CASE HISTORY Mr. R was a 19-year-old, single, unemployed, homeless Hispanic male with a history of Tourette’s syndrome (TS), obsessivecompulsive disorder (OCD), attention-deficit/hyperactivity disorder (ADHD), and posttraumatic stress disorder. In addition, he suffered from suicidal ideation, self-injurious behavior (superficial cutting and head banging), anxiety, depression, and anger outburst...

Over the last 20 years, SPECT and PET, along with CT and MRI have been the main methodologies used in studies investigating psychiatric disorders. The structural alterations in patients’ brains found by CT and MRI are usually quite subtle, while those found by the nuclear imaging modalities (PET and SPECT) are more pronounced. Partly for this reason, the latter methods have led to discoveries i...

Introduction: The findings of the quantitative EEG power-spectral studies in obsessive-compulsive disorder (OCD) have so far been mostly inconsistent. Moreover, none of the studies has been a high resolution one. Aim: The aim of the study was to examine the band power of delta, theta, alpha, beta1 and beta2 bands with high resolution EEG data in patients with obsessivecompulsive disorder and co...

Objective: The present study describes the process of translation into Brazilian Portuguese and the cross-cultural adaptation of the Obsessive-Compulsive Inventory and the Obsessive-Compulsive Inventory-Revised scales. The Obsessive-Compulsive Inventory was developed with the purpose of measuring the intensity of the various symptoms that characterize the obsessive-compulsive disorder, assessin...

223 Useful animal models for the investigation of autoimmune disorders that involve the brain are essential, especially in children in whom access to the CNS is limited. The paucity of such models can hinder an understanding of causation, pathogenic mechanisms, and treatments. This is particularly true when one is investigating postulated antibody-mediated disorders in which evidence supporting...

Introduction The localization of cognitive domains can be achieved by functional imaging modalities such as fMRI, PET and MEG. It was recently shown that voxel-wise correlation between high resolution quantitative structural MRI (e.g. diffusion tensor imaging indices, DTI) and various behavioral measures allows brain localization of cognitive performance. This approach hypothesizes that inter-s...

Objective: This study investigates obsessive-compulsive disorder patients in terms of strategic planning and its association with specific obsessivecompulsive symptom dimensions. Method: We evaluated 32 obsessivecompulsive disorder patients. Strategic planning was assessed by the ReyOsterrieth Complex Figure Test, and the obsessive-compulsive dimensions were assessed by the Dimensional Yale-Bro...
