Addressing psychiatric education in Latin America: challenges and opportunities.

This article is about the psychiatric educational components in the field of psychiatry. Currently the training and educational objectives focus on five major areas: undergraduate education (medical students); graduate education (psychiatric residents); psychiatric education for primary care physicians, as well as physicians in other medical specializations (psychosomatic training); public health and public education at large, and patient and family education, and the promotion of 'mental health' at a community level. Given the strong globalization process observed in all regions of the world in the past two or three decades, it is very important for Latin America to constantly review and update its psychiatric and behavioural sciences curriculum across all medical institutions and universities of the continent.

Asymmetrical contribution of brain structures to treatment-resistant depression as illustrated by effects of right subgenual cingulum stimulation.

Major depressive disorder is one of the most common psychiatric disorders, with a worldwide lifetime prevalence rate of 10%-20% in women and a slightly lower rate in men. While many patients are successfully treated using established therapeutic strategies, a significant percentage of patients fail to respond. This report describes the successful recovery of a previously treatment-resistant patient following right unilateral deep brain stimulation of Brodmann's area 25.

Emotion processing and theory of mind in schizophrenia patients and their unaffected first-degree relatives.

Previous studies have suggested that social cognition is affected in individuals with schizophrenia. The purpose of this study was to explore to what extent social cognition deficits are shared by unaffected first-degree relatives, and the nature of the relationship between performance in different paradigms of social cognition. 20 Schizophrenia patients (7 females, 31+/-10 years), 20 healthy age- and gender-matched individuals, 20 unaffected first-degree relatives of the schizophrenia patients (11 females, 50+/-20 years), and 20 healthy individuals matched for age and gender were recruited.

Decision-making in Parkinson's disease patients with and without pathological gambling.

Background And Purpose: Pathological gambling (PG) in Parkinson's disease (PD) is a frequent impulse control disorder associated mainly with dopamine replacement therapy. As impairments in decision-making were described independently in PG and PD, the objective of this study was to assess decision-making processes in PD patients with and without PG.

Methods: Seven PD patients with PG and 13 age, sex, education and disease severity matched PD patients without gambling behavior were enrolled in the study.

Heart rate variability response to mental arithmetic stress is abnormal in first-degree relatives of individuals with schizophrenia.

Background: Schizophrenia patients exhibit an abnormal autonomic response to mental stress. We sought to determine the cardiac autonomic response to mental arithmetic stress in their unaffected first-degree relatives.

Methods: Heart rate variability (HRV) analysis was performed on recordings obtained before, during, and after a standard mental arithmetic task to induce mental stress.
