Switching a combination of first- and second-generation antipsychotic polypharmacy to antipsychotic monotherapy in long-term inpatients with schizophrenia and related disorders. The SwAP trial II: Results on side effects.

Objective: This study examined the effects of switching antipsychotic polypharmacy (APP) to antipsychotic monotherapy (APM) on various side effects in inpatients with schizophrenia. Side effects of interest included psychic, autonomic, and sexual symptoms, as well as metabolic side effects and movement disorders.

Method: A 9-month parallel randomized open-label clinical trial was conducted involving 136 chronic inpatients from two psychiatric hospitals in the Netherlands.

Movement Disorders and Mortality in Severely Mentally Ill Patients: The Curacao Extrapyramidal Syndromes Study XIV.

Background And Hypothesis: There is a substantial gap in life expectancy between patients with severe mental illness (SMI) and the general population and it is important to understand which factors contribute to this difference. Research suggests an association between tardive dyskinesia (TD) and mortality; however, results are inconclusive. In addition, studies investigating associations between parkinsonism or akathisia and mortality are rare.

The effect on relapse rate and psychiatric symptomatology: Switching a combination of first- and second-generation antipsychotic polypharmacy to antipsychotic monotherapy in long-term inpatients with schizophrenia and related disorders. A pragmatic randomized open-label trial (SwAP trial).

Background: There is little evidence to support the use of antipsychotic polypharmacy, and there are concerns about safety and side effects. Nonetheless, it is commonly used in the treatment of long-term inpatients with schizophrenia. This study investigated the effects of switching from a combination of first- and second-generation antipsychotics (FGA and SGA) to monotherapy (FGA or SGA) on relapse rates and psychiatric symptomatology.

Borderline or Schizotypal? Differential Psychodynamic Assessment in Severe Personality Disorders.

Considerable overlap in symptoms between patients with borderline personality disorder (BPD) and schizotypal personality disorder (STPD) complicates personality diagnostics. Yet very little is known about the level of psychodynamic functioning of both personality disorders. Psychodynamic assessment procedures may specify personality characteristics relevant for differential diagnosis and treatment planning.

Instrumental measurements of spontaneous dyskinesia and schizotypy in subjects with auditory verbal hallucinations and healthy controls.

Spontaneous dyskinesia is associated with non-affective psychosis. Few studies investigated dyskinesia in individuals with subclinical psychotic experiences. We examined dyskinesia using instrumental measurements of force variability in 34 individuals with frequent auditory verbal hallucinations but without a clinical psychotic disorder and 31 matched healthy controls.

Increased psychophysiological parameters of attention in non-psychotic individuals with auditory verbal hallucinations.

Objective: Schizophrenia is associated with aberrant event-related potentials (ERPs) such as reductions in P300, processing negativity and mismatch negativity amplitudes. These deficits may be related to the propensity of schizophrenia patients to experience auditory verbal hallucinations (AVH). However, AVH are part of extensive and variable symptomatology in schizophrenia.
