: One of the fundamental prerequisites of the successful schizophrenia treatment is represented by an adequately significant impact on the negative symptoms of schizophrenia. Since the present pharmacotherapy has probably reached its limit in this area, there is a logical effort to utilize other, non-pharmacological methods. One of the most promising supplements that has been for a long time verified in the clinical practice is rTMS. Most of the studies have arrived at the conclusion that rTMS is an efficient method in the treatment of negative symptoms of schizophrenia. A valuable contribution to the assessment of the rTMS application in the treatment of negative symptoms is represented by meta-analyses. The meta-analyses indicate that the effect is mild to moderate (d=0.43 to 0.68). To sum it up, there will be higher probability of the rTMS effect on negative symptoms if 10 Hz stimulating frequency and a longer stimulation period in the extent at least three, ideally four to six weeks is used.
