Preview

rTMS has an increasing role as a useful investigational tool for probing neuronal circuitry in a variety of neuropsychiatric disorders. However its therapeutic value is at present less certain. The anti-depressant efficacy of rTMS has now been investigated for over 15 years and despite initial early enthusiasm there is still not clear evidence for its usefulness as a treatment in depression, reflected in the recent FDA and NICE decisions. Further research is required to identify specific brain regions in specific conditions that may be appropriate targets for treatment with rTMS, allowing tailoring of treatments for individual patients. The recent development of neuronavigational techniques using MRI imaging should aid treatment site localization. Other future research should be directed at establishing optimal rTMS parameters, e.g. the intensity, frequency and number of treatments.
