BACKGROUND Enhanced ability to reliably identify risk factors for suicidal behavior permits more focused decisions concerning treatment interventions and support services, with potential reduction in lives lost to suicide. METHODS This study followed 980 patients at high risk for suicide in a multicenter prospective study for 2 years after randomization(More)
OBJECTIVE Positron emission tomography (PET) was used to compare cerebral metabolic patterns in schizophrenic subjects with predominantly negative symptoms (alogia, affective flattening, avolition, and attentional impairment) and in those with predominantly positive symptoms. METHOD Fourteen right-handed male subjects with DSM-IV schizophrenia were(More)
BACKGROUND Approximately 50% of patients with schizophrenia or schizoaffective disorder attempt suicide, and approximately 10% die of suicide. Study results suggest that clozapine therapy significantly reduces suicidal behavior in these patients. METHODS A multicenter, randomized, international, 2-year study comparing the risk for suicidal behavior in(More)
OBJECTIVES To investigate the relationship between activities of daily living (ADL) impairment and Alzheimer's disease (AD) severity in mild to moderately severe AD patients receiving the cholinesterase (ChE) inhibitor rivastigmine. METHODS ADLs were evaluated using the Progressive Deterioration Scale (PDS). Disease severity was assessed with the Global(More)
Goals of the study included evaluating the long-term efficacy of rivastigmine in Alzheimer's disease (AD) patient categories stratified by baseline dementia severity, and post hoc investigation of particular benefits of early initiation of rivastigmine treatment in moderately severe AD. Both rivastigmine-treated groups (originally randomized to 1-4 or 6-12(More)
On September 18, 2007, a collaborative session between the International Society for CNS Clinical Trials and Methodology and the International Society for CNS Drug Development was held in Brussels, Belgium. Both groups, with membership from industry, academia, and governmental and nongovernmental agencies, have been formed to address scientific, clinical,(More)
BACKGROUND Almost 50% of schizophrenic persons attempt suicide at some time in their lives and 9-13% of patients ultimately commit suicide. While numerous studies have elucidated the relationship between psychiatric symptomatology and neurocognition in patients with schizophrenia, this is the first report, to our knowledge, to investigate the relationship(More)
BACKGROUND The InterSePT Scale for Suicidal Thinking (ISST) is a 12-item instrument for the assessment of current suicidal ideation in patients with schizophrenia and schizoaffective disorders. We report the psychometric characteristics of this new scale based on two studies. METHOD In Study 1, 22 inpatients with schizophrenia and schizoaffective(More)
OBJECTIVE BL-1020 is a γ-aminobutyric acid (GABA)-enhanced antipsychotic that combines dopamine antagonism with GABA agonist activity. On the basis of animal models, we tested the hypotheses that BL-1020 would be effective in ameliorating both psychotic symptoms and cognitive impairments, with a favorable safety profile in acutely ill schizophrenia(More)
BACKGROUND BL-1020, a novel gamma aminobutyric acid (GABA) ester of perphenazine, is a new oral antipsychotic with a strong affinity for dopamine and serotonin receptors. Unlike first- and second-generation antipsychotics, it has agonist activity at GABA(A). OBJECTIVE This is the first study to examine tolerability and safety of BL-1020 in schizophrenia.(More)
