 Panic disorder and transcranial magnetic stimulation     García-Toro M, Salva Coll J, Crespí Font M, Andrés Tauler J, Aguirre Orue I, Bosch Calero C.

[email protected] Transcranial magnetic stimulation (TMS) has been tried in some Anxiety Disorders (Obsessive-compulsive disorder and Posttraumatic Stress Disorder) with different results. We present a pilot study including three Panic Disorder patients. The subjects who were enrolled had a history of the disease for at least 1 year and they had unsuccessfully followed psychotherapy and pharmacological treatment. The patients received 10 sessions during two weeks; each session lasted 30 trains of 60 seconds at a frequency of 1 Hz, on the right dorsolateral prefrontal cortex, at 110% of the motor threshold. All three patients experienced a modest and partial symptom improvement that did not seemed to be clinically relevant. Two patients accepted to participate in a TMS second phase, where the previous stimulation parameters were alternated with an application of 30 trains of 20 Hz during 2 seconds on the left prefrontal cortex. This alternate application of high and low frequency TMS in each session was also well tolerated, but failed to produce additional improvement. In addition to presenting these three cases, we emphasize some features concerning the neurobiological basis of the anxiety disorders and we connect them to the previously described TMS neurophysiological actions in order to justify further investigation.   Fonte: Actas Esp Psiquiatr. 2002 Jul-Aug;30(4):
