We use auditory verbal hallucinations (AVH) to illustrate the challenges in defining and assessing target engagement in the context of transcranial direct current stimulation (tDCS) for psychiatric disorders. We defined the target network as the cluster of regions of interest (ROIs) that are consistently implicated in AVH based on the conjunction of multimodal meta-analytic neuroimaging data. These were prescribed in the New York Head (a population derived model) and head models of four single individuals. We appraised two potential measures of target engagement, tDCS-induced peak electric field strength and tDCS-modulated volume defined as the percentage of the volume of the …

It can be hard getting help for someone with mental illness, but almost impossible when that person doesn't think they are sick. At at least half of people with schizophrenia, for example, insist that the voices they hear are real. People who do not know they are ill often refuse therapy and medication -- and their symptoms can spiral out of control. Doctors call this lack of awareness anosognosia. Neurologists are trying to discover what causes this baffling condition--and how to treat it.
