Effects of Transcranial Magnetic Stimulation on the Hypothalamic-Pituitary Axis in Depression: Results of a Pilot Study.

Some studies have reported that repetitive transcranial magnetic stimulation (rTMS) applied to the dorsolateral prefrontal cortex (DLPFC) is able to induce changes in the hypothalamic-pituitary axis in subjects with major depression. The causes of these neuroendocrine effects are unknown and deserve to be studied. The authors monitored neuroendocrine hormones in 15 subjects with major depression treated by 1-Hz rTMS on the right DLPFC and explored a correlation with mood improvement.
