This paper describes a study of brief psychotic and depressive symptoms in inpatients with narrowly defined Borderline Personality Disorder. Almost al...

BACKGROUND Psychoactive substance abuse, which includes abuse of alcohol and street drugs, is common among first-episode psychosis patients, but the prevalence of cannabis abuse is particularly high. However, there have been very few reported studies concerning the occurrence of psychoactive substance abuse among first-episode psychotic individuals using standard toxicological testing. We study...

Patients with psychotic disorders appear to exhibit greater impulsivity-related behaviors relative to healthy controls. However, the neural underpinning of this impulsivity remains uncertain. Furthermore, it remains unclear how impulsivity might differ or be conserved between psychotic disorder diagnoses in mechanism and manifestation. In this study, self-reported impulsivity, measured by Barra...

UNLABELLED The relevance of negative symptoms across the diagnostic spectrum of the psychoses remains uncertain. The purpose of this study was to report on prevalence of item and subscale level negative symptoms across the first episode psychosis (FEP) diagnostic spectrum in an epidemiological sample, and to ascertain whether items and subscales were more prevalent in a schizophrenia spectrum d...

Although history has shown that the onset of psychotic disorders typically begins in early adulthood, recent research has identified a specific population of children and adolescents who develop psychotic disorders at a young age. Children and adolescents who develop psychotic disorders typically have a more complex course and worse prognosis than adult onset. For this reason, early interventio...

A comparative analysis of psychotic versus nonpsychotic stalking is presented. Archival files of 25 forensic subjects whose alleged criminal offenses met a legal definition of stalking behavior were studied for demographic characteristics, stalking dynamics, psychosocial history, and current psychological variables. Although nearly one-third of all subjects had an Axis I psychotic disorder and ...

The presence of psychotic features in the course of a depressive disorder is known to increase the risk for bipolarity, but the early identification of such cases remains challenging in clinical practice. In the present study, we evaluated the diagnostic performance of a neuroanatomical pattern classification method in the discrimination between psychotic major depressive disorder (MDD), bipola...

BACKGROUND Cancer is commonly perceived as life-threatening and universally stressful; however, brief psychotic disorder, which occurs in response to extremely stressful events, has not been reported. CASE PRESENTATION A 63-year-old woman, who was diagnosed as having pancreatic cancer with liver metastasis, became unresponsive with very little reaction to verbal contact after sequential life-...
