranial magnetic stimulation in psychiatric therapy]

Transcranial magnetic stimulation (TMS) is one of new techniques of the physical treatment in psychiatry. Its advantage is painlessness, so as lack of invasiveness and evoking a convulsive effect. The technique of TMS was introduced into the clinical practice in 1985--originally as a diagnostic method in neurology. Later TMS became a valuable tool in the basic research in neurophysiology and neuropsychology, so as in clinical examinations. In 1994 the first papers on TMS application in therapy of depression and schizophrenia were published. The research on the therapeutic TMS effectiveness encounters certain problems and restrictions: difficulties in determining a place of the stimulation, lack of the possibility of the selection of optimal parameters for the stimulation, problem in guarantying optimal conditions for the double-blind study, etc. During the last two decades TMS was applied in therapy of mood disorders and psychoses more on the principle of consuetude, than confirmations of the evident effectiveness. However recently a group of European experts presented the study, in which they regarded TMS as the effective method in therapy of depression and schizophrenia--presenting conditions to the optimal stimulation.
