[Minimally invasive brain stimulation for unipolar depression].

BACKGROUND

Unipolar depression is one of the most prevalent psychiatric disorders and has a high impact at individual and societal level. Commonly used treatments such as antidepressants and psychotherapy are often not effective.

AIM

To determine the efficacy of repetitive transcranial magnetic stimulation (rTMS) and direct current stimulation (tDCS) as minimally invasive forms of treatment for unipolar depression.

METHOD

We searched the literature.

RESULTS

rTMS is effective in treating unipolar depression and is comparable to existing forms of medication and behavioural therapy. The effects of tDCS are promising, but more research is needed.

CONCLUSION

rTMS is a useful addition to the existing arsenal of treatment for unipolar depression.
