Law enforcement officers, and the criminal justice system more generally, encounter psychotic individuals at a high rate due to legal infractions committed consciously or resulting from symptoms of the disorder. The purpose of this study was to determine whether a broad range of biopsychosocial symptoms predicted more severe legal problems. In addition, we studied whether a biopsychosocial mode...

Here, we report psychotic symptoms together with a right cerebellopontine-angle lesion. A37-year-old female patient presented with a trigeminal Schwannoma occupying the right cerebellopontine angle. Her psychotic symptoms included auditory hallucinations and delusions of persecution. T1- and T2-weighted images on magnetic resonance imaging (MRI) revealed hyperintense and hypointense areas in th...

BACKGROUND Psychosis is rare in untreated patients with Parkinson's disease (PD) but the prevalence rises to 40% during dopaminergic treatment. So far, no systematic comparison of the psychogenic potential of different dopaminergic drugs had been performed. METHODS Eighty PD patients with psychotic episodes were compared to an age-matched control group of PD patients without psychotic episode...

BACKGROUND The aim of the TAILOR trial is to investigate the effect of closely monitored tapering/discontinuation versus maintenance therapy with antipsychotic medication in patients with newly diagnosed schizophrenia or persistent delusional disorder and with minimum 3 months' remission of psychotic symptoms. METHODS AND DESIGN Two hundred and fifty patients will be included from the psychia...

OBJECTIVE It is not clear whether the prevalence of psychosis increases with age. We studied the age-specific prevalence of psychotic symptoms in older people in Western Europe. METHODS Older people without dementia (age 65-104 years, N = 8762) from the western part of Europe in the EURODEP concerted action took part in psychiatric examinations. RESULTS In total, 2.4% of the men and 2.9% of...

OBJECTIVE Large epidemiological surveys conducted in the developed world have found rates of psychotic symptoms in the general population to be as high as 10-28%. However, there are few data available from developing countries, including African countries, on the prevalence and correlates of psychotic symptoms. This study investigates the prevalence and correlates of psychotic symptoms (ie hall...

BACKGROUND Non-clinical psychotic symptoms appear common in children, but it is possible that a proportion of reported symptoms result from misinterpretation. There is a well-established association between pre-morbid low IQ score and schizophrenia. Psychosis-like symptoms in children may also be a risk factor for psychotic disorder but their relationship with IQ is unclear. AIMS To investiga...

OBJECTIVE To estimate the lifetime prevalence of 12 DSM-IV disorders with psychotic symptoms in a general population survey. METHOD Addresses were contacted in a multistage clustered area probability sampling frame of administrative neighbourhoods and households, covering 9 districts and 302 neighbourhoods in the Izmir metropolitan area between November 2007 and October 2008. One household me...

BACKGROUND There is emerging evidence that antidepressants may be effective in preventing patients with non-specific and psychotic-like prodromal symptoms, defined as patients at ultra-high risk (UHR) of psychotic disorder, from transitioning to psychosis. However, the mechanism of such an effect is still unknown. METHODS We report the case of a 19-year-old Japanese man determined to be at UH...
