Subcortical Structures in Demented Schizophrenia Patients: A Comparative Study.

There are few studies on dementia and schizophrenia in older patients looking for structural differences. This paper aims to describe relation between cognitive performance and brain volumes in older schizophrenia patients. Twenty schizophrenic outpatients -10 without-dementia (SND), 10 with dementia (SD)- and fifteen healthy individuals -as the control group (CG)-, older than 50, were selected.

Disruption of the right temporoparietal junction with transcranial magnetic stimulation reduces the role of beliefs in moral judgments.

When we judge an action as morally right or wrong, we rely on our capacity to infer the actor's mental states (e.g., beliefs, intentions).

One session of high frequency repetitive transcranial magnetic stimulation (rTMS) to the right prefrontal cortex transiently reduces cocaine craving.

Background: Cocaine dependence is a public health problem affecting 2 million individuals in USA. Craving is a predictor of subsequent cocaine use and is related to changes in brain activity in networks involving the prefrontal cortex.

Methods: We investigated the efficacy of one session of high frequency repetitive transcranial magnetic stimulation (rTMS) to reduce craving in cocaine addicted subjects.
