Background:
Transcranial magnetic stimulation (TMS) has been suggested for the treatment of a variety of CNS disorders including depression and mania.
Methods:
Nine bipolar (I) in-patients diagnosed with mania were treated with right prefrontal rapid TMS in an open and prospective study. Eight of nine patients received TMS as add-on treatment to an insufficient or only partially effective drug therapy.
Results:
During the 4 weeks of TMS treatment a sustained reduction of manic symptoms as measured by the Bech-Rafaelsen mania scale (BRMAS) was observed in all patients.
Limitations:
Due to the open and add-on design of the study, a clear causal relationship between TMS treatment and reduction of manic symptoms cannot be established.
Conclusions:
Our data suggest that right prefrontal rapid TMS is safe and efficacious in the add-on treatment of bipolar mania showing laterality opposed to the proposed effect of rapid TMS in depression.
