This book, which covers Visions and hallucinations, explains what causes them and summarises how many hallucinations have been caused by each event or activity. It also provides specific help with questions people have asked us, such as ‘Is my medication giving me hallucinations?’.

A description of the experience

J ECT. 2011 Sep;27(3):256-8. doi: 10.1097/YCT.0b013e3182012b89. Hypomania induction in a patient with bipolar II disorder by transcranial direct current stimulation (tDCS). Gálvez V, Alonzo A, Martin D, Mitchell PB, Sachdev P, Loo CK. School of Psychiatry, University of New South Wales, Sydney, Australia.

OBJECTIVES: To report a case of hypomania induced by transcranial direct current stimulation (tDCS) given with an extracephalic reference electrode. Transcranial direct current stimulation is a noninvasive brain stimulation technique in which a weak current is applied through the scalp to produce changes in neuronal excitability in the underlying cerebral tissue. Recent clinical trials have shown promising results with left anodal prefrontal tDCS in treating depression. When the reference cathodal electrode in tDCS is moved from the cranium to an extracephalic position, larger areas of both cerebral hemispheres are stimulated, with potential implications for both efficacy and safety.

METHODS: We report the case of a 33-year-old female with bipolar II disorder, on mood stabilizer medication, who had previously participated in a clinical trial of tDCS given with a bifrontal electrode montage for the treatment of major depression without incident, but became hypomanic when she received a later course of tDCS given with a frontoextracephalic configuration. Factors contributing to the development of hypomania in the second course of tDCS are examined.

RESULTS: No substantial differences were found in the patient's clinical presentation between the 2 tDCS courses to explain the emergence of hypomania only after the second course. The different montage used in the second course appeared to be the main contributory factor in the induction of hypomania.

CONCLUSIONS: The reported case suggests that frontoextracephalic tDCS has antidepressant properties and the potential to induce hypomanic symptoms. In particular, it raises the question of whether frontoextracephalic tDCS requires additional precautions when administered to bipolar patients compared to bifrontal tDCS.
